Can I find Dockerfile format structure (keywords, examples, etc) in a standalone RHEL OS installation? So that during a certification test I could lookup the format if I forget something. I know many OS commands have stuff like "man 5 command" to get their config file structure details, but I cannot seem to find anything like that for a Dockerfile or Containerfile
This is valid for any type of file you might need, so take your peek
# yum provides "**/Dockerfile"
# yum install buildah-tests (for example)

Thanks @Fran_Garcia !!! That is exactly the kind of info I needed. Never really thought to globally search the repositories for example files. That'll help a lot in case I forget a keyword or syntax in a closed-off cert test lab environment
AFAIK RHEL8 man pages provide no example and no explanation of the syntax of Dockerfile, just like RHEL8 gcc package provides no tutorial on the C programming language.
But you can find a few examples of Dockerfiles and recommended practices in the "Building, running, and managing containers" guide from RHEL8 at
