Repo layout
wsgi/ - Externally exposed wsgi code goes
wsgi/static/ - Public static content gets served here
libs/ - Additional libraries
data/ - For not-externally exposed wsgi code - Standard, specify deps here
../data - For persistent data (also env var: OPENSHIFT_DATA_DIR)
.openshift/action_hooks/pre_build - Script that gets run every git push before the build
.openshift/action_hooks/build - Script that gets run every git push as part of the build process (on the CI system if available)
.openshift/action_hooks/deploy - Script that gets run every git push after build but before the app is restarted
.openshift/action_hooks/post_deploy - Script that gets run every git push after the app is restarted
Environment Variables
OpenShift provides several environment variables to reference for ease
of use. The following list are some common variables but far from exhaustive:
os.environ['OPENSHIFT_APP_NAME'] - Application name
os.environ['OPENSHIFT_GEAR_DIR'] - Application dir
os.environ['OPENSHIFT_DATA_DIR'] - For persistent storage (between pushes)
os.environ['OPENSHIFT_TMP_DIR'] - Temp storage (unmodified files deleted after 10 days)
When embedding a database using 'rhc app cartridge add', you can reference environment
variables for username, host and password:
os.environ['OPENSHIFT_DB_HOST'] - DB host
os.environ['OPENSHIFT_DB_PORT'] - DB Port
os.environ['OPENSHIFT_DB_USERNAME'] - DB Username
os.environ['OPENSHIFT_DB_PASSWORD'] - DB Password
To get a full list of environment variables, simply add a line in your
.openshift/action_hooks/build script that says "export" and push.
Notes about layout
Please leave wsgi, libs and data directories but feel free to create additional
directories if needed.
Note: Every time you push, everything in your remote repo dir gets recreated
please store long term items (like an sqlite database) in ../data which will
persist between pushes of your repo.
Notes about
Adding deps to the install_requires will have the openshift server actually
install those deps at git push time.
