 - You must have either a `datasource` capture group or a `datasourceTemplate` config field
 - You can optionally have a `versioning` capture group or a `versioningTemplate` config field. If neither are present, `semver` will be used as the default
 - You can optionally have a `currentDigest` capture group.
+- You can optionally have a `registryUrl` capture group. If it's a valid URL, it will be converted to the `registryUrls` field as a single-length array.
