Docker内の起動時にSpring-bootアプリケーションが起動しない

Dockerコンテナ内で単純なSpring-Bootアプリケーションを実行しています。起動時に、Java -jar MY_JAR.jarまたはmvn spring-boot:runのどちらで開始した場合でも、アプリケーションは常に次の時点でハングします。

2014-12-22 23:26:58.957  INFO 1 --- [ost-startStop-1] o.s.b.c.embedded.FilterRegistrationBean  : Mapping filter: 'hiddenHttpMethodFilter' to: [/*]

これが問題です。これは、コンテナー内で実行されている場合でも、DigitalOcean（1CPU、1GB MEM）のUbuntu14.04ボックスでのみ再現できます。私のローカルマシン（Mac）では、すべてが正常に実行されます。

Dockerfile：

FROM Java:8
ADD target/MY_SERVICE-1.0-SNAPSHOT.jar /data/svc.jar
EXPOSE 8080
CMD ["Java", "-jar", "/data/svc.jar"]

私が試したこと

  • JVMにより多くのメモリを提供します（マシン全体の75％）
  • 提案どおりにhavegedライブラリをインストールする ここ
  • 他のすべてのバージョンのJava私は手に入れることができました

助言がありますか？

助けてくれてありがとう。

とった！ホストにhavegedをインストールすると、プロセスはすぐに進み、Springは正常に起動しました。 dockerがホスト上のhavegedとどのように相互作用するかについてもう少し調査したら、さらに投稿します。

要約すると、ホストで発行された次のコマンドで問題が修正されます。

apt-get install haveged -y

誰かがこれを詳細に理解しているなら、気軽に投稿してください！

現時点で私が理解していないのは、ホストマシンに追加のコードが必要であり、すべてがDockerコンテナー内で分離されていない理由です。

後でここに来るかもしれない人のために。最も簡単な解決策は、Dockerfileを変更し、次のようにエントリポイントを設定することだと思います。

ENTRYPOINT ["Java", **"-Djava.security.egd=file:/dev/./urandom"**,"-jar","app.jar"]

30秒から15分の間（またはそれ以上かもしれませんが、殺された）のどこかにアプリがぶら下がっている経験があります。

詳細を共有する他の投稿から：

これがないと、Javaは/dev/randomを使用してSecureRandomクラスをシードし、Javaコードが予期せずブロックされる可能性があります。

または、$Java_HOME/jre/lib/security/Java.security構成ファイルに次の行を追加します

securerandom.source=file:/dev/./urandom

脚注：上記の例では、Javaをだましてファイル名を受け入れるようにするには、余分な/./などの奇妙なファイル名が必要です。/dev/urandomを使用するだけの場合、Javaは、あなたが本当にそれを意味していないと判断し、あなたが書いたものを/ dev/randomに置き換えます。狂気！
