Course Overview
The Developing Containerized Apps on OpenShift course teaches modern software development best practices commonly used to develop and deploy enterprise applications on Openshift. In this course, you will learn the fundamentals of containerized software development and how to use them in your application.
On day one, participants learn how to use container technology in application design and building. Day two includes an introduction to the key Kubernetes principles and paradigms on OpenShift and how to use and deploy applications on the platform. On day three, participants learn the fundamentals of software automation and modern best practices for cloud-native software development.
Optional: On the final day, attendees learn about the most advanced development concepts and principles that ensure software is robust, reliable, and ready to run.
All described topics are conceptually elucidated before being tested in the lab. Labs use Openshift as the target platform.

Course Content
Day 1 - Essentials:
- Container introduction
- Lab 1: Create a sample application and Containerize it.
- Image Repository introduction
- Lab 2: Push the sample application into a registry and get familiar with the concepts and its usage.
- Container best practises in a nutshell (security, users, ports, logging, exec, …)
- Infrastructure as Code (IaC) introduction
- YAML introduction for applying IaC
Day 2 - Introduction and Get in Touch with the Platform:
- OpenShift platform in a nutshell
- OpenShift architecture in a nutshell
- OpenShift CLI basics
- Lab 3: Get in touch with the CLI and use first commands to get information about the cluster and its state.
- Microservice basics
- Lab 4: Enhance the container deployment from day 1 and create a first microservice by yourself.
- Lab 5: Deploy the microservice in a semi-automated manner by using the CLI and a simplified YAML IaC definition.
Day 3 - Developing and Automation on the Platform:
- CI/CD Introduction and available tools in OpenShift
- Lab 6: Setup a first simplified CI/CD process
- Design a commonly used development process.
- Lab 7: Setup and configure the defined process on the platform.
