Build | automation improvement

[exequielrafaela]

What?

Improve current Docker hub build / push automation (https://hub.docker.com/repositories) to avoid wrong tags in images.

Why?

• If you change the code and do not manually change the build setup (each time) at Docker Hub (eg: https://hub.docker.com/repository/docker/binbash/terraform-resources/builds/edit) this error could be repeated
• That manual step is unfortunately very error prune, to reduce the toil to the minimum we would have to upgrade to a fully automated as code with CircleCI Approach.
• This could affect several projects that depends on this images.

How?

We'll follow https://docs.github.com/en/actions/language-and-framework-guides/publishing-docker-images#publishing-images-to-docker-hub

Reference example below

name: Publish Docker image
on:
  release:
    types: [published]
jobs:
  push_to_registry:
    name: Push Docker image to Docker Hub
    runs-on: ubuntu-latest
    steps:
      - name: Check out the repo
        uses: actions/checkout@v2
      - name: Push to Docker Hub
        uses: docker/build-push-action@v1
        with:
          username: ${{ secrets.DOCKER_USERNAME }}
          password: ${{ secrets.DOCKER_PASSWORD }}
          repository: my-docker-hub-namespace/my-docker-hub-repository
          tag_with_ref: true

Consideration

We could temporally handle it as it is with strict attention and to be address during 2020 Q4.
