dapr - v1.9.1


Dapr 1.9.1

Fixes mDNS name resolver component not working on systems with IPv6 disabled

Problem

Users running Dapr in self-hosted mode and relying on the mDNS name resolver (the default when not running in Kubernetes) would encounter errors trying to perform service invocation if the system had IPv6 disabled.

Impact

This issue impacts users who are:

  • running Dapr in self-hosted mode, and
  • using the default mDNS name resolver, and
  • have disabled IPv6 on the operating system

Root cause

When initializing a zeroconf (mDNS) client, Dapr required using both IPv4 and IPv6, and failed if either one of the two protocols was disabled on the host system.

Solution

We have improved error handling so Dapr gracefully falls back to using IPv4 if binding to IPv6 fails.
