Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

何故Dockerを使うべきか

Why Should I Care (For Developers)

"Dockerが面白いのはシンプルな環境に隔離性と再現性をもたらしてくれることだ．ランタイムの環境を一度作れば、パッケージにして別のマシンでも再利用することできる．さらに，すべてはホスト内の隔離された環境で行われる（VMのように）．最も素晴らしい点は，シンプルかつ高速であることだ．"
