K2D by Portainer
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).

Chainguard: Building Secure Container Images
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 AnnouncementCreators & Guests Cristi Cotovan - Editor Beth Fisher - Producer Bret Fisher - Host Nirmal Mehta - Host Dan Lorenc - Guest (00:00) - Intro (05:14) - Dan's Take on the XZ Hack (14:59) - Chainguard Distro Creation (21:21) - Chainguard in Docker Hub Announcement (24:26) - Free Images vs Private Images (26:27) - Zero CVE Approach (28:33) - Ways to Reduce Attack Surfaces (39:56) - Chainguard Academy (41:08) - Real Time Antivirus Malware Scanner (43:52) - Google Distro Lists Worth Using (45:56) - Chainguard for Buildpacks (46:20) - SLSA (56:08) - What's Next for Chainguard?

AWS Finch: The Minimal Local Container Solution
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★Finch WebsiteBret's local container runtime spreadsheetCreators & Guests Phil Estes - Guest Cristi Cotovan - Editor Beth Fisher - Producer Bret Fisher - Host Nirmal Mehta - Host (00:00) - Intro (00:35) - What is Finch?

Open Source Codespaces with Daytona
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 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.

Faster Dev Feedback and Previews with Livecycle
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.This episode contains great demos so be sure to also check out the live recording of the complete show from December 21, 2023 on YouTube (Ep. #246). ★Topics★Livecycle's WebsitePreevy RepositoryLivecycle Docker ExtensionCreators & Guests Bret Fisher - Host Matan Mishan - Guest Roy Razon - Guest Beth Fisher - Producer Cristi Cotovan - Editor (00:00) - Intro (01:57) - Internal Developer Platform: a self-service solution (06:38) - Lifecycle and the Docker Extension (24:10) - Using GitHub Environments (27:46) - First Steps and What's Next You can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!Grab the best coupons for my Docker and Kubernetes courses.Join my cloud native DevOps community on Discord.Grab some merch at Bret's Loot BoxHomepage bretfisher.com

Tailscale Everything
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.  The live recording of the complete show from November 30, 2023 is on YouTube (Ep. #243)★Topics★Tailscale websiteHeadscale websiteTailscale CommunityTailscale Docker Mod Blog PostID Headers DemoDevrel DemoCreators & Guests Cristi Cotovan - Editor Beth Fisher - Producer Bret Fisher - Host Alex Kretzschmar - Guest (00:00) - Tailscale Everything (19:37) - Tailscale Licensing (28:24) - Tailscale vs Other Networking Products (32:33) - Server and Key Exchange (33:50) - Does Tailscale Support 'Trunking'?

Multipass Local Virtual Machines
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.Live recording of the complete show from September 21, 2023 is on YouTube (Ep. #235).

NetBackup for Kubernetes
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.The Live recording of the complete show from October 19, 2023 is on YouTube (Ep. #238).★Topics★Veritas Kubernetes solutionsInfoScale Free Developer Edition60 day–trial of Veritas InfoScale for KubernetesCreators & Guests Bret Fisher - Host Cristi Cotovan - Editor Beth Fisher - Producer Demetrius Malbrough - Guest Joseph D'Angelo - Guest You can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!Grab the best coupons for my Docker and Kubernetes courses.Join my cloud native DevOps community on Discord.Grab some merch at Bret's Loot BoxHomepage bretfisher.com (00:00) - Intro (01:15) - Introducing the guests (03:38) - The Evolution of NetBackup (07:45) - The NetBackup Pitch (10:52) - How is NetBackup Deployed?

AWS Lambda Containers
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.Live recording of the complete show from September 7, 2023 is on YouTube (Ep. #233).★Topics★Custom Ink tech blogRails and LambdaLambda Web AdapterLambda sidecar pattern in KubernetesThe case for Rails on LambdaLambda RAG OpenAILearn ServerlessCreators & Guests Bret Fisher - Host Cristi Cotovan - Editor Beth Fisher - Producer Ken Collins - Guest Nirmal Mehta - Host (00:00) - Intro (01:27) - What Does Lambda Have to Do with Containers?

Ephemeral & Preview Environments for Compose and Kubernetes
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).

OpenSauced with Brian Douglas
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.  Live recording of the complete show from July 13, 2023 is on YouTube (Ep. #225).★Topics★OpenSauced websiteBlog article: Good first issues don’t existYou can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!Grab the best coupons for my Docker and Kubernetes courses.Join my cloud native DevOps community on Discord.Grab some merch at Bret's Loot BoxHomepage bretfisher.comCreators & Guests Bret Fisher - Host Cristi Cotovan - Editor Beth Fisher - Producer Nirmal Mehta - Host Brian Douglas - Guest (00:00) - (00:52) - Introducing Brian Douglas (00:56) - What is OpenSauced?

Istio Ambient Mesh and Solo.io
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
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.Live recording of the complete show from June 15, 2023 is on YouTube (Ep. #221).★Topics★Ways to run containers on AzureDaprWebAssembly on Azure KubernetesWasmtimeTwelve-Factor AppYou can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!Grab the best coupons for my Docker and Kubernetes courses.Join my cloud native DevOps community on Discord.Grab some merch at Bret's Loot BoxHomepage bretfisher.comCreators & Guests Bret Fisher - Host Cristi Cotovan - Editor Beth Fisher - Producer Matt Williams - Host Brendan Burns - Guest (00:00) - Intro (03:10) - Introducing Brendan (08:47) - Advice for starting to run containers (30:30) - Reducing complexity with AI (34:41) - Addressing DevOps fatigue (42:38) - Running WebAssembly on Kubernetes (54:23) - LTS Linux Distributions (59:28) - What's next after containers and orchestration?

Kasten K10 Kubernetes Backups
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.

Cycle.io LowOps container platform
Bret and Matt welcome Jake Warner back to the show to talk about LowOps. What does LowOps mean? What can Cycle offer us as an alternative to Swarm and Kubernetes?Jake Warner is the CEO and founder of Cycle.io. And I had him on the show a few years ago when I first heard about Cycle and I wanted to get an update on their platform offering. On this show we generally talk about Docker and Kubernetes but I'm also interested in any container tooling that can help us deploy and manage container based applications. Cycles' platform is an alternative container orchestrator as a service. In fact, they go beyond what you would provide normally with a container orchestrator and they provide OS updates, networking, the container runtime, and the orchestrator all in a single offering as a way to reduce the complexity that we're typically faced with when we're deploying Kubernetes. While I'm a fan of Docker swarm due to its simplicity, it still requires you to manage the OS underneath, to configure networking sometimes, and the feature releases have slowed down in recent years. But I still have a soft spot for those solutions that are removing the grunt work of OS and update management and helping smaller teams get more work done. I think Cycle has the potential to do that for a lot of teams that aren't all in on the Kubernetes way, but still value the container abstraction as the way to deploy software to servers.Live recording of the complete show from May 18, 2023 is on YouTube (Ep. #217).

AWS containers with Corey Quinn
Bret and Matt are joined by Corey Quinn to talk about AWS and containers.Corey Quinn is the Chief Cloud Economist at the Duckbill Group. You may have seen or heard some of his in-depth AWS content, including his Last Week in AWS newsletter and blog, Corey's podcast Screaming in the Cloud and the AWS Morning Brief, or his highly produced YouTube videos on the Last Week in AWS channel. Corey runs the Duckbill Group, a company of people focused on helping clients understand and manage their cloud spend. If I had to describe Corey in a sentence, he's a quick thinking AWS expert who is one part cloud strategist, and one part sarcasm. The inspiration for this show came from his blog series, focused on all the ways to run containers on AWS, which is to say there's a lot. Dozens of ways, in fact, which I took as a testament to how containers have won the cloud as the primary way to package and deploy software to servers. Now, the hard part for us is to figure out which method we're going to choose for running those containers. We go on lots of tangents, but overall it was a fun conversation and I hope you enjoy this episode.Live recording of the complete show from May 4, 2023 is on YouTube (Ep. #214).★Topics★The Cloud Resume ChallengeLast Week in AWS17 ways to run containers on AWS17 MORE ways to run containers on AWSYou can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!Grab the best coupons for my Docker and Kubernetes courses.Join my cloud native DevOps community on Discord.Grab some merch at Bret's Loot BoxHomepage bretfisher.comCreators & Guests Bret Fisher - Host Cristi Cotovan - Editor Beth Fisher - Producer Matt Williams - Host Corey Quinn - Guest (00:00) - Intro (07:19) - 17 Ways to Run Containers on AWS (09:57) - If you're using the cloud, use the cloud!

Podman In Action: Desktop, Machine, and more
Bret and Matt are joined by Brent Baude and Dan Walsh from Red Hat to talk about the latest with Podman, Quadlet, Podman Desktop and Podman machine, and how it all works with Kubernetes.Dan Walsh, a Senior Distinguished Engineer at Red Hat, has been working with containers since the beginning. He's a contributor to Docker, Project Atomic, SELinux, and a lot more. He literally wrote the book on Podman. Brent Baude, is a Senior Principal Software Engineer at Red Hat and an architect and a primary maintainer of Podman, and contributes to many of its associated technologies like CRI-O, Buildah, and Skopeo. We go through a lot of tooling in this episode because Red Hat has taken a different stance than Docker in how it delivers its container tooling. You might say they take the approach of the Unix philosophy of every program does one thing well. Most of us know Docker and how it bundles many things related to containers into a single command line and daemon, yet some would prefer to isolate pieces of container management functionality into discreet, smaller programs - one for building images, one for running containers, one for communicating with registries, one for adding a GUI to your container manager, and one for managing the container VM. It's just sort of how I would break down the Podman ecosystem.And while that may seem like a lot of things, it's basically what Docker does for you in a single tool, yet the isolation of these tools is what can make them purpose-fit when you only need a fraction of the functionality of Docker. For example, one of Podman's core tenants is that it tells systemd to run your pods, which is the initialization process on most Linux distributions. In this way, your containers become more like standard system processes, rather than the Docker way of running all containers under the Docker Daemon process itself. Now many of us have heard of the other two original Red Hat container projects, Skopeo and Buildah, but there's now an increasing number of things the Podman ecosystem can do. So I'm grateful to Dan and Brent for coming on to break down the new parts of this toolkit and how we might use them.Live recording of the complete show from April 20, 2023 is on YouTube (Ep. #212).★Topics★Podman WebsitePodman Desktop WebsiteDan Walsh's book, Podman in ActionPodman Machine referenceQuadlet Blog PostPodman and Quadlet Blog PostYou can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!Grab the best coupons for my Docker and Kubernetes courses.Join my cloud native DevOps community on Discord.Grab some merch at Bret's Loot BoxHomepage bretfisher.comCreators & Guests Bret Fisher - Host Cristi Cotovan - Editor Beth Fisher - Producer Matt Williams - Host Brent Baude - Guest Dan Walsh - Guest (00:00) - Intro (04:26) - Dan's history with containers (10:52) - The recommended way to get Podman (11:55) - Podman Machine (13:27) - How is Podman Machine installed (16:43) - How is Podman organised (19:22) - Podman Compose explained (25:21) - Podman Desktop (28:52) - Podman and Docker extensions (30:16) - Support for Kubernetes YAML (36:54) - Podman and systemd workloads (42:44) - How to get started with Podman (51:38) - Overlaying networks with Podman

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. 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 CNCFYou can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!Grab the best coupons for my Docker and Kubernetes courses.Join my cloud native DevOps community on Discord.Grab some merch at Bret's Loot BoxHomepage bretfisher.comCreators & Guests Bret Fisher - Host Cristi Cotovan - Editor Beth Fisher - Producer Matt Williams - Host Jason Dellaluce - Guest Luca Guerra - Guest (00:00) - Intro (02:24) - Introducing the guests (05:25) - What is Falco?

DevPod for Dev Containers
Bret is joined by Lukas Gentele and Rich Burroughs from Loft Labs to look at a new project called DevPod, that supports dev containers and VMs. It works with local Docker instances and AWS, GCP, Azure, and several other cloud providers. The project is compatible with Microsoft's DevContainer standard, which means it works with the VC Code standalone app and VS Code in the browser.Lukas and Rich were on this show last year, showing off vcluster, which allows you to run a full Kubernetes cluster inside an existing Kubernetes namespace. In this episode, we announce the release of DevPod and also go through some demos.
