Introduction

Kubernetes is frequently thought of as a platform for stateless workloads because the majority of its resources are ephemeral. However, as Kubernetes grows in popularity, enterprises are deploying more and more stateful apps. Because stateful workloads require permanent storage for application data, you can no longer simply reload them in the event of a disaster.

As businesses invest extensively in Kubernetes and deploy more and more containerized applications across multi-clouds, providing adequate data protection in a distributed environment becomes a challenge that must be addressed.

Data Protection in Tanzu Mission Control (TMC) is provided by Velero which is an open-source project. Velero backups typically include application and cluster data like config maps, custom resource definitions, secrets, and so on, which would then be re-applied to a cluster during restoration. The resources that are using a persistent volume, are backed up using Restic. 

In this post, I’ll show how to backup and recover a stateful application running in a Tanzu Kubernetes cluster.… Read More

Introduction

Data protection in TMC is provided by Velero which is an open-source project that came with the Heptio acquisition.

When data protection is enabled on a Kubernetes cluster, the data backup is stored external to the TMC. TMC supports both AWS S3 and Custom S3 storage locations to store the backups.  Configuring the AWS S3 endpoint is pretty simple as TMC provides a CloudFormation script that does all the backend tasks such as creating S3 buckets, assigning permissions, etc.

AWS S3 might not be a suitable solution in some use cases. For instance, a customer has already invested heavily in an S3 solution (MinIO, Cloudian, etc). TMC allows customers to bring their own self-provisioned AWS S3 bucket or S3-compatible on-prem storage locations for their Kubernetes clusters.

In this post, I will be talking about how you can use on-prem S3 storage for storing Kubernetes backups taken from TMC Data Protection.… Read More

Welcome to Part-3 of the getting started with Tanzu Mission Control. In this post, I will discuss how you can leverage Tanzu Mission Control to protect your Kubernetes workloads that are deployed on the Tanzu Kubernetes Grid cluster. 

If you are new to Tanzu Mission Control, I would encourage you to read previous articles of this series before diving into data protection for K8 workloads.

Tanzu Mission Control & Data Protection

Data protection in TMC is provided by Velero which is an open-source project that came with the Heptio acquisition.

When data protection is enabled on a Kubernetes cluster, the data backup is stored external to the TMC. TMC leverages AWS S3 functionality to store the backups. 

Note: Data protection is not enabled on the Kubernetes cluster by default. In this post, I will demonstrate the steps of enabling data protection and the process of backup and restoration of K8 data. … Read More

In the first post of this blog series, I talked about the Tanzu Mission Control solution and the benefits of using it. I also talked about the architecture and components of TMC. Now it’s time to see TMC in action. 

One of the core features of TMC is K8 cluster lifecycle management and in this post, I will walk through the steps of creating and managing the Kubernetes cluster from the TMC portal. Let’s get started.

TMC Login

To use the TMC solution, you must have a subscription to the Tanzu Mission Control cloud service. You can access the TMC portal by logging into your VMware Cloud Service portal and clicking on the VMware Tanzu Mission Control service tile. 

By default, you will land to the Clusters view from where you can create/attach the existing Kubernetes cluster with the TMC portal.

Note: For the purpose of this demonstration, I will be talking only about TKGm and TKGS cluster in this blog post. … Read More

VMware Tanzu is a portfolio of products and services that enables customers to build modern applications on the Kubernetes platform and manage them from a single control point. The Tanzu portfolio is pretty vast and includes products and services like:

1: Tanzu Kubernetes Grid

2: vSphere with Tanzu

3: Tanzu Mission Control

In this blog post, I will be talking about what is Tanzu Mission Control and why it is important for you.

What is Tanzu Mission Control (TMC) ?

Tanzu Mission Control is a SaaS offering available through VMware Cloud Services and provides:

• A centralized platform to deploy and manage Kubernetes clusters across multiple clouds.
• Attach existing Kubernetes Clusters in the TMC portal for centralized operations and management.
• A Policy Engine that automates Access control and security policies across a fleet of clusters.
• Manage security across multiple clusters.
• Centralize authentication and authorization, with federated identity from multiple sources.
