Why built the config locally? #5

Closed gador closed 1 year ago

gador commented 1 year ago

Is there a reason why the config is build locally on the deployment server?

The only reason I can think of is to check for build errors. But if I see it correctly, the nixos-rebuild happens locally on the client, right? So if something would be wrong with the config, the client would return an error code?

My use case is: I have a deployment server for several machines with a mixture of aarch64-linux and x86_64-linux and rebuild for every machine takes quite a while. It would speed up the process immensely if the config doesn't need to be build by the deployment server every time.

The idea was to build everything locally and to use the machine as a substituter for other if desired, and also to ensure the configuration was working.

If you replace build by dry-build in https://github.com/rapenne-s/bento/blob/main/bento#L532 it should just check the configuration is valid, without building anything.

If it's not enough, or not working, use dry-build instead of $2 in https://github.com/rapenne-s/bento/blob/main/bento#L421
