# Provs framework
Provs is a framework for automating tasks for provisioning reasons and other purposes.

It combines
* being able to use the power of shell commands
* a clear and detailed result summary of the built-in execution handling (incl. failure handling and reporting)
* the convenience and robustness of a modern programming language


### Write once, run everywhere

Tasks can be run

* locally
* remotely
* in a local docker container
* in a remote container

Additionally, it is possible to define a custom processor if needed.

* Download the latest `provs-desktop.jar` from: https://gitlab.com/domaindrivenarchitecture/provs/-/releases
* Make the jar-file executable by `chmod +x provs-desktop.jar`
* For server functionality (e.g. k3s) download the latest `provs-server.jar` from: https://gitlab.com/domaindrivenarchitecture/provs/-/releases
