Boot2Docker with Cisco AnyConnect

Boot2Docker is an OS X app used to create a virtual environment for docker.  Docker only runs on Linux, so Boot2Docker installs a VM on your mac (using virtual box) and a client that runs locally to communicate with the VM. I downloaded this and followed instructions.  You basically just install it with a few clicks.  Once […]
