3 - 创建容器

docker run -d 
-p 4430:443 -p 800:80 -p 220:22 
--name gitlab 
--restart unless-stopped 
-v /opt/gitlab/config:/etc/gitlab 
-v /opt/gitlab/logs:/var/log/gitlab 
-v /opt/gitlab/data:/var/opt/gitlab 
-v /etc/localtime:/etc/localtime 
gitlab/gitlab-ce

参数解释

• -d：后台运行
• -p：容器内部端口向外映射
• --name：命名容器名称
• --restart：重启策略
• -v：将容器GitLab 的配置、 日志 、数据等文件夹挂载到宿主机指定目录，便于日后升级
• -v /etc/localtime:/etc/localtime ：将容器时间和host设为同一个时区

实例

[root@h200 ~]# docker run -d -p 4430:443 -p 800:80 -p 220:22 --name gitlab --restart unless-stopped -v /opt/gitlab/config:/etc/gitlab -v /opt/gitlab/logs:/var/log/gitlab -v /opt/gitlab/data:/var/opt/gitlab -v /etc/localtime:/etc/localtime gitlab/gitlab-ce

[root@h200 ~]# 
[root@h200 ~]# docker ps

[root@h200 ~]# docker exec -i gitlab date

[root@h200 ~]#

4 - 开通防火墙端口

[root@h200 ~]# firewall-cmd --zone=public --permanent --add-port=800/tcp
success
[root@h200 ~]# firewall-cmd --zone=public --permanent --add-port=4430/tcp
success
[root@h200 ~]# firewall-cmd --zone=public --permanent --add-port=220/tcp
success
[root@h200 ~]# 
[root@h200 ~]# firewall-cmd --reload
success
[root@h200 ~]#

5 - 配置GitLab主机名

以容器方式运行gitlab，在gitlab上创建项目时，生成项目的URL访问地址是按容器ID来生成的，
需要配置gitlab.rb文件（GitLab的/etc/gitlab目录）来指定一个更加明确的固定URL访问地址。

添加如下内容并重启GitLab容器

external_url 'http://192.168.16.200:800'
gitlab_rails['gitlab_ssh_host'] = '192.168.16.200'
gitlab_rails['gitlab_shell_ssh_port'] = 220

实例

[root@h200 ~]# vim /opt/gitlab/config/gitlab.rb 
[root@h200 ~]# 
[root@h200 ~]# cat /opt/gitlab/config/gitlab.rb |grep -v "#" |grep -Ev "^$"
external_url 'http://192.168.16.200'
gitlab_rails['gitlab_ssh_host'] = '192.168.16.200'
gitlab_rails['gitlab_shell_ssh_port'] = 220
[root@h200 ~]# 
[root@h200 ~]# docker restart gitlab
gitlab
[root@h200 ~]# 
[root@h200 ~]# docker ps
CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS                             PORTS                                                             NAMES
118c5fc2cc0a        gitlab/gitlab-ce      "/assets/wrapper"        26 minutes ago      Up 14 seconds (health: starting)   0.0.0.0:220->22/tcp, 0.0.0.0:800->80/tcp, 0.0.0.0:4430->443/tcp   gitlab                                                                             loving_nash
[root@h200 ~]# 
[root@h200 ~]# docker ps 
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                    PORTS                                                             NAMES
118c5fc2cc0a        gitlab/gitlab-ce    "/assets/wrapper"   44 minutes ago      Up 17 minutes (healthy)   0.0.0.0:220->22/tcp, 0.0.0.0:800->80/tcp, 0.0.0.0:4430->443/tcp   gitlab
[root@h200 ~]#

确认project信息是否已更改

6 -  数据留存

通过-v参数挂载的主机文件在容器停止或删除后，仍然存在，可以在之后创建gitlab容器时，再次挂载。

[root@h200 ~]# docker ps
CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS                      PORTS                                                             NAMES
118c5fc2cc0a        gitlab/gitlab-ce      "/assets/wrapper"        47 minutes ago      Up 20 minutes (healthy)     0.0.0.0:220->22/tcp, 0.0.0.0:800->80/tcp, 0.0.0.0:4430->443/tcp   gitlab                                                                    loving_nash
