Deploying CAP Application to BTP - Socket

0 Kudos

I have a very basic CAP/CDS application that's more or less a single entity. I am able to test locally using sqlite3 and also hybrid. While testing the hybrid application I've logged into the Hana cockpit and saw my models and data inside the HDI container they were deployed too. I am working locally on my computer, not BAS.

I would now like to deploy this application to BTP so that it will run in CF. I start this process by using the `cds` tool to prepare the mta.yaml and `mbt` to create the MTA archive to deploy to BTP. However, I am not able to properly deploy the archive to BTP. I have using `cds` prepared the project for deployment to a productive environment with `cds add hana`.

Executing task "deploy" on application "test-cds-db-deployer"...
Execution of task "deploy" on application "test-cds-db-deployer" failed.
...
Use "cf dmol -i <hash>" to download the logs of the process.

I see two applications, the server and deployer. There is an HDI container created. Whenever I use the server application to browse the data I receive 503 service unavailable. Upon inspecting the dmol logs:

(STDERR, APP/TASK/deploy)#<br>

This is more or less repeated several times throughout the log. I'm not sure what to actually do from here. While I've seen SSH tunnel suggested, I don't understand how I would setup a tunnel to an application that doesn't exist on CF yet. The deploy application fails to start. Is there somebody that can offer advice?

EDIT: I've also seen advice on whitelisting the IP address I'm deploying from. My IP is whitelisted but the result is the same.

I have the exact same problem, and allowing all IP addresses for the hana database didn't work for me either.

All information I find is either exactly the same or the solutions for the same area/topic are so vastly different that it is hard to apply the information from one example to another.

Here's what is needed. During the process of creating an application and deploying it, many configuration files and folders are created, each and every one of them has a role in deployment. It will be great if there was a simple blog that describes each folder and file in more details than is available currently. This would be helpful to someone who has a programming background but is not familiar with deployment on cloud.
