This repo was previously the core Kubernetes tracking repo for
OKD, and where OpenShift's
hyperkube and openshift-test binaries were maintained. As of July
2020, the purpose and maintenance stratety of the repo varies by
branch.
These branches no longer include the code required to produce
hyperkube binaries, and are limited to maintaining the openshift-tests
binary. Responsibility for maintaining hyperkube has transitioned to
the openshift/kubernetes
repo.
Backports and carries against upstream should be proposed to
openshift/kubernetes. If changes merged to openshift/kubernetes
need to land in origin, it will be necessary to follow up with a PR
to 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 origin (e.g. master in
openshift/kubernetes is vendored into master in origin).
NOTE: Vendoring of the master and release-x.x branches of
openshift/kubernetes into the equivalent branches in origin is
intended to be temporary. At some point in the near future, origin
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
openshift/kubernetes rebases.
These origin branches vendor k8s.io/kubernetes and some of its
staging repos (e.g. k8s.io/api) from our
openshift/kubernetes fork.
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 origin, the
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 openshift/kubernetes:
$ 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
script:
$ hack/update-kube-vendor.sh <branch name or SHA> github.com/myname/kubernetesOnce the script has executed, the vendoring changes will need to be committed and proposed to the repo.
Releases prior to 4.6 continue to maintain hyperkube in the origin
repo in the release-4.x branches. Persistent carries and backports
for those branches should continue to be submitted directly to
origin. openshift/kubernetes is not involved except for rebases.
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 openshift-tests binary.
To build the test binary, run make.
To run a specific test, or an entire suite of tests, read test/extended/README for more information.
hack/update-external-example.sh will pull down example files from external
repositories and deposit them under the examples directory.
Run this script if you need to refresh an example file, or add a new one. See
the script and examples/quickstarts/README.md for more details.
