Docker-compose部署gitlab的方法步骤

Docker-compose部署gitlab

1、安装Docker

安装必要工具

[root@vm_10_14_centos ~]# yum -y install yum-utils device-mapper-persistent-data lvm2

添加Docker-ce镜像源并安装

[root@vm_10_14_centos ~]# yum-config-manager --add-repo
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@vm_10_14_centos ~]# yum makecache fast
[root@vm_10_14_centos ~]# yum -y install docker-ce[root@gitlab ~]# yum makecache fast
[root@vm_10_14_centos ~]# yum -y install docker-ce
[root@vm_10_14_centos ~]# systemctl start docker
[root@vm_10_14_centos ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

添加Docker镜像加速

[root@vm_10_14_centos ~]# vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://9w1hl6qt.mirror.aliyuncs.com"]
}
[root@vm_10_14_centos ~]# systemctl daemon-reload
[root@vm_10_14_centos ~]# systemctl restart docker
[root@vm_10_14_centos ~]# rpm -qa docker
[root@vm_10_14_centos ~]# rpm -qa docker-ce
docker-ce-18.09.0-3.el7.x86_64
[root@vm_10_14_centos ~]# docker --version
Docker version 18.09.0, build 4d60db4
[root@vm_10_14_centos ~]# docker version

2、安装Docker-compose

下载Docker-compose二进制文件并添加执行权限

[root@vm_10_14_centos ~]# curl -L https://github.com/docker/compose/releases/download/1.23.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
 % Total % Received % Xferd Average Speed Time Time  Time Current
         Dload Upload Total Spent Left Speed
100 617 0 617 0  0 959  0 --:--:-- --:--:-- --:--:-- 958
100 11.2M 100 11.2M 0  0 1824k  0 0:00:06 0:00:06 --:--:-- 2422k
[root@vm_10_14_centos ~]# chmod +x /usr/local/bin/docker-compose
[root@vm_10_14_centos ~]# docker-compose --version
docker-compose version 1.23.2, build 1110ad01

3、安装Gitlab

（1）编辑docker-compose的yml文件

[root@vm_10_14_centos ~]# mkdir gitlab
[root@vm_10_14_centos ~]# cd gitlab/
[root@vm_10_14_centos gitlab]# vim docker-compose.yml 
version: '2'
services:
 gitlab:
  image: 'twang2218/gitlab-ce-zh:11.1.4'
  container_name: "gitlab"
  restart: unless-stopped
  privileged: true
  hostname: 'gitlab'
  environment:
  TZ: 'Asia/Shanghai'
  GITLAB_OMNIBUS_CONFIG: |
   external_url 'http://129.204.133.242'
   gitlab_rails['time_zone'] = 'Asia/Shanghai'
   gitlab_rails['smtp_enable'] = true
   gitlab_rails['smtp_address'] = "smtp.aliyun.com"
   gitlab_rails['smtp_port'] = 465
   gitlab_rails['smtp_user_name'] = "kimasd102419@aliyun.com" #用自己的aliyun邮箱
   gitlab_rails['smtp_password'] = "axbc1kof"
   gitlab_rails['smtp_domain'] = "aliyun.com"
   gitlab_rails['smtp_authentication'] = "login"
   gitlab_rails['smtp_enable_starttls_auto'] = true
   gitlab_rails['smtp_tls'] = true
   gitlab_rails['gitlab_email_from'] = 'kimasd102419@aliyun.com'
   gitlab_rails['gitlab_shell_ssh_port'] = 22
  ports:
  - '80:80'
  - '443:443'
  - '22:22'
  volumes:
  - /opt/gitlab/config:/etc/gitlab
  - /opt/gitlab/data:/var/opt/gitlab
  - /opt/gitlab/logs:/var/log/gitlab

（2）创建相关目录

[root@vm_10_14_centos gitlab]# mkdir /opt/gitlab/{config,data,logs} -p
[root@vm_10_14_centos gitlab]# ls -l /opt/gitlab/
total 12
drwxr-xr-x 2 root root 4096 Dec 8 11:35 config
drwxr-xr-x 2 root root 4096 Dec 8 11:35 data
drwxr-xr-x 2 root root 4096 Dec 8 11:35 logs

（3）拉取gitlab中文版镜像

[root@vm_10_14_centos gitlab]# docker pull twang2218/gitlab-ce-zh:11.1.4

Status: Downloaded newer image for twang2218/gitlab-ce-zh:11.1.4
[root@vm_10_14_centos gitlab]# docker image ls

（4）启动gitlab的容器

[root@vm_10_14_centos gitlab]# docker-compose up -d
Creating network "gitlab_default" with the default driver
Creating gitlab ... error

ERROR: for gitlab Cannot start service gitlab: b'driver failed programming external connectivity on endpoint gitlab (9308ca74b8491c556263eac9fb9b0abcb25258d9e2df5733fc4d9143d6b18dcc): Error starting userland proxy: listen tcp 0.0.0.0:22: bind: address already in use'

ERROR: for gitlab Cannot start service gitlab: b'driver failed programming external connectivity on endpoint gitlab (9308ca74b8491c556263eac9fb9b0abcb25258d9e2df5733fc4d9143d6b18dcc): Error starting userland proxy: listen tcp 0.0.0.0:22: bind: address already in use'
ERROR: Encountered errors while bringing up the project.
 
[root@vm_10_14_centos gitlab]# vim /etc/ssh/sshd_config 
[root@vm_10_14_centos gitlab]# systemctl restart sshd
[root@vm_10_14_centos gitlab]# netstat -tulnp |grep 22
tcp  0  0 0.0.0.0:60022   0.0.0.0:*    LISTEN  4044/sshd  

这里需要注意的是，由于gitlab容器需要用到22端口，不能与宿主机冲突，这里需要修改宿主机的sshd服务的监听端口

[root@vm_10_14_centos gitlab]# docker-compose ps
Name Command State Ports
------------------------------------------------------------------------------
------------------------
gitlab /assets/wrapper Up (healthy) 0.0.0.0:22->22/tcp, 0.0.0.0:443-
>443/tcp, 0.0.0.0:80->80/tcp

（5）gitlab设置开机启动

[root@vm_10_14_centos gitlab]# chmod +x /etc/rc.local
[root@vm_10_14_centos gitlab]# ls -l /etc/rc.local
lrwxrwxrwx. 1 root root 13 Jul 7 16:43 /etc/rc.local -> rc.d/rc.local
[root@vm_10_14_centos gitlab]# echo "cd /root/gitlab && docker-compose up -d" >>
/etc/rc.local
[root@gitlab gitlab]# tail -1 /etc/rc.local
cd /root/gitlab && docker-compose up -d
