gitlab runner 完成构建后部署

Question

我想使用 gitlab 运行器部署成功构建的 docker 映像，但我不确定如何使用 .gitlab-ci.yml 中的部署阶段来执行此操作。构建日志显示在构建过程中在 docker 映像上正确创建了数据库。

我在 Mac (OSX 10.11.6) 上本地使用 docker 来构建我的 docker 容器。 Gitlab 正在远程运行。我注册了一个特定的本地跑步者来处理构建。当我将更改推送到我的项目时，gitlab CI 会运行构建脚本来创建一个测试数据库。图像构建后会发生什么？我的本地计算机上没有列出已完成构建的 docker 映像。 gitlab-runner-prebuilt-x86_64 是一个准系统 linux 映像，与构建无关。

您没有在 CI 上构建任何 docker 映像。

您正在使用来自 DockerHub 的 php7 映像来执行所有作业。这包括工作deploy_job1，它试图使用docker 二进制来推送不在该容器内的图像（deploy:latest）。另外，我认为docker 二进制文件不包含在php7 图像中。

我猜你想在你的 Mac 上推送你本地构建的镜像，不是吗？在这种情况下，您需要使用另一个运行器，它的执行器应该是shell。在这种情况下，您将有 2 个运行器，一个使用 docker 运行 build_job1 作业，另一个用于推送本地构建的图像。但是有一个更好的解决方案是手动构建docker镜像，就是让GitLab CI来构建它。

所以，修改你的.gitlab-ci.yml（删除你的 cmets，添加地雷进行解释）：

# Removed global image definition

stages:
  - build
  - test
  - deploy     

variables:
  db_name: db_test
  db_schema: "db_test_schema.sql"

build_job1:
  stage: build
  # Use image ONLY in docker runner
  image: php7:latest
  script:
    - service mysql start
    - echo "create database $db_name" | mysql -u root
    - mysql -u root $db_name < $db_schema
    - mysql -u root -e "show databases; use $db_name; show tables;"
  # Run on runner with docker executor, this is ok
  tags:
    - docker

deploy_job1:
  stage: deploy
  script:
    # Build the docker image first, and then push it
    - docker build -t deploy:latest .
    - docker push deploy:latest
  # Run on runner with shell executor, set proper tag
  tags:
    - docker_builder

注册新的runner时，设置executor为shell，tag为docker_builder。我假设你已经在你的 Mac 上安装了 docker 引擎。

另一方面，这个例子毫无意义，至少对我来说是这样。 build 阶段什么都不做，因为容器是短暂的。我想你应该在 Dockerfile 上这样做。
