Installing Kong with Docker (Hybrid Mode)

Introduction In this article we will deploy Kong Gateway 3.10 open source in Hybrid mode using Docker Compose. This architecture, based on the separation between the Control Plane (CP) and the Data Plane (DP), is one of the deployment models recommended by Kong for API Gateway environments because of its flexibility, scalability, and high availability. In a Hybrid deployment, only the Control Plane maintains a direct connection to the database and is responsible for managing the full gateway configuration through the Admin API and Kong Manager. The Data Planes, on the other hand, run in DB-less mode and automatically receive configuration from the Control Plane through a secure channel protected by mTLS. This allows the Data Planes to keep processing traffic even if the Control Plane or the database becomes temporarily unavailable.
