Question

我正在使用Kong来公开Konga - 这是一个用于Kong管理界面的UI。

我正在使用docker stack和以下dockerfile运行它：

(gdb) bt 1
#0  Handler::send (this=0x2ba2b10, src=..., to=..., newMessage=true) at main.cpp:138

我使用命令

secrets:
  webservices_hostname:
    external: true
  webservices_cert:
    external: true
  webservices_key:
    external: true

services:

#Create a new empty database for kong to use
# postgress used instead of cassendra as I haven't been able to find a healthcheck command for cassendra
  kong-database:

#The next section starts a UI for kong called konga. 
#We only need a ui for development experimentation and can be removed if no UI is required
# when it is running it can be accessed on port 1337
  konga:
    image: pantsel/konga
    deploy:
      restart_policy:
        condition: on-failure
    ports:
     - 1337:1337

#Configure kong to forward requests to flaskapp
  kong-addapis-konga:
    image: byrnedo/alpine-curl
    deploy:
      restart_policy:
        condition: on-failure
    command: "-i -X POST \
                --url http://kong:8001/apis/ \
                --data 'name=flaskapp' \
                --data 'uris=/flaskapp' \
                --data 'upstream_url=http://flaskapp:80'
                --data 'https_only=false'
             "

如果我访问主持人：1337 Konga将正常工作。我可以去连接，它连接到kong admin api没有问题（http://kong:8001）

但是，如果我访问https://host:443/konga或http://host:80/konga，它会毫无问题地进入konga，但是当我尝试让konga连接到kong时，我收到错误：

“哦快攻！无法连接到http://kong:8001”

为什么通过Kong访问Konga会导致这种行为？我认为如何连接到Konga并不重要 - 一旦到达那里，使用直接暴露的端口或通过Kong应该没有区别。

任何见解？

Answer 1

您应该创建一个网络并将其连接到kong。在konga配置中使用创建的网络。

docker network create my-net

docker network connect my-net kong

docker run --rm --network my-net -p 8080:8080 pantsel/konga start --kong-url http://kong:8001

Answer 2

我也遇到了同样的错误，在路线的末尾添加了一个斜杠解决了该问题。而不是http://host:80/konga致电http://host:80/konga/ 因此，该路线将代替/ konga，/ konda /

用Kong揭露Konga
