### Pro
|
|
|
|
|
|
|
|
|
|
* very lightweight, it is just a lib
|
|
|
|
|
* precise versioning of [NixPkgs](https://github.com/NixOS/nixpkgs)
|
|
|
|
|
you can specify nixpkgs commit/branch/tag you want to roll out on which machine.
|
|
|
|
|
( your server runs `18.03` and your desktop `unstable` )
|
|
|
|
|
* native [password-store](https://www.passwordstore.org/) support.
|
|
|
|
|
* You can rerun you deployment on the machine itself using `nixos-rebuild switch`.
|
|
|
|
|
* No Database needed.
|
|
|
|
|
* Build/Download happens on the target system.
|
|
|
|
|
|
|
|
|
|
### Con
|
|
|
|
|
|
|
|
|
|
* you need to have git installed (yeah not a real con)
|
|
|
|
|
* not as good documented as NixOps.
|
|
|
|
|
* works only on NixOs *(?)*
|
|
|
|

|
|
|
## NixOps
|
|
|
|
|
|
|
|
|
|
### Pro
|
|
|
|
|
|
|
|
|
|
* well documented
|
|
|
|
|
|
|
|
|
|
### Con
|
|
|
|
|
|
|
|
|
|
* quite heavy
|
|
|
|
|
* host channel is roled out on servers ( not possible to have different channels on different servers )
|
|
|
|
|
* can't just run `nixos-rebuild switch` on the target machines.
|
|
|
|
|
* you need a database (for some reason).
|
|
|
|
|
* Build/Download happens on deploying machine, which is bad when you have a bad internet-connection.
