Description

This is an entry-level workshop will be co-located with the OpenShift Commons Gathering in London on January 30th. Attendees must also be registered for the Gathering and are invited to stay on for the afternoon talks and evening reception with the OpenShift Community.

The workshop is for both application developers and system administrators interested in building and managing Operators for Kubernetes environments. It is designed for those who have a basic knowledge of Kubernetes and want to learn how to apply domain or application-specific knowledge to automate common operational tasks. Attendees will understand the past difficulties with building Operators with existing client-libraries and discover how the Operator Framework can ease development workflow. Attendees will also receive step-by-step guidance on the process of creating real-world Operators with Go, Ansible, and Helm charts while mastering methodologies, design patterns, and strategies that can assist in avoiding common pitfalls. After your Operator has been created, learn how to utilize the Operator Lifecycle Manager (OLM) to define, install, and upgrade your Operator and record cluster usage with the Operator Metering project.

All Operator Framework components are part of GitHub organization called “Operator Framework” located here: https://github.com/operator-framework under Apache License 2.0
