Docker Compose Example of Redundancy and Failover with Nginx

The Nginx configurations described on the page Redundancy and Failover with Nginx can be used in Docker Compose to create an OPC Router redundancy pair with failover.

The files used for this project can be found on the page HTTP(s) failover concepts for REST, OPC UA servers, and WebManagement in the OPC Router .
