2016/02/24 10:30追記 : IBM Container for Bluemixの情報を追記しました
ども、大瀧です。 本日公開されたIBM製Swift WebフレームワークKituraを、AWSでしかもDockerで動作させてみたのでご紹介します。
KituraはLinuxで動く
Bluemixのページでは当然KituraをIBM Bluemixで動作させる様子が全面に紹介されていますが、Swift自体はLinuxで動作することが知られているのでAmazon EC2やDockerで動作させることも出来るのでは？と思い立った次第です。
GitHubの手順に従うよう、Dockerfileを作成しました。
Dockerfile

CMD ./Kitura/.build/debug/KituraSample動作確認
- AMI : ubuntu-wily-15.10-amd64-server-20160217.1 (ami-552a2b3b) (東京リージョン)
- Docker : バージョン 1.10.2, build c3959b1
上記Dockerfileを保存し、Dockerイメージの作成、実行するだけです。サンプルアプリケーションKituraSampleは8090ポートをListenするのでポートをアサインし、curlでアクセスしています。
$ sudo docker build -t takipone/kitura .
: (略)
$ sudo docker run -d -p 8090:8090 takipone/kitura
$ curl localhost:8090
You're running Kitura
$動きました！
IBM公式Dockerイメージもあるよ(でも動かない)
BluemixにはIBM Container for BluemixというDocker対応サービスがあるので、Docker Hubにそれらしいイメージを見つけることができました。
- Docker Hub (ibmcom/kitura-ubuntuイメージ)
- IBM-Swift/kitura-ubuntu-docker (Dockerfileのソース)
ただ、手元でpullして試してみた限りではエラーで動きませんでした。Bluemix専用の構成があるのかもしれません。
$ docker ps -a

$まとめ
IBMが作った！Bluemixで動く！というので話題になっていますが、シンプルなSwiftのAPサーバーと捉えると、Dockerとの相性は実はとてもいいんじゃないか？と思った次第です。
これから育っていくフレームワークだと思いますが、Swiftの先進的な言語設計が様々な環境で活用できるのであれば、広く受け入れられる仕組みになるかもしれないですね！
