[Feature] Update entity that uses webhooks

[dd310]

Is your feature request related to a problem? Please describe.

It would be nice to have a way to monitor the availability of a new image for a stack/container and trigger the update from Home Assistant.

Describe the solution you'd like

I don't know if it's feasible, but maybe it could be possible to introduce an update. entity in Home Assistant that senses whether or not there is a new image available and sends a POST request to a specific stack webhook, triggering the image pull and the stack re-deployment.

As far as I know, docker in not aware of available update. You normally have to use watchtower.

Currently I'm using WUD (https://github.com/fmartinou/whats-up-docker) and mqtt to receive a notification on HA when a new image is available. However, since it does not integrate with Portainer API, i still have to log in the instance and re-deploy manually.

I noticed there's a little dot next to the stack name in the portainer GUI that turns red when an image update is available, but I can't say if it could be useful.

EDIT

Searching online i found that the endpoint stacks/<stackID>/images_status should report the state of the images as either "updated" or "outdated"

sure, I can check that

Any update in this?

No, I will be looking at it when I will be working on next feature update for this integration.
