一、下载镜像

官方版本是：gitlab/gitlab-ce:latest，为了提升速度我们这里使用阿里云的仓库

$ docker pull registry.cn-hangzhou.aliyuncs.com/imooc/gitlab-ce:latest

二、运行GitLab容器

使用docker命令运行容器，注意修改hostname为自己喜欢的名字，-v部分挂载目录要修改为自己的目录。
端口映射这里使用的都是安全端口，如果大家的环境没有端口限制或冲突可以使用与容器同端口，如：-p 443:443 -p 80:80 -p 22:22
1. 生成启动文件 - start.sh

[root@node01 ~]$ mkdir -p i/apps/gitlab
[root@node01 ~]$ cd i/apps/gitlab/
$ cat <<EOF > start.sh
#!/bin/bash
HOST_NAME=gitlab.wanfei.com
GITLAB_DIR=`pwd`
docker stop gitlab
docker rm gitlab
docker run -d \\
    --hostname \${HOST_NAME} \\
    --restart always \\
    -p 9443:443 -p 9080:80 -p 2222:22 \\
    --name gitlab \\
    -v \${GITLAB_DIR}/config:/etc/gitlab \\
    -v \${GITLAB_DIR}/logs:/var/log/gitlab \\
    -v \${GITLAB_DIR}/data:/var/opt/gitlab \\
    registry.cn-hangzhou.aliyuncs.com/imooc/gitlab-ce:latest
EOF

2. 运行start.sh 启动gitlab

[root@node01 gitlab]$ sh start.sh
Error response from daemon: No such container: gitlab
Error: No such container: gitlab
29ffb281227a5724810e2a248e362079e48a358fa32d6574f2a30d78fee2a45e
#查看日志
docker logs -f 29

3. 配置环境

• 修改host文件，使域名可以正常解析

192.168.2.43 gitlab.wanfei.com

• 修改ssh端口（如果主机端口使用的不是22端口）

修改文件：${GITLAB_DIR}/config/gitlab.rb 找到这一行：# gitlab_rails['gitlab_shell_ssh_port'] = 22 把22修改为你的宿主机端口（这里是2222）。然后将注释去掉。

#等安装完成，第一次有点慢
[root@node01 gitlab]# ls
config  data  logs  start.sh
[root@node01 gitlab]# cd config/
[root@node01 config]# ls
gitlab.rb            ssh_host_ecdsa_key      ssh_host_ed25519_key      ssh_host_rsa_key      trusted-certs
gitlab-secrets.json  ssh_host_ecdsa_key.pub  ssh_host_ed25519_key.pub  ssh_host_rsa_key.pub
[root@node01 config]# vi gitlab.rb
#修改
# gitlab_rails['gitlab_shell_ssh_port'] = 22
gitlab_rails['gitlab_shell_ssh_port'] = 2222

• 重新启动容器

[root@node01 config]# cd ..
[root@node01 gitlab]# sh start.sh
gitlab
gitlab
10b7d408b51981fcbd353ad4e10251746bda9061f68dac5a208df1a400a74a49
[root@node01 gitlab]# docker logs -f 10

三、GitLab试用

1. 打开首页
地址：http://gitlab.wanfei.com:9080/
2. 设置管理员密码
首先根据提示输入管理员密码，这个密码是管理员用户的密码。对应的用户名是root，用于以管理员身份登录Gitlab。

• mac/linux

#先看看是不是已经有啦，如果有内容就直接copy贴过去就行啦
$ cat ~/.ssh/id_rsa.pub

#如果上一步没有这个文件 我们就创建一个，运行下面命令（邮箱改成自己的哦），一路回车就好了
$ ssh-keygen -t rsa -C "youremail@example.com"
$ cat ~/.ssh/id_rsa.pub

• window电脑

• 如果已经在本机生成了key在这里查看

  
  
  
  
• 如果没有生成，点击下面生成
  windows生成git ssh密钥

6. 测试一下
点开我们刚创建的项目，复制ssh的地址

然后查看gitlab发现代码成功提交

四. 在阿里云服务器上装了gitlab后发现服务器非常卡顿

上面不行用这个
