Introduction The File Integrity Operator is used to watch for changed files on any node within an OpenShift cluster. Once deployed and configured, it will watch a set of pre-configured locations and report if any files are modified in any way that were not approved. This operator works in sync with MachineConfig so if you update a file through MachineConfig, once the files are updated, the File Integrity Operator will update its database of signatures to ensure that the approved changes do not trigger an alert.
