Kops toolbox instance selector

kops toolbox instance-selector

Generate instance-group specs by providing resource specs such as vcpus and memory.

Synopsis

Generate AWS EC2 instance groups by providing resource specs, such as vcpus and memory, rather than instance types.

  1. kops toolbox instance-selector INSTANCE_GROUP [flags]

Examples

  1.   ## Create a spot instance group using a MixInstancesPolicy and Capacity-Optimized spot allocation strategy.
  2.   ## --flexible defaults to a 1:2 vcpus to memory ratio and 4 vcpus.
  3.   kops toolbox instance-selector my-spot-mig --usage-class spot --flexible
  5.   ## Create an on-demand instance group with custom vcpu and memory range filters.
  6.   kops toolbox instance-selector ondemand-ig --vcpus-min=2 --vcpus-max=4 --memory-min 2gb --memory-max 4gb
