A GitHub Action that enables you to publish your app as a Docker stack to a remote Docker swarm.

Below is a brief example on how the action can be used:

- name: Deploy to swarm
  uses: sagebind/docker-swarm-deploy-action@v2
  with:
    remote_host: ssh://user@myswarm.com
    ssh_private_key: ${{ secrets.DOCKER_SSH_PRIVATE_KEY }}
    ssh_public_key: ${{ secrets.DOCKER_SSH_PUBLIC_KEY }}
    args: stack deploy --compose-file stack.yaml coolapp

If you are deploying any private Docker images, you can use the Docker Login action to first log in to your private registry, and then provide the --with-registry-auth flag to docker stack deploy to use the logged in credentials during deployment.

Below are all of the supported inputs. Some inputs used to authenticate with your swarm should be kept private, and should be supplied as secrets for security.

Arguments to pass to the docker command after connecting to the remote swarm.

Specifies how to connect to your swarm with a Docker host to connect to, using the same syntax as the Docker --host command line flag. This must be a manager node in your swarm for most operations to work.

When connecting to Docker over SSH, this must contain the SSH public key of the server for verification. Optional.

When connecting to Docker over SSH, this must contain the SSH private key to use to connect. Optional.
