`kubectl scale` calls visitor two times. Second call fails when
the piped input is passed by returning an
`error: no objects passed to scale` error.
This PR uses the result of first visitor and fixes that piped
input problem. In addition to that, this PR also adds new
scale test to verify.
In order to promote kubectl alpha events to beta,
it should at least support flags which is already
supported by kubectl get events as well as new flags.
This PR adds;
--output: json|yaml support and does essential refactorings to
integrate other printing options easier in the future.
--no-headers: kubectl get events can hide headers when this flag is set for default printing.
Adds this ability to hide headers also for kubectl alpha events.
This flag has no effect when output is json or yaml for both commands.
--types: This will be used to filter certain events to be printed and
discard others(default behavior is same with --event=Normal,Warning).
Fix rollout history bug where the latest revision was
always shown when requesting a specific revision and
specifying an output.
Add unit and integration tests for rollout history.
validate flag does not have default value defined when there is no
parameter passed, therefore it tries to use next irrelevant flag.
This PR defines NoOptDefVal for validate flag which is set "strict".
- Also update test-cmd.sh to pass a signing ca to the kube controller
manager, so CSRs work properly in integration tests.

ARTIFACTS environment variables if KUBE_JUNIT_REPORT_DIR is not set.
Add missing record_command to a couple of tests in legacy-script.sh.
Fix some typos in /test/cmd/README.md
When CRDs are deleted, discovery local cache is not invalidated.
This brings about `resource not found` error when new CRD with same name is created
with different fields(ie. changing scope from cluster-wide to namespaced).
Because this already deleted CRD still stays in serverresources.json and kubectl tries to use it.
This local cached files have 10 minutes TTL. After deletion, if user waits 10 minutes,
files will be expired and deleted and there will be no errors. However, 10 minutes is a long time
and cache needs to be invalidated after deletion occurs.
This PR adds a document into delete command by noting that there might be a need to invalidate discovery
cache when CRD is deleted. In addition to that this PR adds a test to catch this behavior.
This currently covers two cases:
- "kubectl list" (the regression from https://github.com/kubernetes/kubernetes/issues/107012)
- "kubectl get pods/no-such-pod" (no particular reason except that the output
should be deterministic)
In contrast to some other tests that check for strings inside the
output (run_deprecated_api_tests) or compare after
sorting (run_kubectl_version_tests), stdout, stderr and the return code must
match exactly.
This ensures that there is no extra, unexpected output and that the right
output stream is used.
cli.Run was an attempt to elliminate error handling in Kubernetes
commands. However, it had to rely on heuristics that are not necessarily right
for all commands.
kubectl is one example which has its own error printing code that should be
used in all cases after a command failure. It now gets used also for
`--warnings-as-errors`. Previously, that caused the following message to be
logged at the end:
E0110 16:56:01.987555 202060 run.go:120] "command failed" err="1 warning received"
Now it ends with:
error: 1 warning received
