编译调试docker

参考:

---

• Work with a development container
• github.com/docker/cli

示例:

1、编译 dockerd

$ git clone https://github.com/moby/moby.git
$ cd moby && make BIND_DIR=. shell
root@697ab9a6fb54:/go/src/github.com/docker/docker# hack/make.sh binary install-binary run

$ docker exec -it 697ab9a6fb54 bash
root@697ab9a6fb54:/go/src/github.com/docker/docker# ls bundles/17.06.0-dev/binary-daemon/
docker-containerd      docker-containerd-ctr.sha256  docker-containerd-shim.sha256  docker-init     docker-proxy     docker-runc         dockerd              dockerd-17.06.0-dev.sha256
docker-containerd-ctr      docker-containerd-shim    docker-containerd.md5      docker-init.md5     docker-proxy.md5     docker-runc.md5     dockerd-17.06.0-dev
docker-containerd-ctr.md5  docker-containerd-shim.md5    docker-containerd.sha256   docker-init.sha256  docker-proxy.sha256  docker-runc.sha256  dockerd-17.06.0-dev.md5

2、编译 docker

root@697ab9a6fb54:/go/src/github.com/docker/docker# cd .. && git clone https://github.com/docker/cli.git
root@697ab9a6fb54:/go/src/github.com/docker/cli# make binary
root@697ab9a6fb54:/go/src/github.com/docker/cli# ls build/
docker  docker-linux-amd64

3、调试

root@697ab9a6fb54:/go/src/github.com/docker/cli# git diff
diff --git a/cli/command/container/attach.go b/cli/command/container/attach.go
index dce6432..9384b0d 100644

Usage:  docker attach [OPTIONS] CONTAINER

Attach local standard input, output, and error streams to a running container

Options:
      --detach-keys string   Override the key sequence for detaching a container
      --help                 Print usage
      --no-stdin             Do not attach STDIN (standard in)
      --sig-proxy            Proxy all received signals to the process (default true)

4、测试: dockerd默认访问私有仓库
