Short Summary


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

 

Overview


• 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.
 

 

Topic


– 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.
