In some cases, you may need to access internal services of the United Manufacturing Hub that are not exposed externally. To do this, you can set up port-forwarding in UMHLens.

ℹ️
The port-forwarding feature is a little bit unstable, so we recommend it only as last resort. If you are using k3d, you can also decide to directly forward these ports to your host machine, so that you can access services using localhost. For installations on edge devices such as flatcar, you can use just the IP of the device.

Instructions

  1. Identify the internal service you want to access. For example, you may want to access the microservice "factoryinsight" or Node-RED when using the k3d or minikube approach.
  2. Go the service you want to access and click on the port

The browser window will automatically open, allowing you to access the internal service. If you want to access something that is not HTTP related (like MQTT), you can copy your local port from the browser URL.

The story of IT and OT - why two systems are better than one
More and more manufacturers are offering their software platforms everywhere on the internet as a panacea for simplifying and optimizing all production processes. But can this really work? Despite the increasing convergence of IT and OT, companies should think twice before using one system to handle both areas. This is because, historically, the vast majority of providers have their roots in either IT or OT. How did this happen, and why does the history of IT and OT make it advisable to separa
