run microservice ejemplo dockerizing digitalocean compose app and java spring docker spring-boot digital-ocean

java - microservice - La aplicación Spring-boot no arranca al iniciarse dentro de la ventana acoplable



spring boot docker compose (2)

Estoy ejecutando una aplicación de arranque de primavera simple dentro de un contenedor docker. En el inicio, ya sea que java -jar MY_JAR.jar con java -jar MY_JAR.jar o mvn spring-boot:run la aplicación siempre se bloqueará en el siguiente punto:

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

Aquí está el problema, SOLO puedo reproducir esto en una caja de Ubuntu 14.04 en DigitalOcean (1CPU, 1GB MEM), aunque se esté ejecutando dentro de un contenedor. En mi máquina local (mac) todo funciona bien.

El Dockerfile:

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

Cosas que he probado

  • Dale más memoria a JVM (75% del total de la máquina)
  • Instalar la biblioteca haveged como se sugiere here
  • Cualquier otra versión de Java que pudiera tener en mis manos

¿Alguna sugerencia?

Gracias por cualquier ayuda.

¡Lo tengo! Una vez que instalé haveged en el host, el proceso avanzó de inmediato y el resorte arrancó bien. Publicaré más una vez que haga un poco más de investigación sobre cómo la haveged acoplable interactúa con haveged en el host.

En resumen, el siguiente comando emitido en el host solucionará el problema:

apt-get install haveged -y

Si alguien tiene una comprensión detallada de esto, ¡siéntase libre de publicar!

Lo que no entiendo en este momento, es por qué la máquina host necesitaba un código adicional, y todo no estaba aislado dentro del contenedor de la ventana acoplable.

Para aquellos que puedan venir aquí más tarde. Creo que la solución más sencilla es modificar Dockerfile y tener el punto de entrada de la siguiente manera:

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

Tenía experiencia con aplicaciones colgadas en cualquier lugar entre 30 segundos y 15 minutos (o tal vez más, pero me mataron).

Desde el otro post que comparte detalles:

Sin esto, Java usa /dev/random para SecureRandom su clase SecureRandom , lo que puede hacer que el código Java se bloquee inesperadamente.

Alternativamente, en el archivo de configuración $JAVA_HOME/jre/lib/security/java.security , agregue la línea

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

Nota al pie: En los ejemplos anteriores, necesita el nombre de archivo de aspecto loco, por ejemplo, extra /./ para engañar a Java para que acepte su nombre de archivo. Si solo usas / dev / urandom, Java decide que realmente no lo decía en serio y reemplaza lo que escribiste con / dev / random. ¡Locura!
