#### How to release
|
||||
|
||||
First, run the migration and rollback tests.
|
||||
|
||||
```console
|
||||
$ make build test
|
||||
```
|
||||
|
||||
Next, build and push the docker images for all supported architectures.
|
||||
|
||||
```console
|
||||
# Build for linux/amd64 (default)
|
||||
$ make push ARCH=amd64
|
||||
# ---> gcr.io/google_containers/etcd-amd64:TAG

||||
# ---> staging-k8s.gcr.io/etcd-s390x:TAG

|
||||
|

If you don't want to push the images, run `make` or `make build` instead
