KubeCon + CloudNativeCon 2019: Fixing Kubernetes Clusters at Scale
Securely operate and upgrade your clusters at scale
As a hosting provider, SysEleven has the challenge to run and manage multiple Kubernetes clusters for various customers on their infrastructure in a secure way. The majority of these clusters are fully managed by them. Customers want to build and run containers, not maintain and upgrade them.
In this talk, Simon Pearce from SysEleven and Sebastian Scheele from Kubermatic will give you a breakdown of how customers can secure their clusters and how to force Kubernetes upgrades to all of them in a scalable way. As an example the Kubernetes API bug occurred in December 2018 is used to show how to fix all clusters in a very short time frame.
