+The base layer OS package manager invocation and resolution of installed packages by [docker_inspector_name] is restricted to Ubuntu, CentOS, and Alpine base OS layer images. If the image meets other requirements and regardless of the base layer OS, [docker_inspector_name] will run a signature scan/analysis on the tarball of the image and produce matches if any. For example, if the base layer OS is CentOS, [docker_inspector_name] will start CentOS image inspector container service, mount the image onto this container and run "rpm qa" to get a list of installed packages if available.

+Should unresolvable errors occur during attempts to scan Docker images we recommend switching to analysis via [Container Scan](../../runningdetect/containerscanning.md) of Docker images.
