Github Action

aizu

On Linux server

Run:

cd .ssh
ssh-keygen -t ed25519 -a 200 -C "[email protected]"
cat id_ed25519.pub >> authorized_keys

Now, copy the content of .ssh/ed25519 file into GitHub Action secret variable. (Repo > Settings > Secret & Variables > Actions > New Repository Secret)

The copied content of .ssh/ed25519 file has to start from:

-----BEGIN PRIVATE KEY-----
...... key ......
-----END PRIVATE KEY-----

Suggestion name : REMOTE_PRIVATE_KEY

Create 2 more keys & value for;

REMOTE_HOST (example: 172.0.0.1)
REMOTE_USER (example: root)

So, you will have 3 secrets.

Now, create a folder & YAML file in the repo.

File: .github/workflows/ssh-remote-execution.yml

name: Remote SSH Command

on:
  push:
    branches:
      - master

jobs:
  execute-remote-script:
    runs-on: ubuntu-latest
    steps:
    - name: Execute script on remote server
      uses: appleboy/ssh-action@master
      with:
        host: ${{ secrets.REMOTE_HOST }}
        username: ${{ secrets.REMOTE_USER }}
        key: ${{ secrets.REMOTE_PRIVATE_KEY }}
        script: |
          cd /var/www/app_location/www/source
          git reset --hard
          git pull
          npm i
          npm run build
          pm2 restart app_name

Then, commit to branch master.
