Content 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

Agenda

  • In this course we will learn the capabilities and benefits of zCX.
  • 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
  • Exercises and recorded demos reinforce the concepts and technologies being covered in the lectures.

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
