h2oでMastodonを配信する方法を記述します。

environment(環境)

server: ubuntu16.04
Front web server is h2o,backend server are apache2.4 and masdon server(docker).
フロントはh2o。バックエンドはapache2.4とdockerのmastodonです

h2o ----   apache2 (domain1) port:81
    |
    ----   docker server(domain2 - mastodon) port:3000,4000

h2o config

very simple,but "//api/v1/streaming/" is little complex.why "/api/v1/streaming/" ? I think this is mastodon's problem but I solved.
とてもかんたんですね。"//api/v1/streaming/"のところがちょっときもいですけど、まぁ、なんとか。
