使用docker部署服务到gitlab, 原本以为只是做个代码库, DevOps要使用jenkins或者walle做, 结果😂... 
就这么入了gitlab-cli && gitlab-runner的坑, 爬了两天才爬出来, 仅以此篇祭奠自己的血泪.

安装docker

> 略

安装docker-compose

> 略

docker-compose 部署gitlab

dockerfile && docker-compose

可直接引用laradock的gitlab部分, 自带gitlab-cli. 本来可以仅仅使用gitlab的代码管理部分就可以了, 不过我发现了devops部分, 那就折腾起来.

docker-compose 部署gitlab-runner

docker-compose部分

RUNNER

runner:
  image: gitlab/gitlab-runner
  restart: always
  container_name: gitlab-runner
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock
    - ./gitlab-runner/config:/etc/gitlab-runner

`

docker-compose up -d runner

gitlab-runnerの注册

按照官方文档的指示, 有三种

• shell执行
• docker in docker执行
• docker套接字执行

我们来一一分解

shell执行

服务器配置注册信息

 docker exec -it gitlab-runner gitlab-runner register -n \
   --url https://gitlab.com/ \
   --registration-token REGISTRATION_TOKEN \
   --executor shell \
   --tag-list "tag" \
   --description "My Runner"

搭配的命令

 sudo usermod -aG docker gitlab-runner
 sudo -u gitlab-runner -H docker info

搭配的.gitlab-ci.yml配置(需要放到项目根目录)

 before_script:
   - docker info

 build_image:
   script:
     - docker build -t my-docker-image .
     - docker run my-docker-image /script/to/run/tests

失败

使用docker-in-docker执行器

服务器配置注册信息

 sudo gitlab-runner register -n \
   --url https://gitlab.com/ \
   --registration-token REGISTRATION_TOKEN \
   --executor docker \
   --description "My Docker Runner" \
   --docker-image "docker:stable" \
   --tag-list "tag" \
   --docker-privileged

搭配的.gitlab-ci.yml配置(需要放到项目根目录)

 image: docker:stable

 variables:
   # When using dind service we need to instruct docker, to talk with the
   # daemon started inside of the service. The daemon is available with
   # a network connection instead of the default /var/run/docker.sock socket.
   #
   # The 'docker' hostname is the alias of the service container as described at
   # https://docs.gitlab.com/ee/ci/docker/using_docker_images.html#accessing-the-services
   #
   # Note that if you're using the Kubernetes executor, the variable should be set to
   # tcp://localhost:2375/ because of how the Kubernetes executor connects services
   # to the job container
   # DOCKER_HOST: tcp://localhost:2375/
   #
   # For non-Kubernetes executors, we use tcp://docker:2375/
   DOCKER_HOST: tcp://docker:2375/
   # When using dind, it's wise to use the overlayfs driver for
   # improved performance.
   DOCKER_DRIVER: overlay2

 services:
   - docker:dind

 before_script:
   - docker info

 build:
   stage: build
   script:
     - docker build -t my-docker-image .
     - docker run my-docker-image /script/to/run/tests

失败

使用Docker套接字绑定

服务器配置注册信息

docker exec -it gitlab-runner gitlab-runner register \
           --non-interactive \
           --executor "docker" \
           --docker-image tico/docker \
           --docker-privileged \
           --docker-volumes /var/run/docker.sock:/var/run/docker.sock \
           --docker-volumes /data/wwwroot:/var/www \
           --url "http://gitcode.com:8989/" \
           --registration-token "REGISTRATION_TOKEN" \
           --description "docker-runner-web002" \
           --tag-list "docker-runner-web002" \
           --run-untagged="true" \
           --locked="false" \
           --access-level="not_protected"

注: 注意tag必须是唯一的, 多台机器公用一个, 会随机在某一台机器执行, 而不会全部执行.

搭配的.gitlab-ci.yml配置(需要放到项目根目录)

 image: docker:stable

 before_script:
   - docker info

 build:
   stage: build
   script:
     - docker build -t my-docker-image .
     - docker run my-docker-image /script/to/run/tests

成功

以上是整个项目配置的流程, 三种方式我都尝试了, 最终通过第三种方式实现.
