feat(cli): render workload views as a table, json or yaml - #306
Merged
Conversation
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>
Render a set of workload views in the format the -o flag selects. The table uses the standard kubectl tab writer and elides a long COMPONENTS cell so the later columns stay aligned; wide adds the origin of the resolving definition. Machine output is always an array, including for a single workload, so a consumer never branches on shape. The empty-result notice goes to stderr and is suppressed entirely for json and yaml, so piping into jq does not choke on empty input. 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. Signed-off-by: Roee Gil <roee.gil@run.ai>
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. Signed-off-by: Roee Gil <roee.gil@run.ai>
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. Signed-off-by: Roee Gil <roee.gil@run.ai>
#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. Signed-off-by: Roee Gil <roee.gil@run.ai>
The commit that added the SPDX headers stripped the final newline from all six files, so each ended mid-line. Text files end with one. Signed-off-by: Roee Gil <roee.gil@run.ai>
Make the output switch exhaustive. A format that is set but unrecognized now
errors instead of quietly rendering a table, which would misrepresent what the
caller asked for. An unset Output still renders the default table, so Options{}
stays usable as-is.
Assert the table by its split cells rather than by substring. The old check
could not fail: "NAME" is a substring of "NAMESPACE", so the assertion held
whether or not the column was there. Comparing the parsed header and row pins
the column set, its order, and the values.
Also name encode for what it does, record why only its JSON branch adds a
trailing newline, and build the row cells as a literal rather than appending to
a fresh slice.

#309 landed a generic Render in the same package and file this branch added its own to. Keep main's: it is generic over the item type, delegates the human table to a callback, and reports an unsupported format with a sentinel callers can match. This branch's copy is deleted rather than reconciled. What was specific to a workload view moves to RenderWorkloads, which supplies the table callback and keeps the namespace-aware empty notice on stderr. The machine formats now go through the shared Render, so get and definitions emit the same shapes. Tests move to Ginkgo, the convention the package arrived at with #309.

Wrap the tab writer flush, so a failed table write says which write failed, the way renderDefinitions already does. Move the specs to the internal package, per the guideline that a test file sits in the package it covers. The two generator test files #309 merged use the external package and still need the same change. Signed-off-by: Roee Gil <roee.gil@run.ai>
On an empty result the notice is the entire output, and unlike the writes into the tab writer, nothing flushes it later to surface the error. Swallowing it meant a command that said nothing still exited successfully, so a script redirecting stderr to a full disk would read that as a clean run. Build the message once and return the write error wrapped. Signed-off-by: Roee Gil <roee.gil@run.ai>

#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.

What does this PR do?
Third of a five-PR stack that adds
karta get. Renders a set of workload views in the format-oselects.NAME NAMESPACE PHASE AGE, using the standard kubectl tab writer.ORIGIN, the source of the resolving definition (catalog or cluster).Two deliberate departures from kubectl, both aimed at machine consumers:
jq -s; Karta views are not Kubernetes objects, so there is noListkind to emit and no reason to reproduce it. One shape means a consumer never branches.[]on stdout instead. Piping intojqdoes not choke on empty input.An unset creation timestamp renders
<unknown>rather than saturating to292y, which is reachable for any view not built from a live API read.Follows the scope cut in #305
The base PR deferred the component breakdown and the aggregate GPU total pending the output contract in #206, so
Viewno longer carriesComponentsorGPUs. This branch has been updated to match:COMPONENTSandGPUcolumns are gone from the table.role(count)formatting, its width budget, and the elision that kept later columns aligned all read fields that no longer exist.They return alongside the fields rather than living on as dead code against a struct that cannot feed them. The elision behaviour is the part worth restoring carefully - Milvus declares eighteen components, and a multi-instance component takes its name from the instance key, which can outgrow the cell on its own.
