Disable Inter-Container Communication (--icc=false)

By default, inter-container communication (icc) is enabled, so all containers can communicate with each other (using docker0 bridged network). This can be disabled by running docker daemon with --icc=false flag. If icc is disabled (icc=false), it is required to inform which containers can communicate using --link=CONTAINER_NAME_or_ID:ALIAS option. See more in Docker documentation - container communication.

In Kubernetes Network Policies can be used for it.
