Course description

Supporting the infrastructure for adoption of container technology and container-native applications, Kubernetes, and DevOps practices

The Container Adoption Boot Camp for Administrators (DO700) immerses you in intensive, hands-on management of container-native applications deployed on Red Hat's implementation of Kubernetes, Red Hat® OpenShift® Container Platform, at enterprise scale. This course is for those seeking to make a quantum leap in their digital transformation journey. Making this shift requires the ability to support a growing number of clusters, stakeholders, applications, and users to achieve large-scale deployments. As part of enrollment, you will receive one year of Red Hat Learning Subscription Standard, which gives you unlimited access to all of our courses online, plus up to five certification exams and two retakes.

This collection of courses is based on Red Hat OpenShift Container Platform 4.10.

Impact on the organization

• This Bootcamp is intended to provide container-novice administrators with the foundational and advanced skills needed to configure, manage, and automate the Red Hat OpenShift Container Platform to deploy containerized applications that are highly available, resilient, and scalable. Red Hat OpenShift Container Platform enables rapid application development and deployment, as well as portability of an application across environments. The platform also offers simplified application scaling, administration, and maintenance of adapted or cloud-native applications.

Impact on the individual

As a result of attending this course, you should be able to configure and manage a Red Hat OpenShift Container Platform 4 clusters at scale, including:

• Configure security controls for users, applications, and networking.
• Integrate OpenShift with enterprise authentication, storage, CI/CD, and GitOps systems to improve productivity of IT operations and compliance with organization’s standards.
• Troubleshoot techniques to identify issues with containerized applications, cluster operators and compute capacity.
