ORIGINAL TALK TITLE
Lowering the Barriers to Entry for Kubernetes
ABSTRACT
The Kubernetes eco-system is quickly becoming the de facto way to run applications. The toolbox is chock-full of tools that can be hard to let go off once you’ve tried them.
Large-scale Kubernetes deployments in the cloud or on-premises can be a daunting task to set up. Sometimes you can’t justify the cost of a managed Kubernetes cluster because the project is still in its infancy? What if you don’t need a highly-available multi-node cluster? Should you go back to running Docker containers on a simple VM?
In this talk we will look at how single-node Kubernetes clusters using K3s can be a way to lower the barrier of entry for Kubernetes, while still getting the benefits of GitOps, rolling deployments, and mature monitoring solutions. We’ll also discuss next steps if you outgrow your single-node cluster [...]
