Outdated buildkit version on newer cloudformation stacks

[jaimebarriga]

Describe the bug

We recently upgraded our Cloudformation stack from 6.21 to 6.30 to be able to get this update which upgrades buildx to 0.15 so that we can get buildkit v0.14. We did this as we were affected by the buildkit cache issue this PR was attempting to fix.

I upgraded, however I am still seeing the buildkit caching issue. Did some digging and found that the BuildKit version is still an older version (0.12.5) even though I could confirm that we were now using buildx v0.15

From an older instance (Stack version: v6.21)

Attempts to Fix

I tried getting around this by creating my own builder and using that as a default

docker buildx create --name custombuilder --driver docker-container --driver-opt image=moby/buildkit:v0.14.0 --use
docker buildx inspect custombuilder --bootstrap

When running this manually it works

> docker buildx ls

However, if I added this exact same code in my bootstrap script, it runs (I checked the logs), but when I SSH into the instance and check the builder, there is no trace of my custombuilder

Any ideas how I can fix this?

Expected behavior

Actual behaviour
It is instead v0.12.5

Thanks @jaimebarriga, that's confusing. I'll try to replicate and get back to you.

Hi @DrJosh9000, have you been able to replicate?
