NEO4J + traefik proxy Issues

[siharris]

I've been using traefik to proxy an nginx docker container and all works perfectly. When i try neo4j container it doesn't work giving me a 404 page not found. I curl'd the URL and interestingly it responds with

StatusCode : 200
StatusDescription : OK
Content : {
"management" : "http://localhost/db/manage/",
"data" : "http://localhost/db/data/"
}
RawContent : HTTP/1.1 200 OK

I then ran a non-proxyed docker instance of neo4j and it works fine and also returns the same response as above , although 10 bytes larger

StatusCode : 200
StatusDescription : OK
Content : {
"management" : "http://localhost:7474/db/manage/",

I used the test docker compose example setup on the traefik site as a basis config and added the sections below :-

neo4j:
image: neo4j:2.3
labels:
- "traefik.backend=neo4j"
- "traefik.frontend.rule=PathStrip: /neo4j"
- "traefik.port=7474"
- "traefik.frontend.entryPoints=http"

nginx2:
image: nginx
labels:
- "traefik.backend=nginx2"
- "traefik.frontend.rule=PathStrip: /nginx2"
- "traefik.port=80"
- "traefix.port=443"
- "traefik.frontend.entryPoints=http"

I think its something to do with the Content Type being application/json. Have i got the config wrong or is this something anyone has encountered. Setup is on WIndows 10 running docker for WIndows.

@siharris You are using a PathStrip rule to route requests to your neo4j backend, so I guess that you try to use the URL : http://localhost/neo4j the problem is that neo4j tries to redirect you to the web console : http://localhost/browser but this URL can' be routed by Traefik.

There is may be a workaround in neo4j configuration to make him aware that it's public URL use the /neo4j prefix.

But the simplest solution is to use hostname based routing :

• replace "traefik.frontend.rule=PathStrip: /neo4j" with "traefik.frontend.rule=Host:neo4j.localhost"
• make sure that the name neo4j.localhost is resolved to your machine
• use neo4j with this URL : http://neo4j.localhost
