=== Kubernetes operator for managing container checkpoints ===
'''Summary:''' Develop a Kubernetes operator that automates the management of container checkpoints
Container checkpointing has recently been introduced as an alpha feature in Kubernetes.
To enable this feature, the kubelet API was extended with an endpoint that enables the
creation of checkpoints for individual containers. By default, all container checkpoints
are stored as tar archives in <code>/var/lib/kubelet/checkpoints</code> using the following
file name format: <code>checkpoint-<pod-name>_<namespace-name>-<container-name>-<timestamp>.tar</code>.
However, the current implementation does not provide a mechanism for limiting the number
of checkpoints, which may lead to filling up all existing disk space. This project aims to
develop a Kubernetes operator that automates the management of checkpoints and provides
a garbage collection mechanism to discard obsolete checkpoints.
