I am facing to an issue with Kong, i created my service and my route exactly like the 5min quickstart of the Kong’s documentation but i only change some parameters to setup the service with my own api working on localhost:3000.
So there is my setup:
- Kong running on docker (Docker is running on the same machine than my service)
- http://localhost:3000/users which is my service always returning JSON
{“status”: “OK”}
there is what i did to create my service.
I created my service with parameters :
{
"name": "users",
"url": "http://localhost:3000",
"host": "127.0.0.1"
}
then i created the Route with body:
{
"hosts": [ "127.0.0.1"],
"methods": ["GET"],
"paths": ["/"],
"name": "users"
}
then i tried if everything is working with http://localhost:8080/users with header:
“Host:127.0.0.1”
and i got the reply:
502 Bad Gateway : An invalid response was received from the upstream
server
The docker’s Logs (this one hosting kong) :
2019/03/04 09:28:36 [error] 36#0: *63824 connect() failed (111:
Connection refused) while connecting to upstream, client: 172.18.0.1,
server: kong, request: “GET /users HTTP/1.1”, upstream:
“http://127.0.0.1:3000/users”, host: “127.0.0.1”
So we can see Kong trying to access the good endpoint ‘127.0.0.1:3000/’ but can’t access to it.
Maybe Kong trying to access is own container localhost but i don’t know, and i don’t know how to fix it, maybe you can help me!
