Spring Shell appilication inside docker

I am trying to deploy/run a spring shell application inside a docker container. It is starting but filing when tries to open CLI.

2018-07-20 19:24:44.588  INFO 1 --- [           main] ConditionEvaluationReportLoggingListener :

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

This might be because it is not able to fine any terminal inside docker. How can we overcome this ?

docker file

FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD simulator-0.0.1-SNAPSHOT.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
EXPOSE 5432
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -Dspring.profiles.active=uat -jar /app.jar" ]

I run the container with the -t option to skip the error. And if you want to interact with the container, use -it.

Compile the image

$ docker build -f Dockerfile -t my-spring-shell-image .

See the image registry

$ docker images

Run the image !!

$ docker run -t -p 5432:5432 my-spring-shell-image

If you want access to the terminal you must type

$ docker run -it -p 5432:5432 my-spring-shell-image
