k8s部署spinnaker完不能创建servergroup

问题：采用helm安装spinnaker，部署成功，最终发现并不能创建servergroup。
分析：查看clouddriver的启动日志，报找不到/root/.kube/config文件
解决：把集群的admin用户的.kube/config打到clouddriver镜像里，亦或者创建新的用户给spinnaker使用。
注意：问题解决后，创建pipeline的时候找不到dockerhub下的镜像去触发。这个时候需要把镜像仓库地址镜像名注册到clouddriver配置文件中。如：

	clouddriver-local.yml:
	
	server:
	  port: ${services.clouddriver.port:7002}
	  address: 0.0.0.0
	
	default:
	  account:
	    env: ${providers.kubernetes.primaryCredentials.name}
	
	kubernetes:
	  enabled: true
	  accounts:
	    - name: default
	      serviceAccount: true
	      providerVersion: v1
	      dockerRegistries:
	        - accountName: dockerhub
	
	dockerRegistry:
	  enabled: true
	  accounts:
	    - name: dockerhub
	      address: https://registry.gcloud.srcb.com:443
	      insecureRegistry: true
	      
	      repositories:
	        - cloudpi/potal-frontend
	        - cloudpi/potal-backend
	      
	credentials:
	  primaryAccountTypes: ${providers.kubernetes.primaryCredentials.name}
	  challengeDestructiveActionsEnvironments: ${providers.kubernetes.primaryCredentials.name}

或者在spinnaker value传参文件里传进去。如：

	accounts:
	- name: dockerhub
	  address: https://registry.gcloud.srcb.com:443
	  insecureRegistry: true
	  repositories:
	    - cloudpi/potal-frontend
	    - cloudpi/potal-backend
