For AI agents: The documentation index is at https://docs.digitalocean.com/llms.txt. Markdown versions of pages use the same URL with index.html.md in place of the HTML page (for example, append index.html.md to the directory path instead of opening the HTML document).

When you upgrade an existing DigitalOcean Kubernetes (DOKS) cluster to version 1.37 or later, DOKS automatically enables the CoreDNS Cluster Proportional Autoscaler (CPA) plugin if CoreDNS is still running the default of two replicas. If you have manually changed the CoreDNS replica count, DOKS leaves it as is, and you can enable CPA yourself. CPA is already enabled by default on new clusters running Kubernetes 1.36 or later. For more information, see How to Configure CoreDNS Autoscaling.
