Success! You must now do the following (you may want to cut and paste these
|
|
instructions elsewhere):
|
|
|
|
1) pushd ${KUBE_BUILD_DIR}; build/push-official-release.sh ${KUBE_RELEASE_VERSION} ${KUBE_RELEASE_TYPE}
|
|
|
|
2) Release notes draft, to be published when the release is announced:
|
|
|
|
a) Title:
|
|
|
|
Release ${KUBE_RELEASE_VERSION}
|
|
|
|
b) Template for the description:
|
|
|
|
## [Documentation](http://releases.k8s.io/${RELEASE_BRANCH}/docs/README.md)
|
|
## [Examples](http://releases.k8s.io/${RELEASE_BRANCH}/examples)
|
|
## Changes since <last release> (last PR <last PR>)
|

3) Ensure all the binaries are in place on GCS before cleaning, (you might
|
|
want to wait until the release is announced and published on GitHub, too).
|
|
|
|
4) make clean; popd; rm -rf ${KUBE_BUILD_DIR}
