Preliminary Exam In Containers, Kubernetes, & Openshift (Pe180)

The Preliminary Exam in Containers, Kubernetes, & OpenShift Exam (PE180) allows you to test and demonstrate the knowledge, skills, and abilities required to: 

• Implement new container images by extending existing images. 
• Manage images, including pulling and pushing images from a private registry. 
• Manually run and link containers in a development environment. 
• This exam is based on Podman and Red Hat® OpenShift® Container Platform 

• Administrators, architects, software developers, and anyone responsible for creating, managing, or using containers, including those who want to demonstrate their understanding of the key concepts and processes underlying the use of containers in modern software. 

Red Hat encourages you to consider taking Introduction to Containers, Kubernetes, and Red Hat OpenShift (DO180) to help prepare. 

This hands-on, practical exam requires you to undertake real-world tasks. Internet access is not provided and will be strictly controlled during the exam, and you will not be permitted to use any hard copy or electronic documentation during the exam. This prohibition includes notes, books, or any other materials, but documentation that ships with Podman is available during the exam.
