The following prerequisites apply:
Update docker-compose.yml for all services
For all nodes that you shall add, you must do changes in docker-compose.yml for all services. Make sure that all service names are different for every node and that they match the ones you set in Digital Access Admin while adding the new services. See the examples below.
In Digital Access Admin
