If you build and publish a docker image using pulumi, will it also build the docker image during preview? When looking in the logs for my github actions, it looks like it builds the image twice...

unfortunately yes, it's covered by this https://github.com/pulumi/pulumi-docker/issues/132

@billowy-army-68599, thanks... but all I need is probably just to apply the skip preview flag which I had forgot about :)
