K8S+Cloud-Controller-Manager对接Openstack Cinder创建PV之一:编译cloud-provider-openstack
1、编译环境
作者：vxlinux2019
编译环境为ubuntu环境，可以连接外网
2、下载源代码# mkdir /root/gopath/src/k8s.io
# cd /root/gopath/src/k8s.io
# git clone https://github.com/kubernetes/cloud-provider-openstack.git
# git checkout -b remotes/origin/release-1.17
3、设置编译环境
3.1、安装go
参考：基于go编译环境编译virtual-kubelet用于kubernetes对接openstack-zun
3.2、设置编译环境变量# export GOROOT=/opt/go
# export PATH=$PATH:$GOROOT/bin
# export GOPATH=~/gopath
4、编译
# cd cloud-provider-openstack
# make build
编译好的版本就在当前目录下
~/gopath/src/k8s.io/cloud-provider-openstack# ls -l

5、问题
编译过程中会出现如下问题：
build command-line-arguments: cannot load github.com/container-storage-interface/spec/lib/go/csi: github.com/container-storage-interface/spec@v1.2.0: Get https://proxy.golang.org/github.com/container-storage-interface/spec/@v/v1.2.0.zip: dial tcp 172.217.24.17:443: i/o timeout
Makefile:60: recipe for target 'cinder-csi-plugin' failed
make: *** [cinder-csi-plugin] Error 1
go: downloading github.com/gorilla/mux v1.7.3
build command-line-arguments: cannot load github.com/gorilla/mux: github.com/gorilla/mux@v1.7.3: Get https://proxy.golang.org/github.com/gorilla/mux/@v/v1.7.3.zip: dial tcp 172.217.27.145:443: i/o timeout
Makefile:72: recipe for target 'k8s-keystone-auth' failed
make: *** [k8s-keystone-auth] Error 1
go: downloading github.com/kubernetes-csi/csi-lib-utils v0.6.1

Makefile:96: recipe for target 'manila-csi-plugin' failed
make: *** [manila-csi-plugin] Error 1
这些问题的原因都一样，都是外部网络连接失败
dns每次解析的proxy.golang.org地址可能不同，有些地址能通，有些地址会超时，
多尝试几次能够编译通过
