# This is a GitLab CI configuration to build the project as a docker image
# The file is generic enough to be dropped in a project containing a working Dockerfile
# Author: Florent CHAUVEAU <florent.chauveau@gmail.com>
# Mentioned here: https://blog.callr.tech/building-docker-images-with-gitlab-ci-best-practices/

# do not use "latest" here, if you want this to work in the future
image: docker:19.03.0-dind

stages:
  - build

# Use this if your GitLab runner does not use socket binding
services:
  - docker:19.03.0-dind

variables:
  DOCKER_HOST: tcp://localhost:2375
  DOCKER_TLS_CERTDIR: ""

.docker-script-before: &docker-script-before
  # docker login asks for the password to be passed through stdin for security
  # we use $CI_JOB_TOKEN here which is a special token provided by GitLab
  - echo -n $CI_JOB_TOKEN | docker login -u gitlab-ci-token --password-stdin $CI_REGISTRY

Build docker image:
  before_script:
    - *docker-script-before
  stage: build
  tags:
    - k8s-runner
  except:
    - tags
  script:
    # fetches the latest image (not failing if image is not found)
    - docker pull $CI_REGISTRY_IMAGE:latest || true
    # builds the project, passing proxy variables, and vcs vars for LABEL
    # notice the cache-from, which is going to use the image we just pulled locally
    # the built image is tagged locally with the commit SHA, and then pushed to
    # the GitLab registry
