Course Description

• z/OS Container Extensions (zCX), a new entitled capability of z/OS 2.4, ushers in a new era of
hybrid computing supporting running Linux applications directly on z/OS.
 

• IBM® z/OS® Container Extensions (IBM zCX) makes it possible to run Linux on IBM Z®
applications that are packaged as Docker container images on z/OS. Application developers can
develop and data centers can operate popular open source packages, Linux applications, IBM
software, and third-party software together with z/OS applications and data.

Objectives

Describe the components of z/OS Container Extensions (zCX)- Plan the resources required to setup zCX- Configure and implement a zCX instance with z/OSMF workflow- Start and connect to your zCX instance- Access your zCX CLI Container and issue Docker commands- Provision and deploy application container using zCX docker CLI- Create Docker volumes for data persistence- Monitor and manage your zCX instance and your containers- Deploy some use-case applications in zCX containers- Understand the Security considerations for zCX and containers- Setup zCX user management and authentication- Implement clustering and orchestration of zCX instances and container- Understand how to to Dockerize your Applications for z/OS Container Extensions- Implement a zCX private secure registry to deploy your own containers- Position zCX in the world of Hybrid Cloud- Select workloads for zCX- Determine which application is a good fit for zCX- Describe some zCX use-cases

Audience

• This class is intended for z/OS system programmers and IT specialists in charge of configuring, implementing and deploying zCX under z/OS 2.4
• This class is also intended for Application developers who will deploy docker containers in a zCX z/OS container extensions instance

Prerequisites

• General z/OS knowledge, including basic UNIX System Services skills
• Basic knowledge of RACF
• Basic knowledge of z/OSMF and workflowsTBD

Content

• - You will plan, configure and implement a zCX instance with z/OSMF workflows
• - You will learn how to use z/OSMF to setup and configure zCX
• - Create, provisioning, and deploying a zCX instance
• - Use z/OSMF workflows to manage the lifecycle of a zCX instance, deprovision a zCX instance
• - Use reconfiguration workflow to increase/decrease resources for zCX instance
• - Using zCX Command Line Interface, you will
• - Get familiar with the docker CLI
• - Explore installing zCX containers within newly provisioned zCX instance
• - provision and deploy application containers using zCX docker CLI commands
• - Explore how to cluster zCX applications for higher availability and load balancing
• - Operationally control zCX
• - Dockerize your Applications for z/OS Container Extensions
• - Create Docker volumes for data persistence, monitor and manage your zCX instance and containers
• - Implement a zCX private secure registry to deploy your own containers
