Livebook
Livebook is a web application for writing interactive and collaborative code notebooks.
Basic Usage
Enabling the livebook service creates a user
systemd unit
which runs the server.
{ ... }:
{
services.livebook = {
enableUserService = true;
port = 20123;
# See note below about security
environmentFile = pkgs.writeText "livebook.env" ''
LIVEBOOK_PASSWORD = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
'';
};
}
::: {.note}
The Livebook server has the ability to run any command as the user it is running under, so securing access to it with a password is highly recommended.
Putting the password in the Nix configuration like above is an easy
way to get started but it is not recommended in the real world because
the livebook.env file will be added to the world-readable Nix store.
A better approach would be to put the password in some secure
user-readable location and set environmentFile = /home/user/secure/livebook.env.

Extra dependencies
By default, the Livebook service is run with minimum dependencies, but
some features require additional packages. For example, the machine
learning Kinos require gcc and gnumake. To add these, use
extraPackages:
services.livebook.extraPackages = with pkgs; [ gcc gnumake ];
