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
haveged
ライブラリをインストールする ここ助言がありますか?
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!
