Step 1 – Create Demo Repo

Make a PHP demo POC repo like this:
https://github.com/deepak4566/demo-fresh-poc.git
Then add a script.sh file which will run inside the server.

---

Step 2 – Setup GCP Server

Go to Google Cloud Console and create a demo web server:
https://console.cloud.google.com/compute/instances

Login into the server and create private and public keys using:
GitHub SSH key generation guide

---

Step 3 – Add SSH Keys to GitHub

• Add the private key to GitHub repository secrets as GCP_SSH_PRIVATE_KEY.
• Add the public key to your GitHub profile settings under SSH keys.

---

Step 4 – Add GitHub Workflow

Here is a sample GitHub workflow to deploy:

name: Deploy to Google Cloud Instance

on:
  push:

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Deploy to Compute Engine Instance
        run: |
          INSTANCE_NAME="fresh-poc"
          ZONE="us-central1-b"
          SSH_USER="deepakreddyats1"
          SSH_KEY="${{ secrets.GCP_SSH_PRIVATE_KEY }}"
          DEPLOY_SCRIPT="Script.sh"

          echo "$SSH_KEY" > private_key
          chmod 600 private_key

          ssh-keygen -y -f private_key > private_key.pub
          mkdir -p ~/.ssh
          ssh-keyscan -H 34.45.123.96 >> ~/.ssh/known_hosts

          scp -i private_key $DEPLOY_SCRIPT "$SSH_USER@34.45.123.96:~/"
          ssh -i private_key "$SSH_USER@34.45.123.96" "bash ~/Script.sh"

Make sure to replace IP, zone, and usernames with your own values.

Conclusion

This SOP demonstrates automated deployment from GitHub to a web server. It significantly reduces manual deployment effort.
