Manage Docker Hub rate limits

Prevent issues from imposed rate limits

Konvoy customers can configure their cluster to authenticate with registries (such as Docker Hub), and add registries, by defining each in the ClusterConfiguration .spec.imageRegistries list in the cluster.yaml file.

For Konvoy, to add credentials for Docker Hub, set the options in your cluster.yaml as follows:

kind: ClusterConfiguration
    - server:
      username: "<username>"
      password: "<password>"
          konvoy.docker-registry-username: <username>
          konvoy.docker-registry-password: <password>

NOTE: You can use environment variables to specify `imageRegistries` values. For example, if your yaml file has `password: ${REGISTRY_PASSWORD}`, `password` is set to the `REGISTRY_PASSWORD` value in your environment.

  1. Apply the changes to your cluster. Enter the following command:

    konvoy up.
  2. Confirm the changes made to the cluster. Enter the following command to check the contents of the containerd configuration file:

    $ cat /etc/containerd/config.toml
              endpoint = [""]
                username = "<username>"
                password = "<password>"
                auth = ""
                identitytoken = ""
