How to Run a Jar in a Docker Container

Create the Dockerfile

# Start with a base image containing Java runtime
FROM java:8-jdk-alpine
COPY /spring-boot-0.0.1-SNAPSHOT.jar /opt/
WORKDIR /opt/
EXPOSE 9090
ENTRYPOINT [“java”, “-jar”, “spring-boot-0.0.1-SNAPSHOT.jar”]

• jar file spring-boot-0.0.1-SNAPSHOT.jar is in the same directory where Dockerfile is

docker build -t <give a name for docker container here > .

ex : docker build -t spring-boot .

docker run -p 9090:9090 <docker image name>

ex: docker run -p 9090:9090 spring-boot
