Can't access Homer using hom7-json-influx

[lminiero]

Hi guys,

being a docker dummy, I wanted to try to get my hands "dirty", and launch Homer using one of the available scripts. I started with hom7-json-influx, that seemed like a good place to start, but even though the docker compose process seems to start things correctly, I can't access the Homer UI. More precisely, if I open localhost:9080 with a browser, I'm presented with a login page, but inserting the credentials provided in the README nothing happens: after a while, I get an error on a JWT token not being returned, which suggests a DB error.

Looking at the docker-compose output, I see a couple of things that seem out of place and that may be the cause of the issue:

The first is the nodejs error: this might be because most nodejs installations now only install /usr/bin/node and not /usr/bin/nodejs. I thought this was tied to my local installation (which does lack a nodejs executable), but even adding a symbolic link the error remained, so it's likely a missing executable inside the image itself. Not sure if that can be the cause of the issue, though.

Another likely culprit seems to be the password authentication failed for user "homer", which seems to indeed suggest a DB error: for some reason the application can't contact Postgres at startup, which may be why the login process timeouts when I try it later on. I already tried removing the influx and postgres-data folders more than once and bring the image back up using docker-compose, but nothing changed.

Unfortunately, since everything is retrieved and deployed automatically via docker, I have no idea on how I can mess with the image to see if I can fix things myself manually. Any hint on what may be going wrong, and/or how I can fix it?

Thanks!

Hi @lminiero. Maybe you could directly jump to the 7.7 branch? https://github.com/sipcapture/homer7-docker/tree/7.7/hepop/hom7-json-influx

Don't really know if it's ready for daily use yet maybe @lmangani can give you an eta.
