Source: YouTube · Kubernetes · published Sep 25, 2025 · 27:09
The working group discussed the release of Carpenter 1.7 with node overlay support in alpha stage 0:13, which allows pricing updates and custom resource configurations to make Carpenter aware of resources it can't discover 1:13.
Key Takeaways:
• Carpenter 1.7 alpha release introduces node overlay support with custom resource configurations for AWS providers 0:13-0:39
• RFC proposes node limits per node pool with options for hard limits (absolute caps) and soft limits (allowing temporary excess during disruption) 5:16-6:03
• Configurable TTL RFC aims to implement max node provision time similar to cluster autoscaler 14:24-14:56
• Discussion about custom AMI support and label/taint reconciliation revealed these are handled through node claim lifecycle registration 18:03-21:03
• Nitro Enclaves support may require node overlay functionality to handle resource allocation properly 23:24-26:11
The team will continue developing these features with community feedback and further discussions scheduled in two weeks 26:57.
