Using buildkit as sidecar since Docker on EKS is deprecated

[diana-zvulun]

Hi,
We are using docker:dind as sidecar to build our container images inside github actions. Since EKS are deprecating dockershim we are in the process of moving our build process to buildkit instead of docker.
Is there an option to run a sidecar with buildkit image instead of docker:dind image?

I just found out this issue so I guess we are good. Thanks!
