rpk -X

Use the -X flag to override any rpk-specific configuration option for a single command, without modifying your rpk profile. Each option follows the form key=value: for example, rpk -X tls.enabled=true enables TLS for the Kafka API.

Every -X option also has an environment-variable equivalent: prefix with RPK_ and replace periods (.) with underscores (_). For example, tls.enabled becomes RPK_TLS_ENABLED.

To list every available option, run:

rpk -X list

Run rpk -X help for inline descriptions, or see the full rpk -X reference in the Redpanda docs.

For persistent configuration across commands and sessions, prefer rpk profiles over environment variables or -X flags.
