IR800 - Simple docker python app crashes immediately

I'm trying to use the base image found at: iox-docker/ir800/base-rootfs/yocto-2.1.1/ , since it includes python3 support.  Python2 is not an option; I need to use python requests module.  The python2 compiled in the yocto1.7 image does not include contextlib

When I run my app in docker - all is good. Does what it should do. 

I package it using ioxclient, deploy it to an 829, it starts, everything looks fine, but then app stops immediately. 

My dockerfile:

FROM devhub-docker.cisco.com/iox-docker/ir800/base-rootfs:yocto-2.1.1

RUN opkg update && opkg install python-core && opkg install python-pip

RUN /usr/bin/pip install requests

COPY web-relay.py /web-relay.py

RUN chmod 777 /web-relay.py

CMD /usr/bin/python /web-relay.py

Here is container_log_application:

I worked it out

So I fixed my Dockerfile first.  Instead of calling python3 bin, just ran my script directly.  Much cleaner/easier to run.

Then I found the article on how to run ioxclient w/ debug (NOTE: on my client, if I do

ioxclient application activate <name> --debug

it fails

ioxclient application activate <name> -debug

Works.

YAY I'm excited!

Hello, @Levi Iiams 

I know it's been a couple of years now but I am facing the exact same issue, the only thing is that I don't understand what you did to solve the problem, do you remember?
