chaosblade
WIP: I'm working in a fork atm and will push regularly to main repo.
Description
chaosblade is a module that will activate chaos engineering with puppet. Chaos engineering can be used to test your environment for stability. Train engineers to solve, detect problems. In short applying chaos engineering to your environment will gain you valuable isights that can be used to improve your environment.
Setup
The chaosblade executable needs to be active on the server for it to launch chaos experiments. This can be done with include chaosblade. Which will just download the exec from the github and create a symlink so it should be able to be used globally.
