Stand Alone Training und Customer demo Cloud env. 4 devel. & CI

Latest response

Motivation
1.) I work for the public sector and there it is difficult to use customer presentations with internet use for security reasons.

2.) I am an agile (Scrum) JEE application developer / architect and would like to familiarize myself with software application development in the cloud environment. I have a RedHat developer license. The aim is to learn the basic current technologies for the creation and the first CI steps and, if necessary, to bring them closer to the customer. A standalone laptop (i7 8core, 16 GByte MM, 1 TByte SSD) with RHEL should be used for this.

Action
First I want to develop a minimal Java application and then expand it step by step (several different persistent instances, technical µService, dialog and automatic processing...). I would also like to get to know other stand containers.

The following components should be part of the technology stack:
• RHEL
• OpenShift
• PodMan
• IDE

Questions

  1. Is this possible in principle?
  2. If so, is there a Guide / CookBook to install the required components on the computer step by step?
    (Please indicate source!)
  3. Are there any instructions for implementing a 'Hello World!'?
  4. What further sources are there?
    (e.g. container catalogs etc.)
