We decided to remove this test, as there's no way to get an upper bound
on its running time. Etcd restart behavior should be tested in
integration or e2e tests.
When job.spec.completions is nil, only
one task needs to succeed for the job to succeed,
and parallelism can be scaled freely during runtime.
Added tests.
Release Note:
This causes two minor changes to the API.
First, unset parallelism previously was defaulted to be
equal to completions. Now it always defaults to 1 if unset.
Second, having parallelism=N and completions unset would previously
be defaulted to 1 completion and N parallelism.
(this is not something we expect people to do, though)
Now, no defaulting occurs in that case, and the job's
behavior is different (any completion causes success).
We don't cope well if a PD is in multiple zones, but this is actually
fairly easy to detect. This is probably justified purely on the basis
that we never want to delete the wrong volume (DeleteDisk), but also
because this means that we now warn on creation if a disk is in multiple
zones (with the labeling admission controller).
This also means that with the scheduling predicate in place, that many
of our volume problems "go away" in practice: you still can't create or
delete a volume when it is ambiguous, but thereafter the volume will be
labeled with the zone, that will match it only to nodes with the same
zone, and then we query for the volume in that zone when we
attach/detach it.
This updates the dockertools.dockerVersion to use a semantic versioning
library to more gracefully support engine versions which include
additional version fields.
Previously, go-dockerclient's APIVersion struct was use which only
handles plain numeric x.y.z version strings. With #19675, the library
was now used on the Docker engine string, however it is possible for the
engine string to include include additional information for beta, rc, or
distro specific builds.
This PR also enables the TestDockerRuntimeVersion test which was
previously just a FIXME and updates it to pass, and be used to test the
version string that cause #20005.
This negates the need for fsouza/go-dockerclient#451, since even with
that change, if a user was running Docker 1.10.0-rc1, this would cause
the kubelet to report it as simply 1.10.0.
out of flaky test.
For last 100+ runs, the test never fail in kubernetes-e2e-gce-flaky build.
The only exception is build 10313, but the failure is caused by previous
flaky test, not this one itself.
