Implement Automatic EC2 Deployment on Main Branch Updates

[SverreNystad]

The Cogito Backend needs to have a CI/CD pipeline to make sure everything works and to automatically deploy changes. The application is hosted on an AWS EC2 instance and the codebase is stored on GitHub. I want to automate the deployment process so that any new commits pushed to the main branch automatically trigger an update on the EC2 instance.

Acceptance Criteria:

• Run all tests
• Automatically deploy changes to main branch
• Document process of creating keys on EC2 #24
• Update dependencies
• Show status of CI/CD Add badge of CI status #25

@sandviklee I need you to set secrete EC2_SSH_PRIVATE_KEY of the SSH key, i also need EC2_HOST name and EC2_USERNAME for the CD pipeline

name: Deploy to EC2
on:
  push:
    branches: [ main ]
jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout code
      uses: actions/checkout@v2

    - name: Setup SSH
      run: |
        mkdir -p ~/.ssh
        echo "${{ secrets.EC2_SSH_PRIVATE_KEY }}" > ~/.ssh/id_rsa
        chmod 600 ~/.ssh/id_rsa
        ssh-keyscan -H ${{ secrets.EC2_HOST }} >> ~/.ssh/known_hosts

    - name: Deploy to EC2
      env:
        EC2_HOST: ${{ secrets.EC2_HOST }}
        EC2_USERNAME: ${{ secrets.EC2_USERNAME }}
      run: |
        ssh -o StrictHostKeyChecking=no $EC2_USERNAME@$EC2_HOST 'bash -s' < ./deploy_to_ec2.sh

As we dockerize the container the process of automatically updating production on commits on the main branch will be easier #22

[SverreNystad]

For using Portianer we need to things:

• Portainer with HTTPS.
  • NGINX proxy manager can do it, and it pretty simple

[SverreNystad]

Portainer.io has an automatic update feature so it can update the server from github repo. It also have good support for stacks of containers making it much easier to connect all the depolyed systems to the backend without using ssh.

[SverreNystad]

This option seems better for security and scalability according Eduard

[SverreNystad]

As the EC2 instance does not have space for portainer or much more any new projects of moderate size. Portainer can not be taken in use. We need to find a way to get more storage.
