Docker-compose apache guacamole卡住了

Question

我正在使用docker-compose版本1.25.0与nginx容器和guacamole + guacd容器版本1.2.0，

环境运行良好，直到2-3天一次的guacamole + guacd容器被这个日志卡住：

鳄梨调味酱：

我的应用程序接口代码让(<Response [502]>,)从鳄梨色拉酱获取令牌请求，容器被卡住，日志中没有其他移动。

在我整理好所有的东西后，一切又开始工作了。但我不明白是什么导致了这个问题，一切都很好，直到它不再工作，只有完全重启才能让它再次工作。

我怎么知道是什么引起的呢？有没有办法在容器卡住的时候让docker重启？我正在考虑将guacd和guacamole从1.2.0更新到1.3.0，我只是不明白为什么突然(在6个月的一切正常工作之后)它开始有这个bug。

Docker在8月30日左右发布了一个主要的产品和服务条款更新。这可能是你问题的根源。不要使用RDP错误堆栈，而是尝试基于oznu中修改后的瓜卡莫尔图像运行以下docker-compose.yml文件。它包括guacamole web客户端、guacd服务器和postgres数据库。容器已经在我的机器上运行了大约一个星期，没有任何问题。

version: "2"
services:
  guacamole:
    image: oznu/guacamole
    container_name: guacamole
    volumes:
      - postgres:/config
    ports:
      - 8080:8080
volumes:
  postgres:
    driver: local
