由于我打算使用公用的redis，因此先建立一个redis镜像mysql
首先建立一个docker目录（如下以G盘为例）git
在docker目录下建立redis目录web
在redis目录下添加文件docker-compose.yml文件，内容为：redis
(2018年4月11日修改volumes下面的挂载volume不使用/g/docker/redis/xxx方式，在最新版docker中已不能使用，改成docker-compose.yml的相对路径./redis/conf来挂载)sql
version: '3'
services:
redis:
image: redis:4.0.8-alpine
container_name: db-redis
restart: always
ports:
- 6379:6379
networks:
- net_db
volumes:
- ./redis/config:/docker/config
- ./redis/data:/data
command: redis-server /docker/config/redis.conf
networks:
net_db:
external: true
在redis目录下添加config目录chrome
在config目录下添加redis.conf文件，内容为：docker
#redis的databases数量
databases 32
#redis密码
requirepass 123
回到redis目录，打开vscode、powershell或者cmdshell
首先建立一个network，而后执行docker-compose -d upubuntu
PS G:\docker\redis> docker network create net_db
0583088e9269e9d1e7029682f409690547ae9325b0aee795b3d76676b7409abc
PS G:\docker\redis> docker-compose up -d
Creating db-redis ... done
PS G:\docker\redis> docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b0b552dc45fa redis:4.0.8-alpine "docker-entrypoint.s…" 38 seconds ago Up 35 seconds 0.0.0.0:6379->6379/tcp db-redis
启动成功，用客户端链接测试localhost:6379@123(密码)链接正常windows
接下来开始启动Gitlab
在docker目录下建立gitlab目录
在其中建立docker-compose.yml文件，内容为：
version: '3'
services:
gitlab:
image: 'twang2218/gitlab-ce-zh:10.4.3'
container_name: gitlab-1043
restart: unless-stopped
environment:
TZ: 'Asia/Shanghai'
GITLAB_OMNIBUS_CONFIG: |
external_url 'http://gitlab-1043'
gitlab_rails['time_zone'] = 'Asia/Shanghai'
#如下为启用邮件相关设置，我用的是阿里云免费企业邮箱
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = 'smtp.mxhichina.com'
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = '个人阿里云企业邮箱帐号'
gitlab_rails['smtp_password'] = '个人阿里云企业邮箱密码'
gitlab_rails['smtp_domain'] = '个人阿里云企业邮箱域名'
gitlab_rails['smtp_authentication'] = 'plain'
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true
gitlab_rails['gitlab_email_from'] = '收到邮件时显示的发送邮箱'
user["git_user_email"] = '用户邮箱地址，跟上一条同样'
#修改sidekiq的数量，减小内存占用，默认为15，也能够不填
sidekiq['concurrency'] = 10
#使用外部redis所需设置，根据刚刚生成的redis设置修改
gitlab_rails['redis_port'] = 6379
gitlab_rails['redis_host'] = 'db-redis'
gitlab_rails['redis_password'] = '123'
gitlab_rails['redis_database'] = '1'
#由于22端口被占用，修改映射的端口号时，同时修改在Gitlab项目中的ssh地址加上端口号
gitlab_rails['gitlab_shell_ssh_port'] = 10022
ports:
- '10080:80'
- '10443:443'
- '10022:22'
networks:
- net_db
volumes:
- ./config:/etc/gitlab
- gitlab-data:/var/opt/gitlab
- ./logs:/var/log/gitlab
volumes:
gitlab-data:
external: true
networks:
net_db:
external: true
在Docker内部建立一个volume，而后执行docker-compose -d up
PS G:\docker\gitlab> docker volume create gitlab-data
gitlab-data
PS G:\docker\gitlab> docker-compose up -d
Creating gitlab-1043 ... done
PS G:\docker\gitlab> docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS
NAMES
c7cba6a06740 twang2218/gitlab-ce-zh:10.4.3 "/assets/wrapper" 29 seconds ago Up 24 seconds (health: starting) 0.0.0.0:10022->22/tcp, 0.0.0.0:10080->80/tcp, 0.0.0.0:10443->443/tcp gitlab-1043
b0b552dc45fa redis:4.0.8-alpine "docker-entrypoint.s…" 14 minutes ago Up 14 minutes 0.0.0.0:6379->6379/tcp
db-redis
等待Gitlab本身生成配置完成之后，就能够访问http://localhost:10080访问gitlab了
能够在等待时输入docker logs -f gitlab-1043跟踪gitlab的生成状态
若是须要备份出来gitlab-data的数据，能够建立一个临时的镜像方式把文件copy出来
PS G:\docker> docker run --name data -v /g/docker/backup:/backup -v gitlab-data:/data ubuntu:17.10 cp -r /data/ /backup/
cp: cannot create special file '/backup/data/postgresql/.s.PGSQL.5432': Operation not permitted
cp: cannot create special file '/backup/data/redis/redis.socket': Operation not permitted
cp: cannot create special file '/backup/data/gitlab-rails/sockets/gitlab.socket': Operation not permitted
cp: cannot create special file '/backup/data/gitlab-workhorse/socket': Operation not permitted
cp: cannot create special file '/backup/data/gitaly/gitaly.socket': Operation not permitted
PS G:\docker> docker rm data
data
上面这几个没法copy的文件就是致使不能使用volume直接挂载在windows目录下的缘由，其余文件均可以正常备份和修改
