# CONFIGURE script for setting up docker under UNIT school infrastructure

# To INSTALL docker follow instructions below:
# $> curl -fsSL https://rawgit.com/kube/42homebrew/master/install.sh | zsh
# Then relaunch terminal... and fire next command:
# $> brew install docker docker-machine docker-compose

# Alternate way to install docker-compose:
# $> sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# Becouse in UNIT we have only 5Gb of personal user storage it seems expedient
# to link ~/.docker file to some big tmp storage either ~/goinfre or /tmp
