如何部署Docker镜像到SAP Cloud Platform

参考SAP官方的帮助文档：https://help.sap.com/viewer/65de2977205c403bbc107264b8eccf4b/Cloud/en-US/c190ad6eeb78428c91a2b66e5557f962.html

第一次尝试，我遇到了下图的错误消息：

You have exceeded your organization’s memory limit: app requested more memory than available
FAILED

要解决该错误，增大该Subaccount的memory quota即可：

第二次尝试遇到的错误消息：

Failed getting docker image manifest by tag: errors:
denied: requested access to the resource is denied
unauthorized: authentication required

登录docker hub，确认使用的docker镜像和tag是否正确：

https://hub.docker.com/repository/docker/i042416/ui5-nginx

最后成功部署：

在SAP云平台上看到成功部署的Docker应用：

拿到应用的url：

可以成功访问了：

我有一个应用部署在SAP云平台上，完整url为：

https://account.hana.ondemand.com/cockpit/#/globalaccount/8c7b2676-8dd1-4a97-bf24-998398f531c2/subaccount/5a9aab80-119b-4371-aa15-43008ebd355f/org/10789717-e078-4d24-bfe0-b5643c67e0e8/space/1e557935-4ec4-4e36-8055-701b27798258/app/5691ae25-0b85-440a-aa92-fb6d2dc317fb/overview

url最后的guid即该应用的guid，可以通过下面的命令行获得：

cf app jerryjavadocker --guid

使用下面的命令行获得该应用的详细信息：

cf curl /v2/apps/5691ae25-0b85-440a-aa92-fb6d2dc317fb > 1.txt

查看route明细：cf curl /v2/apps/5691ae25-0b85-440a-aa92-fb6d2dc317fb/routes

从结果里获得route的guid：4637819d-430f-438f-81f6-8a7742d3027e

再获取该route的明细：

cf curl /v2/routes/4637819d-430f-438f-81f6-8a7742d3027e/route_mappings
