通过docker-compose安装gitlab（docker容器安装git）

编写docker-compose.yml，然后启动即可。

web:
 image: 'gitlab/gitlab-ce:latest'
 restart: always
 hostname: 'gitlab.local.com'
 environment:
 GITLAB_OMNIBUS_CONFIG: |
 external_url 'http://gitlab.local.com:9090'
 gitlab_rails['gitlab_shell_ssh_port'] = 2224
 ports:
 - '9090:9090'
 - '2224:22'
 volumes:
 - './gitlab/config:/etc/gitlab'
 - './gitlab/logs:/var/log/gitlab'
 - './gitlab/data:/var/opt/gitlab'

同目录下需要创建目录"gitlab"，主要的配置文件在"./gitlab/config/gitlab.rb"
