Custom Build

Follow this guide to make custom configurations and build the device service image from the source.

Warning

This is not the recommended method of deploying the service. To use the default images, see here.

Get the Source Code

Clone the device-onvif-camera repository.

git clone https://github.com/edgexfoundry/device-onvif-camera.git

Navigate into the directory
```
cd device-onvif-camera
```
Checkout the latest release (v3.1):
```
git checkout v3.1
```

Configuration

Configure the Pre-Defined Devices

Configuring pre-defined devices will allow the service to automatically provision them into core-metadata. Create a list of devices with the appropriate information as outlined below.

Make a copy of the camera.yaml.example:
```
cp ./cmd/res/devices/camera.yaml.example ./cmd/res/devices/camera.yaml
```
Warning

Be careful when storing any potentially important information in cleartext on files in your computer. Potentially sensitive information in this case could include the IP address of your ONVIF camera or any custom metadata you configure.

Open the cmd/res/devices/camera.yaml file using your preferred text editor and update the Address and Port fields to match the IP address of the Camera and port used for ONVIF services:

Sample: Snippet from camera.yaml

deviceList:
- name: Camera001                         # Modify as desired
   profileName: onvif-camera              # Default profile
   description: onvif conformant camera   # Modify as desired
   protocols:
      Onvif:
         Address: 191.168.86.34           # Set to your camera IP address
         Port: '2020'                     # Set to the port your camera uses
      CustomMetadata:
         CommonName: Outdoor camera

Optionally, modify the Name and Description fields to more easily identify the camera. The Name is the camera name used when using ONVIF Device Service Rest APIs. The Description is simply a more detailed explanation of the camera.
You can also optionally configure the CustomMetadata with custom fields and values to store any extra information you would like.
To add more pre-defined devices, copy the above configuration and edit to match your extra devices.

Configure the Device Service

Open the cmd/res/configuration.yaml file using your preferred text editor
Make sure secret name is set to match SecretName in camera.yaml. In the sample below, it is "credentials001". If you have multiple cameras, make sure the secret names match.

Under secretName, set username and password to your camera credentials. If you have multiple cameras copy the Writable.InsecureSecrets section and edit to include the new information.

Warning

Be careful when storing any potentially important information in cleartext on files in your computer. In this case, the credentials for the camera(s) are stored in cleartext in the configuration.yaml file on your system. InsecureSecrets is for non-production use only.

Sample: Snippet from configuration.yaml

Writable:
LogLevel: INFO
InsecureSecrets:
   credentials001:
      SecretName: credentials001
      SecretData:
         username: <Credentials 1 username>
         password: <Credentials 1 password>
         mode: usernametoken   # assign "digest" | "usernametoken" | "both" | "none"
   credentials002:
      SecretName: credentials002
      SecretData:
         username: <Credentials 2 username>
         password: <Credentials 2 password>
         mode: usernametoken    # assign "digest" | "usernametoken" | "both" | "none"

Additional Configuration Options

For optional configurations, see here.

Build the Docker Image

In the device-onvif-camera directory, run make docker:
```
make docker
```
[Optional] Build with NATS Messaging
Currently, the NATS Messaging capability (NATS MessageBus) is opt-in at build time. This means that the published Docker image does not include the NATS messaging capability. To build the docker image using NATS, run make docker-nats:
```
make docker-nats
```
See Compose Builder nat-bus option to generate compose file for NATS and local dev images.

Verify the ONVIF Device Service Docker image was successfully created:

docker images

REPOSITORY                                 TAG          IMAGE ID       CREATED        SIZE
edgexfoundry-holding/device-onvif-camera   0.0.0-dev    75684e673feb   6 weeks ago    21.3MB

Navigate to edgex-compose and enter the compose-builder directory.
bash cd edgex-compose/compose-builder
Update .env file to add the registry and image version variable for device-onvif-camera: Add the following registry and version information:
```
DEVICE_ONVIFCAM_VERSION=0.0.0-dev
```

Update the add-device-onvif-camera.yml to point to the local image.

services:
   device-onvif-camera:
      image: edgexfoundry/device-onvif-camera:${DEVICE_ONVIFCAM_VERSION}

Additional Configuration

Here is some information on how to specially configure parts of the service beyond the provided defaults.

Configure the Device Profiles

The device profile contains general information about the camera and includes all of the device resources and commands that the device resources can use to manage the cameras. The default profile found at cmd/res/devices/camera.yaml contains all possible resources a camera could implement. Enable and disable supported resources in this file, or create an entirely new profile. It is important to set up the device profile to match the capabilities of the camera. Information on the resources supported by specific cameras can be found here. Learn more about device profiles in EdgeX here.

Sample: Snippet from camera.yaml

name: "onvif-camera" # general information about the profile
manufacturer:  "Generic"
model: "Generic ONVIF"
labels:
  - "onvif"
description: "EdgeX device profile for ONVIF-compliant IP camera."      
deviceResources:
  # Network Configuration
  - name: "Hostname" # an example of a resource with get/set values
    isHidden: false
    description: "Camera Hostname"
    attributes:
      service: "Device"
      getFunction: "GetHostname"
      setFunction: "SetHostname"
    properties:
      valueType: "Object"
      readWrite: "RW"

Configure the Provision Watchers

The provision watcher sets up parameters for EdgeX to automatically add devices to core-metadata. They can be configured to look for certain features, as well as block features. The default provision watcher is sufficient unless you plan on having multiple different cameras with different profiles and resources. Learn more about provision watchers here.

Sample: Snippet from generic.provision.watcher.yaml

name: Generic-Onvif-Provision-Watcher
identifiers:
  Address: .
blockingIdentifiers: {}
adminState: UNLOCKED
discoveredDevice:
    serviceName: device-onvif-camera
    profileName: onvif-camera
    adminState: UNLOCKED
