Install NodeRED for Plant Applications Releases Earlier than SP1

Update the gateway-service-prod.properties file in the following location: {{installation path }}/PlantApplicationsDocker/plantapps-web-docker/mnt/configfiles/gateway-service/prod/{{version}}/.

Verify that the NodeRED path already exists. If the NodeRED path is not available, then update the path by adding the following:

Restart Gateway service by typing the following commands:

docker service scale PAGatewayService_gateway-service=0docker service scale PAGatewayService_gateway-service=1

Update the haproxy.cfg file in the following location: {{installation path }}/PlantApplicationsDocker/plantapps-web-docker/mnt/paweb/config/.

Add the following configuration:

use_backend gatewayServiceBackend if {
                        path -i -m reg -i ^[^\.]*-nodered-app }

Restart the Haproxy service by typing the following commands:

docker service scale PAHaproxy_haproxy=0docker service scale PAHaproxy_haproxy=1
