3.2.4 causing issues with custom docker builds?

[billimek]

No idea if this is related, but I have automated docker builds configured to trigger whenever there is a new gliderlabs/logspout docker image pushed to docker hub.

My image builds from https://github.com/gliderlabs/logspout/blob/master/custom/Dockerfile on docker hub via automated builds. It works on my local, but is failing on docker hub now:

The command '/bin/sh -c cd /src && chmod +x ./build.sh && ./build.sh "$(cat VERSION)-custom"' returned a non-zero code: 2

Given that the error is about ./build.sh: Text file busy I wonder if the change to chmod +x ./build.sh is somehow inexplicably causing this failure?

hrm we build a custom image from the custom/ dir in CI. definitely open to accepting a PR to fix this

I found this which suggests it's a docker hub issue: moby/moby#13594

Investigating a workaround and will PR if necessary or close this issue. Look for a followup from me soon!

#375 created to fix this. The sync alone didn't seem to do the trick, so used a combination of a sleep 1 & sync.

Same issue over here. Merge pls.
