Operating system-level virtualization discovery
Discovery can collect image and container information from Operating system-level virtualization (OS-level virtualization) engines.
Discovery can determine container status and size and identify images and their tags provided by operating-system-level virtualization.
Note: Currently, the ServiceNow® platform supports the discovery of Docker virtualization containers only.
Table schema
| Table | Description |
|---|---|
| cmdb_ci_oslv_engine | Base table for all OSLV engines. |
| cmdb_ci_oslv_image | Base table for globally unique OSLV images. |
| cmdb_ci_oslv_local_image | Base table for local instances of OSLV images. |
| cmdb_ci_oslv_image_tag | Base table for tags on OSLV images. |
| cmdb_ci_oslv_container | Base table to store containers found on the host. |

- Docker virtualization
Discovery uses the Docker Pattern to collect data about specific objects in a Docker engine, running on a Linux host.
