Tips and Tricks
- Avoid split brain problem by setting minimum master nodes:
http://blog.trifork.com/2013/10/24/how-to-avoid-the-split-brain-problem-in-elasticsearch/
discovery.zen.minimum_master_nodes: set it to N/2 +1
discovery.zen.ping.timeout: change default if required to handle slow nodes
- Use boolean filters instead of and, or not, since they use bitsets
- Use filter over query for repeat searches, since filters are cached

Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

Prerequisites
