Second this bug / feature request as URGENT, especially since one cannot tell Hadolint to “ignore” it as it’s not reported as rule violation https://github.com/docker/cli/issues/4486

Guys, according to my tests, this flag does not do anything (it does not work). Is it working for any of you?

It is a valid option and hadolint should die over it.

[felipecrs]

Surely.

This is indeed pretty irritating. So far no way to suppress this I guess. Anybody looking at this currently? Now this option (i.e. "--start-interval=5s") can not be used in Dockerfile if hadolint is used.

How can I ignore the rule that produces this error?

I guess what @kx1t means is that this error emerges from the parser itself (--start-interval is not listed as a known flag). So, it is not implemented as a rule and cannot be disabled.

Should we create an feature request for this directly at https://github.com/hadolint/language-docker?
