Unable to build/deploy as CloudFoundry app on IBM Cloud

[oosawak1975]

To whom it may concern,
We are trying to deploy an Swift app as CloudFoundry on IBM Cloud. When we contain Kitura-OpenAPI and Kitura-CouchDB, it fails due to 2GB disk space limitation of CloudFoundry. We tried the SWIFT_BUILD_DIR_CACHE: false setting in manifest file, but no luck. Also, 2GB disk space seems to be a hard limit. Is there any workaround to build and deploy?

The df command shows:

However if we add the below dependencies

Kitura-OpenAPI located at https://github.com/IBM-Swift/Kitura-OpenAPI.git
Kitura-CouchDB located at https://github.com/IBM-Swift/Kitura-CouchDB.git

The application fails with the below error:

Unfortunately I think this is a known issue - see: IBM-Swift/swift-buildpack#123

I doubt that the Kitura-OpenAPI project is at fault here, likely the additional libraries that it pulls in are just enough to cause the Swift build to exceed the file system limit.
