Kasten K10 Installation on Kind

Prerequisites

  • kind v0.8.1 or higher
  • Kubernetes v1.17 or higher
  • VolumeSnapshot beta CRDs and the Snapshot Controller
  • The CSI Hostpath Driver
    https://github.com/kubernetes-csi/csi-driver-host-path

Installation Setup

Before proceeding, ensure you have the following prerequisites in place: - Kind: v0.8.1 or higher - Kubernetes: v1.17 or higher - VolumeSnapshot CRDs and the Snapshot Controller: These components are essential for managing volume snapshots in Kubernetes. - CSI Hostpath Driver: A Container Storage Interface (CSI) driver that provisions storage directly from the host's filesystem. This is suitable for Kind clusters.

1. Install Kubernetes with Kind

  • Create a Kubernetes cluster using Kind. We'll use Kubernetes v1.25.8 in this example:

Apply VolumeSnapShot CRDS

kubectl apply -f https://raw.githubusercontent.com/kubernetes-csi/external-snapshotter/master/deploy/kubernetes/snapshot-controller/setup-snapshot-controller.yaml

Install the CSI Hostpath Driver

git clone https://github.com/kubernetes-csi/csi-driver-host-path.git

cd csi-driver-host-path

./deploy/kubernetes-1.25/deploy.sh
After the install is complete, add the CSI Hostpath Driver StorageClass and make it the default

Apply the yaml file from the external-snapshotter/examples/kubernetes

Configure CSI Hostpath Driver StorageClass

kubectl apply -f ./examples/csi-storageclass.yaml

kubectl patch storageclass standard \
    -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'

kubectl patch storageclass csi-hostpath-sc \
    -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

Installing K10

helm repo add kasten https://charts.kasten.io/

Install the chart

helm install my-k10 kasten/k10 --version 6.0.2  --namespace=kasten-io

Annotate the CSI Hostpath VolumeSnapshotClass for use with K10

kubectl annotate volumesnapshotclass csi-hostpath-snapclass \
k10.kasten.io/is-snapshot-class=true

Validating the Install

kubectl get pods --namespace kasten-io --watch

Validate Dashboard Access

kubectl --namespace kasten-io port-forward service/gateway 8080:8000

The K10 dashboard will be available at http://127.0.0.1:8080/release-name/#/.
