Differential Snapshot Controller

This repository contains the source of the differential snapshot controller prototype.

Prerequisites:

• Go
• Docker

To compile the controller Go binary locally:

make compile

This will produce a local binary named diffsnap-controller. To run it:

./diffsnap-controller

To build and push the controller's image:

make build

make push

The image name and tag can be overridden using the IMAGE_NAME and IMAGE_TAG variables.

To deploy to Kubernetes:

kubectl apply -f artifacts/examples/differentialsnapshot.example.com_getchangedblocks.yaml

kubectl apply -f deploy/controller/ns.yaml

kubectl auth reconcile -f deploy/controller/rbac.yaml

kubectl apply -f deploy/controller/deploy.yaml

The controller will be deployed to the new diffsnap namespace.

An example of the GetChangedBlock custom resource can be found in artifacts/examples/getchangedblocks.yaml.

On AWS EKS

Instructions on how to set up an EKS cluster with the CSI snapshot controller and EBS CSI driver can be found in the deploy/eks/README.md file.

Code Generation

To re-generate the CRD clientsets and informers code:

make codegen
