Getting the local docker-machine IP to add to no_proxy

.zshrc

# 
# This is the (brute force) way I'd thought to do it
eval "$(docker-machine env default)"

# get the IP address of our docker-machine,
# so we can add it to no_proxy below
DOCKER_IP=$(echo $DOCKER_HOST | sed 's#tcp://##' | sed 's#:.*##')
export no_proxy=lexmark.com,localhost,pvi.com,$DOCKER_IP

## this is the actual way to do it
eval "$(docker-machine env default --no-proxy)"

Bit of explanation for the above: We use an http proxy, so any time we want some traffic to a non-proxied program launched by the shell, need to add it to the no_proxy ENV var in my ZSH rc file.

You can use --no-proxy flag for docker-machine env:

$ docker-machine env --no-proxy default
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/Users/nathanleclaire/.docker/machine/machines/default"
export DOCKER_MACHINE_NAME="default"
export NO_PROXY="192.168.99.100"
# Run this command to configure your shell:
# eval $(docker-machine env --no-proxy)

Indeed!

eval "$(docker-machine env default --no-proxy)"

Works like a charm.
