Katbox

Katbox is an inline ephemeral volume manager with delayed deletion for Kubernetes.

It is inspired by the "Sandbox" functionality provided by Apache Mesos.

Pre-requisite

• Kubernetes cluster
• Running version 1.18 or later
• Access to terminal with kubectl installed

Deployment

Deployment varies depending on the Kubernetes version your cluster is running:

• Deployment for Kubernetes 1.18 and later

Examples

Assuming katbox has been successfully deployed, the following example can be run using kubectl:

$ kubectl apply -f https://raw.githubusercontent.com/paypal/katbox/main/examples/csi-app-inline.yaml

Building the binaries

To build the driver, run the following command from the root of the repository:

make

Building a docker image

To build a docker image to be used on a kubernetes cluster, run the following command from the root of the repository:

docker build . -t <image name>
