GitHub Action for Docker Login

The GitHub Action for Docker Login wraps the Docker CLI's docker login, allowing for Actions to log into Docker.

Because $HOME is persisted across Actions, the docker login command will save this information into $HOME/.docker/config.json, allowing other Actions to push, pull or otherwise modify images.

Usage

There are two required Secrets to be set:

  • DOCKER_USERNAME - this is the username used to log in to your Docker registry.
  • DOCKER_PASSWORD - this is the password used to log in to your Docker registry.

An example of logging into Docker Hub would look like this:

action "Docker Login" {
  uses = "actions/docker/login@master"
  secrets = ["DOCKER_USERNAME", "DOCKER_PASSWORD"]
}

In addition, if you're logging into a registry that's not Docker Hub, you can add a secret at DOCKER_REGISTRY_URL to point to a different registry.
