Using the docker provider, how can I make pulumi only destroy and recreate the container if the image is actually updated?
I've tried doing it like this:
Copy code
const registryImage = docker.getRegistryImage(
  {
    name: "meisnate12/plex-meta-manager",
  },
  dockerProviderOpts
);

const image = new docker.RemoteImage(
  name,
  {
    name: "meisnate12/plex-meta-manager",
    pullTriggers: [
      registryImage.then((registryImage) => registryImage.sha256Digest),
    ],
  },
  dockerProviderOpts
);
But it still wants to update the image every 
pulumi up
, if I select 
details
it shows this:
Copy code
image: "sha256:9bf92ccb981db90633aef0366ba0d4cc3ee9f50d8d9f2b25599f7e84eeb355fc" => "meisnate12/plex-meta-manager"

If you are using it in a CI/CD environment, you can use the Git SHA for tagging the image. This way you can ensure that replacement only happens when there is a new image.

Hey, thanks! Isn't that what I'm doing in the pullTrigger?

I haven't really tried with pull triggers, my current way is tag image with the Git SHA, so your case would be something like 
meisnate12/plex-meta-manager:#{GIT_SHA}#
, so in pipeline, if there is no new commit, Git SHA remains the same and it won't cause building of new image and replacement of image for pods in K8s cluster (for my case)

Oh, this isn't my image, so I'm not building/tagging it
