DevOps Workshop with OpenShift and OpenShift Ansible Broker

The DevOps Workshop provides full-stack and DevOps engineers an introduction to OpenShift, OpenShift Ansible Broker and containers and how OpenShift and Ansible can be used to build fully automated end-to-end deployment pipelines using advanced deployments techniques like rolling deploys and blue-green deployment.

The lab application used in this workshop is available at https://github.com/openshift-labs/devops-oab-labs
