ONBUILD, FROM or MAINTAINER triggered from within ONBUILD instruction.

Problematic code:

ONBUILD ONBUILD /bin/true
ONBUILD FROM debian
ONBUILD MAINTAINER Ron Weasley

Correct code:

None.

Rationale:

These three cases are errors in Dockerfiles. See: https://docs.docker.com/engine/reference/builder/#onbuild
