Learn to build and manage container images, administrate an OpenShift cluster, and troubleshoot applications running on Kubernetes
Containers, Kubernetes, and Red Hat OpenShift Administration II with exam (DO286) helps you gain core knowledge in building and in configuring and managing Red Hat® OpenShift® Container Platform. This immersive and intensive, hands-on course shows you how to deploy applications to a local container engines and OpenShift clusters, manage the cluster on a day-to-day basis, and troubleshoot the deployment of containerized applications.
Describe how applications run in containers orchestrated by Red Hat OpenShift Container Platform.
Create containerized services
Provision a service using container technology.
Modify prebuilt container images to create and manage containerized services.
Manage container images
Manage the life cycle of a container image from creation to deletion.
Create custom container images
Design and code a Dockerfile to build a custom container image.
Deploy containerized applications on OpenShift
Use OpenShift Container Platform to deploy single container applications.
Deploy multicontainer applications
Deploy applications that are containerized using multiple container images.
Explore Red Hat OpenShift Container Platform
Describe the architecture of OpenShift Container Platform.
Verify the health of a cluster
Describe OpenShift installation methods and verify the health of a newly installed cluster.
Configure authentication and authorization
Configure authentication with the HTPasswd identity provider and assign roles to users and groups.
Configuring application security
Restrict permissions of applications using security context constraints and protect access credentials using secrets.
Configure OpenShift networking for applications
Troubleshoot OpenShift software-defined networking (SDN) and configure network policies.
Control pod scheduling
Control the nodes on which a pod runs.
Scale an OpenShift cluster
Control the size of an OpenShift cluster.
Describe cluster updates
Describe how to perform a cluster update.

Note: Course outline is subject to change with technology advances and as the nature of the underlying job evolves. For questions or confirmation on a specific objective or topic, contact one of our Red Hatters.
Impact on the organization
This course provides novice administrators with the essential skills to configure and manage Red Hat OpenShift Container Platform clusters to support containerized applications that are highly available, resilient, and scalable. Red Hat OpenShift Container Platform is an enterprise, hardened distribution of Kubernetes that enables rapid application development and deployment, as well as portability of applications and operational processes across cloud providers and traditional data centers.
Impact on the individual
After completing this course, you should be able to demonstrate the skills necessary to execute and build local containers, establish the health of a new OpenShift cluster, grant users and developers access to the cluster, and manage the cluster on a day-to-day basis. One major focus of the course is troubleshooting common problems that will be encountered beyond day one as users and applications use cluster resources.
