drone.io apache 指令是否已过时？

Question

Drone.io 0.8 的 release notes 说“请注意 grpc 使用 http/2 并且不能通过反向代理（即 nginx）进行路由。如果您使用的是 nginx，则必须绕过代理并直接与服务器。”但Apache setup instructions 使用“ProxyPassReverse”设置。

我认为这种不一致导致了这个错误：

user@host:~/drone $ docker-compose up
Recreating drone_drone-server_1

在您的情况下，8000 是普通的旧 http，而 9000 是 grpc。我希望 apache 代理能够按照您配置的方式为无人机 ui 端口 (8000) 工作。我会利用 docker-compose 的网络功能来允许服务器和代理都通过端口 9000 进行通信。

类似这样的：

version: '2'

services:
  drone-server:
    image: drone/drone:0.8

    ports:
      - 8000:8000
      - 9000:9000
    volumes:
      - /var/lib/drone:/var/lib/drone/
    restart: always
    environment:
      - DRONE_OPEN=true
      - DRONE_ADMIN=gogs
      - DRONE_HOST=http://<hostname>:8000
      - DRONE_GOGS=true
      - DRONE_GOGS_URL=http://<hostname>:3000
      - DRONE_SECRET=${DRONE_SECRET}
      - DRONE_GOGS_SKIP_VERIFY=true
    networks
      - drone

  drone-agent:
    image: drone/agent:0.8

    command: agent
    restart: always
    depends_on:
      - drone-server
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - DRONE_SERVER=drone-server:9000
      - DRONE_SECRET=${DRONE_SECRET}
    networks
      - drone     

   networks:
     drone:

此特定问题的原因是 docker 容器尝试使用的端口已在使用中。这是因为设置了restart: "always"，according to the docs 意味着有错误的旧版本容器正在使用端口 9000 和 8000，从而阻止我的新容器使用它们。

我通过 removing all old images and containers 修复了这个问题，然后运行 ​​sudo docker-compose up。

我仍然有这个问题。不幸的是，在调试 docker 的过程中，我以某种方式清除了我的 apache 服务器和 samba（网络计算机看不到它们），但这完全是一个不同的问题。因此，我的 docker-compose 脚本不能完全工作，但它不再告诉我端口已在使用中。现在看来问题是 Apache 不为 gogs 服务，所以无人机无法与它交谈。
