For administrators

Installing and configuring the ACR plugin

  1. Run the following command to install the ACR plugin:

    yarn workspace app add @janus-idp/backstage-plugin-acr
  2. Set the proxy to the desired ACR server in the app-config.yaml file as follows:

    # app-config.yaml
    target: ''
    changeOrigin: true
    # If you use Bearer Token for authorization, please replace the 'Basic' with 'Bearer' in the following line.
    Authorization: 'Basic ${ACR_AUTH_TOKEN}'
    # Change to "false" in case of using self hosted artifactory instance with a self-signed certificate
    secure: true
  3. Set the authorization using one of the following options:

    • Basic authorization:

      • Navigate to the ACR portal and go to the Access Keys tab.
      • Retrieve the username and password of the Admin user and use the Basic Auth Header Generator tool or run echo printf '<username>:<password>' | base64 in a terminal to convert the credentials into a basic token.
      • Set the generated token as ACR_AUTH_TOKEN in environment variables.
    • OAuth2: - Generate bearer access token using the process described in Authenticate with an Azure Container Registry.

      • One method is to generate a bearer token using your basic authorization token, i.e.

                curl --location 'https://<yourregistry>*%3A*&service=<yourregistry>' \
        --header 'Authorization: Basic <basic_token>'
      • Set the generated token as ACR_AUTH_TOKEN in environment variables. Make sure to replace the Basic in the app-config.yaml with Bearer

  4. Enable an additional tab on the entity view page using the packages/app/src/components/catalog/EntityPage.tsx file as follows:

    import { AcrPage, isAcrAvailable } from '@janus-idp/backstage-plugin-acr';

    const serviceEntityPage = (
    // ...
    if={e => Boolean(isAcrAvailable(e))}
    <AcrPage />
  5. Annotate your entity using the following annotations:

    'azure-container-registry/repository-name': `<REPOSITORY-NAME>',
