Docker Registry

Overview

For your cluster, besides the default image sources, you can additionally specify one or several Docker Registry image repositories. You need to:

1. In Kublr, create credentials for the Docker Registry repository.

2. Attach this credentials information to your cluster.

Overrides

Docker registry(s) attached to a cluster may be used to override the default data sources.

• Override default should be specified if you want to use one of your attached Docker repositories for installing Kublr “system” components:

  • All Docker Registries for the components of Kubernetes
  • Docker Registries used by Kublr features (such as Ingress, Logging, Monitoring, KCP)

  NOTE Additional detailed Override default customization can be performed via a cluster specification. See details in System docker images customization

• Also, the following default repositories can be overridden:

  • Override docker.io
  • Override gcr.io
  • Override k8s.gcr.io
  • Override quay.io
  • Override elastic.co
