Error

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.

Examples:

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

After the quick-fix is applied:

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