Gitlab CI 部署 Docker Python 项目

最近在公司搭建了一个新版的 gitlab，用到了新的 gitlab docker runner。

配置后端项目自动部署时踩了很多坑。特别 runner 在 docker in docker 中，需要单独挂载一个目录来存放源码。

最终还是用 Shell Executor 完成构建，Docker Executor 也一样。

看到 https://gitlab.com/gitlab-org/gitlab-ce/issues/41227 有所启发。

附上配置文件：

.gitlab-ci.yml:

image:
  name: docker/compose:1.24.1 # update tag to whatever version you want to use.
  entrypoint: ["/bin/sh", "-c"]

variables:
  DOCKER_DRIVER: overlay
  SHARED_PATH: /builds/$CI_PROJECT_PATH

services:
  - docker:dind

stages:
  - build

before_script: # 定义在 job 执行之前的执行脚本
  - echo "hello gitlab ci"
  - docker info
  - docker-compose --version

job_dev:
  only:
    - dev
  stage: build
  script:
    - pwd
    - ls -al
    - mv -f docker-compose-ci.yml docker-compose.yml
    - cat "$CONFIG_INI" > "$(pwd)/app/config/config.ini"
    - mkdir -p ${SHARED_PATH}
    - cp -r ./* ${SHARED_PATH}
    - docker-compose build
    - docker-compose up --remove-orphans --no-deps -d

docker-compose-ci.yml:

version: '3'
services:
  web:
    build:
      context: .
      dockerfile: docker/python/Dockerfile
    image: 'tianji-api:0.1.0'
    ports:
      - '5048:6000'
    volumes:
      - /builds/tianji/web-api:/code/:rw
    environment:
    - BOILERPLATE_ENV=dev  # dev
  scheduler:
    build:
      context: .
      dockerfile: docker/APScheduler/Dockerfile
    image: 'tianji-api-ap-scheduler:0.1.0'
    volumes:
      - /builds/tianji/web-api:/code/:rw
