How to create a directory on my cloudfoudry account?


Tag: lucene,cloud,command-line-interface,cloudfoundry

I deploy to cloudfoundry an application which need a directory for lucene. This application failed to start because there is not the configured directory. I search on Cloundfoundry forums but i did not found how to create a directory on my server on CloudFoundry. If someone have a documentation or already did it, it will help me. Thanks

Cloudant provides Lucene indexes to users. Also Cloudant has a pretty big free tier.
