<div class="thread-body"><p>因为我打算使用公用的redis，所以先创建一个redis镜像</p>

首先创建一个docker目录（以下以G盘为例）

在docker目录下创建redis目录

在redis目录下添加文件docker-compose.yml文件，内容为：

(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，改为docker-compose.yml的相对路径./redis/conf来挂载)

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

在config目录下添加redis.conf文件，内容为：

#redis的databases数量
databases 32
#redis密码
requirepass 123

回到redis目录，打开vscode、powershell或者cmd

首先创建一个network，然后执行docker-compose -d up

PS G:docker
edis> docker network create net_db
0583088e9269e9d1e7029682f409690547ae9325b0aee795b3d76676b7409abc
PS G:docker
edis> docker-compose up -d
Creating db-redis ... done
PS G:docker
edis> 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，用客户端连接测试localhost:6379@123(密码)连接正常

接下来开始启动Gitlab

在docker目录下创建gitlab目录

在其中创建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'
        #以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'] = '我的阿里云企业邮箱账号'
        gitlab_rails['smtp_password'] = '我的阿里云企业邮箱密码'
        gitlab_rails['smtp_domain'] = '我的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，跟上一条一样'
        #修改sidekiq的数量，减少内存占用，默认为15，也可以不填
        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'
        #因为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内部创建一个volume，然后执行docker-compose -d up

PS G:dockergitlab> docker volume create gitlab-data
gitlab-data
PS G:dockergitlab> docker-compose up -d
Creating gitlab-1043 ... done
PS G:dockergitlab> 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自己生成配置完成以后，就可以访问http://localhost:10080访问gitlab了

可以在等待时输入docker logs -f gitlab-1043跟踪gitlab的生成状态

如果需要备份出来gitlab-data的数据，可以创建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

上面这几个无法copy的文件就是导致不能使用volume直接挂载在windows目录下的原因，其他文件都可以正常备份和修改

mysql也可以用同样的方式挂载在Docker的volume中

先创建一个mysql-data volume

PS G:docker> docker volume create mysql-data
mysql-data

然后创建一个mysql

(2018年4月11日修改volumes挂载方式/g/docker/mysql/xxxx为./mysql/xxx的方式，因最新版docker已不支持/g/的绝对路径表达方式，改为./的相对路径【以docker-compose.yml的相对路径】)

version: '3'
services:
  db:
    image: mysql/mysql-server:5.7.21
    container_name: db-mysql
    restart: always
    command: mysqld --character-set-server=utf8 --collation-server=utf8_general_ci
    ports:
      - 3306:3306
    networks:
      - net_db
    environment:
      MYSQL_ROOT_PASSWORD: pwd123456
    volumes:
      - ./mysql/mysql-init:/docker-entrypoint-initdb.d
      - mysql-data:/var/lib/mysql
volumes:
  mysql-data:
    external: true
networks:
  net_db:
    external: true

同样只要不手动删除mysql-data这个volume，数据就不会丢失
