A cross-platform OPC UA cloud dashboard reference implementation leveraging Kafka and MQTT. It runs in a Docker container and displays OPC UA PubSub telemetry data, read directly from a Kafka broker or an MQTT broker. It supports both JSON and binary payloads as well as OPC UA Complex Types decoding.
The following environment variables must be defined:
- BROKER_NAME - the name of the broker to use
- BROKER_PORT - the port number of the broker
- CLIENT_NAME - the client name to use with the broker
- BROKER_USERNAME - the username to use with the broker
- BROKER_PASSWORD - the password to use with the broker
- TOPIC - the broker topic to read messages from
- METADATA_TOPIC - (optional) the broker metadata topic to read messages from
- USE_MQTT - (optional) Read OPC UA PubSub telementry messages from an MQTT borker instead of a Kafka broker
- USE_TLS - (optional) set to 1 to use Transport Layer Security
- IGNORE_MISSING_METADATA - (optional) set to 1 to parse messages even if no metadata was sent for the messages
Run it on a Docker-enabled computer via:
docker run -e anEnvironmentVariableFromAbove="yourSetting" -p 80:8080 ghcr.io/barnstee/ua-clouddashboard:main
