Kubernetes 编译

kubernetes 编译

1. 默认mac 编译会报错

/usr/local/go/pkg/tool/linux_amd64/link: signal: killed 通过查看原因，发现是docker 默认在mac 版本上的资源限制问题，解决问题如下

选择docker 的首选项-设置

修改完毕，点击应用即可

2.设置docker代理

根据代理软件设置所对应的代理

3. 编译

git clone https://github.com/kubernetes/kubernetes
cd  kubernetes 
git checkout  v1.19.4
./build/run.sh make   开始执行编译(是在容器中编译)

4. 关于证书期限

**** 修改cert.go 文件

vim   staging/src/k8s.io/client-go/util/cert/cert.go 
.................
# 默认已经是10年，可以不修改，最高99年，不超过100
NotAfter:              now.Add(duration365d * 10).UTC(),
..........

**** 修改constants.go 文件

vim cmd/kubeadm/app/constants/constants.go
.............
#默认是一年，修改为10年
CertificateValidity = time.Hour * 24 * 365
.............

#修改
CertificateValidity = time.Hour * 24 * 365 * 10 
重新编译kubeadm 
make all WHAT=cmd/kubeadm GOFLAGS=-v

5. 制作pause 镜像

cd build/pause 
make container 
staging-k8s.gcr.io/pause-amd64:3.2  #生成镜像

6. 编译完成

1. 生成镜像
staging-k8s.gcr.io/hyperkube-amd64:v1.18.9   # 包含kube-apiserver 等组件信息的镜像
staging-k8s.gcr.io/pause-amd64:3.1           # pause 镜像
