前提:安装docker
apt-get install docker-ce
设置runner
docker run -d --name gitlab-runner --restart always \
-v /srv/gitlab-runner/config:/etc/gitlab-runner \
-v /var/run/docker.sock:/var/run/docker.sock \
gitlab/gitlab-runner:latest
注册 runner
docker run --rm -t -i -v /srv/gitlab-runner/config:/etc/gitlab-runner gitlab/gitlab-runner register
* Enter your GitLab instance URL:
* Enter the token you obtained to register the Runner:
* Enter a description for the Runner, you can change this later in GitLab’s UI:
* Enter the tags associated with the Runner, you can change this later in GitLab’s UI:
* Enter the Runner executor: docker
* If you chose Docker as your executor, you’ll be asked for the default image to be used for projects that do not define one in .gitlab-ci.yml: alpine:latest
坑一：
run job时报错 docker executor Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
解决方法：编辑 /srv/gitlab-runner/config/config.toml 添加
volumes = ["/var/run/docker.sock:/var/run/docker.sock"]
坑二：
有些问题会使用cache保存临时文件，最终config.toml 文件最好如下：
concurrent = 20
check_interval = 0
[session_server]
session_timeout = 1800
[[runners]]
name = "runner-name"
url = "https://xxxxx/"
token = "xxxxxxx"
executor = "docker"
limit = 0
[runners.docker]
tls_verify = false
image = "alpine:latest"
privileged = false
disable_entrypoint_overwrite = false
oom_kill_disable = false
disable_cache = false
cache_dir="/srv/gitlab-runner/cache"
volumes = ["/var/run/docker.sock:/var/run/docker.sock","/srv/gitlab-runner/cache:/cache"]
shm_size = 0
[runners.cache]
[runners.cache.s3]
[runners.cache.gcs]
坑三：
有些项目在ci cd 的yaml文件中没有使用tags制定runner，导致有些项目无法找到runner
解决方法是在gitlab runner的配置页面中开启如下选项：
