Resource consumer might use slightly more CPU than requested. That
resulted in HPA sometimes increasing size of deployments during e2e
tests. Deflake tests by:
- Scaling up CPU requests in those tests. Resource consumer might go a fixed
number of milli CPU seconds above target. Having higher requests makes
the test less sensitive.
- On scale down consume CPU in the middle between what would generate
recommendation of expexted size and 1 pod fewer (instead of righ on
edge beween expected and expected +1).
Some variables were int32 but always cast to int before use. Make them
int.
The service account authenticator isn't the only authenticator that
should respect API audience. The authentication config structure should
reflect that.
If dig fails to reach the DNS, it will output errors to stdout, which
can cause the test -n to falsely pass:
ubuntu@ubuntu:~$ dig +notcp +noall +answer +search kubernetes.default A
;; connection timed out; no servers could be reached
command terminated with exit code 9
ubuntu@ubuntu:~$ test -n "$(dig +notcp +noall +answer +search kubernetes.default A)" && echo OK
OK
This patch solves this issue by making sure the dig command actually succeeds
before checking its output.
The test "should run with the expected status" passes with and without
the set SELinuxOptions, but removing it will ensure that the test will
be able to run and pass on Windows nodes as well.
This change updates the ETCD storage test so that its data is
exported. Thus it can be used by other tests. The dry run test was
updated to consume this data instead of having a duplicate copy.
The code to start a master that can be used for "one of every
resource" style tests was also factored out. It is reused in the
dry run test as well.
This prevents these tests from drifting in the future and reduces
the long term maintenance burden.

In some storage tests, kubelet is stopped first and the test check node
NotReady state. However, if it fails to have this state, kubelet could
not be restarted because the defer function is placed after the stop
kubelet command. This PR fixes this issue.
Make CreatePrivilegedPSPBinding reentrant so tests using it (e.g. DNS) can be
executed more than once against a cluster. Without this change, such tests will
fail because the PSP already exists, short circuiting test setup.
