Build locally:

docker run --rm -v `pwd`:/blog -w /blog yitsushi/hugo-extended-builder

GitLab Pipeline

build:
  stage: generate
  image: yitsushi/hugo-extended-builder
  script:
    - hugo
  artifacts:
    paths:
      - public/
      - Dockerfile
    expire_in: 1 day

Dockerfile marked as part of the artifact because that way, in a later step we can build our finale image that contains only the artifact as webroot without git, like:

docker:
  stage: build
  image: docker:stable
  before_script:
    - docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.gitlab.com
  script:
    - docker build --pull -t $CONTAINER_CURRENT_IMAGE .
    - docker push $CONTAINER_CURRENT_IMAGE
  only:
    - master
  variables:
    GIT_STRATEGY: none

The corresponding Dockerfile:

FROM nginx:alpine

LABEL maintainer="Balazs Nadasdi <yitsushi@protonmail.ch>"
