How to SSH to an Azure IoT Edge Device with no inbound port open?

Question

Hi,

We were wondering...

1) How to SSH to an Azure IoT Edge Device with no inbound port open?

2) Are there any SSH tunneling capabilities, as the ones presented by IoT Hub device streams, provided for IoT Edge Devices?

3) How should we add the support for this?

Best regards,

Amparo

Hi APittier,

As far as my knowledge you cannot SSH to an Azure IoT Edge Device with no inbound port open nor using device streams but I am researching internally and will get back to you with more certain. If this is a new feature request I will point you to open a new request under Azure IoT Edge Feedback Hub.

Thanks!

Hi again,

Good news, I received confirmation that it is now possible to use Edge proxy as an IoT Edge module that enables end-to-end connectivity to your Edge device using device streams. 

See the following repo to set up edge proxy for trial purposes:

https://github.com/rezasherafat/edge-proxy/

Note: This module is not yet officially supported therefore don't use it in production.

Thanks!

Thanks so much! worked great for me.  Used it for a raspberry pi had to rearrange the docker file to get it working on the Edge on an RPi.
