容器化的弹簧引导应用程序与oracle数据库重置连接
我有一个使用Oracle数据库的容器化的弹簧启动应用程序的问题。 我成功地构build了我的图像，但是当我使用docker运行它时，应用程序在获取连接池时受阻。 应用程序运行的连接重置exception，如果我尝试连接它，我得到另一个连接重置exception，但如果我刷新页面应用程序正常工作，直到我尝试稍后再次使用该应用程序。
Dockerfileconfiguration如下：
FROM openjdk:8-jre-alpine VOLUME /tmp ADD *.jar /app.jar EXPOSE 8082 ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","app.jar"] 应用程序属性也很标准：
server.port = 8082 spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver spring.datasource.url=jdbc:oracle:thin:@<ip>:1521:<database> spring.datasource.username=<username> spring.datasource.password=<password> spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect
我正在构build映像并使用以下命令运行docker容器：
docker build -t <image_name> . docker run -p 8082:8082 -d <image_name>`
我已经尝试了几件事情：
- 使用谷歌search的问题，我发现在Linux内运行时Oracle有熵问题，所以我添加了-Djava.security.egd = file：/ dev /./ urandom
- 这不起作用，所以我尝试了熵的工具。 我不知道到底在哪里安装它，所以我试图在两个地方安装它（在容器内使用
RUN apk -U add haveged在主机上（这是一个Ubuntu的xenial 16.04.4）） - 这没有任何工作，所以我试图通过从容器中删除
/dev/random来“破解”，并用符号链接replace它，使用ln -s /dev/urandom /dev/random，但即使这样也不起作用，所以我尝试更改java.security属性securerandom.source=file:/dev/random
没有选项从上面的工作，所以我尝试使用HikariCP连接池，但我有同样的例外。

好吧，我尝试过的东西没有任何工作，所以我尝试了以下内容：我将Ubuntu发行版更改为CoreOS（专门为容器使用），现在它工作的很好。 唯一的问题是CoreOS与Docker背后有几个版本，所以我限制了我可以使用的东西。
