Configuring Azure Blob Storage for Integrated Docker Registry - Persistent Storage Examples | Installation and Configuration

Overview

This topic reviews how to configure Azure Blob Storage for OpenShift integrated Docker registry.

Before You Begin

Create a storage container using Microsoft Azure Portal, Microsoft Azure CLI, or Microsoft Azure Storage Explorer. Keep a note of the storage account name, storage account key and container name.
Deploy the integrated Docker registry if it is not deployed.

Overriding Registry Configuration

To create a new registry pod and replace the old pod automatically:

Create a new registry configuration file called registryconfig.yaml and add the following information:

  version: 0.1
  log:
    level: debug
  http:
    addr: :5000
  storage:
    cache:
      blobdescriptor: inmemory
    delete:
      enabled: true
    azure: (1)
      accountname: azureblobacc
      accountkey:  azureblobacckey
      container: azureblobname
  auth:
    openshift:
      realm: openshift
  middleware:
    registry:
      - name: openshift
    repository:
      - name: openshift
        options:
          acceptschema2: false
          pullthrough: true
          enforcequota: false
          projectcachettl: 1m
          blobrepositorycachettl: 10m
    storage:
      - name: openshift

1	Replace the values for `accountname`, `acountkey`, and `container` with *storage account name, storage account key, and storage container name* respectively.

Create a new registry configuration:

$ oc secrets new registry-config config.yaml=registryconfig.yaml

Add the secret:

$ oc volume dc/docker-registry --add --type=secret \
    --secret-name=registry-config -m /etc/docker/registry/

Set the REGISTRY_CONFIGURATION_PATH environment variable:

$ oc set env dc/docker-registry \
    REGISTRY_CONFIGURATION_PATH=/etc/docker/registry/config.yaml

If you already created a registry configuration:
1. Delete the secret:
  $ oc delete secret registry-config
2. Create a new registry configuration:
  $ oc secrets new registry-config config.yaml=registryconfig.yaml
3. Update the configuration by starting a new rollout:
  $ oc rollout latest docker-registry
