Puppet

Puppet is a service just for being controlled.

Usage

you can run a puppet by docker:

docker run --name puppet pigeonligh/puppet

and then you can control it:

docker exec puppet ctr sleep 10s
# or
docker exec puppet ctr exit 1

Why puppet?

Puppet can be used to simulate task and change status of task. For example, you can run puppet in Kubernetes Job and observe the actions of Job Controller.
