# Docker Remote Deployment Action

A [GitHub Action](https://github.com/marketplace/actions/docker-remote-deployment) that supports docker-compose and Docker Swarm deployments on a remote host using SSH.

The Action is adapted from work by [wshihadeh](https://github.com/wshihadeh/docker-deployment-action) and [TapTap21](https://github.com/TapTap21/docker-remote-deployment-action)

## Example

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

    ssh_public_key: ${{ secrets.SSH_PUBLIC_KEY }}
    deployment_mode: docker-swarm
    copy_stack_file: true
