* apiserver/storage/continue: intro PrepareContinueToken
PrepareContinueToken prepares optional
parameters for retrieving additional results for a paginated request.
This function sets up parameters that a client can use to fetch the remaining results
from the server if they are available.
* apiserver/storage/etcd3: refactor to use PrepareContinueToken
v1beta3.ClusterConfiguration.APIServer.TimeoutForControlPlane
must be migrated to {Init|Join}Configuration.Timeouts.
.ControlPlaneComponentHealthCheck.
To achieve this sort of cross-Kind migration do the following:
- Use a temporary, thread-safe variable in timeoututils.go
- Make the order of GVKs in documentMapToInitConfiguration
deterministic.
Flags for kubeadm init such as --apiserver-extra-args prior
to v1beta4 used a map[string]string for pflag.Value storage. This no
longer works since v1beta4 extra args are a slice of Arg.
Add a new flag type argSlice and implement a solution for
parsing these flags.
At the same time deprecate these flags and show a warning
that users should use config.
Instead of defaulting ExtraEnvs for CP components to an empty
slice when converting from/to v1beta3 keep it nil.
This allows for expecting a nil value in the internal
config, similarly to ExtraArgs.
- Include some more examples related to v1beta4 in the doc.go.
- Fix some typos in v1beta4 field comments.
- Add missing JSON tag for UpgradeConfiguration.Apply.SkipPhases.
e2e_node test depend on very specific shared state (node state).
Pod leakages between tests oftentimes cause the test preconditions
to be silently corrupted, causing hard to debug CI failures.
Use the new facility to annotate pods with test owner (= the
test code which created the test) to help debug these failures.
For more context, please check the conversation in #123468

e2e_node test depend on very specific shared state (node state).
Pod leakages between tests oftentimes cause the test preconditions
to be silently corrupted, causing hard to debug CI failures.
We add the option to add an annotation to pods which records
the code line (source code:line) which triggered the pod creation,
so it becomes easier to track which test needs better cleanup.
The relevant e2e framework code is used in all the e2e suites,
so to minimize any unwanted consequences we make the feature
opt-in, planning to enable it initially (and likely only)
in the e2e_node tests.

After the introduction of v1beta4 if the user inputs the old
v1beta3 discovery timeout the value is ignored. Fix that
by introducing a conversion to v1beta4.

- Extract watchWithResync to simplify ListAndWatch
- Wrap watchHandler with two variants, one for WatchList and one for
just Watch.
- Replace a bool pointer arg with a bool arg and bool return, to
improve readability.
- Use errors.Is to satisfy the linter
- Use %w to wrap the store.Replace error, to allow unwrapping.
The watch.Interface design is hard to change, because it would break
most client-go users that perform watches. So instead of changing the
interface to be more user friendly, this change updates the method
comments to explain the different responsibilities of the consumer
(client user) and the producer (interface implementer).
