git hash should be fairly straightforward as it’s locally static, is the issue that you want to get a deployment time only when changes happen?

Yes - i want the "version" of the webapp to be shown in a developer-debug-info view as well as when the service was deployed last. the issue being that the webapp doesn't change everytime i redeploy my stack, so it should only be the specific ressource

thinking out loud, I think that likely wants to be set inside the container rather than at the deployment, the deployment time information doesn’t really have the metadata ability to set values that way. I’ll keep considering if there’s a way to solve

thanks. it's also a nice to have of sorts.

yeah I think that’s gonna be easier

My solution for getting the build time of a docker image, ended up being:

def get_build_time(self, image: docker.Image) -> Output[datetime | None]:
        cmd = command.local.Command(
            f"{image._name}-build-time",
            create='TZ=UTC date +"%Y-%m-%d %H:%M:%S"',
            triggers=[image.repo_digest],
            opts=pulumi.ResourceOptions(parent=image),
        )

        def to_datetime(stdout: str) -> datetime | None:
            if not stdout.strip():
                return None

            return datetime.strptime(stdout.strip(), "%Y-%m-%d %H:%M:%S")

        return cmd.stdout.apply(to_datetime)

In theory i could add the git hash in a similar way
