This seems to be an issue when using a remote redis server, if using local server so far I havn't seen this crash.

I'm using a remote redis server without any problems

chetan commented 1 year ago

@hongkongkiwi I am using it successfully with a remote redis server as well, so I don't think that directly is the issue here.

According to the logs you provided, the crash is within traefik's docker config parsing. It seems to be panicking when looking for the container port binding. Can you provide your full compose file? Is anything else changing in the service config when you switch to using the remote redis server for traefik-kop?

chetan commented 1 year ago

@hongkongkiwi give the latest version a try and see if the upgraded traefik lib fixes your issue. If not, please provide more details on your config.

chetan commented 1 year ago

This actually looks similar to #20 and should now be fixed in v0.13. Let me know if you still see an issue.
