在 Amazon EC2 上安装 NixOS

Amazon EC2 是一个广泛使用的云部署平台，隶属于亚马逊网络服务 (AWS)。NixOS 主要通过 AMI 和 nixos-generators 项目支持该平台。

公共 NixOS AMIs

A list of NixOS AMI's available on AWS is located here and for a more up to date list: here (cf. this discourse thread).

The default user for these AMI's is root. There isn't a default password, instead authentication is done by using the SSH key selected during the EC2 creation process.

Creating a NixOS AMI

The nixos-generators project is currently the best method to create your own NixOS AMI. Follow the directions provided by nixos-generators & then follow the instructions provided by AWS.

Troubleshooting

SSH Asks For Password

When connecting to a newly launched EC2 instance via SSH, it may ask for a password. This seems to be because the amazon-init systemd service is still reading user data. Back out of the current SSH attempt and try again in a few minutes.
