Does buildkit support --pull Always attempt to pull a newer version of the image

[lugeng]

Question:
As i know when I use old 'docker build', it has args like "--pull",it will always pull new base image in case the base image is overwrite remotely.
Does buildctl owns such args?

buildkitd with oci worker always checks that the remote image is current by default. With containerd worker, if you have a local image in containerd image store but you want to ignore it, you can use --opt image-resolve-mode=pull

when use BUILDKIT=1 ; we found --pull is an illegal option. buildkit will use old image in build FROM image. this confuse me many times.
any solution for docker build --pull with buildkit ?? @tonistiigi
