Github action deploy dotnet app to a single droplet

How would I go about creating a github action to deploy a dotnet app to an existing droplet - without docker?

If that’s not possible, can I SSH into the droplet using a pwd and running a command inside of it?

Basically I want to either get the DLLs from github onto the droplet, or alternatively SSH into the droplet and run a script that pulls the source from git, and builds the app on the droplet itself

There are a number of GitHub Actions that exist for working with SHH and SCP. Here’s an example using appleboy/ssh-action and appleboy/scp-action

name: Deploy

on: [push]


    runs-on: ubuntu-latest

    - uses: actions/checkout@v1

    - name: Copy file via scp
      uses: appleboy/scp-action@master
        HOST: ${{ secrets.HOST }}
        USERNAME: ${{ secrets.USERNAME }}
        PORT: ${{ secrets.PORT }}
        KEY: ${{ secrets.SSHKEY }}
        source: "."
        target: "/opt/app"

    - name: Executing remote  command
      uses: appleboy/ssh-action@master
        host: ${{ secrets.HOST }}
        USERNAME: ${{ secrets.USERNAME }}
        PORT: ${{ secrets.PORT }}
        KEY: ${{ secrets.SSHKEY }}
        script: cat /opt/app/

This copies the git repo to /opt/app on the remote machine. Then, just as an example, it runs a remote command cat /opt/app/

A couple things to note:

  • It expects the SSH private key, the Droplet’s IP address, the port being used for SSH (e.g. 22), and the username (e.g. root) to be configured as GitHub secrets.
  • I would strongly recommend creating an SSH key specifically for this action/repo rather than re-using an existing one.

Check out the README files for the specific actions for more info.
