Gitlab ci docker部署步骤

#事先安装好docker，下载地址：https://docs.docker.com/
#拉取gitlab-runner镜像
docker pull gitlab/gitlab-runner

#在shell里运行下面的命令，注意一下volume映射
#-v $HOME/gitlab-runner-volume/config:/etc/gitlab-runner \这一行的#\这一行的 $HOME/gitlab-runner-volume/config $HOME可以改成任意本地目录，之后会用到
# -v /var/run/docker.sock:/var/run/docker.sock \ 这一行的/var/run/docker.sock在win下可能有问题，需要找一下docker的安装位置
docker run -d \
  --name gitlab-runner \
  --restart always \
  -v $HOME/gitlab-runner-volume/config:/etc/gitlab-runner \
  -v /var/run/docker.sock:/var/run/docker.sock \
  gitlab/gitlab-runner:latest

#如果需要更新镜像，可以走这一步，否则跳过即可
docker pull gitlab/gitlab-runner:latest
docker stop gitlab-runner && docker rm gitlab-runner

docker run -d \
  --name gitlab-runner \
  --restart always \
  -v $HOME/gitlab-runner-volume/config:/etc/gitlab-runner \
  -v /var/run/docker.sock:/var/run/docker.sock \
  gitlab/gitlab-runner:latest

# 注册gitlab-runner 参考https://docs.gitlab.com/runner/register/
docker run --rm -t -i -v $HOME/gitlab-runner/config:/etc/gitlab-runner gitlab/gitlab-runner register

这时候打开你的gitlab

#上一步之后，会有一堆问题回答
Runtime platform                                    arch=amd64 os=linux pid=7 revision=4c96e5ad version=12.9.0

Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):
#上图3的网址
Please enter the gitlab-ci token for this runner:
#上图4的地址
Please enter the gitlab-ci description for this runner:
[3a594927a932]: vue typescript template
Please enter the gitlab-ci tags for this runner (comma separated):
#自己定义的标签，比如test,dev
Registering runner... succeeded                     runner=aPsdGq2A
Please enter the executor: docker-ssh, parallels, ssh, virtualbox, custom, docker, shell, docker+machine, docker-ssh+machine, kubernetes:
#写 docker
Please enter the default Docker image (e.g. ruby:2.6):
#写 alpine:latest
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!

回到你的gitlab，你就能看到下面的东西

# 运行下面的命令查看是否有问题
docker logs gitlab-runner

如果看到下面的错误，就证明docker没有生成config.toml，需要手动从之前定义的$HOME下找到config.toml复制到docker里

ERROR: Failed to load config stat /etc/gitlab-runner/config.toml: no such file or directory  builds=0
#或者下面的
ERROR: Failed to load config stat /etc/gitlab-runner/config.toml: no such file or directory  builds=0
ERROR: Failed to load config stat /etc/gitlab-runner/config.toml: no such file or directory  builds=0
ERROR: Failed to load config stat /etc/gitlab-runner/config.toml: no such file or directory  builds=0
ERROR: Failed to load config stat /etc/gitlab-runner/config.toml: no such file or directory  builds=0
ERROR: Failed to load config stat /etc/gitlab-runner/config.toml: no such file or directory  builds=0

解决步骤：

docker ps -a
#看到类似下面这样的，复制CONTAINER ID
#CONTAINER ID        IMAGE                         COMMAND                  CREATED             STATUS                      PORTS                      NAMES
c324fdf55c20        bfb85bb1e211                  "gitlab-runner-helpe…"   24 minutes ago      Exited (0) 24 minutes ago                              runner

#接着下面的走
docker exec -it 刚才复制的containerid /bin/sh
cd /etc/gitlab-runner
touch config.toml
vi config.toml
然后就是把本地的config.toml贴进去进行

再执行

#

Configuration loaded                                builds=0
Checking for jobs... received                       job=872 repo_url=https://gitlab.jingle.cn/websh/ff_event_vue_template.git runner=ejiRy6v7

WARNING: Failed to parse "X-GitLab-Trace-Update-Interval" header  error=strconv.Atoi: parsing "": invalid syntax header-value= job=872 runner=ejiRy6v7

然后我们在项目的根目录创建一个.gitlab-ci.yml

test_job_1:
    tags:
        - dev
    script:
        - echo Hello world

再push上去的时候就能看到成功了
