Spring Boot Devtools auto restart error

I'm following this guide https://medium.com/@lhartikk/development-environment-in-spring-boot-with-docker-734ad6c50b34 to try and get auto restart, live reload and remote debugging working with my simple spring boot application in a local docker container.

Dockerfile:

FROM openjdk
VOLUME /tmp
ADD target/learn-docker-0.0.1-SNAPSHOT.jar app.jar
RUN sh -c 'touch /app.jar'
ENTRYPOINT ["java","-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

Run command:

docker build -t learn_docker .
docker run -p 8080:8080 -d learn_docker
