Docker Build failed, /proc file permission denied

[louisgv]

Expected Behavior

Upon pulling new change from master, I should be able to run docker-compose -f local.yml build to update the docker image.

Current Behavior

The build process failed:

Step 8/21 : RUN find . -type d -name __pycache__ -exec rm -r {} \+
 ---> Running in 41c5736fc3df
find: './proc/1/map_files': Operation not permitted
find: './proc/7/map_files': Operation not permitted
ERROR: Service 'base' failed to build: The command '/bin/sh -c find . -type d -name __pycache__ -exec rm -r {} \+' returned a non-zero code: 1

Possible Solution

Steps to Reproduce

1. Pull from master
2. Run docker-compose -f local.yml build

Context (Environment)

After spending an entire day trying all kind of thing to fix the problem, from reinstalling docker, to remove docker tunnel, to reboot my machine a dozen of time, I decided to just comment out the 8th docker command in the base instruction, and that solved the problem.

This was super frustrating. I think this line should be investigated and I think we need to improve it:

RUN find . -type d -name __pycache__ -exec rm -r {} \+

Maybe we can use a python package like pyclean or py3clean to clean up the cache instead of searching for it manually?

I can't reproduce this, but it could be related to moby/moby#16506. Perhaps a PR blacklisting the proc dir may help.

FYI, these packages do the same thing as the script. Just in python instead of bash.

@louisgv I think it's time to close this and #238 unless you can update us with current status and detailed steps to reproduce. Thoughts?

@isms let's close this for now. By commenting out the 8th line of the docker script this problem is gone for me.
