Setting Up Multi-Container Applications in OpenShift

For this lab, we will be creating an application that has multiple containers. You will learn to work with templates to create a multi-container application. Due to limitations in the A Cloud Guru Cloud Playground environment, we are unable to provide a hands-on experience for this lab. 1. To complete this lab, you must first register for a Red Hat Developer login on the ***[Red Hat login page](https://developers.redhat.com/login)***. 2. Once registered, you may complete the lab steps using ***[Red Hat's CodeReady Containers](https://cloud.redhat.com/openshift/install/crc/installer-provisioned)*** or the ***[Red Hat-provided OpenShift sandbox](https://developers.redhat.com/products/codeready-containers/overview)***. Solutions for using CodeReady Containers and the Red Hat OpenShift sandbox are available in this lab. *This lab is not approved or sponsored by Red Hat.*
