Course description

Deploy, manage, and troubleshoot containerized applications running as Kubernetes workloads in OpenShift clusters.

• Red Hat OpenShift Administration I: Managing Containers and Kubernetes (DO180) prepares OpenShift Cluster Administrators to perform day-to-day management of Kubernetes workloads and collaborate with Developers, DevOps Engineers, System Administrators, and SREs to ensure the availability of application workloads. This course focuses on managing typical end-user applications that are often accessible from a web or mobile UI and represent the majority of cloud native and containerized workloads. Management of applications also includes deployment and updating of their dependencies such as databases, messaging, and authentication systems.
  
  The skills you learn in this course can be applied using all versions of OpenShift, including Red Hat OpenShift on AWS (ROSA), Azure Red Hat OpenShift (ARO), and OpenShift Container Platform.
  
  This course is based on Red Hat^® OpenShift^® 4.14.
• Following course completion, you will receive a 45-day extended access to hands-on labs for any course that includes a virtual environment.

Course content summary

• Managing OpenShift clusters from the command-line interface and from the web console.
• Troubleshooting network connectivity between applications inside and outside of an OpenShift cluster.
• Connecting Kubernetes workloads to storage for application data.
• Configuring Kubernetes workloads for high availability and reliability.
• Managing updates to container images, settings, and Kubernetes manifests of an application.

Audience for this course

• System Administrators and Platform Operators interested in the ongoing management of OpenShift clusters and containerized applications.
• Site Reliability Engineers interested in the ongoing maintenance and troubleshooting of containerized applications on Kubernetes.
• System and Software Architects interested in understanding the features and functionality of an OpenShift cluster.

Prerequisites for this course

• Take our free assessment to gauge whether this offering is the best fit for your skills.
• Prerequisite: Containers, Kubernetes and Red Hat OpenShift Technical Overview (DO080) or equivalent knowledge of Linux containers.

Configure and manage network infrastructure using Red Hat Ansible Automation for Networking

Ansible for Network Automation (DO457) is designed for network administrators or infrastructure automation engineers who want to use network automation to centrally manage the switches, routers, and other devices in the organization’s network infrastructure.

This course is based on Red Hat^® Ansible Engine 2.5 and Red Hat^® Ansible Tower 3.2.

Learn how to use Red Hat Ansible Automation for Networking to remotely automate configuration of network devices, test and validate the current network state, and perform compliance checks to detect and correct configuration drift.

Course summary

• Prepare a development environment for Ansible network automation
• Write and troubleshoot effective Ansible Playbooks for network automation
• Gather information about network infrastructure configuration for infrastructure awareness and configuration backup
• Automate specific network administration use cases, including configuration of routers and switches, ports, VLANs, SNMP monitoring, and routing protocols
• Use Ansible Playbooks to manage devices from various hardware vendors, including Cisco, Juniper, and Arista
• Centrally manage Ansible content in Git and run it centrally with automation controller
• Reuse existing, tested network automation code with Ansible Roles, Ansible Content Collections, and Ansible validated content

Target Audience

This course is designed for network administrators, network automation engineers, and infrastructure automation engineers who are responsible for deploying, managing, and automating the network infrastructure of their organization or enterprise.

Recommended Training
