Build the newest Docker environment

This tutorial explains how to build the newest Docker environment. My host is Ubuntu 16.04.1, and it is already shipped withDocker 1.12.0:

# systemctl status docker
● docker.service - Docker Application Container Engine
   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
  Drop-In: /etc/systemd/system/docker.service.d
   └─http-proxy.conf
   Active: active (running) since Tue 2016-08-09 03:49:08 EDT; 3min 24s ago

 Version:  1.12.0

 Go version:   go1.6.3
 Git commit:   8eab29e

Server:
 Version:  1.12.0
 API version:  1.24

 OS/Arch:  linux/amd64

(1) The prerequisite is the Go environment is ready on your host, and GOPATH environment variable is also set. If not, please follow thisdocument to setup.

(2) Download the newest Docker code:

# go get -d -u github.com/docker/docker
package github.com/docker/docker: no buildable Go source files in /go/src/github.com/docker/docker

Build the Docker:

# cd $GOPATH/src/github.com/docker/docker/
# make DOCKER_BUILD_ARGS="--build-arg http_proxy=http://web-proxy.corp.xxxxxx.com:8080/ --build-arg https_proxy=https://web-proxy.corp.xxxxxx.com:8080/" DOCKER_DEBUG=1

Because my host works behind proxy, I need to specify proxy address in command line. Whether adding DOCKER_DEBUG or not depends on your personal flavor.

(3) After above building process succeeds, backup old Docker files:

# systemctl stop docker
# cd /usr/bin
# mkdir backup_docker
# mv docker* backup_docker

(4) Change back to $GOPATH/src/github.com/docker/docker/, and copy new Docker binaries:

# cd $GOPATH/src/github.com/docker/docker/
# cd bundles/latest/
# ls
binary-client  binary-daemon

binary-client contains Docker executable file:

# cd binary-client/
# ls
docker  docker-1.13.0-dev  docker-1.13.0-dev.md5  docker-1.13.0-dev.sha256
# cp docker /usr/bin/

Then copy Docker daemon related files:

# cd ../binary-daemon/
# ls
docker-containerd             docker-containerd.sha256       dockerd-1.13.0-dev         docker-proxy-1.13.0-dev.md5
docker-containerd-ctr         docker-containerd-shim         dockerd-1.13.0-dev.md5     docker-proxy-1.13.0-dev.sha256
docker-containerd-ctr.md5     docker-containerd-shim.md5     dockerd-1.13.0-dev.sha256  docker-runc
docker-containerd-ctr.sha256  docker-containerd-shim.sha256  docker-proxy               docker-runc.md5
docker-containerd.md5         dockerd                        docker-proxy-1.13.0-dev    docker-runc.sha256
# cp docker-containerd docker-containerd-ctr docker-containerd-shim docker-runc dockerd docker-proxy /usr/bin/

(5) Restart Docker and check it:

# systemctl start docker
# systemctl status docker
