For some time I’ve been hearing about Helm and have been asked by people how they could deploy into OpenShift applications defined as Charts, the format Helm uses to package an application. One of the really nice features that minishift >= 1.2.0 introduced was the concept of an addon which is a way to provide additional capabilities to your minishift local environment. As this feature is really interesting, and evolving really nicely, I have developed some addons that allow me to extend my minishift capabilities by issuing a single command.

One of my biggest interests is how to make local development experience with OpenShift as easy as possible. I’m constantly exploring what needs to be enhanced to our current experience as I develop applications for OpenShift very frequently. I work hard to understand developers requirements and eventually provide solutions in the tooling we provide. I use to incubate ideas in a project my team owns, oc-cluster-wrapper. I work very close with our engineering teams to solve these use cases in “oc cluster” or “minishift” depending on the nature of the problem, as even if they both can stand up an OpenShift all-in-one instance for local development, they both have different goals.

OpenShift provides different options for building and deploying containers on the platform. These generally include: Build and deploy from application source code - Users can specify the location of their source code in a GIT repository. OpenShift will build the application binaries, then build the container images that include those binaries and deploy to OpenShift. Users can also specify a dockerfile as the source code to build container images from.

We finally get to the last post of the series, and in this post I will introduce you to the tool that Developers will be using soon. It’s still not final and yet many features need to be planned and included, but will overcome all the problems I described in my previous posts. There’s already a good blog post from Lalatendu Mohanty about what CDKv3 is so I will not go into many details.

At the time OpenShift started, we realized that having a local development environment was important to make iterative development work more agile. Back then, the requirements that we had for a local development environment were pretty clear: It needs to work on linux, mac and windows It needs to be easy to run It needs to be easily disposable Resources used need to be adjustable
