This GitHub Action enables you to push a Docker image, built by GitHub Actions, to a remote server via SSH. It's designed to streamline the deployment process by automating the transfer of Docker images to your production or staging environments.

• Multiple Image Support: Push one or multiple Docker images.
• Flexible SSH Configuration: Use custom SSH keys, ports, and configurations to connect to your server.
• Small Transfer Footprint: Only the image layers that are not already present on the remote server are transferred.

To use the Docker SSH Push action in your workflow, add the following step:

- name: Push Docker Image via SSH
  uses: open-fringecore/docker-ssh-push@v0.1.2-beta
  with:
      images: |
          your-docker-image:latest
          myself/another-docker-image:latest
      ssh-host: ${{ secrets.SSH_HOST }}
      ssh-user: ${{ secrets.SSH_USER }}
      ssh-private-key: ${{ secrets.SSH_PRIVATE_KEY }}
      ssh-remote-public-key: ${{ secrets.SSH_REMOTE_PUBLIC_KEY }}
      # Optional inputs can be added as needed

It can be same format as files at /etc/ssh/ssh_host_*_key.pub on the remote server.

For example:

ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIOU8I9afZ8G5CYXXQxrsClkF8LRuvkA7DadQH2wjmp2D you@Server

The action is tested on ubuntu-* runners and should work on other runners as well. If you encounter any issues, please open an issue on the GitHub repository.
