mDNS name resolution provider spec
Multicast DNS (mDNS) is configured automatically in self-hosted mode by Dapr. There is no configuration needed to use mDNS as your name resolution provider.
The component resolves target apps by using the host system’s mDNS service. You can learn more about mDNS here.
In some cloud provider virtual networks, such as Microsoft Azure, mDNS is not available. Use an alternate provider such as HashiCorp Consul instead.
On some enterprise-managed systems, mDNS may be disabled on macOS if a network filter/proxy is configured. Check with your IT department if mDNS is disabled and you are unable to use service invocation locally.
Not applicable, as mDNS is configured by Dapr when running in self-hosted mode.
