Falco Logs Suspicious Events on Your K8s and Servers

Bret and his co-host, Matt, are joined by Jason Dellaluce and Luca Guerra from Sysdig to talk about Falco, a tool I recommend for production clusters and knowing about any bad behavior on your servers. 🙌 My next course is coming soon! I've opened the waitlist for those wanting to go deep in GitHub Actions for DevOps and AI automation. I'm thrilled to announce this course. The waitlist allows you to quickly sign up for some content updates, discounts, and more as I finish building the course. https://learn.bretfisher.com/waitlist🍾 Falco is a security tool I've mentioned multiple times on this show, because I mostly think that a low level security focused logging product is something that every production server needs. The ability to log unexpected events and behaviors on your Linux host is powerful and necessary to be able to audit what's really happening on your infrastructure outside of your app itself. Falco has been a CNCF incubating project for over four years, and I was immediately drawn to it in its early days, because it was container and Kubernetes aware and it could log and alert with default rules for everything, from someone starting a shell inside a container, to a bash history file being deleted, to a container trying to talk to the Kubernetes API. This episode will be useful for those of you new to tools like Falco and for those familiar with its basics, but also wanting to learn about newer features and use cases, which I did some learning on myself in this episode. Live recording of the complete show from April 6, 2023 is on YouTube (Ep. #210). ★Topics★Falco websiteFalco on CNCF You can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!

Open Source Codespaces with Daytona

Bret and Nirmal are joined by Ivan Burazin and Chad Metcalf to debut Daytona, an open source "codespaces equivalent." 🙌 My next course is coming soon! I've opened the waitlist for those wanting to go deep in GitHub Actions for DevOps and AI automation. I'm thrilled to announce this course. The waitlist allows you to quickly sign up for some content updates, discounts, and more as I finish building the course. https://learn.bretfisher.com/waitlist🍾 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.

Faster Docker Builds with Depot

Bret is joined by Kyle Galbraith and Jacob Gillespie, co-founders of Depot, to discuss their new solution to slow Docker builds. 🙌 My next course is coming soon! I've opened the waitlist for those wanting to go deep in GitHub Actions for DevOps and AI automation. I'm thrilled to announce this course. The waitlist allows you to quickly sign up for some content updates, discounts, and more as I finish building the course. https://learn.bretfisher.com/waitlist🍾 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.
