NixOps
NixOps is a tool for deploying to NixOS machines in a network or the cloud. Key features include:
- Declarative: NixOps determines and carries out actions necessary to realise a deployment configuration.
- Testable: Try your deployments on VirtualBox or libvirtd.
- Multi Cloud Support: Currently supports deployments to AWS, Hetzner, and GCE
- Separation of Concerns: Deployment descriptions are divided into logical and physical aspects. This makes it easy to separate parts that say what a machine should do from where they should do it.
- Extensible: NixOps is extensible through a plugin infrastructure which can be used to provide additional backends.
For more information, please refer to the NixOps manual.
