Upstream Error when running via docker

gurjmatharu commented 4 years ago

Hi,

Thanks for this awesome tooling-set! Really cool. I'm running into an issue trying to launch ml-hub via docker.

Expected behaviour:

ML-Hub launches and is able to accept connections.

Steps to reproduce the issue:

From https://github.com/ml-tooling/ml-workspace#multi-user-setup

Run the following docker command:

docker run -p 8080:8080 --name mlhub -v /var/run/docker.sock:/var/run/docker.sock mltooling/ml-hub:latest

Technical details:

Hub version: latest
Docker version Docker version 19.03.5, build 633a0ea
Host Machine OS (Windows/Linux/Mac): Mac
Command used to start the hub: docker run -p 8080:8080 --name mlhub -v /var/run/docker.sock:/var/run/docker.sock mltooling/ml-hub:latest
Browser (Chrome/Firefox/Safari): Chrome

Possible Fix: N/A

Additional context:

Output from docker:

Hey @gurjmatharu,

thanks for the feedback!

Could you try the following please:

docker rm mlhub;
docker run \
    -d \
    -p 8080:8080 \
    -v /var/run/docker.sock:/var/run/docker.sock \
    mltooling/ml-hub:0.1.10

It's always best to use a dedicated version instead of latest. Further, unfortunately, the hub documentation you linked is not up-to-date, so for the newest documentation, check the mlhub page. Sorry for the inconvenience!
