在Google Cloud platform上的Kubernetes集群部署HANA Express

在Google Cloud platform的Kubernetes cluster上，新建一个hxe.yaml文件：

将如下内容拷贝进yaml文件：

kind: ConfigMap
apiVersion: v1
metadata:
  creationTimestamp: 2018-01-18T19:14:38Z
  name: hxe-pass

第77行指定了HANA express对应的容器镜像文件：
"store/saplabs/hanaexpress:2.00.033.00.20180925.2"

使用命令行创建资源：

kubectl create -f hxe.yaml:

创建成功，使用命令行kubectl describe pods查看成功创建的资源：

使用命令行查看数据库是否成功启动：

kubectl logs deployment/hxe -c hxe-container
看到startup finished的消息，说明启动成功：

使用命令行进入pod内部，得到shell：

kubectl exec -it <<pod-name>> bash

打开SQL console：
hdbsql -i 90 -d systemdb -u SYSTEM -p HXEHana1
