-# Dockerize Spring Boot REST API Application
-
-## Step-1: Pre-requsites - Create Simple SpringBoot HelloWorld REST API
-- Create a simple Helloworld rest api
-- In our case, we will downloas this from our course artifacts during project setup. 
-- Run locally and test
-    - Access Helloworld REST API
-    - http://localhost:8080/hello
-    - http://localhost:8080/hello-bean
-```json
-{
-  "message": "Hello World Bean",
-  "appversion": "V1"
-}
-```
-
-## Step-2: Create Dockerfile
-- Create Dockerfile on Application root folder
-
-```
-FROM openjdk:8-jdk-alpine
-VOLUME /tmp
-EXPOSE 8080
-ADD target/*.jar app.jar
-ENV JAVA_OPTS=""
-ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]
-```

-## Step-3: Update pom.xml with spotify plugin
-- Update the pom.xml with Spotify plugin
-- For additional reference, please refer below link
-- **Important Note: ** 
-    - In the below pom.xml, please ensure we replace "stacksimplify" in repository tag with your docker hub id. 
-    - <repository>stacksimplify/${project.name}</repository>
-- https://github.com/spotify/dockerfile-maven
-- https://mvnrepository.com/artifact/com.spotify/dockerfile-maven-plugin

-## Step-4: Package as Docker image and Run locally on Docker Desktop.
-- Run the below command from application root folder or run the same from Spring Tool Suite IDE
-```
-mvn clean package  
-```
-- Execute docker commands 
-    - List docker images 
-    - Run the docker image locally
-```
-docker images
-docker run -p 80:8080 stacksimplify/springboot-helloworld-rest-api:1.0.0-RELEASE
-```
-- Access Helloworld REST API
-    - http://localhost/hello
-    - http://localhost/hello-bean
-```json
-{
-  "message": "Hello World Bean",
-  "appversion": "V1"
-}
-```
-
-## Step-5: Push Docker Image to Docker Hub
-- Pre-requisites
-    - Create an account on docker hub 
-    - https://hub.docker.com/
-- Login to docker hub
-- Push the newly created image to docker hub.     
-```
-docker login
-docker push stacksimplify/springboot-helloworld-rest-api:1.0.0-RELEASE
-docker push **YOUR DOCKERHUB REPO NAME**/springboot-helloworld-rest-api:1.0.0-RELEASE
-```
-- Verify the new repository with **1.0.0-RELEASE** tag should be displayed on Docker Hub.
-
-## Step-6: Spring Boot - Docker Image Versioning
-- Update version tag in pom.xml
-```xml
-	<version>2.0.0-RELEASE</version>
-```
-- Package the new image
-```
-mvn clean package
-```
-- Run the docker image locally (if required to test)
-```
-docker images
-docker run -p 80:8080 stacksimplify/springboot-helloworld-rest-api:2.0.0-RELEASE
-```
-- Push the docker image to Docker Hub
-```
-docker push stacksimplify/springboot-helloworld-rest-api:2.0.0-RELEASE
-```
-- Verify the same in Docker Hub. New release tag **2.0.0-RELEASE** should bedisplayed
-
-## Step-7: Run docker image in detached mode
-- Run docker image in detached mode (no console output of spring boot application)
-- So far we are running in foreground mode where we get the spring boot application console output. 
-```
-docker run -d -p 80:8080 stacksimplify/springboot-helloworld-rest-api:2.0.0-RELEASE
-docker ps
