Gitlab CI for Hugo

I have been playing around with a private Gitlab server. My goal was to automatically build and deploy my hugo site for my private web server. After looking around in the internet for similar solutions, I came up with the following solution for .gitlab-ci.yml

stages:
  - build
  - deploy

build:
  stage: build
  image: registry.gitlab.com/pages/hugo/hugo_extended:latest
  script:
  - hugo
  artifacts:
    paths:
    - public
  only:
  - master

# deploy with ftp following instructions from https://www.savjee.be/2019/04/gitlab-ci-deploy-to-ftp-with-lftp/
deploy:
  stage: deploy
  image: alpine
  before_script:
    - apk update
    - apk add lftp
  script:
    # Sync to FTP
    - lftp -c "set ftp:ssl-allow no; open ftp.ssl-login.nl; user $FTP_USERNAME $FTP_PASSWORD; mirror -X .* -X .*/ --reverse --verbose --delete public/ public_html/"

I use gitlab’s hugo_extended image because I use SASS for my stylesheet and this needs to be converted automatically. I then use an alpine image and add lftp to be able to upload the converted files to my web server.
