What are the steps to run a jar package in Docker?

The steps to run a jar file are as follows:

1. Create a Dockerfile and specify the base image and the jar file needed to run in it.
2. Use the ADD command in the Dockerfile to add the JAR file to the image.
3. Execute the command to start a jar file using the RUN command, such as java -jar yourapp.jar.
4. Build image: Use the `docker build` command in the terminal to construct an image, for example: `docker build -t yourimage .`
5. Run the image: Start the image using the ‘docker run’ command, such as ‘docker run -d yourimage’.
