I added nixops.nix file with this content to the home directory:

{
  network.storage.legacy = {
    databasefile = "~/.nixops/deployments.nixops";
  };
}

Nixops started working. If I change the working directory, then nixops stops working again.

How to make nixops always read ~/nixops.nix file?

onny · 2021-09-24T19:23:17Z

I guess you'll have to rename your main configuration or deployment file to nixops.nix. This is a naming convention introduced in NixOps 2.0 https://nixops.readthedocs.io/en/latest/manual/migrating.html

Izorkin · 2021-09-24T19:36:04Z

Even after renaming, nixops will look configuration in ./flake.nix.
If I go to the folder with the nixpkgs source files - cd ~/src/nixpkgs, then nixops stops working.
In the current variant, it becomes inconvenient to test changes in nixpkgs by deploying the configuration to a test variational machine using nixops.

adisbladis · 2021-09-24T20:20:55Z

You can always explicitly pass the path to your deployment.

This is intended behaviour.

Izorkin · 2021-09-24T21:43:33Z

And if make such a parameter in the file ~/.config/nixpkgs/config.nix ?

{
  nixopsNetworkDir = "~/works/nixops/example";
}
