Interviews and Q&A from my weekly YouTube Live show. Topics cover Docker and container tools like Kubernetes, Swarm, Cloud Native development, Cloud tech, DevOps, GitOps, DevSecOps, and the full software lifecycle supply chain. Full YouTube shows and more info available at https://podcast.bretfisher.com
This is a special episode just for the podcast, where I detail the direction shift of docker's new features and how they are using the docker CLI to deploy to cloud's directly without needing to manage the Docker Engine.
I'm joined by Phil Estes of IBM, Distinguished Engineer & CTO for Container and Linux Architecture Strategy at IBM Cloud. He's a maintainer on the containerd CNCF project, and we're talking about containerd, which fuels Docker Engine and many Kubernetes container runtimes.
I chat with Docker Captain Nirmal Mehta of Booz Allen Hamilton about Kubernetes Ingress controllers and resources. There seems to be a lot of confusion around them, the different choices, and what to do for incoming HTTP connections in Kubernetes.
I have a live Q&A with Alex Ellis as we break down FaaS, Serverless, and how these technologies work with Docker and Kubernetes including his open source tools like OpenFaaS, Inlets, faasd, k3sup, and more.
I answer some audience questions about serverless, and the future of containers... when a lot of the news out there is talking about functions as a service is "the future of everything". As usual, the answer is "it depends", but if you're a team that's already doing microservices and containers, and you're looking to deploy smaller features faster and cheaper, then serverless might help. For most of us though, writing and shipping functions only, rather than traditional applications, is years away, because we have bigger problems to solve first, like speeding up our deployment processes or improving our monitoring and recovery.
In this episode, I sit down with Gerald Croes of Containous from KubeCon. We talk about the release of Traefik 2.0, and other projects like their new Service Mesh offering on top of Traefik called Maesh.
Happy New Year container fans! In this episode, I talk with Brice Fernandes of WeaveWorks to discuss their latest Kubernetes and Docker projects. We also talk about GitOps, which is my favorite way to setup application deployments and infrastructure changes.
In this episode, I traveled to Vienna, Austria and hung out with my friend Laura Tacho, and we talked about the human side of DevOps. We challenged ourselves to not mention any specific tools, but...that didnt last very long.
In this episode, I chat with a powerhouse combo of Kelsey Hightower and Jérôme Petazzoni, who's combined influence in the container space can not be overstated. I was a bit nervous for this one, having such big stars on the show n' all, but I think it went great as we dove into various Kubernetes and container topics. This is surely "one for the books"!
In this episode, I talk with Elton Stoneman, an Architect at Docker. We talk about Everything Docker and Windows, covering topics like WSL, Windows containers, Docker on Windows Server, and more.

Just last week we launched Kubernetes Mastery, which lets you dive into hands-on with the leading container orchestrator. I built this new course with my friend Jérôme Petazzoni, who's been teaching Kubernetes and Docker longer than almost anyone.

In this 50th episode, I sit down with two people from Cloudbees, Viktor Farcic, and Oscar Medina. We talk about CI/CD in Kubernetes and the GitOps-style of continuous deployment using Jenkins X.

In this special episode, just a day after Docker announces they've split the company and sold their Enterprise products, I sit down with fellow Docker Captians Jeff Nickoloff, Michael Irwin, and Nirmal Mehta to discuss it, as well as the future of Docker's open source.

In this episode, I talk about proxying with NGINX vs. Traefik, and the proper protocol for image tagging in a CI environment. I give a quick "elevator pitch" on Kubernetes, and I talk about service meshes like Istio. I also cover adding a conditional healthcheck to delay a service startup until another service is healthy.
In this episode, I have a great chat with Darren Shepherd, who is the Co-founder and Chief Architect at Rancher Labs. You probably know them for making, well, Rancher. We also talk about k3s, k3OS, RancherOS, RIO and k3v. It was a lot of fun and we covered a lot of ground on how they've launched so many Kubernetes projects in the last few years.
In this episode from my YouTube Live show, I talk more about Swarm and Kubernetes for Container Orchestration, and how I believe you should learn both. I answer questions from my Live YouTube audience and share some pros and cons of using each of the orchestrators. I recently updated my Docker Mastery course to include Kubernetes, so now you can get the best training on docker, compose, swarm, and kubernetes in a single course. Docker Mastery now includes over 15 hours of video. You can get discount coupons for all my courses at bret.show/courses. that's bret.show/courses. Thanks for listening, Now on with the show.
In this episode I talk with the authors of the book Docker In Action, 2nd Edition. We have a great chat on real-world craziness in running software and challenges with containers. It was a lot of fun, and I've put their book discount code in the show notes.
In this episode I'm live from the show floor at DockerCon with Nirmal Mehta and Nils De Moor as we cover the announcments, our favorite sessions, and take your questions on everything from Kubernetes, K3s, Proxy's, Traefik, Docker Enterprise 3.0, Linkerd, storage replication, and more.
In this episode, I have guests Nirmal Mehta, a Chief Technologist at Booz Allen Hamilton, and Michael Irwin, an Application Architect at Virginia Tech University. We talk about running tech meetups, how to be a community leader, the Docker and ARM announcement (the processor in Raspberry Pi), Docker for Node.js, AWS ARM A1 instances, QEMU, Traefik Proxies, Docker Swarm, Network Time (NTP, SNTP), Let's Encrypt, and more.
In this episode, I am joined by Phil Estes of IBM, Scott Coulton of Microsoft, and Sujay Pillai. We're all working in the DevOps space and discuss topics and open source projects weeks before DockerCon. Topics include Kubernetes, CNCF, ContainerD, CNAB, Rootless Docker, Linux security in containers, and more.
In this episode, I chat with Laura Tacho from CloudBees and Marcos Lilljedahl from iúnigo, both Docker Captains and developers. We take questions from the live audience and discuss topics ranging from the difference between Jenkins and Jenkins X, to Facebook's osquery and other new open source, to Docker's upcoming 19.03 release and its new features.
I answer a question about how to build multiple Docker images from a single GitHub repository. I talk about how to change which Dockerfile Docker build will use, and how to control the path (or context) that Docker builds from.
I answer a question about using TLS/SSL certificates in local development with Docker for microservices and then how to use those certs in production Docker. I talk about Let's Encrypt, Traefik, and more.
In March of 2019 I talked with Michael about the new "docker-app" experimental tool. This clip talks about why it exists, and how to use it. In April 2019 Docker released a beta of 19.03 that includes "docker-app" as a plugin to the standard docker CLI, as "docker app", but most other features of this tool stay the same. We also talk about the standard behind this tool, CNAB.
In Docker 18.09.1 and Docker Desktop 22.214.171.124 (stable) in January 2019, we now have a new option for running Windows Containers on Windows 10 in "process isolation mode" which removes the need to launch a full Windows Server Hyper-V VM. It's a great new way for running lightweight Windows Containers, but has its own limits and config requirements.
A viewer asks how they can prototype their software in Docker with a Raspberry Pi. I explain the various parts of the workflow including ARM 64 vs. x64 CPU architectures, the benefits of QEMU emulation in Docker Desktop, and how to get Docker images from your local machine to the Pi.
A viewer asks why their Elasticsearch server on their local development setup with Docker Compose would give them a yellow health status. I talk about the common causes for this in my own experience with shard replication.
A viewer asks about how their local docker container IP's, if behind NAT, can have issues with outside subnets at their company. I explain some of the ways even NAT won't solve IP routing for containers and how you can change your settings to different private subnets.
Someone asks about image pruning while a Swarm service is in the middle of deployment, and how they've experienced failed containers. I reply with the details of what's going on in specific steps of a Service creation and deployment, and how the prune command could interfere.
