Question

我对this set泊坞窗文件有一个非常奇怪的问题：

docker run将执行我想要的操作，而docker-compose将不会

我和Docker非常相似，因此这可能是一个相当简单的问题 - 我提前道歉！

但我无法确定我的错误

docker run -p 80:8080 -i -t lakrids_devlakrids 172.17.0.1 - - [01/Feb/2017:23:29:36 +0000] "GET / HTTP/1.1" 200 6979 "-" "curl/7.29.0"

但如果我用docker-compose启动相同的容器，我会得到

docker-compose up devlakrids Recreating devlakrids Attaching to devlakrids devlakrids | 2017/02/01 23:28:19 [emerg] 11#11: host not found in upstream "httpstat.us" in /etc/nginx/nginx.conf:21 devlakrids | nginx: [emerg] host not found in upstream "httpstat.us" in /etc/nginx/nginx.conf:21 devlakrids exited with code 1

Answer 1

两个可能的罪魁祸首：

nginx是一个有趣的野兽：如果上游在nginx已经运行时发生故障，那么nginx会继续运行。但是，如果nginx启动时无法访问上游，则后者将无法启动。要解决此问题，您可能需要在启动nginx之前向您nginx容器测试添加启动脚本，以便上游启动;
尝试明确添加links：我们遇到了这个问题，nginx泊坞窗没有看到通过compose服务名称隐式定义的其他计算机。

最后，一个真正被遗忘的选项是：您没有在您显示的文件中指定在docker引擎中启动httpstat.us服务的任何位置，因此实际上令人惊讶的是它在没有撰写的情况下适合您。

根据描述，您在合成之外运行的图像可能与您在合成中运行的图像不同，或者您有不同的卷安装。要解决您的错误，我将使用上游定义更新您的nginx.conf：

daemon off;
worker_processes 1;
events { worker_connections 1024; }
http {
   upstream httpstat.us {
       least_conn;
       server httpstat.us:80 fail_timeout=60s max_fails=2;
   }

   sendfile on;
   server {
      listen 8080;
      server_name dev.lakrids.premier-is.dk;

      location / {
         proxy_pass http://httpstat.us/;
         proxy_set_header  X-Real-IP  $remote_addr;
      }
   }
}

这就是让我的一天（我永远感谢C. Eastwood先生）:)）

nginx容器在我的设计中兼作反向代理 - 并处理443安全端 - 允许“普通”应用服务器处理业务逻辑：

# ./docker-compose.yml
version: '2'
services:
  proxy:
    build: ./shared/proxy
    networks:
    - sand
    links:
    - devlakrids:devlakrids
    ports:
    - 80:80
    - 443:443

  # sand[kassen]
  #
  devlakrids:
    build: ./sand/current/spark
    expose:
    - "4567"
    tmpfs: /tmp
    volumes:
    - ./sand/current/:/mnt/lakrids
    - ./shared/sand/:/shared
    links:
    - sandmysql
    networks:
    - sand
    - sanddb

# ./shared/proxy/services.conf

server {
        listen 80;
        listen 443 ssl http2;
        server_name dev.lakrids.xxxx.xxx;

        # Path for SSL config/key/certificate
        ssl on;
        ssl_certificate /etc/ssl/certs/nginx/xxx.crt;
        ssl_certificate_key /etc/ssl/certs/nginx/xxxx.pem;
        include /etc/nginx/includes/ssl.conf;
        add_header Strict-Transport-Security "max-age=31536000";

        location / {
                include /etc/nginx/includes/proxy.conf;
                proxy_pass http://devlakrids:4567;
        }

        access_log off;
        error_log  /var/log/nginx/error.log error;
}

# ./shared/proxy/includes/proxy.conf
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_buffering off;
proxy_request_buffering off;
proxy_http_version 1.1;
proxy_intercept_errors on;

有了这个 - 剩下要做的就是docker-compose up大体上来了;）
