# To build the image, start with the following command:

# $ docker build -f Dockerfile -t demo/oracle-java:8 .
# -f specifies the Dockerfile. This can be skipped if the filename used at the beginning of this process is Dockerfile.

# -t specifies the name of the image. The name demo/oracle-java, and the 8 after the colon, specify the image tag. The tag 8 is used because we are using Java 8. This can be changed to any tag name that makes sense.


# docker build -f Dockerfile -t helloworld .
