    MarkdownをPDFに変換する

docker build -t md2pdf .
cat /path/to/input.md | docker run --rm -i md2pdf > /path/to/output.pdf

オプションはwkhtmltopdfのマニュアルを参照。
EXAMPLES

スタイルシートを適用する

--user-style-sheetを指定する。
cat /path/to/input.md | docker run --rm -i -v `pwd`:/mnt md2pdf \
--user-style-sheet /mnt/user.css \
> /path/to/output.pdf

--print-media-typeでprintメディアタイプを有効にして改ページ（page-break-before/afterを定義）する。
cat /path/to/input.md | docker run --rm -i -v `pwd`:/mnt md2pdf \
--user-style-sheet /mnt/user.css \
--print-media-type \
> /path/to/output.pdf

ページ番号を振る

ページ番号を付与する場合は次のようなheader.htmlを用意してこれを--header-htmlに指定する。
渡されるパラメータはマニュアルの"Footers And Headers"を参照。
<html>
<head>
  <meta charset="UTF-8">
  <script>
    function subst() {
      var vars={};
      var x=window.location.search.substring(1).split('&');
      for (var i in x) {var z=x[i].split('=',2);vars[z[0]] = unescape(z[1]);}
      var x=['topage','page'];
      for (var i in x) {
        var y = document.getElementsByClassName(x[i]);
        for (var j=0; j<y.length; ++j) y[j].textContent = vars[x[i]];
      }
    }
  </script>
</head>
<body style="border:0; margin: 0;" onload="subst()">
  <table style="border-bottom: 1px solid black; width: 100%">
    <tr>
      <td style="text-align:right">
        Page <span class="page"></span> of <span class="topage"></span>
      </td>
    </tr>
  </table>
</body>
</html>
cat /path/to/input.md | docker run --rm -i -v `pwd`:/mnt md2pdf \
--user-style-sheet /mnt/user.css \
--print-media-type \
--header-html /mnt/header.html \
> /path/to/output.pdf
