Inter-app communication in 24.10 Electric Eel

Try radarr.ix-radarr-4k.svc.cluster.local. The format is {container}.ix-{app-name}.svc.cluster.local. The container name for Radarr instances is always radarr, so all you need to change is the app name to that of the second instance.

This worked thank you!

I will note just for reference that on Dragonfish and earlier the format that worked was actually the radarr-4k.ix-radarr-4k.svc.cluster.local format.

I don’t know enough about any of this to say why, just putting it out there. That was the format I pulled using HeavyScript.

You just saved my weekend!

I just resently wanted to ditch truenas as a whole because i went through the hell of the core apps years ago and ended up with custom jails and a VM eating all resources of my nas, because there was no native homeassistant deployment. So i gave the migration a try from truenas core to scale and with that came the update of homeassistant which now uses postgres instead of sqlite. So i thought i could also get rid of my influxdb and connect grafana directly to the postgres until i couldn’t.

The networking problem brought up some bad memories with truenas apps. And this google search would have been my last action before killing truenas out of my life.

So thank you very much! I can now successfully add postgres.ix-home-assistant.svc.cluster.local as a datasource in my grafana.

You should put a buymeacoffee link on your github

I made a small service that creates a Docker network and automatically attaches all containers managed by middlewared, and adds a DNS alias in the k8s-style format for each service, effectively restoring the inter-app networking functionality from Dragonfish.

This is excellent work, thank you! Within seconds I was able to install this and have my apps (from catalog and custom ones) all talk together as needed.

Thank you very much, sir! You’re a gentleman and a scholar!

As a stop-gap until this is implemented in Fangtooth

Can you confirm everything is working in Fangtooth or do you need per App IP addressing?

[tjhorner]

I can try it out in a VM when I get some time, hopefully this week. What changes should I look out for to achieve this?

[Captain_Morgan]

Since you created the request and also a very useful workaround (many thanks!), you are more expert than me.

My guess is that for new/custom apps you can connect them to special network. for standard Apps, you might need to wait for per IP addressing change on June 1.

If it doesn’t work, it would be useful to know what doesn’t and whether your workaround still works.

I was just trying to see if the problem was solved as expected.

[tjhorner]

Got it, I’ll try it out and let you know
