Upgrade a Runtime to a New Version

You can upgrade runtimes to a new Kong Gateway version by bringing up new runtime instances, then shutting down the old ones. This is the best method for high availability, as the new node starts processing data before the old one is removed. It is the cleanest and safest way to upgrade with no proxy downtime.

1. Provision a new runtime through the Runtime Manager:
   • Docker
   • Linux
   • Kubernetes (Helm)

2. Open the Runtime Manager overview. Make sure that your new runtime is up and in Connected status, and that it was last seen Just Now. For example:

   

3. If the new runtime is connected and functioning, you can disconnect and shut down any existing older runtimes that you’re replacing.

   You can’t shut down runtimes from within Runtime Manager.

4. Test passing data through your new runtime by accessing your proxy URL.

   For example, with the hostname localhost and the route path /mock:

    http://localhost:8000/mock
