Docker Registry Credentials (Optional)

Set up Docker Registry credentials for external registry users

If you use an external Docker registry (outside of Google’s own GCR or GAR) like Docker Hub, Amazon ECR, or private registries, you must configure Docker registry credentials. This step ensures that your GCP environment has the proper authentication to access images from an external registry, preventing unauthorized access or image pull failures.

This step is only needed if you are using an external non-GCR registry.

Set Docker Registry Credentials

1. In the DuploCloud Portal, navigate to Docker -> Services.

2. From the Docker list box, select Docker Credentials. The Set Docker registry Creds pane displays.

3. Enter your Docker credentials (Username, Password, and Email), and click Submit. The Docker registry credentials are passed to the Kubernetes cluster as a kubernetes.io/dockerconfigjson secret.

Add Multiple Docker Registry Credentials

Pull images from multiple Docker registries by adding multiple Docker Registry Credentials.

1. In the DuploCloud Portal, click Administrator -> Plan. The Plans page displays.

2. Select the Plan name from the NAME column.

3. Select the Config tab, and click Add. The Add Config pane displays.

4. In the Config Type list box, select DockerRegistryCreds.

5. In the Name field, enter the registry name.

6. In the Value field, enter your registry credentials.

7. Click Submit.
