There's not much to read here. Look at NixOS Manual, the upstream documentation on containers meanwhile.
Troubleshooting
I have changed the host's channel and some services are no longer functional
Symptoms:
- Lost data in PostgreSQL database
- MySQL has changed its path, where it creates the database
Solution
If you did not have a system.stateVersion option set inside your declarative container configuration, it will use the default one for the channel. Your data might be safe, if you did nothing meanwhile. Add the missing system.stateVersion to your container, rebuild, and possibly stop/start the container.
