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

    So I got it up and running in 10 minutes just by copy/pasting the docker-compose.yaml and .env files. So their configuration files are working flawlessly.

    Either you have a router misconfiguration or a docker network misconfiguration. Either way If I were you I would first start without duckdns.org domain name and without to much complex network configuration. Start slow and build up to more complex configurations.

    1. Leave your router defaults network configuration, without any open ports.
    2. See if your spare laptop server has internet access when everything is defaulted (if not that’s the first thing to solve)
      • Check if your networks configuration is in the inet 172.17.0.1/16 brd 172.17.255.255 range (dockers default bridge network)
      • Default routes on your laptop
      • DHCP or manual

    The important part is to make your laptop have internet access without changing to much, the default DHCP works great !

    1. Fresh docker installation and don’t forget to delete your json file (/etc/docker/daemon.json)
    2. Try again with the docker-compose.yaml and .env from immich’s github

    If your network configuration is wrong from the beginning, you are in for bad times specially if you are going to use duckdns ! Try to make it work on your local network first and than you can go crazy.

    Also if you do not know what you are doing, please don’t make your containers accessible to the web ! Rather use a wireguard server to access all your containers from everywhere in the world with a secure tunnel !

    If you’re a beginner, there is alot to grasp before having a good working laptop server :)

      after hours I tried to change distribution and went with fedora, set up everything, installed immich, not a single problem, it all works, also duckdns, and now I also have btrfs so I can snapshot my system. I’m probably very unlucky with debian based distributions, on my main laptop I had many problems with ubuntu as first distro, I had to distro hop a bit to find my place in EndeavourOS

      thank you very very very very much for your time and help, I really appreciate this! now it’s time to actually start this journey in the magic world of self-hosting!
