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 data: password.json: |+ {"master_password" : "HXEHana1"} --- kind: PersistentVolume apiVersion: v1 metadata: name: persistent-vol-hxe labels: type: local spec: storageClassName: manual capacity: storage: 150Gi accessModes: - ReadWriteOnce hostPath: path: "/data/hxe_pv" --- kind: PersistentVolumeClaim apiVersion: v1 metadata: name: hxe-pvc spec: storageClassName: manual accessModes: - ReadWriteOnce resources: requests: storage: 50Gi --- apiVersion: apps/v1 kind: Deployment metadata: name: hxe labels: name: hxe spec: selector: matchLabels: run: hxe app: hxe role: master tier: backend replicas: 1 template: metadata: labels: run: hxe app: hxe role: master tier: backend spec: initContainers: - name: install image: busybox command: [ 'sh', '-c', 'chown 12000:79 /hana/mounts' ] volumeMounts: - name: hxe-data mountPath: /hana/mounts volumes: - name: hxe-data persistentVolumeClaim: claimName: hxe-pvc - name: hxe-config configMap: name: hxe-pass imagePullSecrets: - name: docker-secret containers: - name: hxe-container image: "store/saplabs/hanaexpress:2.00.033.00.20180925.2" ports: - containerPort: 39013 name: port1 - containerPort: 39015 name: port2 - containerPort: 39017 name: port3 - containerPort: 8090 name: port4 - containerPort: 39041 name: port5 - containerPort: 59013 name: port6 args: [ "--agree-to-sap-license", "--dont-check-system", "--passwords-url", "file:///hana/hxeconfig/password.json" ] volumeMounts: - name: hxe-data mountPath: /hana/mounts - name: hxe-config mountPath: /hana/hxeconfig - name: sqlpad-container image: "sqlpad/sqlpad" ports: - containerPort: 3000 --- apiVersion: v1 kind: Service metadata: name: hxe-connect labels: app: hxe spec: type: LoadBalancer ports: - port: 39013 targetPort: 39013 name: port1 - port: 39015 targetPort: 39015 name: port2 - port: 39017 targetPort: 39017 name: port3 - port: 39041 targetPort: 39041 name: port5 selector: app: hxe --- apiVersion: v1 kind: Service metadata: name: sqlpad labels: app: hxe spec: type: LoadBalancer ports: - port: 3000 targetPort: 3000 protocol: TCP name: sqlpad selector: app: hxe
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 <> bash
打开SQL console： hdbsql -i 90 -d systemdb -u SYSTEM -p HXEHana1
