False warning about lack of `yum clean all`

[dharmit]

For this Dockerfile, one of the warning messages we get from linter is about lack of yum clean all. You can find complete logs here.

But there's already a yum clean all statement in the Dockerfile.

We use this branch of the linter to lint Dockerfiles.

We're also experiencing this issue, the regex should match yum clean all anywhere in the line. I get this as output :

# Analyzing Dockerfile


-------WARNINGS--------

Line 32: -> RUN yum remove -y       wget &&     yum clean all &&     rpm -e --nodeps yum &&     rm -f /usr/bin/rpm
WARNING: yum clean all is not used. the yum cache will remain in this layer making the layer unnecessarily large.

Is there a way of fixing this or excluding this rule?
