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.

For Quay repositories, we recommend using robot accounts for authentication. Once set up with appropriate permissions, add the robot account's credentials to Tower using these steps:

1. Navigate to the Credentials tab and select Add Credentials.

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

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

4. Enter the robot account username (in the format namespace+accountname, i.e. mycompany+deploy) in the User name field.

5. Enter the robot account access token (found by selecting the robot account in your Quay admin panel) in the Password field.

6. Enter your registry hostname in the Registry server field.

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

8. 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.
