This workshop is intended to give you a hands on introduction to using OpenShift from the perspective of a Developer.
Containers are a standardized way to package apps with all of their dependencies to simplify deployment and speed delivery. Unlike virtual machines, containers do not bundle to the operating system. Only the application code, run time, libraries, and settings are packaged inside of containers. Thus, containers are more lightweight, portable, and efficient as compared to virtual machines.
For developers looking to kickstart their projets, OpenShift enables efficient application development through streamlined workflows and validated integrations.
You can run this Lab on any OpenShift cluster, either Managed and Self-Managed, just git it a try!
