You can have the commands only run during an update by using

pulumi.runtime.is_dry_run()

. You can also put the calls to run

docker

commands inside applies to have them only run once known values are provided. In the JavaScript docket package, I believe both of these are used to build the image every time, but to only push during updates (not previews).

Thanks Luke. I'll give that a go.
