dbus with Greengrass

Hi nhatnhan,

1. I'm not an expert on dbus. Are you trying connect from inside lambda container to the daemon running on bare host? If you are aware of all the devices and volumes required for the connection, you can try mounting those as local resources inside the lambda container. Please attach the error logs if you run into any issues.

2. In general, you can enforce stricter access control in container mode than in process mode. In container mode, you need to explicitly grant lambda access to host resources, e.g. devices, volumes, while in process mode, access to host resources are protected by posix file permissions. However, I wouldn't be too concerned about security if you own both the lambda and the device, since you have full control of the lambda code logic.

Hope this answers your question.

Thanks,
Hui

cool thank you
