当通过K8S从私有仓Harbor中拉取镜像时，报错：
Failed to pull image "harbor.paicidata.com/crawler/dataetl_sit:v0.0.3": rpc error: code = Unknown desc = Error response from daemon: pull access denied for harbor.paicidata.com/crawler/dataetl_sit, repository does not exist or may require 'docker login'
提示：docker未登录 或者 镜像不存在，直接通过docker pull命令去执行是可以的，看来是K8S认为docker未登录。
报错信息
涉及到在deployment中添加imagePullSecrets：拉取镜像授权。
通过kubectl create secret创建一个secret然后引之~
kubectl create secret docker-registry regsecret --docker-server=harbor.paicidata.com --docker-username=admin --docker-password=xxxx --docker-email=xxxx
追加imagePullSecrets即可：
apiVersion: extensions/v1beta1
kind: Deployment
