drone.io apache 说明过时了吗?

Question

Drone.io 0.8的发行说明说："请注意，grpc使用http/2，不能通过反向代理(即nginx(路由。如果您使用的是nginx，则必须绕过代理并将其直接连接到服务器"，但是Apache设置说明使用"ProxyPassReverse"设置。

我相信这种不一致导致了这个错误：

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

在你的例子中，8000是普通的http，9000是grpc。我希望 apache 代理能够以您配置的方式适用于无人机 ui 端口 (8000(。我将利用 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。

像这样：

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}

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restart: "always"根据文档，这意味着有错误的旧版本的容器正在使用端口 9000 和 8000，从而阻止我的新容器使用它们。

我通过删除所有旧图像和容器，然后运行sudodocker-compose up来解决此问题。

我仍然对此有问题。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 脚本无法完全工作，但它不再告诉我该端口已被使用。现在看来，问题是Apache没有提供gogs，所以无人机无法与它交谈。
