**No NoSonar Support:**

Trailing comments are not permitted in Dockerfiles. For this reason, our Dockerfile parser does not support NOSONAR comments to suppress issues. Issues and hotspots must be reviewed in the UI.

**Missing Uniform Filename Convention:**

Dockerfiles can have all kinds of names and do not need a file extension. For this reason, it is difficult for the scanner and the analyzer to recognize all Dockerfiles. By default, all files named Dockerfile, Dockerfile.\*, or \*.dockerfile are considered Dockerfiles. If other conventions apply, these can be specified via the scanner property sonar.lang.patterns.docker.
