仮想化環境のDocker(Ubuntu)でNode.js&Hello Worldしてみた。
仮想化環境のコンテナを作るDockerが面白そうなので試してみた。
色々つまずいたところがあったが、別途書く事にする。
我が家の環境はUbuntuなので、オフィシャル環境のサンプル(docker-node-hello)をUbuntuベースに修正して動かしてみる。
Dockerfileは以下の通り。
# Node.js for ubuntu # # VERSION 0.1.0 # # ORIGINAL https://github.com/gasi/docker-node-hello # # AUTHER .h2o # # Use the Ubuntu base image provided by dotCloud FROM ubuntu:12.04 # Install Node.js and npm RUN apt-get update RUN apt-get install -y python-software-properties RUN add-apt-repository -y ppa:chris-lea/node.js RUN echo "deb http://archive.ubuntu.com/ubuntu precise universe" >> /etc/apt/sources.list RUN apt-get update RUN apt-get install -y nodejs # App ADD . /src # Install app dependencies RUN cd /src; npm install EXPOSE 8080 CMD ["node", "/src/index.js"]
Dockerfileとオリジナル環境のindex.js,package.jsonを同じフォルダに配置し、以下のコマンドを実行(node.js必須ファイルやnpmでパッケージのインストールが実施されるため５分ほど時間が掛かった...)

イメージ化も終わったので、それじゃあ動かしてみる。
ポートのマッッピング設定を行わないとコンテナ外からは通信できないので注意
（ここではコンテナ内の8080を実環境の8080にマッピングしてcurlでアクセスする）
$ sudo docker run -p 127.0.0.1:8080:8080 -d -i -t .h2o/node-hello /usr/bin/node src/index.js 029894558827 $ sudo docker logs 029894558827 Running on http://localhost:8080 $ sudo docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 029894558827 .h2o/node-hello:latest /usr/bin/node src/in About a minute ago Up About a minute 127.0.0.1:8080->8080/tcp navy_octopus
リアル環境からアクセスしてみると。
$ curl http://localhost:8080/ Hello World
Good Job!
