how to pack jar along with config file as docker image

AATHITH RAJENDRAN :

I have a jar file, pom file and config.yml file along with dockerfile inside a folder named app which is in /Desktop. How can I pack all those files into a docker image?

This is my current docker file. What should I change?

FROM java:8
WORKDIR /
ADD /Desktop/app $HOME/app
CMD ["java", "-jar", "appserver.jar", "server", "config.yml"]

Thanh Nguyen Van :

You could start with this simple Dockerfile:

FROM java:8
WORKDIR /
ADD app /app
CMD ["java", "-jar", "/app/appserver.jar", "server", "/app/config.yml"]

The Dockerfile should be created in a directory which contains also the app directory with your appserver.jar and config.yml files:

├── workdir/
│   ├── Dockerfile
│   └── app/
|       ├── application.jar
|       └── config.yml

Now, to build the docker image, run, in the workdir, the following command:

docker build -t app-name:1.0 .
