ASP.NET Core 6 Blazor App Workshop - Instructor Prep Readme

These are the instructor notes for giving a hands-on workshop specifically for .NET developers doing cloud native development on OpenShift. OpenShift tends to have lots of enablement material around Java, Go, Python, and Ruby but not so much for .Net; even though it is a first class citizen on the platform. Microsoft has done a great job around making .Net Core 5 and after being cross platform and Linux friendly. The development experience using .NET with its live reloading makes it wonderful to use and being able to get that same experience even though the application is running on OpenShift and not a developer's local laptop is a critical part of cloud native development. Being able to utilize the resources of the cloud for development and for cloud deployment, but not sacrificing on the development experience is essential.

These notes are for an instructor that wants to prepare and run this workshop. This workshop gives developers first ha

Web Terminal Operator Readme

This is a really cool feature available within OpenShift that allows users to be able to use the Web Console and quickly pop open a terminal for those times when just typing the command is easier than finding the corresponding buttons in the browser.

For a quick brief intro, read this.

New App

For most oc commands, this works beautifully. There was one use case we ran into at our customer site where they wanted to hit their self-hosted GitHub repository when running oc new-app. Of course, their enterprise had their own certificate bundle that needed to be trusted.

Typically, within OpenShift, you would do something like this, which we did, however that did not work with this terminal pod.
