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 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 80:80 ghcr.io/barnstee/ua-clouddashboard:main
