『なるほどUnixプロセス』付録DのSpyglassを起動する (Ruby2.6.3, bundler1.17.2)

Ruby Unix

『なるほどUnixプロセス』付録D の「Spyglass」は触って学べるWebサーバー。同書で解説されているUnixプログラミングのテクニックを盛り込んでいる。

せっかくなので試そうと以下のコマンドにて起動を試みたが、起動しない。

# application's root dir
$ spyglass

環境

結論

以下のコマンドで実行可能になる。

$ bundle install
$ bundle exec rake compile
$ bundle exec bin/spyglass

f:id:ohbarye:20190504165422p:plain

dockerで起動する

docker container上で起動することもできる

$ docker run -it -v $PWD:/app -w /app ruby bash
# bundle installの結果等を永続化しないやり方

で立ち上げたあとは同じく bundle install から行う。

ローカルマシンで http://localhost:4222 にアクセスすると動いていることが確認できる。
