Default compose file:
docker-compose.ymlversion: '3.1' services: drupal: image: bretfisher/custom-drupal:latest postgres: image: postgres:9.6 -
Override:
docker-compose.override.yml-
當執行
docker-compose up會自動吃到這支docker-compose.override.yml上面的 default compose file 是展示基本架構 -
這隻會直接取代
docker-compose.yml‵ 裡面的內容
version: '3.1' services: drupal: build: . ports: - "8080:80" volumes: - drupal-modules:/var/www/html/modules - drupal-profiles:/var/www/html/profiles - drupal-sites:/var/www/html/sites - ./themes:/var/www/html/themes postgres: environment: - POSTGRES_PASSWORD_FILE=/run/secrets/psql-pw secrets: - psql-pw volumes: - drupal-data:/var/lib/postgresql/data volumes: drupal-data: drupal-modules: drupal-profiles: drupal-sites: drupal-themes: secrets: psql-pw: file: psql-fake-password.txt-
看到這邊是不是很想知道，上面
build: .的 Dockerfile 長什麼樣子阿～ -
Dockerfile
FROM drupal:8.6 RUN apt-get update && apt-get install -y git \ && rm -rf /var/lib/apt/lists/* # this next part was corrected in 2018 to be more clear on how you'd typically # customize your own theme. first you need to clone the theme into this repo # with something like downloading the lastest theme for bootstrap # https://www.drupal.org/project/bootstrap and extract into themes dir on host. # then you'll COPY it into image here: WORKDIR /var/www/html/core COPY ./themes ./themes WORKDIR /var/www/html

test:
docker-compose.test.ymlversion: '3.1' services: drupal: image: custom-drupal build: . ports: - "80:80" postgres: environment: - POSTGRES_PASSWORD_FILE=/run/secrets/psql-pw secrets: - psql-pw volumes: # NOTE: this might be sample data you host in your CI server # so you can do integration testing with sample data # this may not work on Docker for Windows/Mac due to bind-mounting # database data across OS's, which doesn't always work # in those cases you should use named volumes - ./sample-data:/var/lib/postgresql/data secrets: psql-pw: file: psql-fake-password.txt -
production:
docker-compose.prod.ymlversion: '3.1' services: drupal: ports: - "80:80" volumes: - drupal-modules:/var/www/html/modules - drupal-profiles:/var/www/html/profiles - drupal-sites:/var/www/html/sites - drupal-themes:/var/www/html/themes postgres: environment: - POSTGRES_PASSWORD_FILE=/run/secrets/psql-pw secrets: - psql-pw volumes: - drupal-data:/var/lib/postgresql/data volumes: drupal-data: drupal-modules: drupal-profiles: drupal-sites: drupal-themes: secrets: psql-pw: external: true
CI Solution: 7:00
docker-compose -f docker-compose.yml -f docker-compose.test.yml up -d
CI Production Config: 7:45
-
docker-compose -f docker-compose.yml -f docker-compose.prod.yml config --help-
Validate and view the Compose file. Usage: config [options] Options: --resolve-image-digests Pin image tags to digests. -q, --quiet Only validate the configuration, don't print anything. --services Print the service names, one per line. --volumes Print the volume names, one per line. --hash="*" Print the service config hash, one per line. Set "service1,service2" for a list of specified services or use the wildcard symbol to display all services
