As recommended in by CircleCI, explicitly specify the "latest" tag. This will be important when we will start versioning our images. Copied from CircleCI documentation [1]: "Make sure you tag the image you use in the FROM command in your Dockerfile, even if it is the default “latest” tag. Otherwise, Docker will pull down all tags for the image you specify. This will create significant performance problems because the save/load strategy described above only caches the image layers (and thus tags) that you specify in the docker save command, so other tags will be re-pulled on every build if a tag is not specified in the FROM command."

# Raspberry Pi is ARMv6+VFP2, Debian armhf is ARMv7+VFP3

# Since this Dockerfile is targeting linux-arm from Raspberry Pi onward,
|
|
# we're sticking with it's custom built cross-compiler with hardfp support.
|
|
# We could use Debian's armel, but we'd have softfp and loose a good deal
|

# of performance.

# See: https://wiki.debian.org/RaspberryPi

# Instead of cloning the whole repo (>1GB at the of writing this), we want to do a so-called "sparse checkout" with "shallow cloning":
