2.http://searchsdn.techtarget.com/feature/Docker-networking-How-Linux-containers-will-change-your-network

Solution

Periodically check your container inventory per host and clean up the containers that are not needed using the below command-
docker rm $INSTANCE_ID

For example,
docker rm e3a7a1a97c58
Impact-
If you keep way too few number of containers per host, then perhaps you are not utilizing your host resources very adequately.
Default Value-
By default, Docker does not restrict the number of containers you may have on a host.
