2. 编译k8s仓库

参考：

2.1. 编译二进制

2.1.1. 基于docker构建容器编译。

该方式为官方镜像及二进制文件的构建方式。

构建镜像(大小：5.97GB)为： kube-build:build-8faa8d3cb7-5-v1.27.0-go1.20.6-bullseye.0

git clone https://github.com/kubernetes/kubernetes.git
cd kubernetes
build/run.sh make # 构建全部

#指定模块构建
build/run.sh make kubeadm

输出如下：

# build/run.sh make

2.1.2. 基于构建机环境编译

git clone https://github.com/kubernetes/kubernetes.git
cd kubernetes
# 构建全部二进制
make

# 构建指定二进制
make WHAT=cmd/kubeadm

输出如下：

# make WHAT=cmd/kubeadm

2.2. 编译镜像

git clone https://github.com/kubernetes/kubernetes
cd kubernetes
make quick-release
