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。如果使用nginx，则必须绕过并直接连接代理与服务器。”但Apache setup instructions使用“ ProxyPassReverse”设置。

我认为这种不一致导致了此错误：

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

在您的情况下，8000是普通的旧http，而9000是grpc。我希望apache代理以您配置的方式为无人机ui端口（8000）工作。我将利用docker-compose的网络功能，允许服务器和代理都通过端口9000进行通话。

类似的东西：

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:

Answer 2

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表示有错误的旧版本容器正在使用端口9000和8000，从而阻止了我的新容器使用它们。

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

我仍然对此有疑问。不幸的是，在调试docker的过程中，我清除了apache服务器，并对samba做了一些操作（网络计算机看不到它们），但这完全是另一个问题。因此，我的docker-compose脚本无法完全正常运行，但不再告诉我该端口已在使用中。现在看来问题出在阿帕奇（Apache）不在服役，所以无人机无法与之对话。

drone.io apache说明是否过时？
