Configuring Multiple Schema Registries
Kpow supports multiple Schema Registries associated to a single Kafka cluster.
To configure multiple Schema Registries, use the environment variable SCHEMA_REGISTRY_RESOURCE_IDS to define a comma separated list of Schema Registries. Kpow uses the resource ID as a prefix in the environment variable.
Example configuration when configuring two Schema Registries:
SCHEMA_REGISTRY_RESOURCE_IDS=US1,EU2
US1_SCHEMA_REGISTRY_URL="https://us1.schema-registry.mycorp.org"
US1_SCHEMA_REGISTRY_AUTH="USER_INFO"
US1_SCHEMA_REGISTRY_USER=""
US1_SCHEMA_REGISTRY_PASSWORD=""
EU2_SCHEMA_REGISTRY_URL="https://eu2.schema-registry.mycorp.org"
EU2_SCHEMA_REGISTRY_AUTH="USER_INFO"
EU2_SCHEMA_REGISTRY_USER=""
EU2_SCHEMA_REGISTRY_PASSWORD=""
Multiple Schema Registries are navigable via the left hand or context menus.
