执行命令:在kubernetes顶层目录执行
build/run.sh make,发生错误:Step 1/16 : FROM us.gcr.io/k8s-artifacts-prod/build-image/kube-cross:v1.14.6-1 Get https://us.gcr.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers) -
安装本地docker registry(这里需要本地的registry,只需要本地docker有这个镜像就可以了)
- Deploy a registry server
- 先在香港节点的服务器上拉下镜像: us.gcr.io/k8s-artifacts-prod/build-image/kube-cross:v1.14.6-1, 然后
docker save -o kube-cross.tar us.gcr.io/k8s-artifacts-prod/build-image/kube-cross:v1.14.6-1 - 从香港节点的服务器用Filezilla拉取到本地windows
- 再用Filezilla传到虚拟机,然后
docker load -i kube-cross.tar - 把镜像推送到本地的registry
- docker tag us.gcr.io/k8s-artifacts-prod/build-image/kube-cross:v1.14.6-1 localhost:5000/my-kube-cross:v1.14.6-1
- docker push localhost:5000/my-kube-cross:v1.14.6-1
- Deploy a registry server
-
修改源文件
- vi ./build/build-image/Dockerfile
-FROM us.gcr.io/k8s-artifacts-prod/build-image/kube-cross:KUBE_BUILD_IMAGE_CROSS_TAG +FROM localhost:5000/my-kube-cross:KUBE_BUILD_IMAGE_CROSS_TAG
- vi ./build/build-image/Dockerfile
-
再次运行:

上面的
ERROR: password file must not be other-accessible找了好半天的原因是因为,我是从windows宿主机通过mount把kubernetes的源文件挂载到linux的虚拟机导致的, 解决办法就是拷贝源代码文件到另一个位置不要让源文件被2个系统共享 -
然后又出现如下错误:
Makefile:1: *** missing separator. Stop. !!! [0724 14:29:54] Call tree: !!! [0724 14:29:54] 1: build/../build/common.sh:527 kube::build::run_build_command_ex(...) !!!

还是因为被windows系统打开过导致文件格式出现问题,重新下载kubernetes源码并直接copy到linux系统上,不再被windows系统染指
-
执行
build/run.sh make, 报磁盘空间不足,清理磁盘空间 -

发现系统负载特别大, 调高了虚拟机的配置,升到 8核8G

bash build/run.sh hack/build-go.sh cmd/kubelet, 建议使用:bash build/run.sh make WHAT='cmd/kubelet' - 总结:
- 编译的虚拟机配置要高: 至少8核8G
- 不要通过mount的方式在windows宿主机和编译的linux虚拟机之间共享kubernets源码,会导致rsync出问题
- 不要用windows打开任何文件,可能导致Makefile出现tab键的问题
- 编译时要用到的docker镜像通过别的方式下载下来,放到本地docker就可以了,用不着本地启动registry
