erorrrr Purpose

The application is to present different ways to generate docker image from springboot microservice or any java application

Ways of generating docker image

using spotify plugin
using google's Jib pluging

Using spotify plugin

to build docker image locally
```
mvn clean install
```
to build docker image and push to docker repository
```
mvn clean install dockerfile:push
```

Using jib plugin

The docker image built by Jib plugin is smaller than spotify plugin as Jib plugin uses gcr.io/distroless/java image by default, which is quite smaller in size. We can also change the default image using configuration

to build docker image locally

 mvn clean install jib:dockerBuild

to build docker image and push to docker repository

mvn clean install jib:build

To run docker application on local

using spotify plugin

docker run -p 8080:8080 ankitpec72/docker-demo-service-spotify:1.0-SNAPSHOT

using jib plugin

docker run -p 8080:8080 ankitpec72/docker-demo-service-jib:1.0-SNAPSHOT
