# Kube-Registry with GCS storage backend
|
|
|
|
Besides local file system, docker registry also supports a number of cloud storage backends. Full list of supported backend can be found [here](https://docs.docker.com/registry/configuration/#storage). This document describes how to enable GCS for kube-registry as storage backend.
|
|
|
|
A few preparation steps are needed.
|
|
1. Create a bucket named kube-registry in GCS.
|
|
1. Create a service account for GCS access and create key file in json format. Detail instruction can be found [here](https://cloud.google.com/storage/docs/authentication#service_accounts).
|
|
|
|
|
|
### Pack Keyfile into a Secret
|
|
|
|
Assuming you have downloaded the keyfile as `keyfile.json`. Create secret with the `keyfile.json`...
|
|
```console
|
|
$ kubectl --namespace=kube-system create secret generic gcs-key-secret --from-file=keyfile=keyfile.json
|
|
```
|
|
|
|
|
|
### Run Registry
