Instead of deploying a 3rd party image, we can build our own.
|
|
|
|
We rely on the upstream [`dockerTools`](https://github.com/NixOs/nixpkgs/tree/master/pkgs/built-support/docker) package here.
|
|
Specifically, we can use the `buildImage` function to define our image:
|
|
|
|
{{< source "image.nix" >}}
|
|
|
|
Then we can import this package into our `docker` module:
|
|
|
|
{{< source "default.nix" >}}
|
|
|
|
Now build the image with
|
|
|
|
```sh
|
|
nix build -f . --json config.docker.export
|
|
```
|
|
|
|
Render the generated manifests again and see that it now refers to the newly built tag:
|
|
|
|
```json
|
|

|
"name": "custom"
|
|
}
|
|
]
|
|
}
|
|
}
|
|
],
|
|
"kind": "List",
|
|
"labels": {
|
|
"kubenix/hash": "ac7e4794c3d37f0884e4512a680a30d20e1d6454",

"kubenix/k8s-version": "1.24",
|
|
"kubenix/project-name": "kubenix"
|
|
}
|
|
}
|
|
```
|
|
|
|
Of course, to actually deploy, we need to push the image to our registry. The script defined at {{< option "docker.copyScript" >}} does just that.
|
|
|
|
```sh
|
|
$(nix build -f . --json config.docker.copyScript | jq -r '.[].outputs.out')
|
|
```
|
|
|
|
<!-- TODO: can we make that `nix run -f . config.docker.copyScript` ? -->
