拉取镜像

1	docker pull gitlab/gitlab-runner:latest

创建挂载目录

1	mkdir -p /opt/gitlab-runner/config

启动容器

1	docker run -d --name gitlab-runner --restart always -v /opt/gitlab-runner/config:/etc/gitlab-runner -v /var/run/docker.sock:/var/run/docker.sock gitlab/gitlab-runner:latest

进入runner容器，注册到gitlab上

汇总操作命令：

docker exec -it gitlab-runner  gitlab-runner register -n \
  --url http://192.168.0.253:8090 \
  --registration-token tyXBwC8frbShS4yn3nE5 \ # token需要根据实际情况进行修改
  --tag-list=dockersock,docker \
  --description "dockersock" \
  --docker-privileged=true \
  --docker-pull-policy="if-not-present" \
  --docker-image "docker:latest" \
  --docker-volumes /var/run/docker.sock:/var/run/docker.sock \
  --docker-volumes /root/m2:/root/.m2 \
  --executor docker

分步操作命令：

进入容器

1	docker exec -it gitlab-runner /bin/bash

运行以下注册命令

1	gitlab-runner register

输入Gitlab实例的地址

1 2	Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com ) http://192.168.0.253:8090 # 端口采用默认的80，否则需要加上端口，比如 http://192.168.0.253:8090

输入token

Please enter the gitlab-ci token for this runner
tyXBwC8frbShS4yn3nE5
如何获取token
进入到项目中的设置，找到CI/CD，Runner ，图片这个token仅供途径展示

输入Runner的描述，后期可以手动修改

1 2	Please enter the gitlab-ci description for this runner [hostname] my-runner

输入与Runner关联的标签，后期可以手动修改

1 2	Please enter the gitlab-ci tags for this runner (comma separated): my-tag

输入Ruuner的执行者

1 2	Please enter the executor: ssh, docker+machine, docker-ssh+machine, kubernetes, docker, parallels, virtualbox, docker-ssh, shell: docker

如果上面执行者为docker，需要你在后续项目根部的.gitlab-ci.yml中指定docker版本

1
2
3

Please enter the Docker image (eg. ruby:2.1):
alpine:latest
通过以上命令后，就可以在gitlab中查看到了这个刚刚创建的runner

runner注册完毕之后，还需要修改一下runner的配置文件，实现runner与宿主机的数据挂载:

vim /opt/gitlab-runner/config/config.toml # 开头创建的宿主机挂载目录

check_interval = 0
