Docker-compose部署gitlab的方法步骤

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

									client:

									 version:   18.09.0

									 api version:  1.39

									 go version:  go1.10.4

									 git commit:  4d60db4

									 built:    wed nov 7 00:48:22 2018

									 os/arch:   linux/amd64

									 experimental:  false

									server: docker engine - community

									 engine:

									 version:   18.09.0

									 api version:  1.39 (minimum version 1.12)

									 go version:  go1.10.4

									 git commit:  4d60db4

									 built:   wed nov 7 00:19:08 2018

									 os/arch:   linux/amd64

									 experimental:  false

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

									11.1.4: pulling from twang2218/gitlab-ce-zh

									8ee29e426c26: pull complete 

									6e83b260b73b: pull complete 

									e26b65fd1143: pull complete 

									40dca07f8222: pull complete 

									b420ae9e10b3: pull complete 

									a218309dd589: pull complete 

									5c60fd7ba0ce: pull complete 

									659c2144b5a3: pull complete 

									8289bbac0d0e: pull complete 

									31bbd150e8a7: pull complete 

									9114e78243fa: pull complete 

									0b97fa2153bc: pull complete 

									308c7e15be6a: pull complete 

									b7f31b8e487d: pull complete 

									cbbb6dec5000: pull complete 

									0241c9ad6a16: pull complete 

									7fa6f0b53edd: pull complete 

									1c2861e152b2: pull complete 

									0536f3466f66: pull complete 

									digest: sha256:3c2372e3285e6d6933ddebb5ee3ae0c4bbf7cb235084e54d33d7f0ddf4813c4a

									status: downloaded newer image for twang2218/gitlab-ce-zh:11.1.4

									[root@vm_10_14_centos gitlab]# docker image ls

									repository    tag     image id   created    size

									twang2218/gitlab-ce-zh 11.1.4    1935cc9f8798  4 months ago  1.61gb

（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
