OAK4 running `runc` containers howto

Simple question.

There is mention on this page (https://docs.luxonis.com/software-v3/oak-apps/oakctl/) for using runc containers. I don't see much beyond that on how to set this up on a camera. Is there a specific example somewhere?

Hi @JeremyA
The agent uses runc under the hood. The user is never meant to interact with it directly.
For examples, check https://docs.luxonis.com/software-v3/oak-apps/ and https://docs.luxonis.com/software-v3/template/

Hi @jakaskerl

That helps a lot. There is mention of gcc build tools but all examples use python. Are there any examples using C++?

No not, yet. The development of c++ programs is supported, but quite painful currently as there is no way to attach to the container and making changes means rebuilding+recompiling the whole thing.

Attach function is supposedly planned for EOW.

Thanks,

jakaskerl To be clear, you mean this should be easier by end of the week when we can attach?

Is there a target version of OAK4 firmware or oakctl that we should look for?

Hi JeremyA

Yes. Because you can try the steps without having to rebuild each time.

JeremyA Is there a target version of OAK4 firmware or oakctl that we should look for?

I can't say for sure. We need to release an OS update as well. I can send you the release candidate when we push the changes so you don't have to wait for the full release.

Thanks
