Dockerization

Docker: - Docker is a platform designed to help developer build ,share and run modern application .

Docker file :- It is a text document , that contain all the commands a user could call on the comand line to assemble an image.

Dockerization : - The process of packing , deploying and running application using Docker containers

Step 1: - Create a REST api in spring boot application and perform the CRUD operation

GitHub code source :- github.com/SourabhAswal/springboot-docker.git

Step 2: - Create a docker file in the project folder

FROM openjdk:17-oracle
EXPOSE 8080
COPY target/springboot-docker.jar springboot-docker.jar
ENTRYPOINT ["java","-jar" ,"springboot-docker.jar"]

Step 3: Create a docker image from the docker file , which we created earlier

Before that you have to build a project so that it will create .jar file by using :

mvn clean install

docker build . -t springboot-docker:latest

Step 4 : Now we have to run that docker image

docker run -p 8080 springboot-docker

Step 5: Checking that REST api in postman tool ( Dockerization of Springboot- application completed )
