0. mkdir java-application
1. create a docker file named javaapp_mysql in directory java-application, for example

FROM java:8 WORKDIR / ADD DockerConnectMySQL.java / ADD mysql-connector-java-5.1.47-bin.jar / #extend environment classpath so that mysql connector may be used. ENV CLASSPATH=".:/mysql-connector-java-5.1.47-bin.jar:${CLASSPATH}" RUN javac DockerConnectMySQL.java EXPOSE 8080 CMD java DockerConnectMySQL

2. docker build -f javaapp_mysql -t java_mysql . -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.

NOTE: Do not forget the .(dot) at the end of command;

3. docker run java_mysql
