For those of you who have been following the rise of the Operators across the Kubernetes eco-system and were wondering what all the excitement was about, here’s your chance to get up to speed quickly and get some hands-on experience building them.
This is day-long hands-on workshop is co-located with Red Hat Summit in Boston, workshop attendees must also be registered for Red Hat Summit. If you’d like to come, please request an invitation today and we’ll send you further details.
This is an entry-level workshop 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
