How-to migrate from other tools to wire tool.

Migrate from...

From Colmena ​

If you're familiar with colmena, wire will hopefully come quickly to you! (or, atleast that was the intention when writing it!). There are a few changes you should know:

  • You don't have to use a root user
  • apply-local does not exist, apply will apply locally when appropriate
  • Many options have been aliased to nicer names (ie, deployment.targetUser <=> deployment.target.user)
  • You may pass a list of hosts to deployment.targetHost (no more fiddling with your hive whenever DNS is down, for example)
  • --path optionally takes a flakeref! You can pass --path github:foo/bar, --path git+file:///..., --path https://.../main.tar.gz, etc. (plain paths like --path ~/my-hive still work as always)

TIP

You should also follow installation to install the binary.

Convert a Hive as a Flake ​

flake.nix
nix
{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    colmena.url = "github:zhaofengli/colmena"; 
    wire.url = "github:forallsys/wire/stable"; 
  };
  outputs =
    { nixpkgs, colmena, ... }:
    {
      colmenaHive = colmena.lib.makeHive { 
      wire = wire.lib.makeHive { 
        # ..
      };
    };
}

Convert a Hive with npins ​

TIP

You should also follow installation to setup npins and install the binary.

Unlike colmena, you must call makeHive directly even in non-flake hives.

hive.nix
nix
let
  sources = import ./npins;
  wire = import sources.wire;
in
{ 
wire.makeHive {

  meta.nixpkgs = <nixpkgs>; 
  meta.nixpkgs = import sources.nixpkgs { }; 

  # ...
}

Replacing <nixpkgs> with a pinned source is optional, but you should probably use one if you ask me :)

From nixos-rebuild ​

You can keep using nixos-rebuild alongside wire!
