Multipass Local Virtual Machines Nov 10, 2023

Show notes

Bret and Nirmal are joined by Chris Townsend, the engineering manager for Canonical's Multipass team, to discuss how to use Multipass as the easiest local virtual machine for Docker, Kubernetes and more!

😇 My new GitHub Security workshop has launched! A free 2-hour workshop with hands-on labs to harden your repos and your workflows from common supply chain attacks. I'll cover how attackers are getting in, and then we'll lock down a sample repo so you know what needs to be done to protect your code. You'll leave with a deep understanding of risks and mitigations as well as a list of helpful tools to keep your repos safe, including my new "gasa" tool for scanning your repos and orgs.

Multipass is my go-to solution for quickly creating local virtual machines of Ubuntu. I teach it in my courses, I've used it for many years, and I was excited to have Chris on to talk about the ways to automate the creation of a VM in Multipass, and dig into the various virtualization, backends and networking options.

We also talk about Multipass blueprints where in a demo, he shows off how to create a VM with Docker installed in a single command. It actually reminds me of Docker Machine, if you've been around a while. That also mounts your code directly into the VM and sets a host alias so that the Docker commands will pass through to Docker in the VM transparently.

If you can imagine that it basically means that you can run Docker in the VM and use it from the host as if it isn't in a VM. And then we had some great audience questions about various features of Multipass and how to use it for multi-node clustering and exposing VMs to your local network.

Live recording of the complete show from September 21, 2023 is on YouTube (Ep. #235). Includes demos.

NetBackup for Kubernetes Oct 27, 2023

Show notes

Bret is joined by Demetrius Malbrough and Joseph D'angelo from Veritas, the company that makes NetBackup amongst many other data protection tools.

NetBackup has been around at least 25 years and I've been using it over 20 years, although not recently. So we had the two gentlemen from Veritas on the show to break down the evolution of NetBackup to a Kubernetes native backup solution.

We also talked about additional products that make sense in a backup context, like their InfoScale storage management solution, and we tried to break down some of the technicals. What are we talking about when we mean deploying NetBackup on Kubernetes? How does InfoScale fit into that? And generally, just helping me catch up with the last few years as NetBackup 10.0 has been released.

I asked lots of questions and we got some interesting questions from the audience.

AWS Lambda Containers Oct 20, 2023

Show notes

Bret and Nirmal are joined by Ken Collins, AWS Serverless Hero and Principal Engineer at Custom Ink to discuss all things Lambda and to dig into the details of running containers in serverless.

Ken and I have known each other for probably 15 years in the local tech scene here in coastal Virginia. And I've always respected him for being a leader in that community, always wanting to talk at a meetup or help in some way.

So when he reached out wanting to talk about his company using containers on AWS Lambda, it was an easy sell for me because I knew it would be a great show. And then I learned some of the updates Lambda has had over the years, particularly when it comes to container workflows.

We had some great audience questions and no shortage of topics around using modern Lambda and serverless.

Ephemeral & Preview Environments for Compose and Kubernetes Oct 06, 2023

Show notes

Bret and Nirmal are joined by Grayson Adkins and Josh Thurman on the show. They are co-founders of Uffizzi, an environments-as-a-service company for Docker Compose and Kubernetes.

We talk about ephemeral environments in all their forms. You might call them preview environments, developer environments, or pull release environments, which is my favorite way to use these environments-as-a-service.

But regardless of the many ways to use ephemeral environments, it's great to see a growing set of tools in the cloud native community for automating the spinning up of fresh environments with Kubernetes manifests, helm charts, or even Docker Compose YAML.

Uffizzi is using the open core model, meaning that the core part of their product is open source.

OpenSauced with Brian Douglas Sep 08, 2023

Show notes

In this episode, Bret and Nirmal talk with Brian Douglas of OpenSauced.

Brian Douglas, of GitHub fame, has founded OpenSauced, a cool web app and community of open source developers finding their next contribution and maybe their next job. Brian has so many stories of working with open source projects and having conversations with leading open source contributors, while previously being a lead developer advocate at GitHub. So we definitely spend time talking through some of those stories and learning some of that we didn't know about GitHub and open source being run on it. We then dig into how to use the OpenSauced platform he's creating to find your next open source project and get noticed by employers.

Istio Ambient Mesh and Solo.io Aug 25, 2023

Show notes

Bret and Nirmal welcome Idit Levine, Founder/CEO Solo.io. Idit focuses on Service Mesh, API-GW and Multi-Cloud networking, and security.

Idit has been involved in the Containers/DevOps community for 10+ years, building products from Docker to Envoy to Kubernetes, and now Istio and Cilium. We talk about Istio, Ambient Mesh, Envoy, Zero-Trust Security, Cilium, eBPF, Multi-Cloud and more.

This is not the first time we've talked about Solo or Service Mesh. Ambient Mesh is Solo's new product that simplifies the install and infrastructure costs of essentially running Istio.

I'm really hopeful that this is going to help a lot more people implement Istio because traditionally, it does have a lot of parts and a lot of costs with the sidecar approach, but this new approach reduces the number of essentially proxies and parts that you're running on each node of your Kubernetes cluster.

Future of Kubernetes with Brendan Burns Aug 11, 2023

Show notes

Bret and Matt welcome special guest Brendan Burns, CVP Azure Cloud Native & Resource Management, and also a founding member of the Kubernetes project.

Because Brendan is one of the three original co-founders of the Kubernetes project back in 2013 at Google, he's a little bit internet famous in open source and Cloud Native. So I was a little nervous going into this because I had so many questions.

We took some live questions as we always do from YouTube live, and I thought it was a really great episode of a little mix of talking about Azure and some of the things you can do with containers, some of the things they're working on, some of the things that he's focused on that we haven't seen yet. We talk about AI and how that relates to some of these things.

We even talk about WASM or WebAssembly, one of my favorite topics of the last year, because that's important so it was great to get his perspective.

And I think my favorite part of the show is where we really talk about the next layers of abstraction, or maybe even the ways that we can deploy to Kubernetes or make it simpler to manage and deploy to. And that's been a real challenge for the community ever since Kubernetes was created in making it more accessible to more people, without it being so complex to manage and deal with underneath. And Brendan has some really great views on what it's going to take it to get us there.

Kasten K10 Kubernetes Backups Jul 28, 2023

Show notes

Bret and Matt welcome Michael Cade, the field CTO at Kasten by Veeam.

If you've been around servers for a while, you probably have heard of Veeam. It made its debut back in the late 2000's when virtual machines and implementations of VMs were big. I first found out about them back in those days, because it was a great free product for small virtual machine environments and data centers.

They've made tons of additional backup and recovery products over those years, and now they have Kasten K10, which is a Kubernetes backup and restore/recovery product. Michael discussed with us the origins of K10 and some of the major features.

We get into some demos, which you can check out in the original YouTube live show.
