On the 14th of March, 2023, about 2% of Docker accounts received an email that our Docker Hub organizations were no longer eligible for the Free Plan, and that after April 14th, 2023, those orgs and all their repositories and images would be unavailable. That is, unless we upgraded to a paid plan for each organization, which would be a minimum of $300/year. To a lot of us in the open-source community, this was alarming. Much of that communication was misleading, but the good news is Docker released a better FAQ. Because it took 48 hours to release it, many people were (and still are) confused about if they are affected but, now, the FAQ is available. This podcast is a quick attempt at distilling all that down into the essentials, the gist of what you need to care about. If I'm incorrect on anything here, I will either edit this podcast or just add the update/change to the show notes so you'll see any edits in your podcast player. But if it's a big change, I will probably edit this podcast. So the theory is that if you're listening to this weeks, days, months later, this podcast actually should have the most up-to-date information. So let's dig in. (00:00) - Intro (00:54) - The initial email and fallout (04:39) - What Docker images does this actually affect? (08:15) - Can someone squat the name of deleted orgs? No. (08:42) - Will my downstream images built from deleted orgs still be usable? Yes. (10:24) - Options for owners of Hub organizations on the free plan (11:49) - Options for users (consumers)of Hub images that were on the Org free plan (12:41) - Going forward ★Topic Links★ Docker's blog post and FAQ on the Docker Hub org changes My Twitter thread of essential details as the come available Creators & Guests Bret Fisher - Host Beth Fisher - Producer Support this show and get exclusive benefits on Patreon, YouTube, or bretfisher.com! ★Join my Community★ New live course on CI automation and gitops deployments Best coupons for my Docker and Kubernetes courses Chat with us and fellow students on our Discord Server DevOps Fans Grab some merch at Bret's Loot Box Homepage bretfisher.com

Bret is joined by Kyle Galbraith and Jacob Gillespie, co-founders of Depot, to discuss their new solution to slow Docker builds. If you've never dug into some of the details of Dockers BuildKit, that's the engine behind your Docker build command, then this episode is for you. I'm fairly confident that everyone who uses Docker will eventually come upon the problems that Kyle and Jacob were trying to solve with Depot. Their focus is on speeding up your Docker builds by doing them remotely, in a transparent way. They avoid you needing to rethink your workflows and CI automations and provide a CLI tool that's a drop-in replacement for the Docker build command. In this episode, we walked through the problems they can solve today with what I would call a unified shared build cache for your whole team, including your CI and automation tools. The way they are going about speeding up the Docker builds is something I wished Docker had done for us all along. I think it's still early days for the Depot product, but if you're suffering with long build image times it's already mature enough to be something I would consider as a replacement for the traditional Docker engine builds that we're all used to.

Bret is joined by Natan Yellin, the co-founder of Robusta.dev to talk Kubernetes and Prometheus monitoring, alerting, and maybe some CPU limit ranting. Robusta tries to fill the gap left by Kubernetes' own AlertManager which has a very specific and not so helpful way of describing events in your cluster. This makes it hard to diagnose the cause of the event and you're left with Google, StackOverflow and an awful lot of head-scratching. Robusta acts as a proxy between AlertManager and your notification platform of choice. In the show we talk about what Robusta is, how to deploy it in your clusters, and Natan also details some of the enhancements in their cloud offering that you can layer on top of that, which has a generous free tier.

Bret is joined by two pros from the NGINX team, Robert Haynes and Brian Ehlert to break down the various use cases of NGINX on Kubernetes, and help you decide when and where you'll be using it. There's a lot going on around NGINX and I wanted to focus this conversation around NGINX on Kubernetes, and specifically the two ways you can run it for cluster ingress. We also get into some of the advanced scenarios of using NGINX, like caching and web application firewalls (WAF). Many of us are using NGINX somewhere in our clusters. I found it very interesting how Robert, Brian, and the team at F5 spend a lot of time showing customers how they can use it in many ways to avoid deploying additional products on their clusters. I'm a big fan of reducing complexity. Streamed live on YouTube on December 15, 2022.

Bret is joined by Matt Williams of Infra to show off their open source project Infra, which provides easy, centralized RBAC and auth to Kubernetes and more. Infra is a new company taking on simplifying centralized infrastructure, user authentication and permissions. Their open source tool by the same name is quite easy to start with. In this episode, Matt does a great job of explaining the pain points of Kubernetes user management, certificate distribution and revocation, and more pain points that Infra is bringing simplicity to.

Bret is joined by Anaïs Urlichs of Aqua Security to talk container and Kubernetes security tools like trivy, kube-bench, tracee, and kube-hunter. I've been using trivy for over four years to scan for known vulnerabilities in my own container images and my clients. We also look at tracee, a new tool that is part of a new generation of tools that use the Linux kernel eBPF feature to investigate what's happening in real time on your servers. Anaïs is great as an explainer of Kubernetes and all cloud native things, and she's the creator of the 100 days of Kubernetes tutorials on her YouTube channel where she breaks down various cloud native topics for beginners. Based on what I've learned in this show from Anaïs, I plan to change how I use trivy so that it's scanning more things and more often in my CI automation pipelines.

Bret is joined by two Chainguard co-founders, CEO Dan Lorenc and Head of Product, Kim Lewandowski, to break down the ins and outs of supply chain security and talk about Chainguard's approach to securing it. We dive into tools, including their new Wolfi Linux distro. We first talk about what that even is, because it's a buzzword right now, and not everyone's on the same page on what securing your supply chain even means in the world of software. Then we jump into base images for containers, and their project Wolfi. We talk a lot about Wolfi in this episode, because it has the potential to change how we build our containers.

Bret is joined by Liz Rice, Chief Open Source Officer at Isovalent, the makers of Cilium, to discuss Cilium and eBPF. Liz Rice is back to give us more insight into eBPF and the Cilium project. Isovalent is the company that created and manages the Cilium Project, which does an increasing number of things for Kubernetes, including networking, CNI support, security, advanced networking stuff, and observability, as well as other things like load balancing. Liz is one of my go-to experts on how low-level Linux internals work. She's been speaking about container internals since the early days of Docker. Streamed live on YouTube on September 8, 2022.

Bret is joined by Shauli Rozen, CEO and Co-Founder of ARMO, creators of Kubescape. Kubescape is a K8s open-source tool providing a multi-cloud K8s single pane of glass, including risk analysis, security compliance, RBAC visualizer, and image vulnerability scanning. I'm a fan of tools like this and specifically of Kubescape, which I use and recommend to my clients. The scanner can scan your YAML manifests of your Kubernetes resources. It can scan your live Kubernetes clusters. And it can scan the YAML in your Git repos, as well as the images themselves that you're deploying to Kubernetes. As ARMO calls it, it's a single pane of glass into your Kubernetes security. Streamed live on YouTube on September 1, 2022. Includes demos.

Bret is joined by Martin Wimpress and Pieter van Noordennen from Slim.ai to discuss some ways to slim down your Docker images and reduce the attack surface of your containers in the process. Many companies and projects have tried to do similar things before - Slim Images, Alpine Images, Distro List, Build Packs, and even Docker tried a few years back, to create intelligence and guidance around migrating legacy apps into slim production quality images. Those efforts were scrapped in 2019. The dual mandate of generating Docker images - easy to understand and as minimal as possible, with the lowest CVE vulnerability count - was not achieved by any of those projects. Automation and intelligence like Slim.ai is the future of building container images and also the future of complex monoliths and legacy apps with a lot of dependencies.

Bret is joined by Guillaume Tardif and Felipe Cruz of Docker Inc. for a deep dive into Docker extensions. Docker Extensions are a favorite new feature. Guillaume and Felipe are both engineers at Docker and they walk us through how extensions came about, how to install them, and how to submit them to the marketplace. By the time Docker released extensions at DockerCon in May 2022, there were already a dozen solid extensions, including a disk manager, log explorer, and other third-party tools like Portainer, Snyk, and Anchor. Docker extensions will be most helpful to people who use Docker Desktop. Streamed live on YouTube on June 16, 2022. Unedited live recording of this show on YouTube (Ep #174).

Bret is joined by Nirmal Mehta, a Principal Specialist Solution Architect at AWS, and a Docker Captain, to discuss Karpenter, an autoscaling solution launched by AWS in 2021. Karpenter simplifies Kubernetes infrastructure by automating node scaling up and down, giving you "the right nodes at the right time." Autoscaling, particularly for Kubernetes, can be quite a complex project when you first start. Bret and Nirmal discuss how Karpenter works, how it can help or complement your existing setup, and how autoscaling generally works. Streamed live on YouTube on June 9, 2022.
