Bitbucket Server Authentication Provider

The Backstage core-plugin-api package comes with a Bitbucket Server authentication provider that can authenticate users using Bitbucket Server. This does NOT work with Bitbucket Cloud.

To add Bitbucket Server authentication, you must create an outgoing application link. Follow the steps described in the Bitbucket Server documentation to create one.

Configuration

The provider configuration can then be added to your app-config.yaml under the root auth configuration:

auth:
environment: development
providers:
bitbucketServer:
development:
host: bitbucket.org
clientId: ${AUTH_BITBUCKET_SERVER_CLIENT_ID}
clientSecret: ${AUTH_BITBUCKET_SERVER_CLIENT_SECRET}

The Bitbucket Server provider is a structure with two configuration keys:

  • clientId: The client ID that was generated by Bitbucket, e.g. b0f868455c15dcdff5c5fb5d173ae684.
  • clientSecret: The client secret tied to the generated client ID.

Adding the provider to the Backstage frontend

To add the provider to the frontend, add the bitbucketServerAuthApi reference and SignInPage component as shown in Adding the provider to the sign-in page.

Using Bitbucket Server for sign-in

In order to use the Bitbucket Server provider for sign-in, you must configure it with a signIn.resolver. See the Sign-In Resolver documentation for more details on how this is done. Note that for the Bitbucket Server provider, you'll want to use bitbucketServer as the provider ID, and providers.bitbucketServer.create for the provider factory.

The @backstage/plugin-auth-backend plugin also comes with a built-in resolver that can be used if desired. The emailMatchingUserEntityProfileEmail identifies users by matching their Bitbucket Server email address to the email address of User entities in the catalog. Note that you must populate your catalog with matching entities or users will not be able to sign in with this resolver.
