Installing Gekko using Docker: UI is unable to open a websocket connection

[edudemy]

I'm submitting a ... [x] bug report [ ] question about the decisions made in the repository

Action taken (what you did) Installing Git Master Gekko using Docker # $ docker-compose build $ docker-compose up -d

Expected result (what you hoped would happen) gekko instance running on localhost:3000.

Actual result (unexpected outcome)

Disconnected Something happened to either Gekko or the connection. Please check the terminal where Gekko is running or your network connection.

This message is shown when the UI is unable to open a websocket connection with the Gekko Server.

Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, etc)

Maybe this is something very basic, the web UI loads up in the background but the above error pops up saying the websocket is unable to connect.

Attaching Docker Logs

$ docker logs -f gekko_gekko_1

Serving Gekko UI on http://localhost:3000/

Something went wrong when trying to open your web browser. UI is running on http://localhost:3000/.

WARNING: The PORT variable is not set. Defaulting to a blank string.
ERROR: The Compose file './../../../docker-compose.yml' is invalid because:
services.gekko.ports is invalid: Invalid port ":", should be [[remote_ip:]remote_port[-remote_port]:]port[/protocol]

Any pointers on how to solve this would be helpful. I'm running docker on Mac OS X.

were you able to find a solution ? as i'm having the same issue when trying to deploy my gekko docker image to kubernetes

[viking76]

Don't use localhost prefere real IP and set a real Port, i think is "The PORT variable is not set" set it to 3000. It was not be "Serving Gekko UI on http://localhost:3000/" but Serving Gekko UI on http://IP:3000/ I have an docker who work well now :) with Environnement PORT:3000 If it doesn't work try to delete, download, make good environment IP & PORT and start, Why? : because it it wasn't good at 1st start the docker-entrypoint.sh wasn't work well after its faullty config, Solution: you can change before compose on Dockerfile
