Hey community, any help or leads would be greatly appreciated!

I’m encountering a size validation error when building Docker images with BuildKit in our CI runners which is Kubernetes-based GitHub Actions self-hosted runner environment. The same build succeeds on my local machine.

I cant seem to find a solution that works for me, when i disable buildx, it is successfully able to build the image.

ERROR: failed to solve: failed to compute cache key: failed commit on ref "layer-sha256:18de230890be85801ad24c37f353e88a3f92aec509b587429850816146fb42cd": "layer-sha256:18de230890be85801ad24c37f353e88a3f92aec509b587429850816146fb42cd" failed size validation: 5063527168 != 4294967295: failed precondition
Error: Process completed with exit code 1.

Any leads on how I can address this issue ?

Hey, do you know what storage driver or filesystem your runner’s using?? Looks like it’s hitting a 32 bit size limit.
