# Using Nix within Docker

To run the latest stable release of Nix with Docker run the following command:

```console
$ docker run -ti nixos/nix
Unable to find image 'nixos/nix:latest' locally

# What is included in Nix' Docker image?

The official Docker image is created using `pkgs.dockerTools.buildLayeredImage`
(and not with `Dockerfile` as it is usual with Docker images). You can still
base your custom Docker image on it as you would do with any other Docker
image.

The Docker image is also not based on any other image and includes minimal set
of runtime dependencies that are required to use Nix:

 - pkgs.nix
 - pkgs.bashInteractive
 - pkgs.coreutils-full
 - pkgs.gnutar
 - pkgs.gzip
 - pkgs.gnugrep
 - pkgs.which
 - pkgs.curl
 - pkgs.less
 - pkgs.wget
 - pkgs.man
 - pkgs.cacert.out
 - pkgs.findutils

# Docker image with the latest development version of Nix

To get the latest image that was built by [Hydra](https://hydra.nixos.org) run
the following command:

```console
$ curl -L https://hydra.nixos.org/job/nix/master/dockerImage.x86_64-linux/latest/download/1 | docker load
$ docker run -ti nix:2.5pre20211105
```

You can also build a Docker image from source yourself:

```console
$ nix build ./\#hydraJobs.dockerImage.x86_64-linux
$ docker load -i ./result
$ docker run -ti nix:2.5pre20211105
```
