Added tests, info about new feature gate in error message, fixes from review
Added basic e2e test
Added unit tests
Ran hack/update-featuregates.sh
Tolerate updates to existing resources after disabling feature gate
Added feature gate to versioned_kube_features.go
Fixed existing tests
Use PodValidationOptions for validation instead of using feature gate directly
Relaxed validation for allowing zero in prestop hook sleep action
Test today uses deprecated method PollImmediate, which does not return errors
from context, this commit tries to fix this using instead PollUntilContextTimeout.
Kubernetes e2e suite: [It] [sig-node] Variable Expansion should fail
substituting values in a volume subpath with absolute path [Slow]
[Conformance] test takes 37 seconds to run
We previously skipped this test because Docker did not support mounting
individual files in Containers.
Since then, support for Docker has been removed, and containerd on Windows
supports this feature. We can run this test on Windows.
We have "-kube-test-repo-list" command line flag to override the image registry. If we store it in global variable, then that overriding cannot take effect.
And this can cause puzzling bugs, e.g.: containerIsUnused() function will compare incorrect image address.
This changes the text registration so that tags for which the framework has a
dedicated API (features, feature gates, slow, serial, etc.) those APIs are
used.
Arbitrary, custom tags are still left in place for now.
The sysctl tests have to be skipped when the node components are running in UserNS,
because the tests fail due to `open /proc/sys/kernel/shm_rmid_forced: permission denied`
(as expected).
Can be verified with Rootless kind (https://kind.sigs.k8s.io/docs/user/rootless/):
```
dockerd-rootless-setuptool.sh install
: The following steps are added because 'kubetest2 kind --build' does not seem to build e2e.test and ginkgo
make WHAT=test/e2e/e2e.test
make ginkgo
cp -f _output/bin/{e2e.test,ginkgo} _output/dockerized/bin/linux/amd64
kubetest2 kind --build --up --down --test=ginkgo -- \
--use-built-binaries \
--focus-regex='\[NodeConformance\]' \
--skip-regex='\[Environment:NotInUserNS\]'
```
Test with the following host environment:
- kubernetes-sigs/kind@ac28d7fb19 (main)
- kubernetes-sigs/kubetest2@89f09b65e8 (master)
- Docker 24.0.6
- Ubuntu 22.04 amd64, kernel 5.15
