Modify configuration​

In examples/rtspDeviceShifu/camera-deployment/deviceshifu-camera-deployment.yaml:

spec:

  template:
    ...
    spec:
      containers:
      ...
      - image: edgehub/camera-python:v0.0.1
        ...
        env:
        - name: EDGEDEVICE_NAME
          value: "edgedevice-camera"
        - name: EDGEDEVICE_NAMESPACE
          value: "devices"
        - name: IP_CAMERA_ADDRESS
          value: "192.168.14.254" # change this value
        - name: IP_CAMERA_USERNAME
          value: "admin" # change this value
        - name: IP_CAMERA_PASSWORD
          value: "password" # change this value

::: Recommend using Secret to store passwords, which is not necessary for access devices, but this will greatly enhance security

  1. Create a Secret with rtsp_password field filled by your password.
kubectl create secret generic deviceshifu-secret --from-literal=rtsp_password=your_password -n deviceshifu
  1. Modify the yaml file above, change the value of enviroment varible IP_CAMERA_PASSWORD from string to Secret we just created.
- name: IP_CAMERA_PASSWORD
  valueFrom:
    secretKeyRef:
      name: deviceshifu-secret
      key: rtsp_password
      optional: false

tip

To check the ip address of your camera, use the official tool provided by Hikvision:

SADP

Deploy deviceShifu​

Run the following command:

kubectl apply -f examples/rtspDeviceShifu/camera-deployment

Interact with deviceShifu​

In examples/rtspDeviceShifu/camera-deployment/deviceshifu-camera-configmap.yaml:

data:
  ...
  instructions: |
    ...
    instructions:
      capture:
      info:
      stream:
      move/up:
      move/down:
      move/left:
      move/right:

You can use these instructions to interact with the deviceShifu, which is equal to operate on the actual Hikvision camera.

Accessing the camera via browser​

We can access the pod through service, we have set the corresponding service in the default yaml file, now we just need to use it to enable port forwarding

Get the current list of services with the following command 

kubectl get svc -A

The service that has been around for the shortest time is the one we just added, and we can enable port forwarding with the following command

kubectl port-forward -n deviceshifu svc/<fill in the name of the service we just added> 3000:

If it runs smoothly we can see the following output

Forwarding from 127.0.0.1:3000 -> 8080
Forwarding from [::1]:3000 -> 8080

Then you can access the camera from the browser For example, accessing localhost:3000/info should display information about the camera Replace info with another instruction to achieve the corresponding function
