October 2025 Monthly Summary: Across rancher/turtles, rancher/rancher, and rancher/turtles-docs, delivered substantial business value by hardening air-gapped installation flows, enhancing configurability, and improving provisioning reliability. Key changes include refactoring the Rancher Turtles chart to support air-gapped CAPI installations by removing embedded CAPI and embedding core CAPI components, with default installation now sourced from a local ConfigMap. Added clusterctl-level flexibility to override CAPI image registries for private or custom registries. Reduced maintenance complexity by cleaning up deprecated CAPI/RKE2 configurations and removing post-delete steps. Strengthened fleet provisioning robustness by improving error handling and ensuring required namespaces are created with proper labeling. Clarified and expanded air-gapped installation guidance in docs to help operators understand how the core CAPI provider/CRDs are delivered in offline environments and how to customize fetch configurations. In addition, a GitHub Actions workflow token variable was fixed to correct the environment variable name, improving CI reliability and build stability.
