ERRO[0605] Can't add file <some_file> to tar: io: read/write on closed pipe

I have been trying to deploy for about 48h now and still no luck so I don’t think this is due to a temporary issue.

Whenever i run fly deploy --remote-only I get a ERRO[0605] Can't add file <some_file> to tar: io: read/write on closed pipe error.
My app is in fra with ams and cdg as backup.

Here is a log with some more information:

Cna you check the size of the files you’re uploading? It’s possible you’re uploading a file that should be created by the build.

du -shx * | sort -rh | head -n 10 will show you the top 10 larges files/dirs.

Adding the offending file/directory to .dockerignore can help, if you find anything.

Thanks for your help Joshua!

I did notice a few files that needed to be added to my .dockerignore but it unfortunately didn’t help.
Furthermore, I had no problem with big files in the past and I haven’t added new ones recently.

However, I am currently on holiday with a rather slow internet speed. Could it be the culprit?

Actually, you put me on the right track. I switch to a 4G connection on my phone and because the upload speed was faster, the deploy succeeded.

Thank you!

Glad to hear it! If you don’t mind, could you paste the output of your successful build?

Sure thing! Can I ask what you are interested in looking at?

Thanks!

I suspected that you did not have buildkit enabled. This is the newer, more efficient way to build Docker images. We’ve seen problems like this in the past when it was disabled. I recommend using it for all your builds.

To enable it, just make sure DOCKER_BUILDKIT is set to any value in your shell environment.

More info here: Build images with BuildKit | Docker Documentation

Oh great I’ll add that to my deploy scripts right away.

I actually read that you recommended this in another thread, but I thought it had been enabled by default.
