docker源码目前分为两部分 cli 和 moby

Starting with the Docker 20.10 release, packages for the Docker Engine and Docker CLI are built directly from their respective source repositories instead of from this repository.

docker-ce：https://github.com/docker/docker-ce

cli：https://github.com/docker/cli

moby: https://github.com/moby/moby

首先在 GOPATH / src 下创建 github.com/docker 目录，然后 git clone cli moby 到这个目录，修改 moby 名称为 docker

mkdir -p $GOPATH/src/github.com/docker
cd $GOPATH/src/github.com/docker
git clone https://github.com/docker/cli
git clone https://github.com/moby/moby
mv moby docker
