Why am I getting a permission denied error on docker/aws eb?

Question

I don't know why but I cannot seem to figure out why this is happening. I can build and run the docker image locally.

Any help is extremely appreciated.

@nick-humrich suggestion of trying eb local run worked. So using eb deploy ended up working.

I had previously been uploading through the web interface.

Initially using eb deploy was giving me a ERROR: TypeError :: data must be a byte string but I found this issue which was resolved by uninstalling pyopenssl.

So I don't know why the web interface was giving me permission denied perhaps something to do with the zip file?

But anyway I'm able to deploy now thank you.

I had a similar problem running Docker on Elastic Beanstalk. When I pointed CMD in the Dockerfile to a shell script (/path/to/my_script.sh), the EB deployment would fail with /path/to/my_script.sh: Permission denied.

Apparently, even though I had run RUN chmod +x /path/to/my_script.sh during the Docker build, by the time the image was run, the permissions had been changed. Eventually, to make it work I settled on:

CMD ["/bin/bash","-c","chmod +x /path/to/my_script.sh && /path/to/my_script.sh"]
