Hi,
I have two questions related to Docker container communication and security.
I have seen that container-to-container communication can be secured via encryption by enabling a secure flag.
Is this feature available for any stand-alone containers spawned via docker run on the default (or custom made) bridge interface?
Or is it only available in the swarm-mode amongst containers that are in the same overlay network?
And then, is there a similar feature to that of SSL mutual authentication amongst containers? As in to say, only containers with a certificate signed by a specific CA can talk to each other?
Or any other mechanism to restrict what containers can talk to which containers even when they are part of the same overlay network?
Thanks
Shabir
