How to write Dockerfile
2.How to create Docker Image
3.How to Run Spring Boot in a Docker Container



4. How we can dockerize our springboot microservice ?
As a Developer,
• I want to dockerize my microservice….
• I need to write Docker File.
• Using Docker command, we need to create the Docker Image
• Docker Container is the running instance of Docker Image
• Entire Process is called Dockerize!!!
We can Dockerize any Java application.
OpenJDK8 is available in DockerHub
5. Create File with name “Dockerfile” and putting 4 fields
e. FROM- Use OpenJDK available in Docker
f. EXPOSE- 8080 port is available to outside the Container… (9090 is container Port)
g. ADD and ENTRY
h. Generate *.jar file by mvn install





What is Docker Hub ?
Ans:-
• It is kind of repository like GIT.
• GIT is storing source code. Docker image is storing in Dockerhub
• Docker File (i.e XX.jar)(Docker command)Docker Image (i.e XX.jar)
o Run the Docker Image on Docker Container
o Same Docker Image will PUSH to Docker Hub
o Pull the Docker image again from Docker Hub
•
• So,We need to create A/C (https://hub.docker.com/) in Docker Hub like Github
• How to push Docker Image to Docker Hub ?
• How to pull image from Docker Hub ?
We need specify some TAG before pushing Docker Image to Docker Hub.


Dockerize and Run :-
-----------------------
• docker image ls
• docker login (login id of https://hub.docker.com/ i.e djrabi007 for me!!!)
• docker build -t spring-boot-docker-rabi-file.jar .
• docker run -p 9091:8080 spring-boot-docker-rabi-file.jar
• http://192.168.99.100:9091/messageRabi



Add TAG and PUSH :-
-----------------------
a. docker image ls
c. docker tag spring-boot-docker-rabi-file.jar djrabi007/spring-boot-docker-rabi-file.jar
d. docker push djrabi007/spring-boot-docker-rabi-file.jar:latest


PULL and RUN :-
-------------------
a. docker pull djrabi007/spring-boot-docker-rabi-file.jar:latest
b. docker run -p 9091:8080 djrabi007/spring-boot-docker-rabi-file.jar
c. url:: http://192.168.99.100:9091/messageRabi
