Docker部署Gitlab

前置环境

docker 19.03.13

部署步骤

初始化配置文件

-- 拉取镜像
docker pull beginor/gitlab-ce:10.7.5-ce.0

-- 挂载目录 config[配置文件],logs[日志],data[数据]
mkdir -p /home/feature/docker/software/gitlab/config
mkdir -p /home/feature/docker/software/gitlab/logs
mkdir -p /home/feature/docker/software/gitlab/data

80端口部署方式（二选一）

 docker run --name=gitlab -d \
    -p 80:80 -p 443:443 -p 22:22 \
    --restart always \
    -e TZ=Asia/Shanghai \
    -m 3072m
    -v /home/feature/docker/software/gitlab/config:/etc/gitlab \
    -v /home/feature/docker/software/gitlab/logs:/var/log/gitlab \
    -v /home/feature/docker/software/gitlab/data/:/var/opt/gitlab \
    beginor/gitlab-ce:10.7.5-ce.0

非80端口需要的部署方式（二选一）

第一步：启动docker

# 先更换端口启动项目，如7001 置换为原来的80
 docker run --name=gitlab -d \
    -p 7001:7001 -p 7002:443 -p 7003:22 \
    --restart always \
    -e TZ=Asia/Shanghai \
    -m 3072m
    -v /home/feature/docker/software/gitlab/config:/etc/gitlab \
    -v /home/feature/docker/software/gitlab/logs:/var/log/gitlab \
    -v /home/feature/docker/software/gitlab/data:/var/opt/gitlab \
    beginor/gitlab-ce:10.7.5-ce.0

第二步修改 gitlab.rb文件

xxx.xxx.xxx.xxx 为外网访问IP

vim /home/feature/docker/software/gitlab/config/gitlab.rb

# 配置http协议所使用的访问地址,不加端口号默认为80
external_url 'http://xxx.xxx.xxx.xxx:7001'
# 配置ssh协议所使用的访问地址和端口
gitlab_rails['gitlab_ssh_host'] = 'xxx.xxx.xxx.xxx'
# 此端口是run时22端口映射的 7003 端口
gitlab_rails['gitlab_shell_ssh_port'] = 7003

第三步修改 gitlab.yml

vim /home/feature/docker/software/gitlab/data/gitlab-rails/etc/gitlab.yml

gitlab:
    ## Web server settings (note: host is the FQDN, do not include http://)
    host: xxx.xxx.xxx.xxx 
    port: 7001
    https: false

    # Uncommment this line below if your ssh host is different from HTTP/HTTPS one
    # (you'd obviously need to replace ssh.host_example.com with your own host).
    # Otherwise, ssh host will be set to the `host:` value above
    ssh_host: xxx.xxx.xxx.xxx

刷新配置

docker exec -it gitlab gitlab-ctl restart

遇见问题

执行 docker run gitlab的时候，提示“ WARNING: Your kernel does not support swap limit capabilities or the cgroup is not mounted. Memory limited without swap.

原因：在Ubuntu上默认是没有开启Swap限制的，这样就会导致容器的swap限制不生效
解决方案：
第一步将/etc/default/grub文件中的GRUB_CMDLINE_LINUX参数，修改为"RUB_CMDLINE_LINUX=“cgroup_enable=memory swapaccount=1”
第二步使用 sudo update-grub 更新系统的GRUB后，并重启系统文章来源地址https://www.toymoban.com/news/detail-627243.html
```
GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1
```
```
sudo update-grub
```
启动成功后访问 http://xxx.xxx.xxx.xxx:7001 失败，确认防火墙是否开启
