To enable app development in Open OnDemand (OOD) a sandbox directory must be provisioned.
First, we need to allow the user to create sandbox apps by creating a symlink to point to the homedir:
sudo mkdir -p /var/www/ood/apps/dev/<USERNAME> cd /var/www/ood/apps/dev/<USERNAME> sudo ln -s /home/<USERNAME>/ondemand/dev gateway
Once complete, the enabled user can try a tutorial e.g. https://osc.github.io/ood-documentation/latest/tutorials/tutorials-interactive-apps/add-jupyter/copy-app.html to become familiar with the sandbox environment and the steps to clone an app from a repo.
https://openondemand.org/run-open-ondemand#enabled-applications is a catalogue of OOD apps available.
