Importing Nixlets

Nixlets can now define dependency Nixlets and handle them similarly to how nested Helm Charts work.

Importing

To define a dependency Nixlet, give it a name and pass the Nixlet as a value:

  nixlet.dependencies."postgres" = <any nixlet>;

<any nixlet> here could be stuff like nixlet-lib.fetchNixletFromGitlab {...}, nixlet-lib.fetchNixlet <url> <sha>, etc.

Defining Values

You can pre-define values for dependency Nixlets like this:

  options = {
    # options for the current Nixlet
  };
  # overwriting the default of dependency Nixlets (the user can still overwrite this using mkForce for example)
  config."postgres".replicaCount = 10;
