# Getting Kubernetes Builds

You can use [hack/get-build.sh](http://releases.k8s.io/HEAD/hack/get-build.sh) to or 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.

For example, to get a build at a specific version (v1.1.1):

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

Alternatively, to get the latest stable release:

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

Finally, you can just print the latest or stable version:

```console
./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:

```sh
gsutil cat gs://kubernetes-release/ci/latest.txt          # output the latest ci version number
gsutil cat gs://kubernetes-release/ci/latest-green.txt    # output the latest ci version number that passed gce e2e
gsutil ls gs://kubernetes-release/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:

```console
$ 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
```
