GitLab于Linux如何进行容器化部署 - 问答

在Linux上进行GitLab的容器化部署，可以按照以下步骤进行：

准备工作

安装Docker：确保你的Linux系统上已经安装了Docker。如果没有安装，可以参考Docker官方文档进行安装。

安装Docker Compose：Docker Compose是一个用于定义和运行多容器Docker应用程序的工具。你可以通过以下命令安装Docker Compose：

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

部署步骤

创建存储目录：

mkdir -p /opt/docker/gitlab
cd /opt/docker/gitlab

创建docker-compose.yml文件：
```
touch docker-compose.yml
```

编辑docker-compose.yml文件：在docker-compose.yml文件中添加以下内容：

version: '3'
services:
  gitlab:
    image: 'gitlab/gitlab-ce:latest'
    restart: always
    container_name: gitlab
    hostname: '192.168.1.200'
    environment:
      GITLAB_OMNIBUS_CONFIG: |
        gitlab_rails['time_zone'] = 'asia/shanghai'
      GITLAB_SSH_PORT: 22
      GITLAB_HTTP_PORT: 80
      GITLAB_外部URL: 'http://192.168.1.200'
    ports:
      - '80:80'
      - '22:22'
    volumes:
      - './config:/etc/gitlab'
      - './logs:/var/log/gitlab'
      - './data:/var/opt/gitlab'
    healthcheck:
      test: ["cmd", "/opt/gitlab/bin/gitlab-healthcheck", "--fail"]
      interval: 30s
      timeout: 10s
      retries: 5
    deploy:
      resources:
        limits:
          cpus: '4.00'
          memory: 4096m
          reservations:
            cpus: '2.00'
            memory: 2048m

请将hostname处的内容修改为你实际的主机IP地址。

启动GitLab容器：
```
docker-compose up -d
```

放行端口（如果需要）：

firewall-cmd --add-port=80/tcp --permanent
firewall-cmd --add-port=22/tcp --permanent
firewall-cmd --reload

访问GitLab管理页面：打开浏览器，访问http://192.168.1.200，初次登录需要设置账号密码。使用用户名root和你设置的密码登录。

配置HTTPS（可选）

如果你想将GitLab配置为HTTPS，可以按照以下步骤进行：

生成SSL证书：

mkdir -p conf/ssl
cd conf/ssl
openssl genrsa -out server.key 2048
openssl genrsa -out private.key 2048
openssl req -new -key private.key -out cert_req.csr -subj "/C=CN/ST=TEST/L=TEST/O=test/OU=main/CN=*.gitpool.com/emailAddress=root@localhost.com"
openssl x509 -req -days 365 -in cert_req.csr -signkey private.key -out server_cert.crt

修改docker-compose.yml文件：

version: '3'
services:
  gitlab:
    image: 'gitlab/gitlab-ce:latest'
    restart: always
    container_name: gitlab
    hostname: 'gitlab'
    environment:
      TZ: 'Asia/Shanghai'
      GITLAB_OMNIBUS_CONFIG: |
        gitlab_rails['gitlab_shell_ssh_port'] = 22
        gitlab_rails['http_port'] = 80
        gitlab_rails['https_port'] = 443
      GITLAB_外部URL: 'https://192.168.1.200'
    ports:
      - '443:443'
      - '80:80'
    volumes:
      - '/etc/localtime:/etc/localtime:ro'
      - './data:/var/opt/gitlab'
      - './logs:/var/log/gitlab'
      - './conf:/etc/gitlab'
      - './conf/ssl:/etc/gitlab/ssl'
    healthcheck:
      test: ["cmd", "/opt/gitlab/bin/gitlab-healthcheck", "--fail"]
      interval: 30s
      timeout: 10s
      retries: 5
    deploy:
      resources:
        limits:
          cpus: '4.00'
          memory: 4096m
          reservations:
            cpus: '2.00'
            memory: 2048m

修改GitLab配置文件：

vim /opt/docker/gitlab/conf/gitlab.rb

找到以下配置并修改：

nginx['enable'] = true
nginx['client_max_body_size'] = '512m'
nginx['redirect_http_to_https'] = true
nginx['redirect_http_to_https_port'] = 80
nginx['ssl_certificate'] = "/etc/gitlab/ssl/server_cert.crt"
nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/private.key"
nginx['ssl_session_cache'] = "client_sessions"

重新配置并重启GitLab：

sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart

现在，你应该可以通过https://192.168.1.200访问配置为HTTPS的GitLab管理页面。

希望这些步骤能帮助你成功在Linux上进行GitLab的容器化部署。如果有任何问题，请参考GitLab的官方文档或相关社区资源。
