Replace Docker for Mac using the Docker CLI and Docker-Machine with Virtualbox

# intro
Hello
Recently the folks behind the Docker project, in a perfectly reasonable attempt at monetizing
announced that for companies of more than 250 employees or greater than 10M usd in annual revenue
will have to transition to a 7 USD per user per month model. At 250 employees with say half in engineering
that's 125 x 7 x 12 = 10.5k per year for Docker on the Desktop but more like 31.5k at 21 usd per month per employee for the enterprise features like SSO and such

# Caveats
The Docker for Desktop suite does have some value add that if you use you should ask your employer
to pay for but for me and my use-case I just need to be able to run some cointainers maybe even some
docker-compose files to spin up some interconnected sets of containers and if that's your usecase as
well then follow along.
# solution
There is a workaround that I will explain in this video that is pretty simple to do
# pre-reqs
First you'll need homebrew -- we like homebrew on this channel
An Internet connection
A modern-ish Intel mac -- I've not tested this on Apple Silicon -- so all you lucky folks with an M1 your mileage may vary
Paitence to run some terminal commands
# commands
# brew update && brew upgrade && brew install virtualbox && brew uninstall --cask docker && brew install docker && brew install docker-machine
# docker-machine create --driver=virtualbox --virtualbox-disk-size=100000 --virtualbox-memory=8192 --virtualbox-cpu-count=4 foo
Add eval $(docker-machine env foo) to your bashrc or zshrc
# test
# docker run -d -p 8080:80 nginx
# curl docker-host-ip:8080
# end
Thanks for watching
