Our recent SNIA CSTI webcast, “Kubernetes in the Cloud (Part 3): (Almost) Everything You Need to Know about Stateful Workloads” offered a wealth of insight on how to address the challenges of running stateful workloads in Kubernetes. This webcast was the third installment of our Kubernetes in the Cloud webcast series and it is now available on-demand as are “Kubernetes in the Cloud (Part 1)” and “Kubernetes in the Cloud (Part 2).”

Our expert presenters, Paul Burt and Ingo Fuchs, have provided additional resources to help keep you in the know on Kubernetes. Here they all are:

• Anyone running Kubernetes needs to put a bit of thought into how they approach stateful workloads. Containers by their nature are ephemeral. So, what options are there for the average Kubernetes user? This talk aims to provide an overview of the most obvious options, and provide resources for learning more about them. https://twitter.com/kubernetesio/status/840257886202683392 and https://www.youtube.com/watch?v=4x1r3Osu1Kg

Kubernetes is a hot topic these days, generating lots of interest and questions. The goal of our SNIA Cloud Storage Technologies Initiative Kubernetes in the Cloud webcast series is to cut through the hype and provide a vendor neutral look at what Kubernetes is and how it is being used. Our most recent webcast, Kubernetes in the Cloud (Part 2), generated some interesting questions. Here are answers from our expert presenters.

Q. If I'm running my Kubernetes infrastructure at a cloud service provider, do I need CSI support by the cloud provider? If this is not available, I will need a virtual storage array that provides CSI leveraging the underlying cloud storage. Do you know whether there are solutions on the market that I can deploy as a virtual machine at my cloud provider?

A. Current solutions using the CSI interface for public cloud storage are not available at this point. It will be up to the cloud provider to decide whether to support those interfaces to their storage layers.

Q. Does each pod run on one CPU core? I am trying to understand how to size the server configuration?

A. Containers use Linux cgroups to limit the amount of CPU and memory a container can consume and this is exposed in Kubernetes as limits that you can set.

Q. In today’s environment for Kubernetes Flex storage, what is the suggested process to "backup" these stateful PVs or is that not necessary anymore?

A. Backups are still as important with containers as they are today with traditional applications. There are many different approaches available to backup containers: storage snapshots via native storage interfaces, deployment of backup clients in containers, application level backups, etc.

Q. You mentioned Kubernetes a lot - but what is the status of native Docker CSI support? Can I use CSI for usage within Docker without deploying Kubernetes? And if yes: Can I get rid of the need for docker volume drivers then?

A. Docker universal control point (UCP) support of CSI is currently in beta. Once UCP is generally available, we’ll be able to answer your question in more detail.

Kubernetes is great for running stateless workloads, like web servers. It’ll run health checks, restart containers when they crash, and do all sorts of other wonderful things. So, what about stateful workloads? Large implementers like Uber say to avoid it if you can [1], and gurus like Kelsey Hightower echo that sentiment [2].

It’s the topic we’ll address on August 20^th at our live SNIA Cloud Storage Technologies Initiative webcast “Kubernetes in the Cloud (Part 3): Stateful Workloads.”  In this session, we’ll explore when it’s appropriate to run a stateful workload in cluster, or out. We’ll discuss the best options for running a workload like a database on the cloud, or in the cluster, and what’s needed to set that up.

We’ll cover:

• Secrets management
• Running a database on a VM and connecting it to Kubernetes as a service
• Running a database in Kubernetes using a `stateful set`
• Running a database in Kubernetes using an Operator
• Running a database on a cloud managed service

Register today to save your place on August 20^th. This is the 3^rd installment of our Kubernetes in the Cloud webcast series. Kubernetes in the Cloud (Part 1) and Kubernetes in the Cloud (Part 2) are available on demand. I encourage you to check them out for great information and demonstrations on Kubernetes.
