Demo Setup Instructions
I used a Linux Ubuntu 20.04 VM running in vSphere you might need to adjust some settings if done with a different OS or operating environment.
Download and install K3S:
sudo curl -sfL https://get.k3s.io | sh -s – –write-kubeconfig-mode 644
Create a “.kube” folder in your user home folder and copy the default configuration file to that location. Change the ownership and group to your username:
mkdir /home/[username]/.kube
sudo cp /etc/rancher/k3s/k3s.yaml /home/[username]/.kube/config
sudo chown [username]:[username] /home/[username]/.kube/config
Test to see if you can see the single node cluster up and running:
kubectl get nodes
Install helm
sudo snap install helm –classic
Create a test deployment which we will backup:
Kubectl create ns nginx
Open your favorite text editor and paste this deployment yaml into it and save as nginxdeploy.yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: nginxpvcclaim
namespace: nginx
spec:
accessModes:
– ReadWriteOnce

apiVersion: apps/v1
kind: Deployment

containers:

ports:
– containerPort: 80

volumeMounts:
– mountPath: “/usr/share/nginx/html”

Now create the deployment
kubectl create -f nginxdeploy.yaml
Now install Kasten with the following commands
helm install k10 kasten/k10 –namespace=kasten-io –set ingress.create=true –set ingress.class=traefik –set injectKanisterSidecar.enabled=true –set-string injectKanisterSidecar.namespaceSelector.matchLabels.k10/injectKanisterSidecar=true –set auth.tokenAuth.enabled=true
We need to wait for all the pods to come up:
watch kubectl get po -n kasten-io
Ctrl-c to break out of the watch command.
Now let’s check to see that our ingress has been created
kubectl get ing -n kasten-io
In our browser we should be able to get to the dashboard now by typing our address in the above output:
http://your-vm-ip-address/k10/#/
We will need to click on advanced and proceed:
We have access to the dashboard!
To get the authentication token type in the following:
sa_secret=$(kubectl get serviceaccount k10-k10 -o jsonpath=”{.secrets[0].name}” –namespace kasten-io)
and then:
kubectl get secret –namespace kasten-io -ojsonpath= | base64 –decode
Copy everything after the word decode and before you’re your normal prompt (in my case ober@susecon:~$
Paste into the window:
You will have to type and an email and company name but afterwards you should be greeted by the Kasten Dashboard:
In order to perform generic backups, we need to label the namespace where we want Kasten to inject a sidecar container:
Kubectl label ns nginx k10/injectKanisterSidecar=true
We will also have to create a local Minio S3 instance to act as a Location profile. In production you would not want to have this location profile on the same cluster. We will launch a Minio docker container:
mkdir /data
docker run -d \
-p 9000:9000 \
-p 9001:9001 \
minio/minio server /data –console-address “:9001”
Then go to http://your-ip:9001 and you should be able to login with the
Username: minioadmin
Password: minioadmin
In Kasten create a location profile pointing to that location:
Now let’s backup our nginx deployment:
Create a policy like this one:
We can now press run once and the backup will run:
We can go back to the Dashboard and click on the policy running and watch its progress until it completes successfully:
