Troubleshooting a Containerized Application
In this lab scenario, a containerized application is not working properly and needs to be fixed. Using the various logs available to us, we will find the issue, correct it, and start the application. *This lab is not approved or sponsored by Red Hat.* 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 one of the following methods: * Download ***[Red Hat's CodeReady Containers](https://cloud.redhat.com/openshift/install/crc/installer-provisioned)*** and install them locally on your own system. * Log in to your Red Hat Developer account and use a ***[Red Hat-provided OpenShift sandbox](https://developers.redhat.com/products/codeready-containers/overview)***. Solutions for CodeReady Containers and the Red Hat OpenShift sandbox are available in this lab.
