Why should we care about containers for development

There has probably been more than one time in your development career where you've spent a few hours troubleshooting an issue only to find out it was a dependency or versions issue right? Environments varying from one to next, outdated components and setting up development machines are frustrations we can all do without. Some of these issues we've solved with VMs, but managing the entire machine and underutilizing them for each environment is costly. This is where containers have come to solve many challenges. Why Containers It's no doubt that you have heard the buzz about containers over the last year or longer. If not containers, then some technology, framework, or tooling associated with it; Docker, Kubernetes, microservices are just...


Workshop gets an update - JavaScript Services, Docker, Kubernetes and Helm!

If you've been to a conference around .NET in the last year or so, there's likely been workshop available from the .NET team. Jeff Fritz, Jon Galloway, Maria Naggaga, Damian Edwards and/or Daniel Roth and I have all presented in part some of the ConferencePlanner app. The workshop contains building an application from scratch in .NET Core using Razor Pages, Entity Framework, Web API. I spent some time over the last week updating the workshop to add options for using the updated JavaScriptServices and Deployment options with Docker, Kubernetes, and Helm. Adding JavaScript Services Adding Angular SPA using JavaScript Services Some great improvements have been made to the JavaScript Services for using Angular and React, integrating each frameworks' CLI...


Enabling Kubernetes Beta on Docker

Still think this is one of the best things to happen this year! @Docker + #Kubernetes pic.twitter.com/Bgk6fCbruW— Shayne Boyer (@spboyer) December 19, 2017 A few days ago the beta for Kubernetes was checked off for me and I rushed to the machine to get cracking on the new stuff. I've already been using Kubernetes on Azure for a few projects, but being able to run the projects locally is great, especially if I'm traveling or just testing stuff and don't want to push just yet. After enabling the K8s cluster locally, you need to set your kubectl to use the new cluster. I have a number of contexts set for the projects and wasn't sure what the...


Kompose - Docker-Compose to Kubernetes with ease!

I like to use Docker compose files for a couple of reasons. First, I have spent more time that I have in my vacation balance to understand the format. Second, they are great for local development even when I only have a single container, obfuscating the environment variables into a separate file and so on. Since moving to more and more Kubernetes development, and getting in tune with the file spec for deployments; converting the compose files by hand have been painful at times especially with the complicated ones where there are a ton of containers, networking and environment variables. Kompose to the rescue! Through a quick search and reading the docs at kubernetes.io, I came across kompose. kompose...


Introducing metaparticle.io - making Kubernetes and Docker idiomatic for developers

What if you could just add a package to your code? Like npm for node or nuget for .NET, run your app and have it in a container on a Kubernetes cluster? No command line tools like kubectl, helm, docker or whatever we are currently using to create our containerized apps today. Not these are bad, but it should be easier or native to how we are currently writing our apps. Metaparticle.io Metaparticle (metaparticale.io) is a new tool, in progress, announced at KubeCon from Brendan Burns and it's goal is to do just that, make it easier for devs to containerized their applications by just writing code.
