Getting Kubernetes Builds

You can use hack/get-build.sh to get a build or to use as a reference on how to get the most recent builds with curl. With get-build.sh you can grab the most recent stable build, the most recent release candidate, or the most recent build to pass our ci and gce e2e tests (essentially a nightly build).

Run ./hack/get-build.sh -h for its usage.

To get a build at a specific version (v1.1.1) use:

./hack/get-build.sh v1.1.1

To get the latest stable release:

./hack/get-build.sh release/stable

Use the "-v" option to print the version number of a build without retrieving it. For example, the following prints the version number for the latest ci build:

./hack/get-build.sh -v ci/latest

You can also use the gsutil tool to explore the Google Cloud Storage release buckets. Here are some examples:

gsutil cat gs://kubernetes-release-dev/ci/latest.txt          # output the latest ci version number
gsutil cat gs://kubernetes-release-dev/ci/latest-green.txt    # output the latest ci version number that passed gce e2e
gsutil ls gs://kubernetes-release-dev/ci/v0.20.0-29-g29a55cc/ # list the contents of a ci release
gsutil ls gs://kubernetes-release/release                 # list all official releases and rcs

Install gsutil

Example installation:

$ curl -sSL https://storage.googleapis.com/pub/gsutil.tar.gz | sudo tar -xz -C /usr/local/src
$ sudo ln -s /usr/local/src/gsutil/gsutil /usr/bin/gsutil
