Abstract: A computer-implemented method of determining installation compatibility includes identifying one or more entities of an uninstalled operator. The identified one or more entities of the uninstalled operator are parsed and information is extracted from the one or more entities. An existing operator installed on a target container cluster is parsed and information extracted from the entities of the existing operator. The extracted information from the uninstalled operator is compared with the extracted information from the existing operator. A disruption risk to operation of the target container cluster is ranked based on the comparing of the extracted information of the uninstalled operator with the extracted information of the existing operation.
