The log path test is not expected to pass unless the Docker is using the
JSON logging driver, since that's what the log path is trying to find.
When Docker is using the journald logging driver, there will be no JSON
files in the logging directories for it to find.
Furthermore, when SELinux support is enabled in the Docker daemon,
SELinux will prevent processes running inside Docker containers from
accessing the log files owned by Docker (which is what this test is
trying to accomplish), so let's also skip this test in case SELinux
support is enabled.
Tested:
- With Docker daemon started using --log-driver=journald:

Support for custom tls cipher suites in api server and kubelet
**What this PR does / why we need it**:
This pull request aims to solve the problem of users not able to set custom cipher suites in the api server.
Several users have requested this given that some default ciphers are vulnerable.
There is a discussion in #41038 of how to implement this. The options are:
- Setting a fixed list of ciphers, but users will have different requirements so a fixed list would be problematic.
- Letting the user set them by parameter, this requires adding a new parameter that could be pretty long with the list of all the ciphers.
I implemented the second option, if the ciphers are not passed by parameter, the Go default ones will be used (same behavior as now).
**Which issue this PR fixes**
fixes#41038
**Special notes for your reviewer**:
The ciphers in Go tls config are constants and the ones passed by parameters are a comma-separated list. I needed to create the `type CipherSuitesFlag` to support that conversion/mapping, because i couldn't find any way to do this type of reflection in Go.
If you think there is another way to implement this, let me know.
If you want to test it out, this is a ciphers combination i tested without the weak ones:
```
TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305,TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_GCM_SHA256,TLS_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
```
If this is merged i will implement the same for the Kubelet.
**Release note**:
```release-note
kube-apiserver and kubelet now support customizing TLS ciphers via a `--tls-cipher-suites` flag

Fix policy conflict in the CPU manager node e2e test.
**What this PR does / why we need it**:
After graduation of the CPU manager feature to Beta, the CPU manager `none` policy is ON by default. But when the CPU manager is set to use `static` policy in the node e2e test, there will always be a conflict with the policy checkpointed in the disk. This PR fixes that by deleting the state file where required.
Manually tested in an `n1-standard-4` instance with `Ubuntu 16.04` image on GCP, which is the same machine and image type as one of the configs used in the node e2e tests.
Use the following command to run the test locally:
`make test-e2e-node TEST_ARGS='--feature-gates=DynamicKubeletConfig=true' FOCUS="CPU Manager" SKIP="" PARALLELISM=1`

Make cluster e2e non docker specific.
Fixes https://github.com/kubernetes/kubernetes/issues/57979.
This PR:
1) Install `crictl` for GCE GCI/Ubuntu test cluster.
2) Change cluster e2e test to use `crictl`. If `crictl` is not installed, it will fall back to `docker` CLI.
Please note that, this PR:
1) Only installs `crictl` for GCI/Ubuntu image on GCE. If other image maintainers want to support this, it's very easy to install `crictl` `v1.0.0-alpha.0`:
```console
$ wget -O crictl https://storage.googleapis.com/kubernetes-release/crictl/crictl-v1.0.0-alpha.0-linux-amd64
$ chmod +x crictl
// The sha1sum is `075190a36a03beb08065f279693f3e369e70cf99`.
```
2) Only installs `crictl` for test cluster. We may want to install it by default in production cluster after `crictl` is beta in v1.10.

Use GinkgoRecover to avoid panic.
See this in the test:
```
I0111 14:28:31.010] panic:
I0111 14:28:31.010] Your test failed.
I0111 14:28:31.010] Ginkgo panics to prevent subsequent assertions from running.

Explicit kubelet flags
The Kubelet was using the global flag set.
Libraries also often use the global flag set.
There are flags in the Kubelet's usage statement for which the Kubelet does not control registration.
This is bad, we must have full control of our command-line API.
This PR puts a stop to it.
I worked through the Kubelet's usage printout and tracked down the flags.
In the below list, flags with checkboxes are one of:
- explicitly **registered** in this PR
- thought about and outright **rejected**
- thought about and **registered-deprecated** for legacy reasons
For the others we need to figure out whether they should be **registered** or **rejected** or **registered-deprecated**.

```release-note
The Kubelet now explicitly registers all of its command-line flags with an internal flagset, which prevents flags from third party libraries from unintentionally leaking into the Kubelet's command-line API. Many unintentionally leaked flags are now marked deprecated, so that users have a chance to migrate away from them before they are removed. One previously leaked flag, --cloud-provider-gce-lb-src-cidrs, was entirely removed from the Kubelet's command-line API, because it is irrelevant to Kubelet operation.
```
Thanks to @liggitt for being surprised that we didn't already do this.
Thanks to @dashpole for realizing cadvisor flags were leaked after seeing #55863.
Thanks to @tallclair who recognized this problem a long time ago in #19432.
This explicitly registers Kubelet flags from libraries that were
registering flags globally, and stops parsing the global flag set.
In general, we should always be explicit about flags we register
and parse, so that we maintain control over our command-line API.

Node e2e non docker specific
Fixes https://github.com/kubernetes/kubernetes/issues/57977.
Make node e2e test generic to container runtimes.
With this change, other than tests with `[Feature:Docker]`, all tests can run against all CRI container runtimes.
Note that this PR also marks cpu manager test as `Serial`, because it restarts kubelet during the test. It doesn't cause problem in regular node e2e suite today, because it is skipped if node has less than 2 CPUs, which is the case for our test environment. /cc @balajismaniam

Cleanup api service before namespace deletion.
Fixes https://github.com/kubernetes/kubernetes/issues/57486.
https://github.com/kubernetes/kubernetes/pull/57254 helps but is not enough for the fix. After https://github.com/kubernetes/kubernetes/pull/57254, I saw another failure https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/ci-cri-containerd-e2e-ubuntu-gce/1057.
Before, all test after Aggregator test would fail. Now all tests before/after Aggregator tests are passing. However, during the Aggregator test waiting for namespace cleanup, all the other tests are failing. Aggregator test takes 10min to wait for namespace cleanup.
The reason is that, `BeforeEach`s run in LIFO order, `AfterEach`s run in FIFO order. `NewDefaultFramework` inserts an `AfterEach` function to do namespace cleanup.
In the current code, the namespace cleanup `AfterEach` is inserted by `NewDefaultFramework` before `cleanupTest`, it means that the test will try to delete namespace first, and then cleanup the api service. However, as known to us, if api service is not cleaned up, namespace deletion will wait forever.
In this PR, we reverse the `AfterEach` order. A better solution is to put `BeforeEach` and `AfterEach` in an internal `Describe`. However, since we don't have an internal `Describe` in this test, I just reverse the `AfterEach` order directly.

This adds new benchmark tests that measure scheduler latency of pods
that use affinity rules. Specifically, this tests affinity rules with
topologyKey="kubernetes.io/hostname".
Under the default behavior of Go benchmark tests, all our scheduler_perf
benchmark tests run with b.N=1, which is lower than we would like. This
adds a lower bound to b.N so that the results are more meaningful.
The alternative to this change is to always run these tests with the
-benchtime flag set to a duration which will force b.N to increase. That
would cause any test setup to be executed repeatedly as b.N ramps up,
and -timout would probably also need to be set higher.

Collect all the assorted image URLs from e2e tests in one place
utils/image/manifest has an additional `arch` parameter, which determines
whether an image ends in `-$ARCH` (like `-amd64`).
All locations that previously had gcr.io urls referenced in costants or inline
have been updated to refere test/utils/image.
**What this PR does / why we need it**:
Previously, all sorts of `gcr.io/` URLs were scattered all over the E2E tests codebase. This PR unifies them all in one place, making it easier to see what is needed to run the E2E tests, as well as making sure all tests use the same version of docker images.
Heptio is working on a project to get the E2E tests running in airgapped environments. Part of that task is collecting all images in one place. A future PR will allow modification of the registry URLs to point at a private docker registry.
**Special notes for your reviewer**:
Two images, https://github.com/kubernetes/kubernetes/pull/56716/files#diff-e3afa632328a4a5271f4b8578faa34bdL318 and https://github.com/kubernetes/kubernetes/pull/56716/files#diff-7dc1ebd3b2f2f6ca1ff248e6601016a6L104 are now pointing to slightly different images. If this breaks the E2E tests, the variables can be duplicated to restore the old dependencies, and the duplicates can be removed at a later date.

Version bump to etcd v3.2.11, grpc v1.7.5
Fix https://github.com/kubernetes/kubernetes/issues/56114: Update to etcd client 3.2.11
Version bumps:
- etcd from 3.1.10 to 3.2.11
- grpc from 1.3.0 to 1.7.5
- grpc-gateway from v1.1.0-25-g84398b9 to v1.3.0
TODO:
- [x] Apply etcd [3.2 client upgrade guide](https://github.com/coreos/etcd/blob/master/Documentation/upgrades/upgrade_3_2.md)
- [x] Apply grpc API changes in 1.6.0 and 1.7.0 [release notes](https://github.com/grpc/grpc-go/releases)
- [x] bbolt was pulled in transitively, why? We have tests that embed etcd, so we must vendor the etcd server and all it's dependencies.
- [x] Upgrade to containerd v1.0.0? Currently kubernetes depends on containerd v1.0.0-beta.2-159-g27d450a0 which depends on grpc v1.3.0, but containerd v1.0.0 depends on grpc 1.7.2. Not needed. The containerd grpc upgrade required [no code changes](ce3e32680d).
- [x] Fix all failing tests
- [x] Ensure we can safely upgrade grpc to 1.7.5 given that docker and cAdvisor still depend on grpc 1.3.0 (both in the versions we vend and on master for both projects). Should we hold off on this change until we have a docker release that uses gprc 1.7.x?
- [x] Wait for grpc 1.7.5 to be released (it will include https://github.com/grpc/grpc-go/pull/1747). Once released, bump grpc version in this PR and remove workarounds in `hack/godep-save.sh`.
Transitive dependencies on grpc:
- docker depends on grpc, but according to the package dependency graph (`go list -f '{{ .Deps }}'`) there are no dependencies from kubernetes to grpc via docker packages.
- containerd v1.0.0 depends on grpc 1.7.2, we should upgrade to containerd v1.0.0 soon, this can be done in a separate PR
- cadvisor depends on grpc 1.3.0 on master, it should upgrade it to grpc 1.7.5, this can be done in a separate PR
**Release note**:
```release-note
Upgrade to etcd client 3.2.11 and grpc 1.7.5 to improve HA etcd cluster stability.

install the kernel headers should they need to by running "apt-get install

e2e_node: small fixes to setup_host.sh for Ubuntu Trusty
**What this PR does / why we need it**:
Two small fixes for how nsenter is built from source and installed on Ubuntu Trusty:
1. Use mktemp for the creating the build directory instead of a hard coded name
2. Use current (2.31) util-linux instead of 3+ year old version

Fixes#56106

Use k8s.gcr.io vanity domain for container images
Related issue: https://github.com/kubernetes/release/issues/281
```release-note
Use "k8s.gcr.io" for container images rather than "gcr.io/google_containers". This is just a redirect, for now, so should not impact anyone materially.
Documentation and tools should all convert to the new name. Users should take note of this in case they see this new name in the system.
```
The e2e_node test environment setup script is hard coded to pull down a
quite old version of util-linux in order to build nsenter on trusty,
which sadly is well known to not include an nsenter executable.
While "just a test", it's unfortunate to be building from really old
util-linux sources when newer are available.
Signed-off-by: Tim Pepper <tpepper@vmware.com>
There's a bit of a hack in place to insure nsenter is present on Ubuntu
trusty, which doesn't otherwise include it. This downloads util-linux
to a hard coded directory in /tmp which is a bad practice. Even though
"this is just a test case" it should properly use mktemp.

Add brackets around IPv6 addrs in e2e test IP:port endpoints
There are several locations in the e2e tests where endpoints of the
form IPv6:port use IPv6 addresses directly, without surrounding brackets.
Brackets are required around IPv6 addresses in this case, in order to
distinguish the colons in the IPv6 address from the colon immediately
preceding the port.
Also, wherever the curl command might be used with an IPv6 address
surrounded in brackets, the "-g" argument is added to the curl
command line arguments so that the brackets can be interpreted
correctly.
fixes#52746
**What this PR does / why we need it**:
This PR adds brackets around IPv6 addresses when they appear as part of an IPv6-addr:port endpoint
in the e2e tests. This is needed because any connections that attempt to use IPv6-addr:port
endpoint without brackets surrounding the IPv6-addr will fail.
