Tonight's mission - get an application from the day job up and running on one of my Macs at home...
So, Docker is designed to run on top of a Linux kernel - which Mac OS X obviously doesn't offer.
A quick Google leads to:
which directs me to Boot2Docker :
Open the downloaded package and double click to install the VM image
Binaries are now on the path and ready to run from a command line terminal:
> boot2docker init
> boot2docker start
Then the top secret bit for pulling down the Dockerised application...
Tweak the configuration properties to use the newly created Docker host instead of the hand-coded Linux environment's Docker configuration (host IP address).
Run the application's tests.
Let out a satisfied "Aaah" or "Mmm" (optional).
This all took about 20 minutes, but most of the time was spent waiting on downloads.
