Amazing idea!

If you want to try a built version you can replace your image with registry.gitlab.com/domiibunn/dockge:latest though it will not be maintained past this pull request

hey, i was just wondering why this hasn't been added to dockge. to me it seems like a great idea that would be very useful when doing my weekly container updates. if you have to click update 50 times on multiple hosts it gets annoying quickly xD

I was so sure this was merged and deleted the branch. I'll make a new MR
