在 Docker 上运行的 Redis 在一段时间后关闭

Question

我有一个在 Docker 上使用 Redis 的非常简单的环境，在我将堆栈移至 Digital Ocean 之前，它曾经运行良好。我的应用程序停止工作，然后我必须重新启动它。它工作了几个小时（不到一天），然后又停止了。

当我打印出容器的日志时，这是我得到的：

我没有添加任何特殊配置来复制数据、主、从或类似的东西。这是我的作文

version: '3'
services:      
  server:
    image: server
    build: .
    ports:
     - "8091:8091"
    container_name: server
    environment:
      - NODE_ENV=production
    external_links: 
      - redis

  redis:
    image: redis:5.0.5
    ports:
      - "6379:6379"
    container_name: redis

有人知道发生了什么吗？没有发生

Answer 1

您的 Redis 可以从 Internet 上获取并且已被黑客入侵。通过删除redis服务中的ports部分来关闭端口：

    ports:
      - "6379:6379"

进一步，移除容器 docker-compose rm 并再次向上。
