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 strategy 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.
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
openshift/kubernetes
and origin
repos to ensure that PRs proposed
to 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:
https://github.com/openshift/kubernetes/blob/master/openshift-hack/e2e/annotate/rules.go
Test annotation rules for openshift e2e tests are maintained in:
https://github.com/openshift/origin/blob/master/test/extended/util/annotate/rules.go
Origin vendors the kube rules and applies both the kube and openshift
rules to the set of tests included in the openshift-tests
binary.
In order to update test annotation rules for kube e2e tests, it will be necessary to:
- Update
rules.go
inopenshift/kubernetes
- Bump the version of
openshift/kubernetes
vendored in origin
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/kubernetes
Once the script has executed, the vendoring changes will need to be committed and proposed to the repo.
If the script returns '410 Gone' as per the error that follows, it may be that the golang checksum server does not yet know about the target SHA.
go: k8s.io/kubernetes@v1.21.1 (replaced by github.com/openshift/kubernetes@v1.21.2-0.20210603185452-2dfc46b23003): verifying go.mod: g

The workaround is to set GOSUMDB=off
to disable the checksum
database for the vendoring update:
$ GOSUMDB=off hack/update-kube-vendor.sh <branch name or SHA>
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.
