Docker Hub

Container registry credentials#

From version 22.3, Tower supports the configuration of credentials for container registry services. These credentials are leveraged by the Nextflow Wave container service to authenticate to private container registries. For more information on Wave containers, see here.

Docker Hub makes use of Personal Access Tokens for authentication. Note that we do not currently support Docker Hub authentication using 2FA (two-factor authentication).

To create your new Docker Hub registry credential in Tower, follow these steps:

1. Create a Personal Access Token for your user account in Docker Hub.

2. In Tower, navigate to the Credentials tab and select Add Credentials.

3. Enter a unique name in the Name field using alphanumeric characters, dashes, or underscores.

4. From the Provider drop-down list, select Container registry. The New Credentials form now displays additional fields to be completed:

5. Enter the Docker username in the User name field.

6. Enter the Personal Access Token in the Password field.

7. (Optional) Enter in the Registry server field.

8. Select Add. The new credential is now listed under the Credentials tab.

9. In order for your pipeline execution to leverage Wave containers, add wave { enabled=true } either to the Nextflow config field on the launch page, or to your nextflow.config file.
