This was working fine until recently, I’ve tried previous image tags, and it doesn’t work either.
This simple Dockerfile fails to build now:
FROM nixos/nix RUN mkdir /app
I thought maybe
/app had become protected by Fly or something, but any variant still fails:
FROM nixos/nix RUN mkdir /blah
Some more notes: running this on a local Docker daemon works fine. Other images work fine:
FROM alpine RUN mkdir /app
So it’s something specific to this image. I’ve also tried deleting the remote builder and using a new one, but that did not help.
=> ERROR [2/2] RUN mkdir /app 0.4s ------ > [2/2] RUN mkdir /app: ------ Error failed to fetch an image or build from source: error building: executor failed running [/bin/sh -c mkdir /app]: exit code: 139
Any ideas what’s happening? Thanks for the help.
