postgresql - 使用一个docker-compose.yml启动两个Wiki js容器，并通过traefik分离数据库(postgres)

Question

我正在尝试通过traefik启动两个具有不同数据库的wikijs容器。我没有启动容器的问题。我可以在子域上启动traefik，甚至可以在不同的子域上启动两个wiki。我的问题如下:每次启动wikijs容器时，我总是以某种方式使用相同的数据库，但我不知道如何更改它。
目的是让我有一些客户希望为其文档提供单独的Wiki。所以我想启动尽可能多的wikijs容器，但最好通过一个docker-compose.yml文件启动。
有人可以告诉我，我做错了吗？谢谢=)
这是我的traefik.toml文件:

defaultEntryPoints = ["http", "https"]

[entryPoints]
  [entryPoints.http]
    address = ":80"
      [entryPoints.http.redirect]
        entryPoint = "https"
  [entryPoints.https]
    address = ":443"
      [entryPoints.https.tls]
  [entryPoints.dashboard]
    address = ":8080"
    [entryPoints.dashboard.auth]
      [entryPoints.dashboard.auth.basic]
        users = ["admin:$apr1$Ld55R9Cl$/8W5BCc.J/Qtg9Xtpk4lq0"]

[api]
entrypoint="dashboard"

[acme]
email = "email@domain.com" 
storage = "acme.json"
entryPoint = "https"
onHostRule = true
  [acme.httpChallenge]

这是我的docker-compose.yml文件:

Answer 1

这两个数据库都在同一网络上:

networks:
      - internal

并在同一端口上侦听:

DB_PORT: 5432

因此，将每个数据库放入自己的网络中，然后将该网络添加到Wiki服务中，或者更改其中一个正在侦听的端口。
