Search available images in container registry when deploying from settings

[codegoblins]

I'd like to see some integration with container registries to make deploying images easier for the end user.

The way I see this feature breaks down to 2 tasks:

• Add an endpoint to the backend to fetch a list of public images from a configured container registry endpoint. Ideally supporting multiple container registry providers (we use Quay.io but I know a lot of people use Docker's offering).
• Add a widget to the deploy from settings page to search the offered images and let the user select the desired image. This could be an auto-complete on the container image text box, or a button adjacent to the text box opening a selector modal.

We were planning to add autocomplete and some support for docker, and possibly other providers but there were many other things to do and polish before release. I believe this will be implemented at some point. Maybe even in the next release. We'll know more after next planning.

@codegoblins Sounds just about right. I think if you have spare cycles, it is ready to be implemented. We've been planning such feature anyways :)

Are you taking this?

[codegoblins]

Sure, I will take this.
