docker中运行jenkins

##/bin/bash

docker run \
  --rm \
  --name jenkins-tutorials \
  -u root \
  -p 17780:8080 \
  -v jenkins-data:/var/jenkins_home \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v "$HOME":/home \
  jenkinsci/blueocean

##nginx

    location = / {
        error_page 588 = @wordpress;
        #如果有preview参数，则返回wordpress页面
        if ($arg_preview) {
            return 588;
        }
        add_header Cache-Control "no-store";
        add_header Pragma "No-cache";
        expires -1;
        etag off;
        root /data/pentaq-weui-wap/dist;
        try_files $uri $uri/ /index.html;
    }

    location @wordpress {
        root /data/var/www/trunk/app/news;
        try_files $uri $uri/ /index.php?$args;
    }

先启动备用服务，再停主服务，然后更新主服务代码，最后启动主服务关闭备用服务。

达成服务无缝更新。

##nginx

    location / {
        error_page 502 = @backup;
        proxy_pass http://127.0.0.1:4000;
        proxy_redirect off;
        proxy_set_header X-Forwarded-For             $proxy_add_x_forwarded_for; 
    }
    location @backup {
        proxy_pass http://127.0.0.1:5000;
        proxy_redirect off;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

gitlab打包了nginx, redis, postgresql, sidekiq 和 unicorn 服务。
也因此在安装gitlab的机器上你不能再独立安装nginx，你可以直接使用gitlab提供的nginx。
