Brian and Tyler talk about updates to Kubernetes v1.12
 
Show Notes:

Topic 1 - Kubelet TLS Bootstrap moves to GA - simplify how nodes are securely added/removed into a cluster. As an add-on,  server certificate rotation functionality moves into beta, and this will be tied in with Cluster Operators and Application Operators.

Topic 2 - Azure Virtual Machine Scale Sets (VMSS) and Cluster-Autoscaler is Now Stable

Topic 3 - On the network security front, two NetworkPolicy components graduate to GA: egress and ipBlock.

Topic 4 - Multi-Tenancy: In this release comes the ability to support priority on the various resource quotas via the new ResourceQuotaScopeSelector feature. This enhances the existing priority and preemption feature that was delivered in Kubernetes 1.11.

Topic 5 - CSI now supports the notion of topology awareness and this functionality moves to beta in Kubernetes 1.12. What this means is that stateful workloads can now have a conceptual understanding of where storage resources live, whether it be a rack, datacenter, availability zone, or region.

Topic 6 - Kubectl Plugins: With kubectl plugins, developers can engineer extensions to kubectl, which accommodate their administration scenarios, while not being baked into the core kubectl codebase. This is going to allow teams to develop and deliver kubectl functionality faster and in a more consistent manner. (example: OpenShift “oc commands”) Topic 7 - Let’s discuss the upgrading process of Kubernetes (again).
