universe.resource.v1

Note

This API is available for Tenants only

Proto file, generated GO client and test tool for the API can be found in universe-api repo

This API is served by universe-infra-resource-manager

The intent of this API is to provide a way to create Kubernetes resource in the infrastructure cluster from the Tenant cluster.

universe-k8s-tenant-resource-plugin relies on this API for resource creation.

check Manual GRPC API usage doc before start

Here some examples using ‘grpcurl’ tool to access the API:

Note

Replace $API_GW_ADDRESS with address of iCP API GW in your environment

Replace $TENANT_ID with existing tenant id

Create and Update requests contain binary fields. grpcurl utility requires binary fields to be encoded to base64 encoded before they can be used as request parameters.
