Kong entities change management

Hi,
Maybe i’m missing the documentation but what is the best practice for updating Kong services/routes/plugins automatically, in the CI/CD process, without the need of manual intervention.

Use case:
Lets say i have kong deployed on 3 environments and i want to release a change gradually from env to env (dev > prd)
a change can be something like adding a service/route, updating a service/route, changing plugin configuration etc.

Im looking on how to rollout these changes and apply them automatically (kind of a change management)

Regards,
Lior
