Spring Boot Application running inside Docker with mongodb and Java 11

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.
