Offline standalone app build

GolamGauseJaman

Due to various network restrictions, I struggled l to get the camera talk to the Internet. I was trying to build the app using docker but may not be creating the correct docker file from the .toml. I am searching for any documentation or instructions on how to build the app locally without the camera connected. SCP the .oakapp to camera later or something followed by installation and run. Any example or process steps are greatly appreciated. Advanced apology if I made the question confusing.

Camera: OAK4D Pro

Luxonis OS 1.27.1

Oakctl agent 0.18.3

Hey GolamGauseJaman - oakapp.toml is the app definition, so you normally do not turn it into a Dockerfile yourself.

For OAK4 apps, the documented workflow is that oakctl sends the app to the camera and the build happens on the device through oak-agent. After that you can download the resulting .oakapp package and install that same package on another camera later. So the general idea of “build once, then install later” is correct, but the usual path is oakctl app install, not manual SCP. More on this can be found in our docs here.

If your goal is to avoid Hub/cloud, that part is fine too: oakctl works with OAK4 devices over the local network via the preinstalled oak-agent, so a local/offline-style workflow is possible. The main limitation is that the build still happens on the device, so if your app build needs internet for base images, pip, npm, or model downloads, you would still need either internet access, a local registry/cache, or prepackaged dependencies.

Thanks,
