bgp-cloud-connector: give e2e-azure-operator an az and room to tear down - #84831
Conversation
Cancelling a job does not cancel what Azure is already doing. Measured on 2026-09-09: killing a Route Server create 45 seconds in left it running server-side, and every delete was refused with AnotherOperationInProgress until it finished, about fifteen minutes later. The teardown itself then took a further seven minutes. That is the case a grace period exists for, and thirty minutes does not cover it. The job would be killed part way through, leaving a Route Server, the public IP allocated to it, the subnet it holds open and an address prefix added to the cluster's own vnet, all of which then block the deprovision.

- Around line 91-93: Extend the Azure CLI validation step after az version to
invoke the help commands for az network vnet and az login, alongside the
existing routeserver checks, so all required runner-image commands are validated
before E2E starts.

@frobware: now processing your pj-rehearse request. Please allow up to 10 minutes for jobs to trigger or cancel. |
e2e-azure-operator runs hack/ci-e2e-azure.sh, and those scripts drive Azure through az. The build root carries none, and unlike the aws CLI there is no standalone binary to fetch: az is a Python distribution. So it is installed from Microsoft's own repository into an image built FROM src, which keeps the pull request's checkout and the Go toolchain the suite will need. kata-containers and stolostron/capi-tests both do the same, so this follows what already works rather than inventing. Two details are measured rather than copied across. The build root wraps dnf with ART's wrapper, which ignores /etc/yum.repos.d, so the repository has to be written where the wrapper looks as well or the install fails with "Unable to find a match: azure-cli". And packages-microsoft-prod.rpm is what configures the RHEL 9 repository: the older yumrepos/azure-cli path resolves to azure-cli 2.38 from 2022, where this resolves to 2.90. azure-cli-image proves it, with no cluster and no lease, so rehearsing that one job demonstrates the image in seconds rather than forty minutes into an e2e run. It checks the flags the scripts actually pass rather than a couple of command groups, because a renamed flag is the failure worth catching. Two things the first rehearsal taught, both folded in here. az keeps its configuration under $HOME/.azure and a prow container runs as a random uid that does not own its home, so without AZURE_CONFIG_DIR az dies with "PermissionError: [Errno 13] Permission denied: '/.azure'" before doing anything; hack/azure/ci.sh sets it for the same reason, and that reason is now observed in CI rather than inferred. And piping help into grep -q makes grep exit on its first match, az die of SIGPIPE, and under pipefail the pipeline report 120, so a flag that is present reads as missing -- the help is captured and searched instead. All ten checks pass against az 2.90 in an image built locally from this config.

Two changes to
e2e-azure-operator, both needed before it can do anything. The job was added in #84758 and itsteststep runshack/ci-e2e-azure.sh, which is being added in openshift/bgp-cloud-connector#122.Those scripts drive Azure through
az, and the build root carries none. Unlike the aws CLI there is no standalone binary to fetch, because az is a Python distribution, so it is installed from Microsoft's own repository into an image builtFROM src, which keeps the pull request's checkout and the Go toolchain the suite will eventually need.kata-containers(peer-pods) andstolostron/capi-testsboth install az the same way, so this follows what already works here rather than inventing something.Two details in that Dockerfile are measured rather than copied across, and both are worth knowing if it ever needs changing. The build root wraps
dnfwith ART's wrapper, which ignores/etc/yum.repos.d, so the repository has to be written where the wrapper looks as well or the install fails withUnable to find a match: azure-cli. Andpackages-microsoft-prod.rpmis what configures the RHEL 9 repository: pointing at the olderyumrepos/azure-clipath instead resolves to azure-cli 2.38 from 2022, where this resolves to 2.90.The
grace_periodgoes from 30 minutes to an hour, because cancelling a job does not cancel what Azure is already doing. Measured on 9 September against a live cluster: killing a Route Server create 45 seconds in left it running server-side, and every delete was refused withAnotherOperationInProgressuntil it finished about fifteen minutes later, with the teardown itself taking a further seven. At 30 minutes the job is killed part way through that, leaving a Route Server, the public IP allocated to it, the subnet it holds open and an address prefix added to the cluster's own vnet, all of which then block the deprovision.Test plan
azure-cli-imageis a new container test and is the proof. It takes no cluster and no lease, so/pj-rehearse pull-ci-openshift-bgp-cloud-connector-main-azure-cli-imagedemonstrates the image in seconds. It checks the two subcommands the scripts actually depend on rather than justaz version, so a future release of az that drops or renames them fails there rather than forty minutes into an e2e run after an install has been paid for.The image was also built and exercised locally with podman against the same build root before this was raised: az 2.90.0, with
az network routeserver create --hosted-subnet,az network routeserver peering create --peer-ip --peer-asn,az network vnet update --address-prefixesandaz login --service-principalall present.One cost worth naming: the image is about 4.7 GB, which is what installing azure-cli costs. That is the same bargain the other two repositories make.
e2e-azure-operatoritself will still fail, and honestly so. The scripts stand the Route Server estate up and tear it down, but there is no Azure e2e suite yet and the operator cannot obtain Azure credentials in a cluster, sohack/ci-e2e-azure-run.shdeliberately exits non-zero saying exactly that. The job isalways_run: falseandoptional: true.Summary by CodeRabbit
