Description

Merge both dev and prod Dockerfile into one and divide it into multi stages.

Steps to Test This Pull Request

Test dev stage

1. delete related containers and images

docker container rm ${USER}_pycontw_vm && docker image rm pycontw-pycontw

2. run the following command

./enter_dev_env.sh

3. start server

python manage.py runserver 0.0.0.0:8000

Test prod stage

1. create docker-compose-prod-demo.yml file

version: "3.5"
services:
  db:
    container_name: db_dev
    image: postgres:11-alpine
    environment:
      - POSTGRES_DB=pycontw2016
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=secretpostgres
    ports:
      - ${COMPOSE_DB_PORT:-5432}:5432
    networks:
        - network-2024
  web:
    build:
      context: .
      target: prod
    container_name: pycontw-2024
    hostname: pycontw-2024
    entrypoint: ""
    ports:
      - 8000:8000
    command:
      - bash
      - -c
      - |
        set -o errexit -o nounset -o pipefail
        python3 manage.py compilemessages
        python3 manage.py migrate
        python3 manage.py collectstatic --no-input

        exec uwsgi --http-socket :8000 \
          --master \
          --hook-master-start "unix_signal:15 gracefully_kill_them_all" \
          --static-map /static=assets \
          --static-map /media=media \
          --mount /prs=pycontw2016/wsgi.py \
          --manage-script-name \
          --offload-threads 2
    restart: always
    environment:
      DJANGO_SETTINGS_MODULE: pycontw2016.settings.production.pycontw2024
      SCRIPT_NAME: /prs
      SECRET_KEY: ${SECRET_KEY}
      DATABASE_URL: ${DATABASE_URL}
      EMAIL_URL: ${EMAIL_URL}
      GTM_TRACK_ID: ${GTM_TRACK_ID}
      SLACK_WEBHOOK_URL: ${SLACK_WEBHOOK_URL}

    volumes:
      - ${MEDIA_ROOT}:/usr/local/app/src/media
    networks:
        - network-2024

networks:
     network-2024:
        name: network-2024

2. run the following command

docker-compose -f ./docker-compose-prod-demo.yml up --build

3. visit http:https://localhost:8000/

More Information

1. remove ENV PATH /usr/local/bin:$PATH due to duplicate entries /usr/local/bin
2. I also remove ENV PATH /home/docker/.local/bin:$PATH to centralise where pip install packages and to align the PATH between production environment and development environment.
3. I also remove chown -R docker:nogroup "$BASE_DIR" "$APP_DIR" and use COPY --chown instead to avoid unnecessary image size increasing. references: https://garbers.co.za/2017/11/15/reduce-docker-image-size-chmod-chown/ , https://stackoverflow.com/questions/30085621/why-does-chown-increase-size-of-docker-image

It works well!
No error were found during docker build, and websites on staging are functioning. I attach docker logs here:docker_20240510.log

If no further issues are found, and staging remains stable throughout the weekend, I will merge to main branch and deploy to prod.

@SivanYeh I believe we can merge this, right?
