I see DOCKER_HOST as an environment variable comes across in several discussions. I’m using CentOS Linux release 7.2.1511 (Core) to run my containers version 1.10.3. I am not able to find any documentation on DOCKER_HOST variables where it is to be used and why it is used . I’m able to use my containers without setting it but I’m pretty sure that I might have to use it sometime. I understand that it is currently mandatory for Mac OS.
Could someone please provide some information or point me to some information on it,
