Hello from Docker!
This message shows that your installation appears to be working correctly.
 
To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
  (amd64)
 3. The Docker daemon creates a new container from that image which runs the
  executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
  to your terminal.
 
To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

# VOLUME specifies the temporary file directory as /tmp.
# The effect is to create a temporary file in the host's /var/lib/docker directory and link it to the container's /tmp
VOLUME /tmp
# Add the jar package to the container and rename it to app.jar. You can use relative paths or absolute paths. Here, the relative path is ADD springboot-es6.jar /springboot-es6.jar
# Run the jar package RUN bash -c 'touch /springboot-es6.jar'
