Tanzu Mission Control – Using custom policies to ensure Kasten protects a deployed application

The Issue

A while ago I was chatting to Michael Cade, and we pondered the question “How do we ensure Kasten is protecting a newly deployed application in our Kubernetes environment”.

We chatted about how one of the best ways to make your Kasten protection policy flexible is by using metadata labels.

We came up with the simple idea: “What if something forces a known label on the metadata of any applications deployed by our developers in the future?”

This blog post covers this use case using Tanzu Mission Control with custom policies.

The Solution

One of the products we can use to enforce labels on a Kubernetes resource is Open Policy Agent Gatekeeper. Which is an external admission controller which allows you to create policies for the admission of resource creation/changes/updates based on a criteria.

  • OPA policies are expressed in a high-level declarative language called Rego. (Pronounced “ray-go”.)

Tanzu Mission Control, the fleet management SaaS tool for managing your Kubernetes platforms, provides you the ability to create policies of various types to manage the operation and security posture of your Kubernetes clusters and other organizational objects, implemented by using the OPA Gatekeeper.

Implementing The Solution

For this solution “art of the possible” blog post, we are going to keep it really simple, and implement a policy which covers the following: Continue reading Tanzu Mission Control – Using custom policies to ensure Kasten protects a deployed application

Kubestr – Open-Source Kubernetes Storage benchmarking tool

Kubernetes is a platform which is starting to lose the need for introduction in most settings. However, it still can be a complex beast to get to grips with, and getting your infrastructure components configured correctly is key to providing a successful Kubernetes environment for your applications.

One of these such areas is storage.

With your Kubernetes platform, you need to ensure a correct storage configuration, and benchmark your storage performance, like you would with any other platform. Then test the container storage features such as snapshots of the persistent volumes.

The configuration for each vendor when integrating with Kubernetes will be different, but the outcomes should be the same.

What is Kubestr?

Enter Kubestr, the Open-Source project tool from Kasten by Veeam, designed to help with ensuring your storage is configured correctly, help you benchmark the performance and test features such as snapshots.

Getting started with Kubestr

Simply Download Kubestr for the platform you wish to run the tool from. For me I’ll be running it from my Mac OS X machine, which has connectivity to my Kubernetes platform (AWS EKS, I used this blog to create it).

I extracted the zip file and have the Kubestr command line tool available in the output folder.

kubestr download and extract

Running the tool for the first time will run some tests and output a number of useful items of information on how we can use the tool. Which I will start to breakdown as we continue.

For Kubestr to run, it will use the active context in your kubectl configuration file.

kubestr first run

Green Box – we have our initial checks.

  • Kubernetes version
  • RBAC check
  • Kubernetes Aggregated layer check

Then we have the details from our available storage provisioners that are installed for our cluster. You can see what I have two installed. Continue reading Kubestr – Open-Source Kubernetes Storage benchmarking tool

VMUG Recording – Protecting your Tanzu Kubernetes Workload with Kasten by Veeam

Below is the recording from my London VMUG session with Michael Cade.

  • Title: Protecting your Tanzu Kubernetes Workload with Kasten by Veeam
  • Recorded: 4th February 2021
  • Abstract:
    • This technical demo led session will take you through how to deploy Kasten in your Tanzu Kubernetes environment to protect your container workloads.

How to backup and restore your container workloads using Kasten by Veeam

This blog posts covers using Kasten by Veeam to create backup policies for data protection, and how to restore your data. This blog post follows on from the two installation guides;

Deploying a PacMan browser game as test application

To provide a demo mission critical application for this blog post, I’ve deployed PacMan into my OpenShift cluster, which is accessible via a web browser to play. You can find the files from this GitHub repo to deploy into your own environment.

pacman

This application uses MongoDB to store the scores from the games to give me persistent data stored on a PVC.

pacman high scores

You can see all of the PacMan resources below by running:

kubectl get all -n pacman

kubectl get all -n pacman

Creating a Policy to protect your deployment and data

Log into your Kasten Dashboard.

If you have not yet deployed and configured Kasten, please see these earlier blog posts.

- Installing Kasten for Red Hat OpenShift
- Installing Kasten for VMware Tanzu Kubernetes

On the Kasten dashboard, click the Policy tile (or new policy link within the tile).

Installing and configuring Kasten to protect container workloads on VMware Tanzu Kubernetes Grid

This blog post will take you through the full steps on installing and configuring Kasten, the container based enterprise backup software now owned by Veeam Software

This deployment will be for VMware Tanzu Kubernetes Grid which is running on top of VMware vSphere.

You can read how to create backup policies and restore your data in this blog post.

For the data protection demo, I’ll be using my trusty Pac-Man application that has data persistence using MongoDB.

Installing Kasten on Tanzu Kubernetes Grid

In this guide, I am going to use Helm, you can learn how to install it here.

Add the Kasten Helm charts repo.

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

Create a Kubernetes namespace called “kasten-io”

kubectl create namespace kasten-io

kubectl create namespace kasten-io

Next we are going to use Helm to install the Kasten software into our Tanzu Kubernetes Grid cluster.

helm install k10 kasten/k10 --namespace=kasten-io \
--set externalGateway.create=true \
--set auth.tokenAuth.enabled=true \
--set global.persistence.storageClass=<storage-class-name>

Breaking down the command arguments;

  • –set externalGateway.crete=true
    • This creates an external service to use ServiceType=LoadBalancer to allow external access to the Kasten K10 Dashboard outside of your cluster.
  • –set auth.tokenAuth.enabled=true
  • –set global.persistence.storageClass=<storage-class-name>
    • This sets the storage class to be used for the PV/PVCs to be created for the Kasten install. (In a TKG guest cluster there may not be a default storage class.)

You will be presented an output similar to the below.

NAME: k10
LAST DEPLOYED: Fri Feb 26 01:17:55 2021
NAMESPACE: kasten-io
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
Thank you for installing Kasten’s K10 Data Management Platform!

Documentation can be found at https://docs.kasten.io/.

How to access the K10 Dashboard:

The K10 dashboard is not exposed externally. To establish a connection to it use the following

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

The Kasten dashboard will be available at: `http://127.0.0.1:8080/k10/#/`


The K10 Dashboard is accessible via a LoadBalancer. Find the service's EXTERNAL IP using:
`kubectl get svc gateway-ext --namespace kasten-io -o wide`
And use it in following URL
`http://SERVICE_EXTERNAL_IP/k10/#/`

It will take a few minutes for your pods to be running, you can review with the following command;

kubectl get pods -n kasten-io

 kubectl get pods -n kasten-io

Next we need to get our LoadBalancer IP address for the External Web Front End, so that we can connect to the Kasten K10 Dashboard.

kubectl get svc -n kasten-io
