13.5.3. Directory Environment Variables
Directory environment variables return the directories where an application resides. These variables are always available to the application, regardless of which cartridges the application is using.
| Environment Variable Name | Purpose |
|---|---|
OPENSHIFT_HOMEDIR | The home directory of the application. |
OPENSHIFT_DATA_DIR | A persistent data directory. |
OPENSHIFT_REPO_DIR | Repository containing the currently deployed version of the application. |
OPENSHIFT_TMP_DIR | A temporary directory you can use; SELinux protects data in this directory from other users. |
OPENSHIFT_LOG_DIR | Where all cartridge logs are stored. |
Note
Many of these directories are emptied and rebuilt whenever new code is pushed to an application. The only persistent directory is
OPENSHIFT_DATA_DIR. Therefore, Red Hat recommends that you store persistent files in the OPENSHIFT_DATA_DIR directory.
