Spring Boot Application running inside Docker with mongodb and Java 11 - mongodb

Question

I am running a simple spring-boot application inside a docker container. Here is my specifications:
- Spring boot 2.1.3.RELEASE
- Java 11 with Windows 10
- Docker use : FROM debian:stretch-slim as packager - ENV JDK_VERSION="11.0.1"
Spring boot simple applications works fine with above configuration
When I added Mongodb (Spring data mongo) and started the spring boor applications, it works good in my windows machine, but when I run inside docker container it is throwing error as follows:

========================================================
I suspect, Spring Boot does npt support Java 11 completely or I am missing some Java module which I need to add to my Dockerfile.
As of now I have following java modules added to my dockerfile:
--add-modules \
java.base,java.sql,java.naming,java.desktop,java.management,java.security.jgss,java.instrument
Any suggestions will be helpful.

Answer 1

I changed the Docker image and its working fine now:
Here is the Dockerfile, useful if you want to setup Docker for Java 11 with maven.
