This feature gate was redundant with the `--config` flag, which already
enables/disables loading Kubelet config from a file.
Since the gate guarded an alpha feature, removing it is not a violation
of our API guidelines.
Some stuff in `kubernetes/test-infra` currently sets the gate,
so removing will be a 3 step process:
1. This PR, which makes the gate a no-op.
2. Stop setting the gate in `kubernetes/test-infra`.
3. Completely remove the gate.
This allows the e2e node test framework to generate a kubelet config
file containing the defaults it would typically pass to a test via
flags, rather than passing these defaults as flags.
Changes the Kubelet configuration flag precedence order so that flags
take precedence over config from files/ConfigMaps.
See issue #56171 for more details.
Also modifies e2e node test suite to transform all relevant Kubelet
flags into a config file before starting tests when the
KubeletConfigFile feature gate is true, and turns on the
KubeletConfigFile gate for all e2e node tests. This allows the alpha
dynamic Kubelet config feature to continue to work in tests after
the precedence change.
This file provides the abiliy to specify image project on a per-image
basis and is more extensible for future changes.
For backwards compatibility and local development convenience, the
existing flags are kept and should work.
This reverts commit 2494c77972.
The previous commit, which launches the kubelet under `systemd-run`,
fixes an error in detecting the kubelet's cgroup stats.
Fixes#26979
Also includes other improvements:
- Makefile rule to run tests against remote instance using existing host or image
- Makefile will reuse an instance created from an image if it was not torn down
- Runner starts gce instances in parallel with building source
- Runner uses instance ip instead of hostname so that it doesn't need to resolve
- Runner supports cleaning up files and processes on an instance without stopping / deleting it
- Runner runs tests using `ginkgo` binary to support running tests in parallel

Mark runtime conformance tests as flaky and not run them in jenkins CI.
For #26809
@pwittrock As discussed offline, marking runtime tests as flaky for now. I'm not sure if those tests are required. Testing docker in every Kubernetes PR is un-necessary.
These tests can be run periodically in a separate CI. AFAIK, these tests don't seem to exercise any kube features.
- Add README.md for node e2e tests
- Add support for --cleanup=false to leave test files on remote hosts and temporary instances for debugging
- Add ubuntu trusty instances for docker 1.8 and docker 1.9 to jenkins pr builder
- Disable coreos-beta for jenkins ci since it is failing - need to investigate
- support allocating gce instances from images and running tests against them
- set --hostname-override to match node name
- add jenkins script to source to reproduce jenkins build locally
