Anybody using spot instances for worker nodes?

• aws-node-termination-handler

  93 1,566 8.0 Go

  Gracefully handle EC2 instance shutdown within Kubernetes

  

First, install the AWS Spot Termination Handler to ensure you gracefully handle terminations. Along with other standard things you should install like Cluster Autoscaler to handle failures/scale outs.

• eksctl

  59 4,781 9.5 Go

  The official CLI for Amazon EKS

  

Second, make sure you create a spot instance group that attempts to launch MULTIPLE different instance types. This way if one instance type gets flushed, your autoscaler will kick in and launch a different type. Without this, you WILL HAVE DOWNTIME if a sudden price hike and flush occurs. If you're using eksctl I have example configurations that use multi-instance types on Github here.

Avoid managed node groups for now if you like saving money with spot, but leave a thumbs up at https://github.com/aws/containers-roadmap/issues/1903

• amazon-ec2-instance-selector
