In this episode, Bret is joined by Portainer's co-founder and CEO, Neil Cresswell, to get an update on their product. If you haven't heard of Portainer, it's one of the original web apps to manage Docker, then swarm, and now Kubernetes.

How To

Bret and Nirmal are joined by Neil Cresswell and Steven Kang from Portainer to look at K2D, a new project that enables us to leverage Kubernetes tooling to manage Docker containers on tiny devices at the far edge. 
K2D stands for Kubernetes to Docker, which is a bit of a crazy idea -- it's a partial Kubernetes API running on top of Docker Engine without needing a full Kubernetes control plane. If you work with very small devices, including older Raspberry PIs, 32-bit machines, maybe industry sensors and the infrastructure we now call 'edge', the container hardware is often hard for you to make simple, reliable, and automated all at the same time.  So this project uses less resources than a single node K3S and still allows you to use Kubernetes tools to deploy and manage your containers, which are in fact just running on a Docker Engine with no full-fledged Kubernetes distribution going on there. We get into far more detail on the architecture, the Portainer team's motivations for this new open source project and what its limitations are, because it's not real Kubernetes, so it can't do everything. Be sure to check out the live recording of the complete show from March 28, 2024 on YouTube (Ep. 260). Includes demos. ★Topics★

K2D by Portainer

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.

Chainguard: Building Secure Container Images

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. Be sure to check out the live recording of the complete show from February 22, 2024 on YouTube (Ep. 255). ★Topics★

AWS Finch: The Minimal Local Container Solution

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. Be sure to check out the live recording of the complete show with demos from February 29, 2024 on YouTube (Ep. 256). ★Topics★

Portainer for Kubernetes, Docker, Swarm, Edge, and IoT

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.  Be sure to check out the live recording of the complete show with demos from March 7, 2024 on YouTube (Ep. 257). ★Topics★
