create 3 instances
jenkins 
ansible
webapp

connection : jenkins -- > ansible & webapp
		 ansible -- > webapp

setup jenkins
free stype and repo give proj: one
manage jenkins -- > plugins -- > public overssh

manage jenkins -- > configuratiuon settings -- >
SSH SERVERS -- > Add -- > 

name & hostname & user & remote dir -- > advance -- > password -- > test config 
now you will get sucess
do it for all the nodes ansible & webapp

check by doing firts build
Jnekins server and check on var lib jenkins workpace

build step -- > Send files or execute commands over SSH
SSH Server -- > Name: Jenkins -- > exec command: rsync -avh /var/lib/jenkins/workspace/one/* root@172.31.47.223:/opt 
save and apply
do build 2 and it will success 
goto ansible server and check opt


go for job oen and config and ssh server on build steo and exec command

cd /opt

docker image build -t $JOB_NAME:v1.$BUILD_ID .
docker image tag $JOB_NAME:v1.$BUILD_ID rahamshaik007/$JOB_NAME:v1.$BUILD_ID
docker image tag $JOB_NAME:v1.$BUILD_ID rahamshaik007/$JOB_NAME:latest
docker image push $JOB_NAME:v1.$BUILD_ID rahamshaik007/$JOB_NAME:v1.$BUILD_ID
docker image push rahamshaik007/$JOB_NAME:latest

docker image rmi $JOB_NAME:v1.$BUILD_ID rahamshaik007/$JOB_NAME:v1.$BUILD_ID rahamshaik007/$JOB_NAME:latest

advanvce on top and click Verbose output in console

if u build it will fail because the conatiner name is varied 

go to playbook and change container and give another name

- hosts: webapp
  tasks:
   - name: stop container
     shell: docker stop mydockercontainer
   - name: removig container
     shell: docker rm mydockercontainer
     shell: docker stop mydockercontainer
   - name: removing image
     shell: docker rm -f rahamshaik007/img1
   - name: create new container
     shell: docker container run -itd --name mydockercontainer -p 9000:80 rahamshaik007/img1

use webhook for this

SAME PROJECT FOR WEBAPPLICATION:

CREATE 3 INSTANCES (JENKINS, ANSIBLE, DOCKER)
CHANGE ALL HOSTNAMES 
INSTALL JAVA ON ALL OF THEM
sudo amazon-linux-extras install java-openjdk11 -y

systemctl status sshd


 

GO TO JENKINS SERVER

go to ansible node and loginto ansadmin and under /opt/docker you will see files
