Add Docker image to Docker Hub automated builds

[jacksegal]

(taken from PR #83 )

At the moment the Docker image is automagically built via Docker Hub automated builds from @djjudas21 Github fork of this project.

Need to set up automated builds from the master repo & then update README with new URL.

@djjudas21 is happy to explain how to do this.

Hi @djjudas21

I've had a go at setting up an automated build: https://hub.docker.com/r/jacksegal/google-compute-snapshot/

Can you have a look and let me know if it's correct? Mine doesn't have the "Dockerfile" or "Builds" tab that yours does.

Thanks,
Jack

It looks OK, I assumed you set it up as an "Automated Build"? If so, you'll need to push a new commit to this repo to trigger an automated build on Docker Hub. Just tweak the readme or something to see if it builds 👍

Thanks @djjudas21 - the last push I did on 7th Jan triggered an automated build on Docker Hub, so I've updated the README with the URL my repo.

Thanks for your contribution 👍

I'm still not 100% sure if this is working properly. On my Docker hub page it shows tabs for Dockerfile and Builds, and on the right hand side there is a link for Source Repository. Yours doesn't have any of those, so does this mean it's a non-automated build?

From what I recall, I didn't create the Docker Hub repo manually, I just followed the wizard to add an automated build, linked it to the Github project and it did the rest itself. Is this what you did?

Also, I spotted in your README it still points people towards my Docker image, rather than yours 😄
