how to build docker

1. build

根据docker官方文档,一步步来即可。

1.清空容器、镜像等避免影响build过程

docker system prune -a
docker volume prune

2.下载代码

git clone https://github.com/moby/moby.git

3.进入docker提供的编译环境

cd moby
make BIND_DIR=. shell

等待约15分钟，会进入到一个容器

root@7fd23c4e7515:/go/src/github.com/docker/docker#

4.修改代码 修改cmd/dockerd/docker.go中的代码

sed -i "s@build %s@build %s, modified by st0n3@g" cmd/dockerd/docker.go

5.build

hack/make.sh binary install-binary

6.binary build好的二进制文件位于/go/src/github.com/docker/docker/bundles/binary-daemon

root@7fd23c4e7515:/go/src/github.com/docker/docker/bundles/binary-daemon# ./dockerd --version
Docker version dev, build d086c52c9a, modified by st0n3

2. troubleshooting

2.1 GFW

配置systemd代理

https://docs.docker.com/config/daemon/systemd/

也可以使用socks协议

[Service]
Environment="HTTP_PROXY=socks5://172.17.0.1:1082/"
Environment="HTTPS_PROXY=socks5://172.17.0.1:1082/"

使用以下命令获取环境或编译二进制

make DOCKER_BUILD_APT_MIRROR=ftp.cn.debian.org BIND_DIR=. shell

或

make DOCKER_CROSS=false build

遇到错误,就在对应的镜像下配置代理,例如

FROM base AS swagger
ENV http_proxy="socks5://172.17.0.1:1082"
ENV https_proxy="socks5://172.17.0.1:1082"

如果遇到go语言相关错误, 配置goproxy, 例如

FROM base AS golangci_lint
ENV GOPROXY=https://goproxy.cn,direct

socks协议可能对部分镜像无效, 则可以使用http代理, 例如

FROM dev-base AS tini
ENV http_proxy="http://172.17.0.1:8118"
ENV https_proxy="http://172.17.0.1:8118"

我改过的地方如下：

...
FROM base AS swagger
ENV http_proxy="socks5://172.17.0.1:1082"
ENV https_proxy="socks5://172.17.0.1:1082"
...
FROM base AS vndr
ENV http_proxy="socks5://172.17.0.1:1082"
ENV https_proxy="socks5://172.17.0.1:1082"
...
FROM dev-base AS proxy
ENV http_proxy="socks5://172.17.0.1:1082"
ENV https_proxy="socks5://172.17.0.1:1082"
...
FROM base AS golangci_lint
ENV GOPROXY=https://goproxy.cn,direct
...
FROM base AS gotestsum
ENV GOPROXY=https://goproxy.cn,direct
...
FROM base AS shfmt
ENV GOPROXY=https://goproxy.cn,direct
...
FROM dev-base AS dockercli
ENV http_proxy="socks5://172.17.0.1:1082"
ENV https_proxy="socks5://172.17.0.1:1082"
...
FROM dev-base AS rootlesskit
ENV http_proxy="socks5://172.17.0.1:1082"
ENV https_proxy="socks5://172.17.0.1:1082"
...
