# This file describes the standard way to build Docker in a container on Windows
# Server 2016.
#
# Maintainer: @jhowardmsft
# -----------------------------------------------------------------------------------------


# Prerequisites:
# --------------
#
# 1. Windows Server 2016 with all Windows updates applied. Pre-release versions
#    of Windows are not supported (eg Windows Server 2016 TP5). The build number
#    must be at least 14393. This can be confirmed, for example, by running the
#    following from an elevated PowerShell prompt - this sample output is from a 
#    fully up to date machine as at late October 2016:
#
#    >> PS C:\> $(gin).WindowsBuildLabEx
#    >> 14393.321.amd64fre.rs1_release_inmarket.161004-2338
#
# 2. Git for Windows (or another git client) must be installed. https://git-scm.com/download/win.
#
# 3. The machine must be configured to run containers. For example, by following
#    the quick start guidance at https://msdn.microsoft.com/en-us/virtualization/windowscontainers/quick_start/quick_start or
#    https://github.com/docker/labs/blob/master/windows/windows-containers/Setup.md


# -----------------------------------------------------------------------------------------


# Usage:
# -----
#
#  The following steps should be run from an (elevated*) Windows PowerShell prompt. 
#
#  (*In a default installation of containers on Windows following the quick-start guidance at
#    https://msdn.microsoft.com/en-us/virtualization/windowscontainers/quick_start/quick_start,
#    the docker.exe client must run elevated to be able to connect to the daemon).
#
# 1. Clone the sources from github.com:
#
#    >>   git clone https://github.com/docker/docker.git C:\go\src\github.com\docker\docker
#    >>   Cloning into 'C:\go\src\github.com\docker\docker'...
#    >>   remote: Counting objects: 186216, done.
#    >>   remote: Compressing objects: 100% (21/21), done.
#    >>   remote: Total 186216 (delta 5), reused 0 (delta 0), pack-reused 186195
#    >>   Receiving objects: 100% (186216/186216), 104.32 MiB | 8.18 MiB/s, done.
#    >>   Resolving deltas: 100% (123139/123139), done.
#    >>   Checking connectivity... done.
#    >>   Checking out files: 100% (3912/3912), done.
#    >>   PS C:\>
#
#
# 2. Change directory to the cloned docker sources:
#
#    >>   cd C:\go\src\github.com\docker\docker 
#
#
# 3. Build a docker image with the components required to build the docker binaries from source:
#
#    >>   docker build -t nativebuildimage -f Dockerfile.windows .
#
#
# 4. Build the docker executable binaries in a container:
#
#    >>   docker run --name binaries nativebuildimage sh -c 'cd /c/go/src/github.com/docker/docker; hack/make.sh binary'
#
#
# 5. Copy the binaries out of the above container, replacing HostPath with an appropriate destination 
#    folder on the host system where you want the binaries to be located.
#
#    >>   $v=$(Get-Content ".\VERSION" -raw).ToString().Replace("`n","").Trim()
#    >>   docker cp binaries:C:\go\src\github.com\docker\docker\bundles\$v\binary-client\docker-$v.exe C:\HostPath\docker.exe
#    >>   docker cp binaries:C:\go\src\github.com\docker\docker\bundles\$v\binary-daemon\dockerd.exe C:\HostPath\dockerd.exe
#    >>   docker cp binaries:C:\go\src\github.com\docker\docker\bundles\$v\binary-daemon\docker-proxy-$v.exe C:\HostPath\docker-proxy.exe
#
#
# 6. (Optional) Remove the interim container holding the built executable binaries:
#
#    >>    docker rm binaries
#
#
# 7. (Optional) Remove the image used for the container in which the executable
#    binaries are build. Tip - it may be useful to keep this image around if you need to
#    build multiple times. Then you can take advantage of the builder cache to have an
#    image which has all the components required to build the binaries already installed.
#
#    >>    docker rmi nativebuildimage

# Important notes:
# ---------------
#
# The posix utilities from git aren't usable interactively as at October 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. It will not work.
#
# Don't attempt to use a volume for passing the source through to the container. The posix utilities will
# balk at reparse points. 
#
# The downloaded files are not cleared from the image. go.zip is used by the Windows
# CI servers to ensure the host and image are running consistent versions of go.
#
# The GIT installer isn't very good at unattended install. We use techniques described
# at the links below to force it to set the path and other options accordingly. 
# >> http://superuser.com/questions/944576/git-for-windows-silent-install-silent-arguments 
# and follow through to installer at

#
# As of October 2016, this does not work on Windows 10 client, just Windows Server 2016,
# and only with the default isolation mode (process). It does not work with isolation mode
# set to Hyper-V containers (hyperv).

#  - GO_VERSION must be consistent with 'Dockerfile' used by Linux.
