Repository Credentials (cluster)

This article refers to Platform v3.1.0. The current Platform version is v3.4.0.

Overview​

The Docker Credentials card at the cluster level mirrors the per-node Credentials card, but the credentials you add here are propagated to every node in the cluster automatically — every node can pull private images without you having to repeat the setup per node.

The card shows the credentials defined on the cluster, along with their status. From the card you can:

  • Add a credential by hand.
  • Add credentials in bulk from a CSV file.
  • Delete credentials one at a time or all at once.

Every change is propagated to every node in the cluster automatically.

Add a credential​

Fill in:

  • Repository — the URL of the private image registry.
  • User — the username for that registry.
  • Password — the password for the user.

Confirm. The credential is pushed to every node in the cluster within seconds and validated automatically on each one.

tip

For Docker Hub, use http://index.docker.io as the repository URL.

Summary​

The cluster-level Docker Credentials card centralises private-registry authentication for the cluster — add once, get propagated everywhere. For per-node credentials outside of a cluster, see Repository credentials.
