Itzo is the agent that runs on Kip cells (cloud instances) and takes care of managing the lifecycle of pods and containers on the instance. In many ways, itzo performs many of the duties of the kubelet:
Downloading containers
Setting up namespaces
Running and restarting processes
Running probes
Mounting volumes
Capturing logs
Creating Images
Scripts and a packer config building cell images on AWS and GCP can be found here.
