启动容器

说明

• --name 启动容器名称
• --restart=always 总是在容器退出时重启
• --privileged=true 使容器拥有root权限
• -p 端口映射
• -v 目录挂载

docker run -d --name gitlab --restart=always \
--privileged=true \
-p 8443:443 -p 880:80 -p 822:22 \
-v /home/gitlab/config:/etc/gitlab \
-v /home/gitlab/logs:/var/log/gitlab \
-v /home/gitlab/data:/var/opt/gitlab gitlab/gitlab-ce

禁用 GitLab 自带 Nginx

编辑配置文件

vim /home/gitlab/config/gitlab.rb

添加如下配置，保存退出。

nginx['enable'] = false 
web_server['external_users'] = ['www-data']

执行如下命令使配置生效

docker exec gitlab gitlab-ctl reconfigure

配置外部 Nginx

参考如下文件对 nginx.conf 进行修改。

修改完成后，执行如下命令使配置生效

nginx -t;nginx -s reload

添加目录权限

chown -R www:www /home/gitlab/data/gitlab-workhorse/

汉化 GitLab（无效）

git clone https://github.com/marbleqi/gitlab-ce-zh.git #下载汉化包版本库（宿主机内执行）
cd gitlab-ce-zh #进入版本目录
git pull origin #从远端获取最新库
git branch -a #显示最新的分支清单
git checkout remotes/origin/v10.5.1-zh-patch #切换到相应版本的汉化分支目录
cd .. #返回上一级目录

docker cp gitlab-ce-zh gitlab:/opt/gitlab/embedded/service/ #将汉化文件从宿主机复制到容器中（宿主机内执行）
docker exec -it gitlab bash #进入容器（宿主机内执行）
cd /opt/gitlab/embedded/service/ #进入网页文件相关目录（容器内执行）
cp -rf gitlab-ce-zh/* gitlab-rails/ #将汉化文件覆盖原文件（容器内执行）

解决 Gitlab 占用内存大问题

编辑配置文件

vim /home/gitlab/config/gitlab.rb

修改如下配置，官方建议设置为 CPU 核心数 +1。

unicorn['worker_processes'] = 2
