karpenter_instance_families

Description

The karpenter_instance_families parameter specifies which EC2 instance families Karpenter can use when provisioning workload nodes. Karpenter selects the optimal instance type from the allowed families based on pending pod requirements.

Default Value

The default value is empty (all general-purpose instance families are allowed).

Setting the Parameter

$ convox rack params set karpenter_instance_families=c5,m6i,r5 -r rackName
Setting parameters... OK

Additional Information

• Validation: Comma-separated lowercase alphanumeric values (e.g., c5,m6i,r5).
• Combine with karpenter_instance_sizes to further constrain instance selection.
• Build nodes use karpenter_build_instance_families, which falls back to this value if unset.
