我自己用的云服务器只有4g内存，在部署了gitlab后，发现机器卡主不动了，一看内存直接来到了3.4左右。浏览器访问Gitlab页面，也是缓慢卡顿异常。遂发觉Gitlab本身带有的各种服务是很消耗内存的，于是在网上找寻如何有效解决gitlab消耗内存过大的问题。发现了，上面参考链接中的文章。下面是我的最佳实践：

准备Docker环境

推荐教程：https://segmentfault.com/a/11...

部署Gitlab（基于Docker）

任意目录下创建一个docker-compose.yml文件，内容如下：

# yml的格式缩进可能被打乱了，需要自己进行一下格式化（必要！）
version: "3"


services:
  gitlab:
    restart: always
    # 设置镜像源
    image: gitlab/gitlab-ce:14.0.5-ce.0
    container_name: gitlab
    hostname: gitlab.soulteary.com
    ports:  
      # 映射gitlab https访问端口到主机9443
      - "9443:443"
      # 映射gitlab http访问端口到主机9080
      - "9080:80"
      # 映射gitlab ssh访问端口到主机9022
      - "9022:22"
    volumes:
      # 挂载gitlab配置文件目录到主机/usr/local/gitlab/config
      - /usr/local/gitlab/config:/etc/gitlab
      # 挂载gitlab日志文件目录到主机/usr/local/gitlab/logs
      - /usr/local/gitlab/logs:/var/log/gitlab
      # 挂载gitlab数据目录到主机/usr/local/gitlab/data
      - /usr/local/gitlab/data:/var/opt/gitlab
    environment:
      # 设置时区
      TZ: Asia/Shanghai
      GITLAB_OMNIBUS_CONFIG: |
        external_url 'http://gitlab.soulteary.com'
        gitlab_rails['time_zone'] = 'Asia/Shanghai'

        # 关闭电子邮件相关功能
        gitlab_rails['smtp_enable'] = false
        gitlab_rails['gitlab_email_enabled'] = false
        gitlab_rails['incoming_email_enabled'] = false

        # Terraform
        gitlab_rails['terraform_state_enabled'] = false

        # Usage Statistics
        gitlab_rails['usage_ping_enabled'] = false
        gitlab_rails['sentry_enabled'] = false
        grafana['reporting_enabled'] = false

        # 关闭容器仓库功能
        gitlab_rails['gitlab_default_projects_features_container_registry'] = false
        gitlab_rails['registry_enabled'] = false
        registry['enable'] = false
        registry_nginx['enable'] = false

        # 包仓库
        gitlab_rails['packages_enabled'] = false
        gitlab_rails['dependency_proxy_enabled'] = false

        # GitLab KAS
        gitlab_kas['enable'] = false
        gitlab_rails['gitlab_kas_enabled'] = false

        # Mattermost
        mattermost['enable'] = false
        mattermost_nginx['enable'] = false

        # Kerberos
        gitlab_rails['kerberos_enabled'] = false
        sentinel['enable'] = false

        # GitLab Pages
        gitlab_pages['enable'] = false
        pages_nginx['enable'] = false

        # 禁用 PUMA 集群模式
        puma['worker_processes'] = 0
        puma['min_threads'] = 1
        puma['max_threads'] = 2

        # 降低后台守护进程并发数
        sidekiq['max_concurrency'] = 5

        gitlab_ci['gitlab_ci_all_broken_builds'] = false
        gitlab_ci['gitlab_ci_add_pusher'] = false

        # 关闭监控
        prometheus_monitoring['enable'] = false
        alertmanager['enable'] = false
        node_exporter['enable'] = false
        redis_exporter['enable'] = false
        postgres_exporter['enable'] = false
        pgbouncer_exporter['enable'] = false
        gitlab_exporter['enable'] = false
        grafana['enable'] = false
        sidekiq['metrics_enabled'] = false

在docker-compose.yml文件同目录下面，执行下面命令，启动gitlab
```
docker-compose up -d
```
如果遇到docker-compose不可用的提示，请参考下面文章，进行docker-compose的安装。https://segmentfault.com/a/11...
执行命令查看，gitlab是否启动
```
docker ps
```
浏览器访问http://主机ip:9080

默认账号为root，初始密码在/etc/gitlab/initial_root_password中查看

gitlab部署安装成功！
