Docker-compose 安装Gitlab和Gitrunner

安装

docker-compose.yaml

version: '3.5'
services:
  gitlab:
    image: gitlab/gitlab-ce:latest
    hostname: gitlab host
    restart: always
    environment:
      GITLAB_OMNIBUS_CONFIG: |
        gitlab_rails['gitlab_shell_ssh_port'] = 22
    ports:
      - "8000:80" # 网页端端口
      - "8822:22" # ssh端口
    volumes:
      - ./config/gitlab:/etc/gitlab
      - ./data/gitlab:/var/opt/gitlab
      - ./logs:/var/log/gitlab
    networks:
      - gitlab
  gitlab-runner:
    image: gitlab/gitlab-runner:alpine
    restart: always
    depends_on:
      - gitlab
    privileged: true # 使用root权限
    volumes:
      - ./config/gitlab-runner:/etc/gitlab-runner
      - /var/run/docker.sock:/var/run/docker.sock # windows上宿主机docker.sock路径://var/run/docker.sock      linux上宿主机docker.sock路径:/var/run/docker.sock 
    networks:
      - gitlab

目录结构如下：

└── logs

解决 ERROR:Docker Got permission denied while trying to connect to the Docker daemon socket at unix://

1. 给权限

   chmod 666 /var/run/docker.sock

2. 把当前用户加入docker组

   sudo usermod -aG docker $USER

3. 修改docker服务配置/usr/lib/systemd/system/docker.service

   将原有的注释
   ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
   新加代码
   ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375

4. 重启docker服务

   systemctl restart docker
