Docker Compose example for Redundancy failover with Nginx

The Nginx configurations described on page Redundancy failover with Nginx can be used in Docker Composer to create an OPC router redundancy pair with failover.

The files that are used as a project can be found on the HTTP(s) failover concepts for REST, OPC UA Server & WebManagement in the OPC Router page.
