Release Notes

kubernetes-sigs/external-dns (external-dns)

v1.21.1

Added
  • Add value .sourceNamespace to watch a namespace which is different from the one that external-dns is installed into when .namespaced is true. (#​6297) @​jplitza
  • Add option to enable Gateway API ListenerSet support. (#​6381) @​speer
  • Add support for bool in extraArgs. (#​6179) @​farodin91
  • Add value .namespaceOverride to render chart resources into a namespace different from the release namespace, for subchart installs that want their own namespace. (#​6389) @​alliasgher
Changed
Fixed
  • Avoid creating cluster-scoped RBAC for Gateway API sources when running namespaced with gatewayNamespace set. Namespace listing permissions are now only added when gatewayNamespace is unset. (#​5843) @​TobyTheHutt
  • Ensure container arguments are passed in as strings (#​6264) @​KhooHaoYit
  • Ensure container arguments are passed in as strings when extraArgs is a map (#​6284) @​vflaux
