Docker安装gitlab

1. 安装docker

2. 安装firewalld

3. firewalld开启宿主机端口

   firewall-cmd --permanent --zone=public --add-port=22/tcp
   firewall-cmd --permanent --zone=public --add-port=80/tcp
   firewall-cmd --permanent --zone=public --add-port=443/tcp
   firewall-cmd --reload
   firewall-cmd --list-ports
   

4. 拉取gitlab镜像

   docker pull gitlab/gitlab-ce
   

5. 创建外部挂载目录

   mkdir /data
   mkdir /data/gitlab
   mkdir /data/gitlab/cnf
   mkdir /data/gitlab/log
   mkdir /data/gitlab/opt
   

6. 通过gitlab镜像启动一个容器

   docker run -dit \
   -p 22:22 -p 80:80 -p 443:443 \
   -v /data/gitlab/cnf:/etc/gitlab \
   -v /data/gitlab/log:/var/log/gitlab \
   -v /data/gitlab/opt:/var/opt/gitlab \
   --restart always --name gitlab \
   gitlab/gitlab-ce
   

7. 修改配置文件

   vim /data/gitlab/cnf/gitlab.rb
   
   external_url                            'http://宿主机局域网IP:80'
   nginx['listen_port']                  = 80
   
   gitlab_rails['gitlab_ssh_host']       = '宿主机局域网IP'
   gitlab_rails['gitlab_shell_ssh_port'] = 22
   
   unicorn['worker_processes']           = 2
   unicorn['worker_memory_limit_min']    = '200 * 1 << 20'
   unicorn['worker_memory_limit_max']    = '300 * 1 << 20'
   
   sidekiq['concurrency']                = 5
   
   postgresql['shared_buffers']          = '128MB'
   
   ESC
   :wq
   

8. 重载配置

   # 方法1
   docker restart gitlab
   # 方法2
   docker exec -it gitlab bash
   gitlab-ctl reconfigure
