Code Inspection: Unquoted port mappings

Reports unquoted port mappings in Docker Compose files.

According to the Compose file specification, mapping ports in the HOST:CONTAINER format may lead to erroneous results when using a container port lower than 60, because YAML parses numbers in the format xx:yy as a base-60 value. For this reason, we recommend always explicitly specifying the port mappings as strings.


ports: - 3000 - 3000-3005 - 22:22 - 8080:8080

After the quick-fix is applied:

ports: - "3000" - "3000-3005" - "22:22" - "8080:8080"

Suppress an inspection in the editor
