SharedCollisionDomains

Kathará allows deploying network scenarios sharing collision domains with the user on the same host, either local or remote (see the Remote Docker Connection guide).

To enable shared collision domains, open the Kathará settings:

kathara settings

This will open the setting menu:

If different users (on the same host or connected to the same docker daemon) enable the shared collision domain option, they can connect their devices with the devices deployed by other users.
