      # Quoting variables like $FOO, ${FOO} or ${{FOO}} is required, since some tools, like k3d, preprocess the YAML files
      # and replace the variables with their values. If the value is not quoted, it sometimes leads to schema validation errors.
      # For example, if the configuration is like `port: ${REGISTRY_PORT}`, it will be replaced with `5000`, and the resulting
      # configuration will be `port: 5000` which type is number, but the schema expects a string like `port: "5000". To prevent
      # this, we should quote every variable for safety. About this regex, see https://regex101.com/r/IblYeC/1
