This repo was previously the core Kubernetes tracking repo for
OKD, and where OpenShift's
openshift-test binaries were maintained. As of July
2020, the purpose and maintenance strategy of the repo varies by
release-x.x branches for 4.6 and above
These branches no longer include the code required to produce
hyperkube binaries, and are limited to maintaining the
binary. Responsibility for maintaining hyperkube has transitioned to
Backports and carries against upstream should be proposed to
openshift/kubernetes. If changes merged to
need to land in
origin, it will be necessary to follow up with a PR
origin that bumps the vendoring.
Branch names are correlated across the 2 repositories such that
changes merged to a given branch in
openshift/kubernetes should be
vendored into the same branch in
openshift/kubernetes is vendored into
NOTE: Vendoring of the
release-x.x branches of
openshift/kubernetes into the equivalent branches in
intended to be temporary. At some point in the near future,
will switch to vendoring origin-specific branches (e.g
origin-4.6-kubernetes-1.19.2) to minimize the scope of backports and
carries that need to be considered in the context of
Test annotation rules
Test annotation rules are used to label e2e tests so that they can be filtered or skipped. For example, rules can be defined that match kube e2e tests that are known to be incompatible with openshift and label those tests to be skipped.
Maintenance of test annotation rules is split between the
origin repos to ensure that PRs proposed
openshift/kubernetes can be validated against the set of kube e2e
tests known to be compatible with openshift.
Test annotation rules for kubernetes e2e tests are maintained in:
Test annotation rules for openshift e2e tests are maintained in:
Origin vendors the kube rules and applies both the kube and openshift
rules to the set of tests included in the
In order to update test annotation rules for kube e2e tests, it will be necessary to:
- Bump the version of
openshift/kubernetesvendored in origin
These origin branches vendor
k8s.io/kubernetes and some of its
staging repos (e.g.
k8s.io/api) from our
Upstream staging repos are used where possible, but some tests depends
on functionality that is only present in the fork.
When a change has merged to an
openshift/kubernetes branch that
needs to be vendored into the same branch in
hack/update-kube-vendor.sh helper script simplifies updating the go
module configuration for all dependencies sourced from
openshift/kubernetes for that branch. The script requires either the
name of a branch or a SHA from
$ hack/update-kube-vendor.sh <openshift/kubernetes branch name or SHA>
The script also supports performing a fake bump to validate an as-yet
unmerged change to
openshift/kubernetes. This can be accomplished by
supplying the name of a fork repo as the second argument to the
$ hack/update-kube-vendor.sh <branch name or SHA> github.com/myname/kubernetes
Once the script has executed, the vendoring changes will need to be committed and proposed to the repo.
Maintenance of release-4.5, release-4.4 and release-4.3
Releases prior to 4.6 continue to maintain hyperkube in the
repo in the
release-4.x branches. Persistent carries and backports
for those branches should continue to be submitted directly to
openshift/kubernetes is not involved except for rebases.
End-to-End (e2e) and Extended Tests
End to end tests (e2e) should verify a long set of flows in the product as a user would see them. Two e2e tests should not overlap more than 10% of function and are not intended to test error conditions in detail. The project examples should be driven by e2e tests. e2e tests can also test external components working together.
All e2e tests are compiled into the
