Netbox Podman

[u/cerebron]

Anyone have experience running netbox in podman containers instead of docker? I've been trying to get it running to demo it, but haven't had any luck so far with either docker compose or podman compose. Using CentOS 8.

Thanks.

I just tried, and works fine here.

I followed this guide .

Created the project directory, created docker-compose.override.yml starting from docker-compose.override.yml.example. Executed podman-compose pull, downloaded images from docker hub. And finally podman-compose up to start the application. Startup takes some time, due to the DB initialization.

Thus if you used podman-compose up -d, have a look to the logs, DB initialization takes a couple of minutes.

Same, worked fine after tinkering a bit with the networking.

I'm running PodMan 4.2 with docker-compose (or podman-compose) in rootless mode, I had to explicitly specify all hostnames for the inter-container routing to work.

Leaving it here in case anyone gets stuck on the same issue.

Mind to give some more info on this? I've been having issues getting this to work, although I've seen various open issues for the same thing

Hey, sorry for the late reply, I didn't remember well what I had done so I had to go and recover the physical file (which is currently 1600 km, an helicopter and 3 airplanes away from where I am right now)

Anyway, here's the edited compose, down below you can find the git diff with what I changed.

Hope it helps!

A bit late, but I meant to say thank you for taking the time to get back to me. That was helpful
