Prevent CNAME file in Jekyll from being deleted during the build process

If you have a custom domain, you may have to copy the CNAME file after every Jekyll build.

You can use the keep_files option in _config.yml to prevent the CNAME file in the _site directory from being deleted during the build process.

keep_files: ['CNAME']

If you are using Travis CI, you can copy the CNAME file to the _site directory after the build process. Here’s a sample .travis.yml configuration that you can use:

language: ruby
cache: bundler
branches:
  only:
  - dev
script:
  - JEKYLL_ENV=production bundle exec jekyll build --destination _site
  - cp CNAME ./_site/CNAME
deploy:
  provider: pages
  local-dir: ./_site
  target-branch: master
  email: [email protected]
  name: Deployment Bot
  skip-cleanup: true
  github-token: $GITHUB_TOKEN
  keep-history: true
  on:
    branch: dev
