* move to using informers for getObjAndCheckCondition
* move to using informers for IsDeleted
* update tests to handle new informer methodology
* set minimum timeout to 1s because informer can't handle less for caching reasons
* fix null return for deletes issue
The following flags, which do not apply to kubectl run,
have been removed:
--cascade
--filename
--force
--grace-period
--kustomize
--recursive
--timeout
--wait
These flags were being added to the run command to support
pod deletion after attach, but they are not used if set, so
they effectively do nothing.
This PR also displays an error message if the pod fails to be
deleted (when the --rm flag is used). Previously any error
during deletion would be suppressed and the pod would remain.
This PR also adds some unit tests for run and attach with and
without the --rm flag. As such, some minor refactoring of the
run command has been done to support mocking dependencies.
This commit removes passing source field as parameter. Instead,
this commit returns error verb and error functions to caller function.
Caller function can add source field by generating correct message.
Before:

After:

This also wipes UID early (suggested by David) and asserts it is set in
BeforeCreate().
It is useful to have the ability to control whether alpha or beta features are
enabled. We can group features under LoggingAlphaOptions and LoggingBetaOptions
because the configuration is designed so that each feature individually must be
enabled via its own option.
Currently, the JSON format itself is beta (graduated in 1.23) but additional
options for it were only added in 1.23 and thus are still alpha:
$ go run ./staging/src/k8s.io/component-base/logs/example/cmd/logger.go --logging-format=json --log-json-split-stream --log-json-info-buffer-size 1M --feature-gates LoggingBetaOptions=false
[format: Forbidden: Log format json is BETA and disabled, see LoggingBetaOptions feature, options.json.splitStream: Forbidden: Feature LoggingAlphaOptions is disabled, options.json.infoBufferSize: Forbidden: Feature LoggingAlphaOptions is disabled]
$ go run ./staging/src/k8s.io/component-base/logs/example/cmd/logger.go --logging-format=json --log-json-split-stream --log-json-info-buffer-size 1M
[options.json.splitStream: Forbidden: Feature LoggingAlphaOptions is disabled, options.json.infoBufferSize: Forbidden: Feature LoggingAlphaOptions is disabled]
This is the same approach that was taken for CPUManagerPolicyAlphaOptions and
CPUManagerPolicyBetaOptions.
In order to test this without modifying the global feature gate in a test file,
ValidateKubeletConfiguration must take a feature gate as argument.
Making the LoggingConfiguration part of the versioned component-base/config API
had the theoretic advantage that components could have offered different
configuration APIs with experimental features limited to alpha versions (for
example, sanitization offered only in a v1alpha1.KubeletConfiguration). Some
components could have decided to only use stable logging options.
In practice, this wasn't done. Furthermore, we don't want different components
to make different choices regarding which logging features they offer to
users. It should always be the same everywhere, for the sake of consistency.
This can be achieved with a saner Go API by dropping the distinction between
internal and external LoggingConfiguration types. Different stability levels of
indidividual fields have to be covered by documentation (done) and potentially
feature gates (not currently done).
Advantages:
- everything related to logging is under component-base/logs;
previously this was scattered across different packages and
different files under "logs" (why some code was in logs/config.go
vs. logs/options.go vs. logs/logs.go always confused me again
and again when coming back to the code):
- long-term config and command line API are clearly separated
into the "api" package underneath that
- logs/logs.go itself only deals with legacy global flags and
logging configuration
- removal of separate Go APIs like logs.BindLoggingFlags and
logs.Options
- LogRegistry becomes an implementation detail, with less code
and less exported functionality (only registration needs to
be exported, querying is internal)
Patch type determination is done by checking existence
of resource in schema and if it exists, it uses strategic merge patch.
Otherwise, like for CRDs, it uses merge patch type.
Currently, this code portion is not easily extensible and this PR
splits required checks into their own function to increase extensibility.
