==============================================================================

📚 Let's go Install Kasten K10 now, take a break from ads, right?

Because, I can hear you saying enough advertising KEREM !😁

📍STEP 1

Install HELM 3 or HELM 2 named "Bundle Package Orchestrator Manager" if you don't have it on your Core-Kubernetes Stack, you must download and install from here: https://github.com/helm/helm.

The most common problem during helm use is the taking of Tiller package errors. This problem is generally simple to resolve.

First of all, you must bring your Helm & Tiller Pack to the latest version and give Tiller authorized permission in RBAC on your Helm Repo packages. That's how these mistakes are mostly handled.. :)

sudo snap install helm --classic (*works only Ubuntu,I guess..)`

📍STEP 2

The CSI external-snapshotter sidecar only watches for VolumeSnapshotContent create/update/delete events. Also Kubernetes external snapshotter “watches Kubernetes Snapshot CRD objects and triggers CreateSnapshot/DeleteSnapshot against a CSI endpoint”

$ git clone https://github.com/kubernetes-csi/external-snapshotter

📍STEP 3

$ cd external-snapshotter $ git checkout release-2.0 $ kubectl apply -f config/crd -f deploy/kubernetes/snapshot-controller

📍STEP 4

$ kubectl create -f-

apiVersion: snapshot.storage.k8s.io/v1beta1
kind: VolumeSnapshotClass
metadata:
  name: vmwarecsi-snapshot
  annotations:
    snapshot.storage.kubernetes.io/is-default-class: "true"
driver: csi.k8s.com
deletionPolicy: Delete
parameters:
  description: "Snapshot created by the VMware/RedHat or Any Supported Vendor CSI Driver"
  csi.storage.k8s.io/snapshotter-secret-name: vmware-backend
  csi.storage.k8s.io/snapshotter-secret-namespace: kube-system

Note: Please refer to this site for CSI Yaml Config. Because mine's just an example,no guaranteed of your side as you know.

For VMware: https://vsphere-csi-driver.sigs.k8s.io/

There are so many vendor has CSI Driver for Kubernetes Stack, Please check the Vendors Official Support Site.

📍STEP 5

https://docs.kasten.io/latest/install/storage.html#csi-snapshot-configuration

$ kubectl annotate volumesnapshotclass hpe-snapshot k10.kasten.io/is-snapshot-class=true

===========

  • You need to check and configure before you install Kasten's K10 platform on Kubernetes !

$ curl https://docs.kasten.io/tools/k10_primer.sh | bash

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

Checking for tools
 --> Found kubectl
 --> Found helm
Checking if the Kasten Helm repo is present
Error: Couldn't load repositories file (/root/.helm/repository/repositories.yaml).
 --> The Kasten Helm repo was not found
Checking for required Helm Tiller version (>= v2.16.0)
Error: could not find tiller
 --> Error when running 'helm version'
Preflight checks failed

======================================================================================

📍STEP 6

$helm init

  • Note: If tiller is already installed please use helm init --client-only or helm init --client-only --skip-refresh

  • If you have "Service Account tiller not found" error in ReplicateSet, you can use this RBAC.yaml for quick-fix ;)

$ cat tiller-rbac.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
 name: tiller
 namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
 name: tiller
roleRef:
  apiGroup: rbac.authotization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: tiller
    namespace: kube-system

OR

You can use it by cli as the below:

kubectl --namespace kube-system create sa tiller
kubectl create clusterrolebinding tiller --clusterrole cluster-admin --serviceaccount=kube-system:tiller
helm init --service-account tiller

📍STEP 7

  • Create kasten-io namespace if have not done it yet (Optional-It's not necessary)

kubectl create namespace kasten-io

📍STEP 8

  • Install add Kasten K10 Helm Repo on Kubernetes or Tanzu, Openshift related Distribution;

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

helm repo update => It's Important !!

📍STEP 9

  • Let's Start to Install Kasten K10 by Veaam

helm install kasten/k10 --name=k10 --namespace=kasten-io --set persistence.storageClass=hostpath

📍STEP 10

  • Check the K10 Pods until pods appears running-state

watch -n5 kubectl get pods --namespace kasten-io

kubectl get pods --namespace kasten-io
NAMESPACE     NAME                                    READY   STATUS    RESTARTS   AGE
kasten-io     aggregatedapis-svc-f72d26hn8-8zsr0      1/1     Running   0          4m12s
kasten-io     auth-svc-8d26hc6461-9c9fb               1/1     Running   0          4m12s
kasten-io     catalog-svc-c71103fkp-62tyl             2/2     Running   0          4m12s
etc...

You should see apx. that 20 Pods working running state as the above !

📍STEP 11

  • Configure port forwarding for the gateway service to allow access for Kasten Web Browser Interface.

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

  • The K10 dashboard will be available at http://127.0.0.1:8080/k10/#/

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

========================================================================================

Now it's time to Install a Sample Database App and Delete Table and The Most Delicious Final Part Backup & Restore A Table from MARIADB 😉

📍STEP 1

kubectl create ns mariadb

You can take also backup with MySQL as the follows below link:

Link: https://blog.kasten.io/kubernetes-backup-and-restore-for-mysql

📍STEP 2

helm install -f values.yaml -n mariadb keremceliker-db bitnami/mariadb

📍STEP 3

You can learn Maria Database Root => Password as the follows below:

kubectl get secret --namespace mariadb keremceliker-db -o jsonpath="{.data.mariadb-root-password}" | base64 --decode

📍STEP 4

Run a Pod that you can use as a client

kubectl run keremcelker-db-client --rm --tty -i --restart='Never' --image docker.io/bitnami/mariadb:10.5.6-debian-10-r0 --namespace mariadb --command -- bash

mysql -h keremceliker-db.mariadb.svc.cluster.local -u root -p K@$t€n2021!

📍STEP 5

📍STEP 6

Click to details tab for View application details and related resources.

📍STEP 7

git clone https://github.com/datacharmer/test_db
cd test_db

Login to MySQL Server:

mysql -h 127.0.0.1 -u root -p admin -P 3306

📍STEP 8

mysql> show databases

add database chart picture

exit

mysql -h 127.0.0.1 -u root -p admin -P 3306 < employees.sql

mysql -h 127.0.0.1 -u root -p admin -P 3306 -t < test_employees_sha.sql

Please Check the MariaDB Chart Picture !

📍STEP 9

Click a Snapshot as Get Backup for Manually create a restore point for this application

Important: Kasten can also take snapshots of applications and their settings.

📍STEP 10

kubectl get -n mariadb volumesnapshots

mysql -h 127.0.0.1 -u root -p admin -P 3306

mysql> show databases

Please Check the MariaDB Tables Chart !

mysql>  use employees;
mysql> delete from departments;

📍STEP 11

Please Check the Deleted MariaDB Database in CHART !

mysql -h 127.0.0.1 -u root -p admin -P 3306 -t < test_employees_sha.sql

📍STEP 12

Finally, we must view restore points for mariadb and Restore to the same or different namespace...

kubectl get --raw /apis/apps.kio.kasten.io/v1alpha1/namespaces/mariadb/restorepointcontents/keremceliker-mariadb-sib539/details

List restore point in namespace 'MariaDB-App'

kubectl get restorepoints.apps.kio.kasten.io --namespace mariadb

📍STEP 13

Please Check the MariaDB Datbases Databases Chart After Restore !

mysql -h 127.0.0.1 -u root -p admin -P 3306 -t < test_employees_sha.sql
