之前在本地部署了Docker +Jenkins + Gitlab，因为博客服务器在香港，直接传输不方便，还通过成都的腾讯云服务器+ Aliyun Code进行转发，完整的过程参考[腾讯云][阿里云]网站迁移小结

现在打算直接在云服务器上部署Jenkins + Gitlab，这样的构建逻辑更加直接，能够进一步压缩博客部署过程。Let's go !!!

整体流程

在本地均通过Docker方式部署Jenkins和Gitlab，所以Jenkins相关的数据保存在Docker Volume中，Gitlab相关数据保存在本地。整体实现流程如下：

  1. 将本地Jenkins和Gitlab数据打包到云服务器并解压
  2. 下载Jenkins和Gitlab镜像并启动容器
  3. 注册SSL证书，配置Https连接
  4. 设置腾讯云安全组，开放端口

对于Gitlab来说，其内置了Nginx，所以提供了相关的SSL配置参数，直接配置即可；而对于Jenkins，通过Nginx反向代理的方式设置SSL连接

Gitlab

数据迁移

打包本地数据

1
$ tar zcvf /srv/gitlab gitlab.tar.gz

上传到云服务器

1
$ scp gitlab.tar.gz ubuntu@xxx.xxx.xxx:/home/ubuntu

解压回原位置

1
$ tar zxvf gitlab.tar.gz /srv/

容器服务

下载镜像

1
$ docker pull gitlab/gitlab-ce:latest

Jenkins

数据迁移

备份和还原卷操作，参考[docker volume]创建和管理卷

容器服务

下载镜像

1
$ docker pull jenkins/jenkins:latest

容器部署

通过docker-compose方式编排容器Jenkins、Gitlab和Nginx

SSL

在阿里云下载免费的SSL证书

Gitlab

在gitlab.rb配置文件中保存相关的Nginx配置参数

结合在Nginx或Tengine服务器上安装证书，完整的配置参数如下：

unicorn['listen'] = 'localhost'
unicorn['port'] = 8999

nginx['listen_port'] = 7010 # Https监听端口
nginx['enable'] = true
nginx['ssl_certificate'] = "/etc/gitlab/ssl/gitlab.pem"     # SSL证书配置
nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/gitlab.key"

nginx['ssl_prefer_server_ciphers'] = "on"
nginx['ssl_protocols'] = "TLSv1 TLSv1.1 TLSv1.2"

  • 开放了两个端口用于Https和SSH连接
  • ssl_ciphers具体配置参数需要参考相关文档

Jenkins+Nginx

对于Docker Jenkins本身而言，不需要其他的设置，开放8080端口即可；其Https设置通过Docker Nginx完成

其配置文件如下：

$ cat jenkins.conf 
server {
    listen 7700 ssl;   # 指定端口号
    server_name xxx.xxx.xxx; # 指定域名

    ssl_certificate cert/jenkins.pem;   #将domain name.pem替换成您证书的文件名。
    ssl_certificate_key cert/jenkins.key;   #将domain name.key替换成您证书的密钥文件名。
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;

        proxy_set_header X-Rea $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Nginx-Proxy true;
        proxy_pass http://xxx.xxx.xxx:7070; # 可以使用内网地址转发到jenkins
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}
  • 设置Nginx发布的端口
  • 配置相关SSL参数
  • 通过内网地址转发到jenkins

docker-compose

使用了两个docker-compose.yml，一个用于启动Jenkins + Gitlab，另一个用于启动Nginx

安全组

最后还需要去腾讯云服务器的安全组中开放相应的端口号

博客部署

之前因为备案的关系，将博客服务器迁到香港；又因为墙的关系，在本地编译完成后，将文件上传到Aliyun Code，然后通过腾讯云服务器发送提醒消息给博客服务器，博客服务器再从远程仓库中下载相应的文件，完成更新

现在因为部署在了云服务器上，所以完成后可以直接传输提醒消息给博客服务器了

问题

Jenkins

Gitlab
