Topic: System Administration
Sander van Vugt

Containers have become the standard for offering applications in the cloud and on servers. Red Hat is a leading provider of containers, offering their own podman-based solution for containers, as well as Kubernetes-based orchestration in OpenShift. This training will give you the skills you need to start implementing Red Hat’s solution as well as prepare you for the Red Hat Certified Specialist in Containers and Kubernetes EX180 exam.

What you'll learn-and how you can apply it

  • Running Containers with podman
  • Managing podman images
  • Installing an OpenShift POC environment based on Code Ready Containers
  • Understanding OpenShift
  • Creating applications in OpenShift
  • Troubleshooting applications in OpenShift
  • Using Source to Image to build container images straight from code

This training course is for you because...

  • It provides an introduction to working with podman containers and OpenShift, which can be used as one of the key ingredients in a hybrid cloud environment
  • It prepares for the Red Hat Certified Specialist in Containers and Kubernetes EX180 exam

Prerequisites

  • Working knowledge of Linux is required, preferably at RHCSA level

Course Setup:

To be able to build code ready container-based course setup environment, participants should install a recent Fedora Workstation, CentOS 8.x or RHEL 8.x virtual machine that meets the following requirements:

  • 12 GB RAM
  • 4 vCPU's with hypervisor extensions enabled to allow for nested virtualization. If you are using Mac OS Big Sur, verify that nested virtualization is working before start of the class
  • 60 GB disk space
  • Code Ready Containers software and pull secret downloaded to this virtual machine
  • The Code Ready Containers software can be obtained through developers.redhat.com.

Recommended Preparation:

  • If an attendee has no experience with Linux, it helps to first watch Linux Fundamentals (video)
