# darwin.builder {#sec-darwin-builder}

-
`darwin.builder` provides a way to bootstrap a Linux builder on a macOS machine.
4
5
This requires macOS version 12.4 or later.
6
7
-
This also requires that port 22 on your machine is free (since Nix does not
8
-
permit specifying a non-default SSH port for builders).
9
10
You will also need to be a trusted user for your Nix installation. In other
11
words, your `/etc/nix/nix.conf` should have something like:
···
17
To launch the builder, run the following flake:
18
19
```ShellSession
20
-
$ nix run nixpkgs#darwin.builder
21
```
22
23
That will prompt you to enter your `sudo` password:
···
50
```
51
# - Replace ${ARCH} with either aarch64 or x86_64 to match your host machine
52
# - Replace ${MAX_JOBS} with the maximum number of builds (pick 4 if you're not sure)
53
-
builders = ssh-ng://builder@localhost ${ARCH}-linux /etc/nix/builder_ed25519 ${MAX_JOBS} - - - c3NoLWVkMjU1MTkgQUFBQUMzTnphQzFsWkRJMU5URTVBQUFBSUpCV2N4Yi9CbGFxdDFhdU90RStGOFFVV3JVb3RpQzVxQkorVXVFV2RWQ2Igcm9vdEBuaXhvcwo=
54
55
# Not strictly necessary, but this will reduce your disk utilization
56
builders-use-substitutes = true

# darwin.linux-builder {#sec-darwin-builder}
2
3
+
`darwin.linux-builder` provides a way to bootstrap a Linux builder on a macOS machine.
4
5
This requires macOS version 12.4 or later.
6
7
+
The builder runs on host port 31022 by default.
8
+
You can change it by overriding `virtualisation.darwin-builder.hostPort`.
9
+
See the [example](#sec-darwin-builder-example-flake).
10
11
You will also need to be a trusted user for your Nix installation. In other
12
words, your `/etc/nix/nix.conf` should have something like:
···
18
To launch the builder, run the following flake:
19
20
```ShellSession
21

23
24
That will prompt you to enter your `sudo` password:
···
51
```
52
# - Replace ${ARCH} with either aarch64 or x86_64 to match your host machine
53
# - Replace ${MAX_JOBS} with the maximum number of builds (pick 4 if you're not sure)
54

56
# Not strictly necessary, but this will reduce your disk utilization
57
builders-use-substitutes = true
58
+
```
59
+
60
+
To allow Nix to connect to a builder not running on port 22, you will also need to create a new file at `/etc/ssh/ssh_config.d/100-linux-builder.conf`:
61
+
62
+
```
63
+
Host linux-builder
64
+
Hostname localhost
65
+
HostKeyAlias linux-builder
66
+
Port 31022

218

# daemon socket, and the in-process RemoteStore instance will disable
219

# itself. This makes retries infeasible even for services that are
220

# aware of the issue. Failure to connect can affect not only new client
