Linux

Hello! Thanks to everyone who helped me yesterday, but I could not solve the issue. I however identified the problem. I opened a new thread to better focus on the real problem.

I just set up a debian server, installed docker from the official repo and then immich using docker compose. When I run docker compose up -d (after a few seconds) my server loses internet connectivity: it can access local addresses (I can ssh into it) but cannot access the internet: ping linux.org fails.

if I put down immich (docker compose down) it starts working again. the issue is probably that docker is creating a network bridge that conflicts with the host.

After searching the web, I tried to create /etc/docker/daemon.json like this:

{
  "bip": "172.18.0.1/24",
  "default-address-pools": [
    {"base": "172.19.0.0/16", "size": 24}
  ]
}

after the changes systemctl restart docker, then wait 10 seconds for everything to restart correctly.
I tried different configurations of addresses here (every stackoverflow answer gave different values, so I tried all of them), but none of them worked. I don't know how to get which values to put here (if this is actually the solution)

a strange behavior I observed is that running ip route flush 0/0 temporary solves the problem, until the restart of docker, and Immich works normally (at least the "normal" behavior, I don't know if this affects some functionalities)

Any tips? This is my really first experience in self hosting and I have to admit it, I thought it would have been easier :P

In case you'll need it, here's the output of ip addr show:

EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm
