How to migrate a docker compose app to CodeCatalyst on EC2 and amplify?

Hi everyone,

I migrated my frontend to Amplify and now I have issue connecting to my backend that is still on an ec2 instance due to the api connection using http and not https. I thus want to take this occasion to migrate everything to CodeCatalyst. My question is thus how to deploy an application similar to the one deployed by the git action file and docker compose file below on CodeCatalyst?

Currently I run the following GitHub actions:

name: Docker Build and Deploy to Server

on:
  push:
    branches:
      - main

env:
  VERSION_NUMBER: latest
  APP_NAME: app
  APP_NAME_API: app-api
  REMOTE_HOST: xxxx.eu-central-1.compute.amazonaws.com

jobs:
  docker_build:
    name: Docker Build
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2
      
      - name: Create Artifact Directory
        id: image-dir
        run: |
          mkdir images

      - name: Build, tag, and archive image [API]
        id: build-image-api
        run: |
          docker build -t $APP_NAME_API:$VERSION_NUMBER libs/agent
          docker save $APP_NAME_API:$VERSION_NUMBER > images/$APP_NAME_API.tar

      - name: rsync deployments
        uses: burnett01/rsync-deployments@5.2
        with:
          switches: -avzr --delete
          path: images
          remote_path: /home/ubuntu
          remote_host: ${{ env.REMOTE_HOST }}
          remote_user: ubuntu
          remote_key: ${{ secrets.STAGING_DEPLOY_KEY }}

      - name: Docker Load and Spin Up Server
        uses: appleboy/ssh-action@master
        with:
          host: ${{ env.REMOTE_HOST }}
          username: ubuntu
          key: ${{ secrets.STAGING_DEPLOY_KEY }}
          script: |
            docker load < ~/images/${{ env.APP_NAME_API }}.tar  
            docker compose down
            docker compose --env-file docker.env up -d
            rm ~/images/*
            docker system prune -f -a

And the following docker-compose with the respective env files:

version: "3"

services:
  app-api:
    container_name: app-api
    network_mode: ${NETWORK_MODE}
    build:
      context: ../agent
      dockerfile: Dockerfile
    command: ["/bin/bash", "setup.docker.sh"]
    environment:
      - PORT=8080
    ports:
      - 8080:8080
    env_file:
      - api.env
    depends_on:
      pgdb:
        condition: service_healthy
    restart: unless-stopped

  pgdb:
    container_name: pgdb
    network_mode: ${NETWORK_MODE}
    image: postgres:12
    restart: unless-stopped
    volumes:
      - type: volume
        source: pgdb-data
        target: "/var/lib/postgresql/data"
    environment:
      POSTGRES_DB: admin
      POSTGRES_USER: ${DBUSER}
      POSTGRES_PASSWORD: ${DBPASS}
    ports:
      - 5432:5432
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U ${DBUSER}"]
      interval: 30s
      timeout: 30s
      retries: 3

  pgadmin:
    container_name: pgadmin
    network_mode: ${NETWORK_MODE}
    image: dpage/pgadmin4
    environment:
      PGADMIN_DEFAULT_EMAIL: ${PGADMIN_DEFAULT_EMAIL}
      PGADMIN_DEFAULT_PASSWORD: ${PGADMIN_DEFAULT_PASSWORD}
      PGADMIN_LISTEN_ADDRESS: 0.0.0.0
      PGADMIN_LISTEN_PORT: 5050
    ports:
      - 5050:5050
    volumes:
      - type: volume
        source: pgadmin-data
        target: /root/.pgadmin
    restart: unless-stopped

volumes:
  pgdb-data:
  pgadmin-data:

Thanks in advance for the support.

Best,
