Auto Build docker image nightly

[ryanmerolle]

Would you be open to autobuilding using something like below? I am happy to create a PR.

.github/workflows/build.yml

name: build

concurrency:
  group: build-${{ github.ref }}
  cancel-in-progress: true

  push:
    branches:
      - 'master'

      - '*'
    paths-ignore:

  pull_request:
    branches:

Yes, please!

Same as https://github.com/librenms/docker/discussions/377#discussioncomment-6515401. See for example the issue we currently have with arm/v6 arch: https://github.com/librenms/docker/pull/362. We can't blindly build HEAD and hope it works.

Also we are already testing master branch in one of our workflow: https://github.com/librenms/docker/actions/runs/5629776927/job/15255117247

If you want to be on edge you can build the image yourself:

$ docker buildx bake image --push --set "*.tags=user/repo:latest"
