A container can be deleted, which will cause any connected user to be disconnected immediately. The following command deletes a single container:
amc delete bcqbicqhmss0448iie2g
The ID given is the one of the container you want to delete.
In some cases, it is helpful to delete all containers currently available.
The amc command provides a --all flag for this, but be careful with this!
amc delete --all
