Summary
Introducing the concept of dynamicMetadata.
There are situations in which you want to pass additional information specific for the instance of the Dataplane. This information is sent from Kuma DP to Kuma CP in bootstrap request. Then it is attached to bootstrap configuration and sent via XDS. XDS generators can then use this information.
We use this flow for example to retrieve information about admin port or dataplane token.
This PR lets you add additional dynamicMetadata in
RootContextof Kuma DP which can be then used in XDS generators.Documentation
