Fork-local pull request, opened to get a CodeRabbit review without running openshift CI. The upstream equivalent is openshift#122.

Eleven commits. The shell half of making e2e-azure-operator mean something: the job exists in openshift/release as of #84758 and its test step runs hack/ci-e2e-azure.sh, which does not exist yet, so the job fails with exit 127.

The scripts are a port of ones that stood Azure BGP up by hand in August, reworked around a single rule that the AWS libraries in openshift#84 are built on: a read that failed is not an answer. The originals wrote 2>/dev/null || true on nearly every read, so an expired login came back as "there is no Route Server", which the create script acts on by building a second one and the delete script acts on by reporting success over the first. Every read now goes through az_query, and existence checks are filtered lists rather than shows, because a show cannot distinguish "it is gone" from "the question failed".

hack/lib/ci.sh sourced hack/aws/lib.sh and installed the aws CLI unconditionally, so no other cloud could use it. It is split into a cloud-neutral part plus hack/aws/ci.sh and hack/azure/ci.sh. Behaviour is unchanged, checked by running all three AWS entry points from a git archive of the pre-change tree and from the working tree: identical output, identical exit codes.

What this does not do: there is no Azure suite yet, so hack/ci-e2e-azure-run.sh stands the estate up, writes a generated profile and then exits non-zero saying why. test/e2e/azure does not exist, and the operator cannot obtain Azure credentials in a cluster, having no counterpart to awsplatform.ResolveCredentials and no CredentialsRequest. A job that goes green having tested nothing is worse than one that is honestly red.

Test plan

hack/lib-test.sh goes from 79 assertions to 121, with oc, aws and az stubbed. Every commit was verified independently by extracting hack/ at that commit into a fresh directory and running the tests and shellcheck there, not just at the tip.

Exercised end to end against a 4.22.12 IPI cluster in centralus, three masters and three workers. Route Server create 910s, rerun adopting everything 11s. With the operator built from this branch and run out of cluster, six conditions True, one peer group keyed on the Route Server with both addresses and ebgpMultiHop set, three Azure peerings at ASN 65001, and six of six BGP sessions Established. Teardown removed the peerings in 4m39s and the estate in 417s, leaving the vnet byte for byte as the installer built it, checked directly rather than from the script's own summary. A second delete run converged to "already gone" in 11s.

Two findings came from running it rather than reading it. provisioningState reports Succeeded while virtualRouterIps is still empty, so readiness is the addresses and nothing else, and adopting on provisioningState would hand back a Route Server nothing can peer with. And hack/delete-e2e-crs.sh defaults to a 120s finalizer budget, which suits AWS and not this: the operator deletes peerings one at a time at about 1m33s each, so it gave up a third of the way through, cleared the finalizer by hand and reported success.

jpinsonneau and others added 3 commits September 8, 2026 17:22
The createOrUpdate helper performed a naive Get→Update without
retry-on-conflict and without checking whether the spec actually
changed. This caused two problems on live clusters:

1. Optimistic concurrency conflicts: when another controller (e.g.
   OVN-K CUDN controller) modified the same object between Get and
   Update, the resourceVersion mismatch caused a conflict error. The
   reconciler marked itself Degraded, which triggered a new reconcile,
   creating a self-sustaining Degraded/Ready flap storm.

2. No-op update loop: even when spec and labels were identical, the
   unconditional Update bumped resourceVersion, which triggered watches
   on CUDN/RouteAdvertisements/FRRConfiguration objects, which triggered
   new reconciles in an infinite loop.

Fix by:
- Wrapping the Update in retry.RetryOnConflict so transient conflicts
  are retried automatically with exponential backoff.
- Adding specUnchanged() to compare spec and labels before updating,
  skipping the write entirely when nothing changed.

Validated on a live OCP cluster with CUDNBgpRouting and CUDNBgpConfig.

📝 Walkthrough

Walkthrough

The change separates cloud-neutral CI helpers from AWS and Azure bootstrap logic. It adds Azure credential resolution through secrets, ambient credentials, or CredentialsRequest resources. Azure gains Route Server provisioning, teardown, profile generation, and end-to-end orchestration. Azure clients now receive resolved credentials. Tests cover the new CI, Azure helper, credential, retry, reconciliation, lifecycle, and end-to-end behavior.

Priority: ➖ Normal

Merge Risk: 🟡 Moderate · up to 08c31

Azure setup and teardown remain vulnerable to several automation failures, and an Azure client initialization failure can now suppress the diagnostics needed to investigate the failed suite. Resolve these issues before merging.

82-104: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Remove the stderr temp file on the failure paths too.

Each die in this function exits before line 104, so the mktemp file stays in the temp directory. A trap-free alternative is to read the error text and delete the file before calling die, or register cleanup with trap ... RETURN. The impact is small because CI containers are discarded, but a developer running these scripts locally accumulates the files.

written to stderr.

In `@hack/azure/create-route-server.sh`:
- Around line 182-186: Update route_server_ready to retry route_server_addresses
for a bounded number of consecutive failures before returning status 2, while
continuing to return success when addresses are found and preserving the
existing empty-address behavior. Use a finite retry limit and ensure persistent
Azure read failures remain failure-safe rather than being treated as readiness.

In `@hack/ci-e2e-azure.sh`:
- Around line 109-111: Update the test launch flow around ci-e2e-azure-run.sh to
explicitly enable Bash monitor mode, start the script directly without setsid,
and remove setsid from the required-command validation. Keep waiting on the
actual background test process so teardown and exit-status handling occur only
after it finishes.

Record signals until test_pid is assigned.

When SIGTERM or SIGINT arrives after the background job starts and before test_pid=$!, on_signal can observe test_pid=0. It starts run_teardown while ci-e2e-azure-run.sh remains alive and can continue creating resources. Record the signal, assign test_pid, then stop the process group before teardown.

Limit the sleep to the remaining retry budget.

Line 84 always sleeps for RETRY_INTERVAL_SECS after the deadline check. A failed attempt near the deadline can therefore delay return by a full extra interval. This violates the caller's budget and can delay Azure teardown.

Proposed fix
-        sleep "${interval}"
+        local remaining=$((deadline - SECONDS))
+        sleep "$(( remaining < interval ? remaining : interval ))"

Increase the Azure package timeout to cover the full sequential suite budget.

The configured polling ceilings total 172.5 minutes on a clean run. Initial cleanup can add 60 minutes when stale resources exist. The 90-minute package timeout can stop recovery or cleanup before its stage timeout expires. Use a 240-minute timeout, or reduce the stage limits.

Do not treat failed Kubernetes reads as absent resources.

These branches silently ignore every Get error. A transient API error or an authorization error skips CR cleanup. The next Create can then fail with AlreadyExists, and namespace deletion can start before the CRs are removed.

Accept only NotFound as absence. Fail the suite for every other error.

hack/lib/ci.sh sourced hack/aws/lib.sh, and its ci_bootstrap exported
AWS_SHARED_CREDENTIALS_FILE and installed the aws CLI unconditionally,
so an Azure or GCP job could use none of it without either a branch
inside that file or a second copy of it that drifts.

What remains in lib/ci.sh knows about no cloud: the kubeconfig prow
leaves in SHARED_DIR, the scratch directory, and its removal. The AWS
half moves to hack/aws/ci.sh, which defines ci_bootstrap as those
pieces plus its own two. The entry points source that instead, which
is the only change to them.

Naming the pieces is what makes them testable. ci_bootstrap as a whole
cannot be called from a unit test, because its last step provisions a
CLI and would fetch sixty megabytes, so the credential handling had no
coverage at all. The eleven assertions added here cover both halves
against temporary directories.

Behaviour is unchanged, measured rather than assumed: all three entry
points produce identical output and identical exit codes before and
after, run against no cluster and an unknown profile.
`az -o tsv` has the same shape as `aws --output text`: tab separated,
and a bare newline for an empty result, which the obvious `| grep .`
filter reports as a failure that then has to be swallowed. So the
Azure scripts want the same helper, and a cloud that does not source
AWS's library should still get it.

Four assertions cover the behaviour and a fifth pins the reason for
the move, by calling it from a shell that has sourced common.sh and
nothing else.

The unquoted expansion is what splits a tool's output into fields, and
the same expansion also expands pathnames. A field carrying * or ?
comes back as whatever the working directory happens to hold rather
than as what the cloud printed, and the caller cannot tell the
difference.

Nothing reaches it today that can trigger this. The callers pass route
table ids, peering names, address prefixes and addresses, none of which
can carry a glob character, so this is a boundary being made honest
rather than a bug being chased: it parses the output of an external
CLI, which is where an assumption about the shape of a value should not
be left implicit. It arrived with the AWS scripts and moved here
unchanged, so the behaviour is older than anything else on this branch.

noglob is scoped to the function with `local -`, so a caller that wants
globbing keeps it. Checked both ways: a field of * survives as *, and
the option is as it was on return.
Cancelling a run does not cancel what Azure is already doing. A create
killed 45 seconds in keeps running server-side, and every delete
attempted against the same resource is then refused with
AnotherOperationInProgress until that create finishes. Three attempts
thirty seconds apart give up after ninety seconds, which is nowhere near
the fifteen minutes a Route Server create takes.

retry_on_azure_conflict is the counterpart of the IncorrectState retry
the AWS scripts already have. It takes a budget in seconds rather than a
count of attempts, because the wait is bounded by whatever was left of
the operation that arrived first, not by a number we can pick in
advance.

Two codes are retried, both observed rather than guessed.
AnotherOperationInProgress, which cleared after 875 seconds on the run
that prompted this, and InternalServerError on the very next attempt,
which a later try survived. Anything else is passed straight back: an
authorization failure will not clear by waiting.
COPY . . copies .git, which in a worktree is a file naming a directory
outside the build context. Copied in, it points nowhere, so the first
git call fails with "not a git repository" and the build stops: the
Dockerfile was observed exiting 128 at the safe.directory line, and
Containerfile.bgp-cloud-connector carries the same line.

Nothing in either build needs the metadata. Both run `go build ...
cmd/main.go`, a file list rather than a package path, and go stamps no
VCS information for those: `go version -m bin/manager` reports the
build as command-line-arguments from a full clone as readily as from a
worktree. The safe.directory line was guarding a git call that
produces nothing, so it goes with the metadata rather than being made
to work.

Verified by building both files from a worktree and the Dockerfile
again from an ordinary clone.
The operator could not authenticate to Azure in a cluster. There was no
CredentialsRequest for Azure anywhere and buildAzurePlatform called
azureplatform.New directly, with no counterpart to
awsplatform.ResolveCredentials, so e2e-azure-operator could not have
passed whatever the shell around it did.

Measured on an IPI cluster: an ordinary pod cannot reach IMDS, curl
returning rc 7 where the same node on the host network gets a token,
and a default install has no service account issuer, so azidentity's
chain has nothing to find.

The secret is read first, because where the cluster has provided a
credential that is the one the operator is meant to use, and reading it
on each resolve is what makes a rotation take effect. Only when there
is none does this fall back to the SDK's chain, which is what serves a
manager run from a desk against an az login, so a desk run asks the
cluster for nothing.

The credential type is named from the secret's shape rather than left
to the chain, which is what cloud-network-config-controller,
cluster-ingress-operator, cluster-image-registry-operator and
machine-api-provider-azure all do. Three reasons beyond consistency:
which credential is in use should be readable from the code; the chain
reaches IMDS, and IMDS is unreachable from a pod, so walking it costs a
timeout; and spec.azure.networkInterfaceClientID means two identities
can be in play at once, which one process-wide chain cannot express.

Asking for a token is the one place this diverges from every other
operator here, and it is deliberate. Constructing a credential proves
nothing: NewDefaultAzureCredential returns one with a nil error when
nothing in its chain can produce a token, and NewClientSecretCredential
accepts a secret it has never tried. Without the retrieval a bad or
absent credential surfaces later from DiscoverEndpoints and is reported
as a discovery failure, which sends whoever reads it to the wrong
subsystem.

The six permissions are what the operator calls and no more. There is
no compute permission: it parses the virtual machine out of the node's
providerID and matches interfaces on VirtualMachine.ID.
openshift-cloud-network-config-controller-azure is the obvious list to
copy and it asks for Microsoft.Compute/virtualMachines/read.

Twelve tests, with the SDK chain and the token retrieval stubbed. They
assert the credential's concrete type rather than any side effect, so
"a federated secret yields a WorkloadIdentityCredential" is checked
directly.

The request is reconciled on the secret path as well, not only where
there is none. Once the cloud credential operator has written the
secret that is the only path taken, so returning the credential there
would freeze the request at whatever an earlier release asked for: a
permission added later would never reach a cluster installed before
it, and nothing in the system would repair that.

A secret the operator cannot use is a CredentialError, as a refused
token already was. Reconcile reads the type to choose between
CloudCredentialsInvalid and CloudDiscoveryFailed, and a secret missing
a key the cloud credential operator writes in every mode is not a
discovery problem: reported as one it sends whoever reads it to the
wrong subsystem. That also makes it terminal, which is the right answer
for a secret that will not grow the key by being asked again.
Each of the three Azure clients built its own from
azidentity.NewDefaultAzureCredential. They take one instead, resolved
once per reconcile from the cluster or from whatever this process
already has.

That is what makes spec.azure.networkInterfaceClientID coherent rather
than incidental. It exists so network interface calls can use a
different managed identity from the Route Server calls, which is two
identities in one process: one passed in, one built locally for the
interfaces. A chain consulted independently by each client cannot
express that, and neither can process environment.

The namespaced Role is the other half, and without it none of this
works in a pod. It granted get on bgp-cloud-connector-aws-credentials
by name and nothing else, so the operator's own ServiceAccount could
not read the Azure secret; the marker names both secrets now, and the
ClusterServiceVersion is regenerated from it. Both halves matter,
because make deploy builds the role from config/rbac whilst OLM
installs from the CSV, and a bundle install missing the rule fails
before it can even raise a CredentialsRequest:

  secrets "bgp-cloud-connector-azure-credentials" is forbidden: User
  "system:serviceaccount:openshift-bgp-cloud-connector:openshift-bgp-
  cloud-connector-controller-manager" cannot get resource "secrets"

Verified in a cluster, not only on a desk. The operator running as its
own ServiceAccount with no ambient credential created a
CredentialsRequest, the cloud credential operator provisioned it, and
the operator read the secret, built a client secret credential from it
and reconciled: six conditions True, six BGP sessions Established.

Writes were then proved separately, because adopting an existing estate
only exercises reads. A Route Server peering deleted behind the
operator's back was recreated 63 seconds later and BGP was back to six
of six within three and a half minutes, with the operator logging the
create against the credential the cluster issued.

Still unexercised: the workload identity branch. Its type selection is
unit-tested and no cluster has run it, because this one resolves to
passthrough and has no service account issuer.
A write Azure refuses does not remove the peering. It keeps the name,
the peer IP and the peer ASN and records provisioningState Failed, so a
comparison over those three fields cannot tell a peering that failed to
apply from a working one. ReconcilePeers compared exactly those three,
and ObservedPeer.ProvisioningState was populated from the API and read
nowhere.

Observed on 10 September against a live cluster. Two concurrent writes
to one Route Server were refused with ConflictError and left two
peerings Failed. The reconcile that followed logged "reconciliation
complete" a second later having called nothing, the configuration
reported Ready with all six conditions True, and four of six BGP
sessions were Established with nothing left in the system that would
ever repair the other two.

Succeeded is the only state that means the peering is in place, so
every other one is treated as absent and rewritten. Transient states
are included deliberately: a rewrite Azure rejects fails that reconcile
and is retried on the next, which is the behaviour we want when
something else is changing our peerings underneath us.

The fixture in TestPeerSetEqual described a peering carrying a peer IP
and ASN with no provisioningState beside them, which is not a shape
ListPeers returns. It passed only while the field was ignored.
az_query is the reason this file exists. The scripts being ported wrote
`2>/dev/null || true` on nearly every read, so an expired login came
back as "there is no Route Server", which the create script acts on by
building a second one and the delete script acts on by reporting success
over the first. It warns and returns non-zero rather than calling die,
because die inside `x="$(az_query ...)"` exits only the substitution and
whether the caller notices then depends on it happening to have errexit
set.

Keeping stderr out of the value matters more on Azure than on AWS: az
writes upgrade notices and breaking-change warnings to stderr on calls
that succeed, so folding them in would put "WARNING: You have 2
update(s) available" inside a resource name. azure_cluster_facts reads
oc under the same rule, sending stderr to a file and using it only for
the diagnostic, because oc writes server warnings on calls that return
0 and that text would otherwise sit inside infra, pass the -n guard and
go on to become ${infra}-rs.

azure_cluster_vnet is where the rule earns its keep. It finds the vnet
by the tag the installer puts on what it owns and falls back to the
name it uses today, but a query that failed and a query that matched
nothing must not both end in a guess: on a cluster whose vnet is named
something else the guess is wrong, and everything built into it lands
where nobody looks. Verified against a live cluster both ways, on the
tag and on a resource group that does not exist.

azure_cluster_facts reads no region, unlike the AWS equivalent. Azure's
infrastructure status carries cloudName, resourceGroupName and
networkResourceGroupName and nothing else, so the region comes off the
resource group through azure_group_location.

az_retry is try for a call a cancelled run could collide with, wrapping
retry_on_azure_conflict the way aws_retry wraps its own and honouring
dry_run alike. Waiting for a read to say the resource is settled does
not work in its place: a Route Server reports provisioningState
Succeeded whilst its addresses are still being allocated, so the read
says yes and the call that follows is refused.
The Azure counterpart of hack/aws/create-route-servers.sh, and the same
model: openshift-install builds a cluster that knows nothing about BGP,
and this bolts the BGP side on.

Singular, because Azure allows one Route Server per virtual network and
presents a redundant pair of addresses for the whole vnet rather than an
endpoint per zone. That is why the operator's Azure discovery emits one
peer group where AWS emits one per availability zone.

It creates what the operator never creates and stops there. The peerings
are the operator's own work and the suite asserts on them, so building
them here would let a completely broken operator adopt them and look
identical to a working one.

Widening the vnet by a /26 is the one thing here that reaches into
infrastructure the installer owns. Azure requires the Route Server to
sit in a dedicated subnet named exactly RouteServerSubnet, minimum /26,
and openshift-install sets the vnet address space equal to
machineNetwork and splits all of it between masters and workers, so a
cluster it built has no room at any machineNetwork size. The widening
is tagged bgp-cloud-connector-added-prefix-<infra> by the same az call
that makes it, so there is no window in which the vnet is wider than
the installer made it with nothing to say who widened it. A prefix that
was already there is adopted and left untagged, because it is not ours
to remove: without that record the teardown cannot tell a prefix we
added from one somebody widened for their own reasons. Keyed on the
cluster, because a vnet the cluster does not own can hold more than one
cluster's estate.

Readiness is the addresses, not provisioningState. Measured eleven
minutes into a fifteen-minute create: the virtual hub already reported
provisioningState Succeeded with virtualRouterIps empty. So the create
waits for the addresses, which also means adopting a Route Server that
an interrupted run left half-built resumes rather than fails.

That wait is an hour rather than twice the measured 15m10s, because the
measurement came from a subscription nobody else was using and CI is
not that: the quota slices are shared, and Azure's own FAQ puts Route
Server deployment at 30 to 60 minutes once a virtual network gateway is
involved. Waiting longer costs nothing when the estate is coming up
anyway, whereas giving up early fails a job that would have passed and
leaves a half-built Route Server behind. Against a budget that size a
single failed read is not a verdict either, so three consecutive
failures count as "not yet" and only a run of them gives up, which
still keeps an expired login from burning the whole hour.

The subscription id is not printed, here or anywhere else in these
scripts. Prow logs for openshift repositories are public, and it is the
direct analogue of the AWS account id that require_aws goes out of its
way not to print; az is already pointed at one subscription and every
lookup is scoped to it, so it is checked rather than kept. The cluster,
resource group and vnet names stay, because they name resources that
exist for the length of one job and they are what makes a log worth
reading.

Rerunning adopts rather than duplicating, which is what makes this
usable whilst iterating: a create measured 910s, and the same script
against the finished estate measured 11s.

The subnet is recorded the same way, and for the same reason.
RouteServerSubnet is a fixed name Azure insists on, so one already in
the vnet was put there by somebody: it is adopted and left untagged,
and the teardown then leaves it alone. Only a subnet this script
created carries the record, in a call of its own because the subnet and
the tag are different resources -- a run interrupted between the two
leaves an untagged subnet, which is the safe way round.
The reverse of the create, and the order is forced. A subnet holding a
Route Server cannot be deleted and an address prefix covering a subnet
cannot be removed, so each step is only possible once the one before it
has finished. Nothing stops at the first failure, because stopping is
how the rest get orphaned; failures are recorded and the exit status
says whether anything survived.

Removing the address prefix as well as the subnet is the point: the
cluster goes back to exactly what openshift-install built. A Route
Server left behind holds the subnet, which holds the vnet, which the
cluster's own deprovision then cannot remove.

A prefix goes only when the tag the create script writes says this
cluster added it. Working the range out instead, from the subnet just
deleted or from the default the create script uses, cannot tell a prefix
we added from one that was already in the vnet and that we merely put a
subnet inside, and removing the second narrows a vnet somebody widened
for their own reasons. Nor is that self-correcting, because Azure will
remove an address range happily as long as no subnet is using it.
Measured against a live vnet both ways: a prefix added with no record
survives, a prefix with the record goes together with the record, and
the installer's own tags are untouched.

Every mutating delete goes through az_retry with a budget of half an
hour, twice the fifteen minutes a create takes, because cancelling a run
does not cancel what Azure is already doing and the wait is bounded by
whatever was left of the create when the cancellation arrived. That is
the case prow produces whenever it cancels a job, so it is the one the
teardown most has to survive. Measured with the budget in place: the
estate torn down in 397s, exit 0, leaving the vnet at 10.0.0.0/16 with
the installer's two subnets and tags, no Route Server anywhere in the
subscription and no orphaned public IP.

The commands it suggests name the network resource group. On a cluster
installed into a vnet it does not own, a pasted teardown that leaves it
out defaults it to the cluster's own group, looks for the vnet there,
does not find it, and leaves the subnet and the address prefix behind
whilst reporting that it removed everything. It stays optional and still
defaults to AZURE_RESOURCE_GROUP, because for a cluster that owns its
vnet the two are the same and asking for both would be noise.

The subscription id is checked rather than kept, for the reason the
create script gives.

The subnet goes under the same rule as the prefix, which until now it
did not: RouteServerSubnet was deleted whenever it was found. It has a
fixed name Azure insists on, so finding one says nothing about who
created it, and a teardown that removes it regardless takes somebody
else's subnet and whatever depended on it. The record is cleared only
once the delete has actually succeeded, so a failed one leaves
something for the next run to find.

An estate created before that record existed carries none, so its
subnet now survives the teardown. Within a job both halves come from
one commit; the case that meets it is an estate built by an older
script and torn down by this one.
The profiles under test/e2e/manifests are written by hand against a
cluster somebody keeps. That cannot work for a job, where the Route
Server is created while the job is running, so the profile is generated
into a temporary directory and E2E_MANIFEST_DIR points the suite at it.
A run then leaves the repository exactly as it found it.

spec.azure names the Route Server rather than its addresses, because
the operator reads virtualRouterIps and virtualRouterAsn from Azure
itself and sets ebgpMultiHop on every neighbour. So the profile carries
no neighbour list at all, unlike the Manual ones.

The ASN checks live here rather than in the create script, because this
is where the ASN is chosen: nothing the estate scripts build depends on
it. They were verified against the Route Server FAQ rather than carried
over on trust, which corrected two things. IANA also reserves
65535-65551, which the 16-bit bound already excludes, and "Azure Route
Server supports only 16-bit (2 bytes) ASNs" confirms that bound. 65515
is the one that matters: a node advertising with the Route Server's own
ASN puts it in the AS_PATH, so every route is discarded by ordinary
loop prevention while the session still reports established.

The far side's ASN is read back and compared rather than assumed, since
both it and localASN are defaults somebody will eventually change one
of, and equal ASNs make the session iBGP.

hack/label-router-nodes.sh named the AWS profile writer as the thing it
has to agree with. There are two now, so it names both.
The shared suite under test/e2e derives every expectation from
spec.bgp.peerGroups, which the CRD requires under platform Manual and
forbids under every cloud, so it serves Manual only and cannot stand in
for Azure. This reads status.peerGroups instead, as a cloud suite has
to.

Five specs, in an Ordered container with setup in BeforeAll so any one
of them can be run on its own with --focus. The configuration reaches
Ready with one peer group keyed on the Route Server carrying both of
its addresses at ASN 65515, one Azure peering per router node at the
cluster's ASN, IP forwarding enabled on every router interface, and a
session Established from every node. Then a peering deleted through the
Azure API is rebuilt, forwarding turned off on an interface is turned
back on, a node taken out of the router selector loses its peering and
gets it back when the labels return, and deleting the configuration is
refused until the routing CR goes, after which every peering is
removed.

Two assertions are there because of what Azure does rather than to be
thorough. Every peering is checked for provisioningState Succeeded: a
write Azure refuses keeps the name, the peer IP and the ASN, so those
three cannot tell a peering that failed to apply from a working one.
And sessions are checked for Established rather than for FRR pods being
Running, which is all the AWS suite checks despite saying otherwise.

E2E-AZURE-04 is what covers the set of router nodes changing, without
which a reconcile that added peerings but never removed them would pass
the suite. It refuses to run with fewer than two router nodes, because
ReconcileNodes reads an empty node list as a transient selector gap
rather than a request to release the estate, so on a single-node
cluster the assertions would hold with the operator having done nothing
at all. It asks for no reconcile of its own either: removing a label is
a change the controller already watches, and the configuration requeues
every five minutes besides, so what is proved there is convergence and
not what drove it.

It talks to Azure through the SDK rather than through the operator's own
RouteServerBackend, for the reason the AWS suite talks to EC2: a suite
that observes through the code under test cannot see a fault in that
code.

Cleanup runs at the start of a run and deliberately nowhere else.
Ginkgo skips the remaining specs in an Ordered container once one
fails, so the deletion spec does not run and whatever broke is left
standing to be read; an AfterSuite would destroy exactly that. Cleaning
up front still makes the suite re-runnable, and covers the case an
AfterSuite cannot reach at all, where a run is killed by Ctrl-C, by go
test's timeout, or by a panic.

Verified against a 4.22.12 IPI cluster in centralus with three router
nodes: Ran 5 of 5 Specs in 1555.458 seconds, 5 Passed | 0 Failed, with
the operator logging Route Server peerings updated at three nodes, then
two, then three again.

Re-runnability was measured separately on the same cluster, twice back
to back with no intervention between: 1817s, then 1705s, both ending
with no CRs, no namespace and no peerings, and the estate still
standing. The second run's cleanup cost nothing on the clean cluster
the first left behind, taking four seconds from launch to the
configuration being applied.

Nearly all of that half hour is Azure applying one write to a Route
Server at a time, at two to four minutes each.
The first CI run of this job failed with the configuration Degraded and
nothing to show for it. hack/ci-e2e-azure.sh tears the estate down
whatever the result, which deletes the configuration and scales the
operator to zero, so by the time prow gathered artefacts the conditions
and the operator's log had both gone. The failure could be narrowed
only to "before credentials were resolved", from a CredentialsRequest
that was absent in the gathered set.

Leaving objects behind for somebody to inspect works at a desk, where
nothing else runs, and not here. The log is the only record that
survives a teardown, so the suite prints.

It prints everything at once rather than the one thing that looks
relevant: the operator's image and replica count, the configuration's
generation, phase and conditions with observedGeneration, the routing
CR and the ClusterUDN and RouteAdvertisements behind it, whether a
CredentialsRequest exists and whether it was provisioned, the keys of
the minted secret, every node the router selector matched with its
address and provider id, the FRRConfigurations and BGP session states,
the peerings Azure actually holds with their provisioning states, IP
forwarding per router interface, warning events, and three hundred
lines of manager log plus the previous container's where it restarted.
A run costs about two hours, so a diagnostic that sends you round again
to ask the next question is worth very little.

ReportAfterSuite covers what ReportAfterEach cannot. A failure in
BeforeSuite runs no spec at all, and the start-of-run cleanup waiting
out a finalizer is exactly the kind of thing that would fail there and
say nothing.

Nothing in any of it asserts, and every step tolerates the clients
being nil, because a failure inside a reporting node would replace the
failure you are trying to read. The Azure clients are checked
separately from the cluster ones: BeforeSuite can abort between
building the two, which leaves a guard on the cluster clients
satisfied and the Azure ones nil.

Verified against a live IPI cluster by pointing the profile at a Route
Server that does not exist: every section fired, the conditions carried
the ARM 404 naming the missing resource, and three hundred lines of
manager log came back.
openshift/release#84758 gives e2e-azure-operator three steps and the
last of them runs hack/ci-e2e-azure.sh. The trio mirrors the AWS one:
ci-e2e-azure-run.sh creates and never removes, ci-e2e-azure-teardown.sh
removes and never creates, and ci-e2e-azure.sh is the only file that
knows both exist and the only one that says "always".

The run stands the estate up, writes a profile describing it and runs
make test-e2e-azure against that profile, the way ci-e2e-aws-run.sh
ends by running its own suite. It does not apply the
BGPCloudConfiguration itself: the suite owns the CRs, and two owners
would mean every suite run began by deleting what the run had just
built and paying for the peerings twice, which on Azure is minutes per
write. Every step before the suite is idempotent, so the same command
serves as the desk loop and a second run adopts what is already there
-- the Route Server adopt measured 11s.

The teardown is a step of its own rather than a trap, because prow
sends TERM and then KILL, and a killed shell runs no trap. It matters
more on Azure than on AWS: a Route Server left behind holds the subnet,
which holds the vnet, which the deprovision then cannot remove. It asks
delete-e2e-crs.sh for 1200s rather than taking its 120s default, which
suits AWS and does not suit this: the operator deletes Azure Route
Server peerings one at a time at about 1m33s each, so three router
nodes took 4m39s. At 120s the script gives up, clears the finalizer by
hand and reports success, and the scale-down immediately after it then
stops the operator part way through its own cleanup.

Note for the release config: with 1200s here and a Route Server delete
that measured 6m57s, a cancelled job no longer fits its 30m0s
grace_period, which has to rise with this.

hack/azure/ci.sh is the credentials half, logging in as the service
principal in the cluster profile -- the same file and the same four
fields openshift-install reads, each read with jq -er so a file missing
one is reported as the malformed file it is rather than reaching az as
--tenant null and coming back as a failed login. It points
AZURE_CONFIG_DIR at the scratch directory, because az keeps its token
cache and profile under $HOME/.azure and a prow container runs as a
random uid whose home it may not own; putting it in the scratch
directory also means the token cache goes away with the run. The client
secret is read into a guarded local and passed straight into the
argument, never printed, and the profile the run echoes has the
subscription id redacted, since prow logs for openshift repositories
are public.

There is no ensure-cli step, unlike AWS. The build root carries no az
and there is no standalone binary to unzip, so the job's image imports
one at build time rather than fetching anything at run time.

The sequencer launches the run under bash job control rather than under
setsid. setsid forks when its caller is already a process group leader,
and $! is then the pid of a parent that exits at once, so wait returns
immediately and the teardown starts deleting a Route Server the create
is still building. That needs monitor mode, which prow's
non-interactive shell does not use; `bash -i hack/ci-e2e-azure.sh` is
the invocation that reproduces it, where the teardown was measured
starting before the test had finished. Job control costs nothing and
cannot fail that way.

The commands these print name AZURE_NETWORK_RESOURCE_GROUP, because on
a cluster installed into a vnet it does not own a pasted teardown
without it looks for the vnet in the wrong group and leaves the subnet
and the address prefix behind whilst reporting that it removed
everything.
ensure_address_prefix looped over the same list twice: once to decide
whether our prefix was already there, and again to collect the others
for the update that replaces the list wholesale. One pass answers both.

The others are now gathered even where the prefix turns out to be
present and the list goes unused, which is what reading the address
space once instead of twice costs.
