DockerSpringTomcatExample

in this project we are just creating Docker build by using already created war \ file. / /\ |--|

\ /\ / /\ ||

/ / / \ |\

#Step 1: build the image #build image will create war file , for running the war we need tomcat server. #docker build -t . #repository name must be in lower case

docker build -t docker-spring-tomcat .

#Step 2: check list of image

docker image ls -a

#Step 3: Running a container from the image #Syntax: docker run -itd --name -p : image-name:tag

note in the above syntax:

-d : represents (detached mode), note that if you don't run this in detached mode, the life of the container will be the life of the terminal in which you are executing it.

-p : represents the host-port to container-port mapping, if you substitute it with -P you will get a random port allocated by docker

--name : represents the name of the container

docker run -itd --name spring-container -p 5555:8080 docker-spring-tomcat:latest

Step 4: View all the containers

#Shows all the containers stopped and running docker ps -a

Step 5: Logging into the container

#Note: The container must be started before we can do this. docker exec -it /bin/bash

#Step 5: to check application on browser #http://localhost:5555/docker-spring-tomcat/ #5555 : exposed port over 8080

docker-spring-tomcat : spring project name
