Redirect Behavior Unexpected Using Digital Ocean with Caddy

Description

For my web app, I want to be able to create a reverse proxy and place all of Hasura behind api instead of the root of my domain (since that’s where my app is served from). When I followed the docs, I couldn’t get it to work from /api.

Recreation Steps

My Caddy config

my-domain.com {
    proxy /api graphql-engine:8080 {
        websocket
    }
}

Result {"path":"$","error":"resource does not exist","code":"not-found"}

After talking in the chat, all you have to do is add without /api after websocket leaving you this:

my-domain.com {
    proxy /api graphql-engine:8080 {
        websocket
        without /api
    }
}

This should give you access to the console at my-domain.com/api/console. However, if you go to my-domain.com/api, it redirects you to my-domain.com/console. If you add a trailing slash (my-domain.com/api), it redirects as expected.

@marionschleifer Seems the task have been assigned multiple times to someone different but no updates ?

It seems this issue also affect Kubernetes when using an Ingress Controller and specifying we want Hasura on a specific path :

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: ingress
spec:
  rules:
  - host: example.com
    http:
      paths:
      - path: /custom
        backend:
          serviceName: hasura
          servicePort: 8080

example.com/custom leads to {"path":"$","error":"resource does not exist","code":"not-found"}

I think it’s overall in all cases we want Hasura on someting different from root /, that the issue happens.

Here is the error output of Hasura :

{
   "type": "http-log",
   "timestamp": "2020-07-20T21:57:04.445+0000",
   "level": "error",
   "detail": {
      "operation": {
         "error": {
            "path": "$",
            "error": "resource does not exist",
            "code": "not-found"
         },
         "request_id": "a4544567-b2db-4b6f-bc70-82dd1ee7b31d",
         "response_size": 65,
         "raw_query": ""
      },
      "http_info": {
         "status": 404,
         "http_version": "HTTP/1.1",
         "url": "/custom",
         "ip": "X.X.X.X",
         "method": "GET",
         "content_encoding": null
      }
   }
}

Dunno about caddy but in nginx ingress we have to use regex for path re-writes

sample yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: testops
  labels:
    name: testops
  annotations:
    nginx.ingress.kubernetes.io/use-regex: "true"
    nginx.ingress.kubernetes.io/rewrite-target: "/$1"
    kubernetes.io/ingress.class: "nginx"
spec:
  rules:
  - host: testops.com
    http:
      paths:
      - pathType: Prefix
        path: /address/(.+)
        backend:
          service:
            name: graphql-engine
            port: 
              number: 9000
