sudo kubectl run camera -ti --rm --image tekn0ir/camera-http:arm64v8 --generator=run-pod/v1 --overrides='{"spec":{"containers":[{"image":"tekn0ir/camera-http:arm64v8","name":"camera","command":["/bin/bash"],"tty":true,"stdin":true,"imagePullPolicy":"Always","env":[{"name":"BASE_URL","value":"http://192.168.3.101/axis-cgi/jpg/image.cgi?resolution=800x600"},{"name":"USERNAME","value":"root"},{"name":"PASSWORD","value":"teknoir"}]}]}}'

Axis

Find camera

sudo apt-get install avahi-utils
avahi-browse -ltr _rtsp._tcp # Lists all RTSP cameras on the network

The RTSP URL wont work with this app. This app only takes a still image URL.

Create URL

To create a URL for an Axis camera, use the IP and set a RESOLUTION(ex. 800x600) small enough GCP IoT Core max size is 250Kb.

http://<IP>/axis-cgi/jpg/image.cgi?resolution=800x600

Bosch

Create URL

To create a URL for a Bosch camera, use the IP and choose the most appropriate size L (small enough GCP IoT Core max size is 250Kb).

Documentation says:

T-shirt Size	Size in documentation	5000 HD actual size
S (small)	176 × 144/120 pixels (QCIF)	256 × 144 pixels
M (medium)	352 × 288/240 pixels (CIF)	512 × 288 pixels
L (large)	704 × 288/240 pixels (2CIF)	1280 × 720 pixels
XL (extra large)	704 × 576/480 pixels (4CIF)	1920 × 1080 pixels
I have added the atual sizes I got from my Bosch Dinion 5000 HD (NBN-50022-C)

The URL looks like this with T-Shirt Size large:

http://<IP>/snap.jpg?JpegSize=L
