This entry was posted in Containers Docker kubernetes and tagged blue-green deployments canary deployments cronjobs deployments kubectl monitoring rolling updates troubleshooting YAML on by

I’m excited to announce the release of my next course on Pluralsight titled Kubernetes for Developers: Deploying Your Code! This course is the next in the Kubernetes for Developers learning path and focuses on different techniques that can be used to deploy your containerized applications to Kubernetes. It follows the Kubernetes for Developers: Core Concepts course. Here’s the recommended order for taking my courses that cover containers and Kubernetes: Docker for Web Developers Kubernetes for Developers: Core Concepts Kubernetes for Developers: Deploying Your Code Here are a few questions this course will help you answer: What is a Kubernetes Deployment […]

Using the Kubernetes JavaScript Client Library

This entry was posted in javascript kubernetes Node.js TypeScript and tagged deployments services on by

I’ve been working with Kubernetes a lot and focusing on various deployment techniques that can be used (such as Blue-Green Deployments) for a Pluralsight course I’m creating called Kubernetes for Developers: Deploying Your Code. If you’re new to Blue-Green Deployments, here’s a quick overview: While I was working on the course, Dr. Christian Geuer-Pollmann and I had chatted on Twitter about a Blue-Green dashboard he wrote. He did a great job on it! I’ve been wanting to experiment with the JavaScript Kubernetes Client library so I decided to see what could be done to create a simple Blue-Green Deployment “dashboard” […]

Enabling Metrics Server for Kubernetes on Docker Desktop

This entry was posted in Docker kubernetes and tagged docker kubernetes metricsserver on by

Lately we’ve been working on a new Docker and Kubernetes instructor-led training class that we’ll be running onsite at several companies this year. The class uses Docker Desktop and the Kubernetes features it provides for several of the chapters. We needed to get the local cluster students will use to match as closely as possible to a cloud-based Kubernetes cluster that would be found on Azure, AWS, or GCP. The class covers using AKS as well, but most of the lab exercises rely on Kubernetes in Docker Desktop so running key features like the dashboard and Metrics API was important. […]

New Pluralsight Course – Kubernetes for Developers: Core Concepts

I’m excited to announce the release of my next course on Pluralsight titled Kubernetes for Developers: Core Concepts! Since creating the Docker for Web Developers course I’ve been wanting to create a course that takes developers to the “next level” with containers and the new Kubernetes for Developers course does that! Here are a few questions this course will help you answer: Why should I learn about Kubernetes if I’m a developer? What are the core concepts that I should know about to get started? How can I get Kubernetes running on my development machine? What is the role of […]

Deploying Your Angular Apps (using containers) – ngVikings Talk

This entry was posted in Angular Docker kubernetes and tagged containers deployment microservices on by

I had the opportunity to attend and speak at ngVikings this year in Copenhagen, Denmark which was a lot of fun. Copenhagen is a beautiful city and the conference organizers did a great job putting the event together. One of the talks I gave at the conference covered deploying Angular applications using containers. While the focus was on Angular and any services it may call, the concepts can really be applied to any front-end back-end application or service. Topics covered in the talk include: Deployment Challenges What is Docker? Images and Containers Orchestration with Docker Compose Orchestration with Kubernetes (introductory […]

Docker for Web Developers – Now with Kubernetes!

This entry was posted in Docker kubernetes and tagged course training video on by

Over the past year I’ve done several big updates to my Docker for Web Developers course on Pluralsight that I wanted to mention. First, all of the code samples have been updated and Docker Desktop (formerly called Community Edition) is now covered in addition to Docker Toolbox. The biggest update came when I added a new module into the course titled “Moving to Kubernetes”. This module provides an overview of Kubernetes and what it is (a very exciting technology!), examples of using key Kubernetes commands, and an example of moving the Docker Compose orchestrated application shown in the course to […]

4 kubectl Commands to Help Debug Pod Issues in Kubernetes

This entry was posted in Docker kubernetes and tagged commands containers debug diagnose kubectl pods on by

If you’ve worked with containers a lot you’re probably good at commands like docker logs and docker exec to retrieve information about containers that may be having problems. One of the challenges that comes up as people move to Kubernetes is understanding how to get similar details about Pods and any containers running within them. I’ve had several people ask me about this recently in my instructor-led Kubernetes course as well as online with my Docker for Web Developers course (which has a module on Kubernetes) so I decided to post a few of the initial commands you can use […]

CloudSkills Podcast Interview: Docker, Kubernetes, and Microservices

This entry was posted in Containers Docker kubernetes microservices and tagged containers docker kubernetes microservices podcast on by

I recently chatted with my friend Mike Pfieffer who runs the CloudSkills.fm podcast about Docker, Kubernetes, and Microservices. Mike works a lot in the DevOps space and I work in the developer space (and do some DevOps as well) so it was a fun discussion about challenges that come up in both worlds. We discussed the benefits of containers, the role of Kubernetes, and how both can play an important role when working with Microservices.
