What does this PR do?

Second of a five-PR stack that adds karta get. Adds cli/pkg/workload, which turns a workload object into the view the CLI renders: the root object's identity, the Karta definition that covers its type and where that definition came from, and the workload's normalized phase.

Resolution is spec-only. It reuses the existing chain (resource.NewComponentFactoryFromObject then tree.Build) and never contacts the cluster, so a consumer pays one list per kind and no pod reads.

New package. Per AGENTS.md this needs discussing: the layer is shared with karta describe (#206), which renders from the same struct. If #206 diverges, this collapses back into cli/cmd.

Scope cut since the first review

This PR originally also produced the semantic component breakdown and the aggregate requested GPUs. Both have been removed and will land in a follow-up PR.

The reason is the output contract, not the implementation. #205 says -o json follows the typed-output contract in #206, whose example shapes replicas as {"desired": 4, "ready": 3}. The breakdown here exposed a bare replicas number with no ready count, and ready is live-cluster data this spec-only view cannot produce. Shipping the narrow shape first would mean a breaking JSON change later, so the field is being re-evaluated rather than frozen.

What remains is the part all five PRs agree on: identity, definition and origin, phase.

Consequences worth knowing:

  • View is now Name, Namespace, Kind, APIVersion, CreatedAt, Definition, Origin, Phases.
  • Resolve still builds the tree, because that is what yields the phase.
  • Of the "get" command for workloads #205 table, NAME, KIND, PHASE and AGE are servable from this view. COMPONENTS and GPU are not, until the follow-up.

Summary by CodeRabbit

  • New Features

    • Added CLI workload views showing workload identity, source, creation time, and normalized lifecycle phases.
    • Added support for resolving and displaying multiple workload types, including Deployments, inference services, batch jobs, and GPU workloads.
    • Added representative workload configurations for common Kubernetes and machine-learning scenarios.
  • Bug Fixes

    • Workloads without status information now display an Undefined phase instead of failing or showing inconsistent state.
  • Tests

    • Added automated coverage for workload resolution, supported workload types, metadata, origins, and phase normalization.

Every error exited 1, so a script could not tell an unknown type from an
unreachable cluster. Add an error that carries an exit code, and map usage
failures (invalid flag value, bad arguments, unrecognised command) to a
distinct code.

Cobra reports an unrecognised subcommand only for a non-runnable command and
before validating args, so the root becomes runnable to keep that case inside
the contract. Silencing Cobra's own reporting also silences its usage hint, so
main prints both the hint and the lowercase "error:" prefix the rest of the
CLI's diagnostics use.

Turn a workload object into the view the CLI renders: identity, normalized
phase, the semantic component breakdown, and aggregate requested GPUs, read
through the Karta definition that covers its type. Resolution is spec-only, so
a consumer pays one list per kind and no pod reads.

The catalog forces several rules that are easy to get wrong, each covered by a
test against a real definition: the root carries the pod template for
Deployment and friends, which tree.Build omits; a component the workload does
not use still extracts a zero-valued spec, so emptiness is tested by value; a
component declaring only a minimum falls back to it; spec shapes are mutually
exclusive so a definition naming both a container and a resources path counts
GPUs once; child replicas are already absolute, so a cloned subtree is walked
once; and the GPU total follows the effective pod request Kubernetes schedules
against.

Signed-off-by: Roee Gil <roee.gil@run.ai>
The exit-code work this branch was built on landed on main as its reviewed
version, so take main's side for every conflicted file: usageError/usageArgs,
the UsagePath hint, root suggestions, and the config bypass on a bare root.
ExitNotFound was dropped with it; nothing referenced it.

Main also renamed OriginCommunity to OriginCatalog in #297, which git could not
see as a conflict, so the new workload tests move to the current name.

Drop the per-component breakdown and the aggregate GPU total from the resolved
view. Both need to be re-evaluated against the get (#205) and describe (#206)
designs before they become part of the output contract, so they land in a
follow-up PR rather than ship a shape that has to change.

Removing them takes the whole GPU accounting path with it: the spec shape
handling, the replica fallback, and the tree walk that fed the total. Resolve
still builds the tree, because that is what yields the normalized phase. What
remains is the root object's identity, the definition that covered it, and that
phase.

The tests follow the same cut. The catalog fixtures now pin, per kind, which
definition resolves it and that a status-less manifest reads as Undefined,
rather than GPU arithmetic. nested_test.go went with them: its only assertion
was a GPU total.

The resolved view no longer carries the component breakdown or the aggregate
GPU total; both were deferred out of #305 pending the output contract in #206.
Render what the view still provides and restore the columns with the fields.

This takes the components cell with it: the role(count) formatting, its width
budget and the elision that kept later columns aligned all read fields that no
longer exist. They come back with the breakdown rather than living on as dead
code against a struct that cannot feed them.

Walkthrough

The CLI adds workload view tests and Kubernetes fixtures. It declares Kubernetes and YAML packages as direct dependencies and adds the workload Ginkgo test entry point.

Adds the Ginkgo suite entry point, Kubernetes workload fixtures, and tests for catalog resolution, metadata, supported kinds, undefined phases, and Deployment normalization to Running.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to fca73

This PR adds a localized, spec-only resolved workload view without introducing an actionable merge-blocking risk; it is merge-ready after normal checks and review.

Poem

A rabbit tests each workload view,
With YAML fixtures lined in queue.
The catalog paths now hop along,
While phases settle into song.
Ginkgo greets the suite anew.

Comment thread cli/pkg/workload/view.go Outdated
Add the SPDX and copyright headers the guidelines require to every workload
fixture, not just the two the review flagged: all six were missing them, and
the hand-written fixtures under test/e2e/flows/testdata already carry them.

Move View above undefinedPhase so the main type leads the file.

#305 landed as a squash, so this branch's copies of its commits conflict with
the merged result. Take main's side for every workload file: it carries the
review fixes (SPDX headers on the fixtures, View leading view.go) that this
branch predates.

#305, #306 and #309 all landed as squashes, so this branch's copies of their
commits conflicted with the merged result. Take main's side throughout, and
carry over only what this branch owns: the get command, the clusterAccess seam
its tests use, and registering get in place of the workload tree.

Three things had to be reconciled rather than chosen:

ExitNotFound returns. #304's review dropped it because nothing referenced it;
get is the caller #205 specified, for an unknown type and for no definitions at
all.

The renderer moved. get now calls RenderWorkloads, the workload-specific entry
point, rather than the Render this branch predates.

The view no longer carries a component breakdown or a GPU total, so the table
assertions, the JSON contract assertion and the command's own help text drop
their claims to both. nested_test.go goes for the same reason; main deleted it,
and the merge kept it as a file only this branch had.
