DevOps and Docker Talk: Cloud Native Interviews and Tooling

Bret and Nirmal are joined by Dan Lorenc from Chainguard to walk them through Chainguard's approach to building secure, minimal container images for popular open source software. They discuss why it is important to have secure and minimal container images. Dan explains how Chainguard helps remove the pain of CVEs, laggy software updates and patches and much more. Chainguard is now available also on Docker Hub. They spend the first part of the show talking about the week's big news: the XZ supply chain attack, and Dan was the best man to explain it. They also touch on CVEs, things you can do to reduce the attack surface, SLSA, and more during this jam-packed show. Be sure to check out the live recording of the complete show from April 4, 2024 on YouTube (Ep. 261). ★Topics★ Chainguard Website Vulnerability Management Certification course True Cost of Vulnerability Management Chainguard Images Chainguard on Docker Hub Announcement Creators & Guests Cristi CotovanBeth FisherBret FisherNirmal MehtaDan Lorenc You can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!

Bret and Nirmal are joined by Phil Estes of AWS to show us the Finch project, which bundles the best open source tools for building and running containers locally. Now it runs on macOS and Windows WSL2. We've been talking with Phil about this show for months, and now that Finch has come to Windows, we thought it was the best time to clue you in as to why AWS created the Finch project and what it does. You've probably heard of containerd, the most popular container runtime on the planet and BuildKit, the best way, in my opinion, to build container images. Those two work hand in hand in Docker and many other container tools. But you might not have heard of nerdctl or Lima, which are also open source tools that work with containerd and BuildKit to help you run containers locally in a virtual machine. Well, AWS had the idea of making an easy installer for these four tools. That's how Finch was born. Finch is not meant to be a replacement of your existing way to run containers. The tools it installs are a bit of a minimum feature set, if you will, and more focused on providing people the exact tools AWS uses in its container platforms, mainly containerd and BuildKit, which are everywhere in AWS. Rather than building something that's feature equivalent to other local container solutions like Docker Desktop and Rancher Desktop, Finch keeps it simple and does the bare minimum. If you just want an easily installable and minimal way to build and run local containers at the command line with no goofy, high-end fancy features, pure open source and just on Mac and Windows, at least at this point, you should give Finch a try.

Bret is joined by Neil Cresswell, CEO and co-founder of Portainer, to show us new features in Portainer and how it can manage, deploy, and orchestrate all your container workloads from a single Docker Engine, all the way to multi-cluster and IoT Kubernetes deployments. Portainer is much more comprehensive than you might think. Docker on the Edge, Podman, Kubernetes, in the cloud, in hybrid, you name it; it seems that Portainer supports it. In the show, we also get some updates on new things that have happened in the last couple of years, including adding GitOps support to Portainer, the ability to deploy Kubernetes nodes, and infrastructure.

Bret and Nirmal are joined by Ivan Burazin and Chad Metcalf to debut Daytona, an open source "codespaces equivalent." Daytona is a development environment manager designed to automate all the tedious steps a developer needs to perform to set up their development environment. "Essentially, it transforms any machine into a codespaces equivalent." Where Daytona is actually starting in the enterprise is focusing on large dev environment solutions and management of those, and then trickling down to individual developers. So there are two very similar solutions to a problem of many developers and their varying ways that they set up their environments for development, but they're coming at it from two ends of the spectrum.

Bret and Nirmal are joined by Lukas Fittl of pganalyze to dive into Postgres in containers, in production, and in CI. Lukas is an expert and founder of pganalyze, and I invited him on the show to explain a lot of this to us and catch us up with what's going on in the Postgres community, particularly when it comes to containers and production. We dive into everything around containers with Postgres, some of the new stuff going on in Postgres Land, including tuning and stuff I didn't even know about Postgres, including storing NoSQL data, vector databases for AI and more.

Bret and Nirmal are joined by Melissa McKay, Developer Advocate at JFrog and Docker Captain, to discuss the best and worst of 2023. We recorded this episode in December of 2023 where we talked through our favorite tools. Whether a DevOps oriented tool or not, it just might be the things we like to use on containers and in Cloud Native DevOps. This is a fun episode of three friends talking about what they love. And I sometimes I think these are the best shows because we didn't plan them out. I hope you enjoy listening to it as much as we did recording it.

Bret is joined by Matan Mishan & Roy Razon of Livecycle to discuss developer platforms and how to improve developer collaboration and speeding up feedback and previews. We talk about the various delays encountered in pull requests due to feedback processes, and how Lifecycle's tools aim to shorten this feedback loop in Docker Desktop, local CLI with Preevy, and automated CI workflows. I like how Lifecycle provides multiple locations and ways to get access to people in the preview environments that really lets you just fit the different parts of the tool into your workflow, as opposed to one way to do everything. It's great for getting feedback quickly during the PR process, rather than making people set up their own environments to test their changes. I also liked their ideas around how the feedback loops can be improved.

Bret and Nirmal are joined by Michael Irwin, DevRel at Docker, to talk about all the products and features Docker shipped in 2023, and what's coming in early 2024. Michael has been on this show many times as a Docker Captain and now as a Docker employee, and it's always great to dig into the details of the products with someone who's been using them for so many years as an end-user and now staff at Docker. Docker did some big things in 2023, but they also shipped some smaller features that we will help you catch up on in this episode.

Bret is joined by Alex Kretzschmar to talk about Tailscale, a universal VPN that connects teams, devices, and development environments for easy access to remote resources. Alex and I talk about projects he's worked on in containers over the years and then we quickly get into Tailscale and talking about why he joined the team there. Tailscale is one of those tools that's hard to put down. I've used it for years to connect my personal devices to my home server lab when I'm traveling or servers I might have on the internet that I run temporarily. It connects them all together in a seamless VPN. The product itself comes up a lot in our Discord server when people are talking about needing some secure remote access to something anywhere in the world. Tailscale keeps adding more and more features, I can't really keep up, so we had Alex on the show to talk about all the new stuff, including a client for Apple TV, which at first, I didn't quite understand why, but now it totally makes sense; and a Kubernetes operator that does some slick things around connecting engineers on their local machines to clusters. I found Alex at the Tailscale booth at KubeCon this year and invited him on the show to talk about this relatively new yet ubiquitous-feeling product.

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! 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.

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.

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.

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. Live recording of the complete show from August 24, 2023 is on YouTube (Ep. #231).

Bret is joined by Dan Garfield of CodeFresh to talk about growth of GitOps as a standard, growth of Argo, and more. Dan is the Co-founder and Chief Open Source Officer of Codefresh, a CI/CD platform powered by GitOps and Argo. He helped launch the GitOps Working Group and helped lead the creation of the Open GitOps principles. As an Argo Maintainer, Kubernaut, Google Developer Expert, he helps companies and individuals adopt Argo with GitOps and streamline their CI/CD. We take some great questions about how GitOps is different than just triggering deployments and other automation platforms.
