建议虚拟机内存2G以上
搜索镜像
docker search gitlab
下载镜像文件
docker pull docker.io/gitlab/gitlab-ce
注意：一定要配置阿里云的加速镜像
创建GitLab 的配置 (etc) 、 日志 (log) 、数据 (data) 放到容器之外， 便于日后升级， 因此请先准备这三个目录。
mkdir -p /mnt/gitlab/etc
mkdir -p /mnt/gitlab/log
mkdir -p /mnt/gitlab/data
创建容器之前，我们先关闭下防火墙，重启docker服务
systemctl stop firewalld.service
firewall-cmd --state
systemctl daemon-reload
systemctl stop firewalld.service
运行GitLab容器
docker run \--detach \--publish 2222:22 \--publish 8090:80 \--publish 8443:443 \--hostname 192.168.56.3 \-v /mnt/gitlab/etc:/etc/gitlab \-v /mnt/gitlab/log:/var/log/gitlab \-v /mnt/gitlab/data:/var/opt/gitla \-v /etc/localtime:/etc/localtime:ro \--name gitlab \--restart always \--privileged=truegitlab/gitlab-ce:latest
运行成功之后，将挂载文件同步到容器外面
修改/mnt/gitlab/etc/gitlab.rb
把external_url改成部署机器的域名或者IP地址
vi /mnt/gitlab/etc/gitlab.rb
external_url 'http://192.168.56.3'
按 i 进行编辑，编辑好了按Esc，:wq 进行保存
修改/mnt/gitlab/data/gitlab-rails/etc/gitlab.yml
vi /mnt/gitlab/data/gitlab-rails/etc/gitlab.yml
找到关键字 * ## Web server settings *
按斜杠进行搜索
/Web server settings
我们进到目录再看一下挂载文件是否同步到外面来了
[root@localhost ~]# cd /mnt/gitlab/etc/[root@localhost etc]# 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
这个时候我们把容器停止再删除，然后重启服务
[root@localhost ~]# docker stop 3f3d49ac7888aaf51d51761c27f92e4bf1b465f76b1a58f3428637b9c3ffd9b7
3f3d49ac7888aaf51d51761c27f92e4bf1b465f76b1a58f3428637b9c3ffd9b7
[root@localhost ~]# docker rm 3f3d49ac7888aaf51d51761c27f92e4bf1b465f76b1a58f3428637b9c3ffd9b7
3f3d49ac7888aaf51d51761c27f92e4bf1b465f76b1a58f3428637b9c3ffd9b7
[root@localhost ~]# systemctl restart docker
[root@localhost ~]#
再来重新创建容器
docker run \
--detach \
--publish 2222:22 \
--publish 8090:80 \
--publish 8443:443 \
--hostname 192.168.56.3 \
-v /mnt/gitlab/etc:/etc/gitlab \
-v /mnt/gitlab/log:/var/log/gitlab \
-v /mnt/gitlab/data:/var/opt/gitla \
-v /etc/localtime:/etc/localtime:ro \
--name gitlab \
--restart always \
--privileged=true gitlab/gitlab-ce:latest
这个时候我们来查一下，看一下容器有没有分配ip地址，有的话表示创建容器成功了。
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
d07898b3749d gitlab/gitlab-ce "/assets/wrapper" About a minute ago Up Less than a second (health: starting) 22/tcp, 0.0.0.0:8090->80/tcp, 0.0.0.0:8443->443/tcp gitlab
f264e5f1be41 sonatype/nexus3 "sh -c ${SONATYPE_DI…" 2 hours ago Up 2 hours 0.0.0.0:8081->8081/tcp nexus
[root@localhost ~]# docker inspect d07898b3749d
访问一下ip地址
[root@localhost ~]# curl 172.17.0.3:80
curl: (7) Failed connect to 172.17.0.3:80; Connection refused
拒绝连接，说明启动没有那么快，还需要一些时间
关闭防火墙，查看下状态，这个时候防火墙已经关闭了。
[root@localhost ~]# systemctl stop firewalld.service
[root@localhost ~]# firewall-cmd --state
not running
[root@localhost ~]#
查看了下容器状态，发现gitlab一直是重启状态
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUSPORTS NAMES
d07898b3749d gitlab/gitlab-ce:latest "/assets/wrapper" 19 minutes ago Restarting (1) 1 second ago gitlab
查看日志
sudo docker logs gitlab
错误就不在这里演示了，通过谷歌解决了我的问题，
解决好之后重启下服务跟gitlab
重新验证，好了
等个几分钟，重新刷新下页面
docker安装gitlab命令
docker run \
--detach \
--publish 2222:22 \
--publish 8890:8890 \
--publish 8443:8443 \
--hostname 192.168.224.129:8890 \
-v /mnt/gitlab/etc:/etc/gitlab \
-v /mnt/gitlab/log:/var/log/gitlab \
-v /mnt/gitlab/data:/var/opt/gitla \
-v /etc/localtime:/etc/localtime:ro \
--name gitlab \
--restart always \
--privileged=true gitlab/gitlab-ce:latest
修改相关的配置
vi /mnt/gitlab/etc/gitlab.rb
// 修改如下语句
external_url 'http://192.168.2.102:82'
# https需要下面这句
# nginx['redirect_http_to_https_port'] = 82
nginx['listen_port'] = 82//http对外映射的端口
# 配置2222端口
gitlab_rails['gitlab_shell_ssh_port'] = 2222//配置ssh对外的端口
gitlab_rails['gitlab_ssh_host'] = '192.168.1.92' //ssh的地址
