What

We want to be able to pass the CLI version information to the backend server for CMF to perform compatibility checks. All the commands except web-ui-forward use a SDK which sets up the UserAgent header. We simply pass the value of the version to the same header. In case of web-ui-forward, since the origin of the calls will be from user's browser, we did not want to override the user agent header as it might be used by browsers for checks of their own, we have introduced a new header for just that API.

Validation

• I have verified that the version is being propagated into the request by using ldflags and validating that it has the same behaviour for the flink commands as the base version command

  
  > go run -ldflags "-X main.version=1.2.0" cmd/confluent/main.go  flink environment list --unsafe-trace
  2024/10/15 22:21:27
  GET /cmf/api/v1/environments?page=0&size=100 HTTP/1.1
  Host: localhost:8080
  User-Agent: Confluent-CLI/v1.2.0 (https://confluent.io; support@confluent.io)
  Accept: application/json
  Accept-Encoding: gzip

go run -ldflags "-X main.version=1.2.0" cmd/confluent/main.go --version confluent version v1.2.0
