Quite a few images are only used a few times in a few tests. Thus,
the images are being centralized into the agnhost image, reducing
the number of images that have to be pulled and used.
This PR replaces the usage of the following images with agnhost:
- fakegitserver
- hostexec
- liveness
- logs-generator
- no-snat-test
- no-snat-test-proxy
- port-forward-tester
Basically conformance test checks the target k8s cluster works all
features which are specified in each test and that should not depend
on any condition.
This adds checking that conformance test should not call any Skip
methods. And it detects the existing conformance test
"creating/deleting custom resource definition objects works"
calls framework.SkipUnlessServerVersionGTE(). So this removes the
Skip also.
- moves these helper functions into e2e/framework/auth
- removes logging from helper functions
- in some cases explicitly returns errors that were implicitly
ignored/logged. In the situations where they should be ignored,
we explicitly check that the condition is met before ignoring it.
- fixes references of these methods to use the right package and
return values
Because the code was moved, golint is now active. Because users of the
code must adapt to the new location of the code, it makes sense to
also change the API at the same time to address the style comments
from golint ("struct field ApiGroup should be APIGroup", same for
ApiExtensionClient).
There are two reason why this is useful:
1. less code to vendor into external users of the framework
The following dependencies become obsolete due to this change (from `dep`):

2. works around https://github.com/kubernetes/kubernetes/issues/75338
which currently breaks vendoring
Some recent changes to crd_util.go must now be pulling in the broken
k8s.io/apiextensions-apiserver packages, because it was still working
in revision 2e90d92db9 (as demonstrated by
586ae281ac).
This change modifies kubectl run e2e test to remove a race condition
where kubectl run might complete before we can scrape the logs off via
attach.
Tested via running the e2e tests a few times on gce via kubetest.
Some tests use .yaml files to deploy pods, which have hardcoded
images. Those images cannot be used for Windows containers.
The image names can be injected by the tests themselves, based on
the configured registries.
The new test/e2e/framework/testfiles package makes it possible to
write tests that do not depend on a specific way of providing
additional test files at runtime. Such tests and the framework are
then more easily reused in other test suites.
In the test/e2e suite file access is enabled based on the existing
"repo-root" command line parameter and the built-in bindata. Tests
using the new API will first check for files under "repo-root" and
then fall back to the builtin data. This way, users of a test binary
can modify those files without having to rebuild the binary.
"repo-root" is still needed because at least some tests check for
additional files (secret.yaml, via ingress_utils.go) that are not part
of the upstream source code and thus may or may not be built into a
test binary.
Tests using bindata or repo-root directly get modified to use the new
API, or removed when they are obsolete: test/e2e/examples.go depended
on files that were removed in
https://github.com/kubernetes/kubernetes/pull/61246 and thus can no
longer be run in Kubernetes. Moving the tests to kubernetes/examples
is tracked in https://github.com/kubernetes/examples/issues/214.
The file removal did not break the automated E2E testing probably
because the tests are under the Feature:Example tag and thus not
enabled during normal CI runs.
Removing also the obsolete tests makes it simpler to rework the
"repo-root" setting because less code uses it.
