2. Build and execution (on a development environment)

  1. Know the script run:

    $ ./run
You need to pass some arguments! Examples:
./run docker rmi         # <- remove the generated docker image (docker-java-fibonacci-demo)
./run docker build       # <- build a docker image named 'docker-java-fibonacci-demo'
./run docker run         # <- run a docker container from image 'docker-java-fibonacci-demo'

  2. Build the jar

    $ mvn package

  3. Run the application:

    1. Through java:

      $ java -jar target/docker-java-fibonacci-demo-0.0.1-SNAPSHOT.jar 10

    2. Through maven:

      $ mvn compile exec:java -Dexec.mainClass="com.paulojeronimo.Fibonacci" -Dexec.args="10"

  4. Build the Docker image:

    $ ./run docker build
    Note
    		 this command with call mvn package automactically.

  5. Run the application (through Docker):

    $ ./run docker run 10

  6. Do clean up actions:

    1. Remove the Docker image:

      $ ./run docker rmi

    2. Remove the generated files in the project:

      $ mvn clean

3. Build and execution (using Docker only)

  1. Build the Docker image:

    $ ./run docker build Dockerfile.maven

  2. Run the application (through Docker).
