# deploy-rs
|
|
|
|
[Deploy-rs][d-rs] is a tool for managing NixOS remote machines. It was
|
|
chosen for devos after the author experienced some frustrations with the
|
|
stateful nature of nixops' db. It was also designed from scratch to support
|
|
flake based deployments, and so is an excellent tool for the job.
|
|
|
|
By default, all the [hosts](../concepts/hosts.md) are also available as deploy-rs nodes,
|
|
configured with the hostname set to `networking.hostName`; overridable via
|
|
the command line.
|
|
|
|
## Usage
|
|
|
|
Just add your ssh key to the host:
|
|
|
|
```nix
|
|
{ ... }:
|
|
{
|
|
users.users.${sshUser}.openssh.authorizedKeys.keyFiles = [
|
|
../secrets/path/to/key.pub
|
|
];
|
|
}
|
|
```
|
|
|
|
And the private key to your user:
|
|
|
|
```nix
|
|
{ ... }:
|
|
{
|
|
home-manager.users.${sshUser}.programs.ssh = {
|
|
enable = true;
|
|
|
|
matchBlocks = {
|
|
${host} = {
|
|
host = hostName;
|
|
identityFile = ../secrets/path/to/key;
|
|
extraOptions = { AddKeysToAgent = "yes"; };
|
|
};
|
|
};
|
|
}
|
|
}
|
|
```
|
|
|
|
And run the deployment:
|
|
|
|
```sh
|
|
deploy '.#hostName' --hostname host.example.com
|
|
```
|
|
|
|
> ##### _Note:_
|
|
>
|
|
> Your user will need **passwordless** sudo access

### Home Manager
|
|
|
|
Digga's `lib.mkDeployNodes` provides only `system` profile.
|
|
In order to deploy your `home-manager` configuration you should provide additional profile(s) to deploy-rs config:
|
|
|
|
```nix
|
|
# Initially, this line looks like this: deploy.nodes = digga.lib.mkDeployNodes self.nixosConfigurations { };
|
|
deploy.nodes = digga.lib.mkDeployNodes self.nixosConfigurations
|
|
{
|
|
<HOSTNAME> = {
|
|
profilesOrder = [ "system" "<HM_PROFILE>" "<ANOTHER_HM_PROFILE>"];
|
|
profiles.<HM_PROFILE> = {
|
|
user = "<YOUR_USERNAME>";
|
|
path = deploy.lib.x86_64-linux.activate.home-manager self.homeConfigurationsPortable.x86_64-linux.<YOUR_USERNAME>;
|
|
};
|
|
profiles.<ANOTHER_HM_PROFILE> = {
|
|
user = "<ANOTHER_USERNAME>";
|
|
path = deploy.lib.x86_64-linux.activate.home-manager self.homeConfigurationsPortable.x86_64-linux.<ANOTHER_USERNAME>;
|
|
};
|
|
};
|
|
};
|
|
```
|
|
|
|
Substitute `<HOSTNAME>`, `<HM_PROFILE>` and `<YOUR_USERNAME>` placeholders (omitting the `<>`).
|
|
|
|
`<ANOTHER_HM_PROFILE>` is there to illustrate deploying multiple `home-manager` configurations. Either substitute those as well,
|
|
or remove them altogether. Don't forget the `profileOrder` variable.
