13.6. Hot Deployment

When the git push command is run to upload code modifications, OpenShift Enterprise stops, builds, deploys, and restarts an application. This entire process takes time to complete and is unnecessary for many types of code changes. With hot deployment the changes to application code are applied without restarting the application cartridge, resulting in increased deployment speed and minimized application downtime.

OpenShift Enterprise provides support for hot deployment through a hot_deploy marker file. If the marker is present, supported application cartridges automatically hot deploy when the git push command is executed.
