Feature Request: Docker Pull

[Norien]

I'd love to have a button in home assistant which would pull the lastest image for some of my containers. Do you think it would be possible to add a curl command much like the restart?

Hey @Norien absolutely!

I have a few ideas floating in my head to do this. I've been meaning to get around to it. My end goal is to have a one-click script in Home Assistant that takes down HASS, does a docker pull, then brings it back up with the new version running.

So, watch this space!

I use watchtower to have dockers images upgraded automagically

@elRadix haven't used WatchTower, but agree that would be an alternative.

My current plans are a basic docker pull support, allowing Home Assistant to fire of a REST call, which will upgrade the image, then stop the Home Assistant container, remove it, and re-create a new one with the latest image.

Very similar to what WatchTower does, but with the added bonus of being a button inside Home Assistant.

@philhawthorne
It's same thing what Watchtower does (remove it, and re-create a new one with the latest image) with added bonus that you'll get a notification whenever an image is updated.

Having a manual button might be great, but then you need to know when to push it if there in upgrade available for each image...

Absolutely 😸

If people are already running HA-Dockermon, users don't have to then run WatchTower as well. The manual button might also be good, if users would like to skim the release notes for breaking changes first.

Otherwise, people could use the updater component in Home Assistant to fire off a REST call to HA-Dockermon to upgrade the image. Either at a certain time each day, or when the update is detected in Home Assistant.
