# This file describes the standard way to build Docker, using a docker container on Windows 
# Server 2016
#
# Usage:
#
# # Assemble the full dev environment. This is slow the first time. Run this from
# # a directory containing the sources you are validating. For example from 
# # c:\go\src\github.com\docker\docker
#
# docker build -t docker -f Dockerfile.windows .
#
#
# # Build docker in a container. Run the following from a Windows cmd command prommpt,
# # replacing c:\built with the directory you want the binaries to be placed on the
# # host system.
#
# docker run --rm -v "c:\built:c:\target" docker sh -c 'cd /c/go/src/github.com/docker/docker; hack/make.sh binary; ec=$?; if [ $ec -eq 0 ]; then robocopy /c/go/src/github.com/docker/docker/bundles/$(cat VERSION)/binary /c/target/binary; fi; exit $ec'
#
# Important notes:
# ---------------
#
# 'Start-Sleep' is a deliberate workaround for a current problem on containers in Windows 
# Server 2016. It ensures that the network is up and available for when the command is
# network related. This bug is being tracked internally at Microsoft and exists in TP4.
# Generally sleep 1 or 2 is probably enough, but making it 5 to make the build file
# as bullet proof as possible. This isn't a big deal as this only runs the first time.
#
# The cygwin posix utilities from GIT aren't usable interactively as at January 2016. This
# is because they require a console window which isn't present in a container in Windows.
# See the example at the top of this file. Do NOT use -it in that docker run!!! 
#
# Don't try to use a volume for passing the source through. The cygwin posix utilities will
# balk at reparse points. Again, see the example at the top of this file on how use a volume
# to get the built binary out of the container.
#
# The steps are minimised dramatically to improve performance (TP4 is slow on commit)

#  - GOLANG_VERSION must consistent with 'Dockerfile' used by Linux'.
#  - FROM_DOCKERFILE is used for detection of building within a container.
