Question

我想使用gitlab运行器来部署成功构建的docker镜像，但我不知道如何在.gitlab-ci.yml中使用deploy阶段来执行此操作。构建日志显示在构建过程中在docker镜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运行构建脚本来创建测试数据库。它构建后的图像会发生什么？我的本地计算机上列出的已完成构建没有泊坞窗图像。 gitlab-runner-prebuilt-x86_64是一个与构建版本无关的准系统linux映像。

您未在CI上构建任何泊坞窗图片。

您正在使用DockerHub中的php7映像执行所有作业。这包括尝试使用deploy_job1二进制文件来推送不在该容器内的图像（docker）的作业deploy:latest。另外，我认为docker图像中不包含php7二进制文件。

我想你想要在Mac上推送你本地构建的图像，不是吗？在这种情况下，您需要使用另一个运行器，其执行器应为shell。在这种情况下，您将有2个跑步者，一个使用docker来运行build_job1作业，另一个使用推送本地构建的图像。但是有一个更好的解决方案，可以手动构建docker镜像，并且可以让GitLab CI构建它。

所以，修改你的.gitlab-ci.yml（删除你的评论，添加地雷作为解释）：

# 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

注册新跑步者时，请将执行者设置为shell并标记docker_builder。我想你已在Mac上安装了docker引擎。

另一方面，这个例子毫无意义，至少对我而言。 build阶段没有任何作用，因为容器是短暂的。我想你应该在Dockerfile上做到这一点。

在gitlab runner完成构建
