Docker Connector Settings Reference

This topic provides settings and permissions for the Docker Connector.

Docker registry rate limits​

For pulling Docker images from Docker repos, Harness is restricted by the limits of the Docker repo. For example, Docker Hub limits.

Docker Registries in Cloud Platforms​

The Docker Connector is platform-agnostic and can be used to connect to any Docker container registry, but Harness provides first class support for registries in AWS and GCR.

See:

Docker Registry Permissions Required​

Make sure the connected user account has the following permissions.

  • Read permission for all repositories.

The user needs access and permissions to the following:

  • List images and tags
  • Pull images

See Docker Permissions.

If you are using anonymous access to a Docker registry for a Kubernetes deployment, then imagePullSecrets should be removed from the container specification. This is standard Kubernetes behavior and not related to Harness specifically.

ID​

See Entity Identifier Reference.

Description​
