Move wait for pressure to subside to AfterEach
so we still wait if the test part of the test for eviction order fails.
Prior to this change, a K8s branch (master as well as release) was
pinned to a GCI milestone. It would pick up the latest GCI release on
that milestone at the time of cluster creation. The rationale was the
K8s users would automatically get the bug fixes in newer versions of
GCI. However in practice, it makes the runtime environment
non-deterministic, and lack of continuous e2e tests mean we would run
into breakages sooner or later.
With this change, each K8s release will pick a specific version
of GCI by default (similar to how the Debian-based container-vm gets used).
Users can override the default version through KUBE_GCE_MASTER_IMAGE and
KUBE_GCE_NODE_IMAGE environment variables.
We expect the default GCI version will be updated relatively frequently stay
updated with newer GCI releases. We can also automate the process to
automatically bump the hard-coded GCI version in future.
This commit enables the dynamic kubelet configuration feature for the
node e2e Jenkins serial tests, which is where the test for dynamic kubelet
configuration currently runs.
This gives the node e2e test binary a --feature-gates flag that populates a
FeatureGates field on the test context. The value of this field is forwarded
to the kubelet's --feature-gates flag and is also used to populate the global
DefaultFeatureGate object so that statically-linked components see the same
feature gate settings as provided via the flag.
This means that you can set feature gates via the TEST_ARGS environment
variable when running node e2e tests. For example:
TEST_ARGS='--feature-gates=DynamicKubeletConfig=true'
This should stop the test from flaking while we figure out why there is
a mismatch between the reported pressure condition and the eviction
manager's decision to evict due to memory pressure.

Node E2E: Move host info around test result.
Discussed offline with @yujuhong and @dchen1107. Currently, the node e2e result is organized as:
```
================================================================
Success Finished Host tmp-node-e2e-b6c375c7-e2e-node-containervm-v20160321-image Test Suite
{ginkgo-output}
{framework-error}
================================================================
```
This makes it painful to find which image the test is failing on. The `{ginkgo-output}` is usually quite long, so we have to scroll mouse up and down to find the host name.
This PR changes the test result to:
```
================================================================
Start Host tmp-node-e2e-b6c375c7-e2e-node-containervm-v20160321-image Test Suite

```
This is not perfect, but much better than before. We can easily find the host name under the ginkgo test result, like this:
```

test/node-e2e: Update CoreOS update disabling
Previously in this saga... #25004
This disables update-engine and locksmithd with ignition instead of

Fortunately, converting our cloud-init to json and calling it "ignition" works quite well 😄
Testing done: I ssh'd in and verified that yes, they're disabled. I didn't wait on the e2e tests to pass, so we'll let this PR check that.

[AppArmor] Promote AppArmor annotations to beta
Justification for promoting AppArmor to beta:
1. We will provide an upgrade path to GA
2. We don't anticipate any major changes to the design, and will continue to invest in this feature
3. We will thoroughly test it. If any serious issues are uncovered we can reevaluate, and we're committed to fixing them.
4. We plan to provide beta-level support for the feature anyway (responding quickly to issues).
Note that this does not include the yet-to-be-merged status annotation (https://github.com/kubernetes/kubernetes/pull/31382). I'd like to propose keeping that one alpha for now because I'm not sure the PodStatus is the right long-term home for it (I think a separate monitoring channel, e.g. cAdvisor, would be a better solution).

This function does not actually attempt to connect to the docker daemon,
it just creates a client object that can be used to do so later. The old

**Please only review the last 3 commits.**
This PR is part of our roadmap to package node conformance test.
The 1st commit is from #30348, it removed unnecessary dependencies in the node e2e test framework, because we've statically linked these dependencies.
The PR refactored the node e2e framework. Moving different utilities into different packages under `pkg/`.
We need to do this because:
1) Files like e2e_remote.go and e2e_build.go should only be used by runner, but they were compiled into the test suite because they were placed in the same package. The worst thing is that it will introduce some never used flags in the test suite binary.
2) Make the directory structure more clear. Only test should be placed in `test/e2e_node`, other utilities should be placed in different packages in `pkg/`.

Node E2E: Remove fatal error in e2e_node_suite_test.go
Addresses https://github.com/kubernetes/kubernetes/issues/30779#issuecomment-240532190.
Currently we run node e2e test in parallel, and ginkgo makes sure that we only initialize test framework in the first test node.
However, because we throw out some fatal error during the initialization. Once there is an fatal error, the first test node will die immediately without reporting any error, and the other nodes will exit because the first node is gone with meaningless error.

Node E2E: Make readiness check handling process exits with 0 exit code.
As is mentioned by @mtaufen:
"there is a problem with the way service `start` is currently implemented in test/e2e_node/e2e_service.go. If the Kubelet exits with status 0 before the health check completes, cmdErrorChan will be closed and, as a result, nil will be read from that channel, and you will return a nil error from `start`."
This PR changes the logic to:
1) If the err channel returns an error, return the error
2) If the err channel returns a nil, ignore it and continue checking readiness.
3) If the err channel is closed before readiness check succeeds, replace it with `blockCh` and continue checking readiness.

Fix killing child sudo process in e2e_node tests
Fixes#29211; re-doing #29380 which was reverted due to cross-platform build failure #29669.
The context is we are trying to kill a process started as `sudo kube-apiserver`, but `sudo` ignores signals from the same process group. Applying `Setpgid` means the `sudo kill` process won't be in the same process group, so will not fall foul of this nifty feature.
~~I also took the liberty of removing some code setting `Pdeathsig` because it claims to be doing something in the same area, but actually it doesn't do that at all. The setting is applied to the forked process, i.e. `sudo`, and it means the `sudo` will get killed if we (`e2e_node.test`) die. This (a) isn't what the comment says and (b) doesn't help because sending SIGKILL to the sudo process leaves sudo's child alive.~~
We do need to use the same 'hack' to access `Setpgid` as the `e2e_node.test` program gets built on Windows (although it doesn't run there).

This test creates three pods with QoS of besteffort, burstable, and
guaranteed, respectively, which each contain a container that tries to
consume almost all the available memory at a rate of about 12Mi/10sec.
The expectation is that eviction will be initiated when the hard
memory.available<250Mi threshold is triggered, and that eviction will proceed
in the order of besteffort, then burstable. Since guaranteed pods should
only be evicted if something charged to the host uses more resources
than were reserved for it, we currently end the test when besteffort and
burstable have both been evicted.
Note that this commit also sets --eviction-hard=memory.available<250Mi
to enable eviction during tests.

* If you run the test locally with `make test-e2e-node`, it will use `-p` ginkgo flag, which uses `(cores-1)` parallel test nodes by default.
* If you run the test remotely or in the Jenkin, the parallelism will be controlled by the environment variable `PARALLELISM`. The default value is `8`, which is reasonable for our test node (n1-standard-1).

Node e2e test framework pre-pulls all images in [image_list.go](bc2f223f5a/test/e2e_node/image_list.go)
All node e2e test should use image from the "image_list". If a test needs new image, we should update the image_list to include the new image.
/cc @kubernetes/sig-node to notice people to use `image_list` when adding test. :)

Start namespace controller in node e2e
Fix https://github.com/kubernetes/kubernetes/issues/28320.
Based on https://github.com/kubernetes/kubernetes/pull/28807, only the last 2 commits are new.
Before this PR, there was no namespace controller running in node e2e test infrastructure. We can not enable the [`delete-namespace`](f2ddd60eb9/test/e2e/framework/test_context.go (L109)) flag in the test framework.
So after the test running, there will be running pod left on the test node. This seems to be acceptable in our test infrastructure because we create an new instance each time.
However, in 1.4 we may want to provide part of the test as node conformance test to the user, they definitely don't want the test to leave tons of pods on their node after test running.
Currently, there is no easy way to only start namespace controller in kube-controller-manager (confirmed with @mikedanese), so in this PR I started a "uncontainerized" one in the test infrastructure.
This PR:
* Started the namespace controller in the node e2e test infrastructure and enable the automatic namespace deletion.
* Change the privileged test to use framework (@yujuhong), so that all node e2e tests are using the framework and test pods will be cleaned up by namespace controller.

Don't repeat the program name in healthCheckCommand.String()
The name is in both `Path` and `Args[0]`, so start printing args at 1.
Also refactor to avoid an extra space character in the output.
I pondered whether `healthCheckCommand.String()` should check if the slice is empty, to avoid a panic, but it didn't check for `Cmd==nil` before.

Change the docker validation node e2e test to use gci-canary-test
This PR changed the continuous docker validation node e2e test to use the image config file introduced in https://github.com/kubernetes/kubernetes/pull/28708. @euank
This PR also changed the gci image family from `gci-preview-test` to `gci-canary-test`. @wonderfly

Node E2E: Make it possible to share test between e2e and node e2e
This PR is part of the plan to improve node e2e test coverage.
* Now to improve test coverage, we have to copy test from e2e to node e2e.
* When adding a new test, we have to decide its destiny at the very beginning - whether it is a node e2e or e2e.
This PR makes it possible to share test between e2e and node e2e.
By leveraging the mechanism of ginkgo, as long as we can import the test package in the test suite, the corresponding `Describe` will be run to initialize the global variable `_`, and the test will be inserted into the test suite. (See https://github.com/onsi/composition-ginkgo-example)
In the future, we just need to use the framework to write the test, and put the test into `test/e2e/node`, then it will be automatically shared by the 2 test suites.
This PR:
1) Refactored the framework to make it automatically differentiate e2e and node e2e (Mainly refactored the `PodClient` and the apiserver client initialization).
2) Created a new directory `test/e2e/node` and make it shared by e2e and node e2e.
3) Moved `container_probe.go` into `test/e2e/node` to verify the change.

Fix a bug in mirror pod node e2e test.
Fixed a bug in test/e2e_node/mirror_pod_test.go. The function 'checkMirrorPodDisappear' returns nil even when the pod does not disappear. It should return a non-nil error.

Support terminal resizing for exec/attach/run
```release-note
Add support for terminal resizing for exec, attach, and run. Note that for Docker, exec sessions
inherit the environment from the primary process, so if the container was created with tty=false,
that means the exec session's TERM variable will default to "dumb". Users can override this by
setting TERM=xterm (or whatever is appropriate) to get the correct "smart" terminal behavior.
```
Fixes#13585
