--pid=pid

Sets the configuration for PID namespaces when handling RUN instructions. The configured value can be "" (the empty string) or "container" to indicate that a new PID namespace is created, or it can be "host" to indicate that the PID namespace in which podman itself is being run is reused, or it can be the path to a PID namespace which is already in use by another process.
