Docker How To Run Java Jar
Running a Java jar file inside a Docker container is easier than you might think. We are going to show you how you can define an image and run a container based on that image using a jar file as the main application or command.
We’re actually kind of cheating by using a base image that already has Java installed.
You can define an image using a Dockerfile like this:
FROM anapsix/alpine-java COPY test1.jar /data/test1.jar CMD ["java","-jar","/data/test1.jar"]
Build it like this:
docker build -t my-image1 .
Run it like this:
docker run -d my-image1
