Hello,

Thanks so much for this and the documentation. I'm trying to setup it up running it in a server in our lab. Nevertheless I'm having two issues:

1) When I run the next warning appears:

In any case when I try to access to the IP that I defined in the .env as the HOST it turns back an ERR_CONECTION_REFUSED.

Any idea of what could be wrong? I generated TLS certificates and place it correctly. Thanks in advance!

Hi,

This error is strange:

reverse-proxy    | 2019/10/21 15:09:22 command traefik error: field not found, node: statistics

have you modified docker-compose.yml?

[caviri]

Yes, I modified it minimally. Changing the path where my certificates are:

      - /private/etc/certs:/etc/certs

I clone again the repo and the same error appears.

Maybe a noob question but I'm not familiarised with traefik, can I use my actual IP in HOST?

# The server where this JupyterHub server is hosted
HOST=XX.XX.XX.31

[defeo]

Yes, I modified it minimally. Changing the path where my certificates are:

      - /private/etc/certs:/etc/certs

I don't think it is related to this.

Maybe a noob question but I'm not familiarised with traefik, can I use my actual IP in HOST?

# The server where this JupyterHub server is hosted
HOST=XX.XX.XX.31

Yes. That means you will type your IP address in the browser address bar. Again, it doesn't seem related to this.

Oh, wait, stupid me!

The traefik version is not pinned in docker-compose.yml! There is a known issue with Traefik 2.0, see #9. The quick solution is to pin down traefik to some 1.x version, like this:

    image: traefik:1.7

The long term solution is to update this configuration to Traefik 2.0. I shall look into that at some point.

Yes! Now it works! Thanks so much for your help!
