SSH to VPS from GitHub actions

SSH Key: Generate an SSH key pair if you don't have one:

ssh-keygen -t rsa -b 4096 -C "[email protected]"

Copy the public key to your VPS:

ssh-copy-id username@your_vps_ip

Can do it manually adding the public key to ~/.ssh/authorized_keys

Actions config

Add SSH Private Key to GitHub Secrets

• Go to your repository on GitHub.
• Navigate to Settings > Secrets and variables > Actions.
• Add a new secret named SSH_PRIVATE_KEY and paste the contents of your private key (id_ed25519).

    branches:
      - master  # Adjust based on your branch strategy

    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Setup SSH
        uses: webfactory/[email protected]
        with:
          ssh-private-key: ${{ secrets.SSH_PRIVATE_KEY }}

          port: 22  # Change if your SSH runs on a different port
          source: "path/to/local/files/*"  # Adjust based on your local file paths
          target: "/path/to/remote/directory/"  # Adjust to your target directory on the VPS
