How long does a node launched by EKS Auto Mode live?

Question

Accepted Answer

At most 21 days, after which it is replaced automatically — Auto Mode nodes have a maximum lifetime of 21 days, which you can shorten, and are then replaced with fresh instances. That pairs with immutable AMIs, SELinux enforcement and read-only root file systems: nothing is patched in place, and regular cycling is the security posture rather than a side effect. Replacement does not wait for workloads to drain away on their own, and it is not tied to cluster version upgrades.

Answer

Until its workloads drain, since Auto Mode replaces nodes only on demand

Answer

Until the next Kubernetes version upgrade of the cluster it belongs to

Answer

As long as its instance is healthy, with patches applied to it in place
