OPC Publisher is ready to be used as a module to run in [Azure IoT Edge](https://docs.microsoft.com/en-us/azure/iot-edge) Microsoft's Intelligent Edge framework.
|
||||
We recommend to take a look on the information available on the beforementioned link and use then the information provided here.

* OPC Publisher will write diagnostic information each 60 seconds to the console (`--di=60`).
|
||||
* The log file `publisher-publisher.log` (default name) will be written to `/appdata` and the `CertificateStores` directory will also be created in this directory.
|
||||
* OPC Publisher will trust the OPC servers it connects to (`--aa`) will put its own public certificate into the `CertificateStores/trusted/certs`(`--to`) and will send if any value of the published configured nodes changes, immediately a message to IoTHub (`--si=0 ---ms=0`).
|
||||
* Port 62222 of the container will be exposed to the host system. This is the port on which OPC Publisher's integrated OPC UA server listens. So you can connect with an OPC UA client and call OPC UA methods to configure the nodes to (un)publish.

* Port 62222 of the container will be exposed to the host system because of the `ExposedPorts' configuration. This is the port on which OPC Publisher's integrated OPC UA server listens. So you can connect with an OPC UA client and call OPC UA methods to configure the nodes to (un)publish.
|
||||
* The `ExtraHosts` configuration enables the container's network stack to do hostname name resolution even without DNS. (Note: on Windows hosts this is essential to configure)
|
||||
On my system with the hostname `opctestsvr` and the IPv4 address `192.168.178.26`i run a OPC UA server and my pn.json which i have put in `d:\iiotedge` has the following content:
