This is a Dockerfile sanity and semantics checker. It provides hints based on best practices.
Currently output is json to be displayed by web front-end.
The rules used to validate the Dockerfile are defined by a yaml file. To customize the ruleset copy the dockerfile_rules.yaml, edit the file and pass the --rules
argument to specify the custom dockerfile ruleset.
Running
./check_dockerfile.py <path/to/Dockerfile> [--rules <path/to/custom/rules.yaml>]
TODO
-
DONE: check is a ssh rpm gets installed => no good

-
check if a user is created within the Dockerfile
-
DONE: check if ports got EXPOSEd
