Operating kube-apiserver Without Hiccups – Stefan Schimanski & David Eads, Red Hat
Kube-apiserver is the central component of every Kubernetes cluster. Keeping it available at all times is crucial for reliable operation. At the same time we want to restart kube-apiserver, for version upgrades, key rotation or just configuration changes. How can this be done without dropping a single request on the floor? Outline: – overview and problem statement – graceful termination – health and readiness checks – rolling upgrades – reliable use of informers in client apps – self-hosting done right, without self-references. David and Stefan are both the builders and the consumers of core apiserver infrastructure used in kube-apiserver, maintaining most of the code behind those features.
