Step1 Launch 3 ubuntu instances Sg: All traffic name it as below 1. Jenkins_server 2. Staging_server 3. Prod_server Install jenkins setup on jenkins server
Step2 On Jenkins, staging and Prod server do below steps #sudo su #passwd root #Vijay22@ #vi /etc/ssh/sshd_config make here permit login uncommented and root login to yes #systemctl restart sshd
**Step3 **
Now, we have to connect our nodes i.e staging server and prod server to jenkins node
Manage jenkins > manage nodes and clouds > new node
Name - Staging_server
Remote root directory - /home/ubuntu/jenkins
Usage - use this node as much as possible
Launch method - launch agents via ssh
host -
credentials - add - jenkins - username and passwords - giver here uname as root and pw as Vijay22@
Host Key Verification Strategy - manually trusted key verification statergy
leave everything as default
##Do the above steps for prod server also
Step3 in github create repo name as main_devops_project ssh into jenkins server #sudo su #mkdir main_devops_project #cd main_devops_project
#git init #git add . #git commit -m "adding file into git" #git remote add origin #git push origin master (it will push the index.html file to github)
Step4 Now, create 1st freestyle job which will load code from git to staging_server only Name - Git_job Restrict where this project can be run - label expression = Staging_server Git repo - branch - master save the job
Step5 install docker and java onto Staging_server and Prod_server #apt install docker.io
Step6 Creation of docker file - so that it will copy index file from jenkins server to staging into docker container
ssh into jenkins server #sudo su #cd main_devops_project #vi Dockerfile push this dockerfile to git
Step7 Now, create build job which will only build your code Name - build-website (freestyle) Restrict where this project can be run - label expression = Staging_server build--execute shell -- #sudo docker rm -f $(sudo docker ps -a -q) #sudo docker build /home/ubuntu/jenkins/workspace/Git_job/ -t website #sudo docker run -it -p 82:80 -d website
Run Git_job first and then build-website job Now, check website is deployed on container or not <public_ip of staging_server>:82 Result: You will see your website is deployed on port 82
Step8 We have run 1 1 job manually Now , we have to integrate those job and create cicd pipeline Go to Git_job add post build action > build other projects project to build - build-website trigger only if the build is stable Save it
Step9 integrate jenkins with github with the help of webhook so that if you made any change in code , new job is triggered Test: made some changes in index.html , add file , commit it Result: you will see new job is triggered automatically
Step10 Now, we have to finally deploy our website to prod_server Create new job name as Prod_job (freestyle) Github project - Restrict where this project can be run - label expression = Prod_server scm: mention here also build-- execute shell #sudo docker rm -f $(sudo docker ps -a -q) #sudo docker build /home/ubuntu/jenkins/workspace/Prod_job/ -t website #sudo docker run -it -p 80:80 -d website (we are running it on port 80 coz we finally deployed it on prod server)
go to build-website job and add post build action --add here prod_job
on prod server run random container #sudo docker run -it -d ubuntu so that our pipeline works (coz we mention any privious container running should delete first)
imp: made some changes in index.html file on jenkins server commit it and push it to the origin Result: it will run all job automatically and your website is deployed on Prod_server
Check it on brower <public_ip of Prod_server>:80
