Learn to mitigate and manage threats to OpenShift container-based infrastructure

Red Hat Security: Securing Containers and OpenShift (DO425) is designed to help infrastructure administrators and security professionals learn to identity and mitigate threats to OpenShift container-based infrastructure. The curriculum also covers how to implement and manage secure architecture, policies, and procedures for modern containerized applications and software-defined networking.

This course is based on Red Hat®Enterprise Linux® 7.5, Red Hat® OpenShift® Container Platform 3.11, and Red Hat® Identity Manager 7.5.

You will learn about using secure and trusted container images, registries, and source code; managing network and storage isolation; implementing application single sign-on; and configuring appropriate security constraints and service role–based access control. You will also find out how existing core Linux technologies—such as namespaces, cgroups, seccomp, capabilities, and SELinux—provide a robust and mature host environment with strongly secure containers.

Course content summary

• Learn Linux multitenancy isolation and least-privilege technologies.
• Investigate trusted repositories, as well as signing and scanning images.

Design, build, and test OpenShift HA cluster

Red Hat OpenShift Administration II teaches you how to build robust clusters that provide high availability and the ability to run large numbers of applications. You will learn about OpenShift integration with datacenter infrastructure such as load balancers, identity management, monitoring, proxies, and storage. You will also develop more troubleshooting and Day 2 operations skills in this course.

This course is based on Red Hat® OpenShift Container Platform 4.10.

You will design an OpenShift HA cluster, then build and test it. You will use this cluster to examine more advanced topics in the administration and operation of a robust OpenShift cluster in the remainder of the course.

Course content summary

• Understand container and OpenShift architecture.
• Create containerized services.
• Manage containers and container images.
• Create custom container images.
• Deploy containerized applications on Red Hat OpenShift.
• Deploy multi-container applications.
