rpk registry schema create

Create a schema for the given subject.

This uploads a schema to the registry, creating the schema if it does not exist. The schema type is detected by the filename extension: ".avro" or ".avsc" for Avro, ".json" for JSON, and ".proto" for Protobuf. You can manually specify the type with the --type flag.

You may pass the references using the --reference flag, which accepts either a comma separated list of <name>:<subject>:<version> or a path to a file. The file must contain lines of name, subject, and version separated by a tab or space, or the equivalent in json / yaml format.

In import mode, you can specify a schema ID and version using the --id and --schema-version flags to assign specific values when creating the schema.

Usage

rpk registry schema create SUBJECT --schema {filename} [flags]
