I have a Pickle object in django_app/content_classifer object. There is a class to predict the result and it's initializing itself when celery tasks file gets initialised.

docker build keeps failing after giving an error message as in the title.

Answer 1

if you are on Mac, make sure docker desktop is running

Can't believe I fell for this! 😝 – Glasswork

Simultaneously felt dumb and relieved after seeing this 🤣 – Glassworks

You mean Docker Desktop right? Whether or not the docker hub website is running is out of my control. – Eanes

In my case I had to close and reopen it :) – Naturalize

Please also explain the error message and how you figured out this was the problem. – Sandblind

Answer 2

I had same issue few minutes ago, when I found your issue :) I had some files opened = they were used by another application(GIT)

Please make sure that no files are being used.

Hope it will help.

Thanks, a debugging session was still active. – Meier

THANKS! And in my case - they were opened (and being debugged) in Visual Studio. Grrr. I'm feeling pretty dumb... – Paling

Answer 3

I had this problem in Ubuntu and sudo service docker restart fixed it

Answer 4

The problem faced because the process that generates the pickle object has a diffrent user assigned then process that was accessing the pickle object.

I define the location for pickle object in the setting file.

picklefile = "usr/local/webapp/forest.pickle"

I simply added the step as following in Dockerfile.

RUN chown -R /user/local/webapp/

Where I can find the setting file? – Satterwhite

Answer 5

I had the same problem. If you are using Docker on Windows using Docker Toolbox you should first run the Docker Quickstart Terminal, otherwise, it will not work. Hope this helps someone!

Answer 6

For me when I was running it with WSL 2, I just had to add sudo to the docker command and it was all good.

Answer 7

It seems that this is an Input/Output error and the docker couldn't access the files it wants to. As suggested by @Luk3rson make sure that the files are not used by any other application. Try to debug the logs in /var/log/. May it help you.

Answer 8

I had a similar error when I was using a Docker context for a remote Docker host. After reverting to the Docker daemon on my local machine (Linux) everything worked again.

Answer 9

Restart your docker hub if you are on Mac. Docker was already running but restarting it did the trick for me.

Use this command to give permissions
