Simple DevOps Project-2 | CI/CD pipeline using GIT, Jenkins & Ansible 

Perfect, With your playlist I am feeling like I executed a DevOps project. Thanks a lot

No words to express your effort towards this 26 videos. After watching these 26 videos one can feel themselves as a DevOps engineer, thank you so much valaxy technologies and each and every trainer.

Hi Sir, Great video Appreciate your efforts. Last few months I was searching for CI/CD Deployment but haven't understood a concept When I went through all your CI/CD videos then I get an idea of how real-time work happen. Very satisfied. Thank You Again !!

Sir Excellent video I never seen before, very nice explanation. I'm requesting you that, please clear my below doubts. 1)In real time who will maintain ansible server. 2)is the job will built if mobaxterm get inactive. 3) please make a video on where the tests should be done in real time and what's the role of devops engineer after post build if test cases where failed and how to automate then.

Team your all videos are very really nice to understand easily to anyone and all are followed very systematically. I have one question here i.e as per the pipeline build generates in Jenkins home directory, but in this video I did not understand how .war file got automatically transferred on Ansible server. I think that part is missing here . Please help us to clear that part.

I am happy to share ..i made this setup on my own AWS by watching your vedios..Thanks shankar..for sharing your knowledge.

Thanks good explanation, Please setup one project using Developers-->git------>s3(AWS S3 source)-->code Pilpeline (AWS)-->CodeDeploy (AWS)--->Target server (AWS Instance) Please setup a sample maven project setup Thanks in Advance...! Waiting for your reply

Thanks so much and I really enjoy your lectures !! however you said it is located on /opt/playbooks/webapp/targets/webapp.war on ansible server to copy/deploy it to the tomcat server. we have not seen how this war file got to this location from jenkins. I know in the previous video this war file ended up in tomcat using jenkins deploy to container. I am quite confused.

I had a doubt, in my ansible server I am not able to find any playbooks folder under /opt or webapp folder, so how did you do that?

Hi sir you said it is located on /opt/playbooks/webapp/targets/webapp.war on ansible server to copy/deploy it to the tomcat server. we have not seen how this war file got to this location from jenkins. I know in the previous video this war file ended up in tomcat using jenkins deploy to container. I am quite confused

Excellent Video. I was confused watching lot of videos on how ci/cd pipeline works. Good job sir. I am having a clear idea now.

Great video, thanks. Question: I dont understand how you can transfer the war file from Jenkins server to Ainsible server just using the remote directory (destination) of //opt/playbooks......if they are both on separate servers then wouldnt you need to provide a URL? Same question for when you execute the yaml file from Jenkins server

Very simple and standard explanation. End to end process. Thank you so much

Hello Sir, I liked your video. In real time we have multiple environment and we need to deploy the code in different manner. So do we need multiple playbooks for each and every environment so that it accomplish the multiple task. Is there any other way so that we can write playbooks inside jenkins job rather than writing on to Ansible servers?

Liked the way video and real-time project is made. May i know why Ansible is more preferred over Jenkins for deployment ? Can you explain a more complex example in-order to know the edge of Ansible over Jenkins? Can you likewise help many of us with exceptions and questions while we making the project or general errors that we might face? Thanks.

bro at 29:15time, as you said if we added one more playbook in the same test, the build will execute the previous playbook and preset playbook? or it will execute only the new playbook only?

Hello Shankar, Thanks for sharing your knowledge. Your videos have been very helpful. Pls I have one doubt. If you want to use ansible to deploy over many servers say like 100, Are we to set the password less authentication manually on each servers or there is another faster way. Your response would be appreciated

Such a fabulous explanation Brother. Thanks for coming to RU-vid. God bless you. I m from Hyderabad KPHB, learned many many things from you.

Thanks a lot for creating this playlist. I was so lost and then your videos came up as a saviour.

One question... .war file exist in /var/lib/jenkins folder under webapp.. how you copied that under /opt folder??? Have you manually copied or it was created by any job???pls advice

Hello, I am following Valaxy Technologies Videos, Video's demonstration is very highly real-world scenario-based, Can you also make video over Using git-->Jenkins-->Ansible-->Elasticbeanstalk Instances or AWS ECS (Docker-containers).

Thank you so much . I watched the video recently and it was really helpful. Just a heads up to those who are going to watch this in future. PUBLISH OVER SSH plugin has been suspended by jenkins in JAN 2022. So we need to to do it with the help of "scppublisher" plugin . Hope this might help.

Thanks very much for the clear explanation. One thing I was not sure of is where do we get that webapp.war file from? from some jenkins location or was it created in tomcat server when you deployed it using jenkins then you pulled it from tomcat server?

One of the most excellent videos which is best for beginners

This is great. However i am getting an auth failure when configuring the publish over ssh with my ansible host credentials. please i need help to move past this step.

Perfect sir easy and simple configuration method.

I have done this and got success this project . thank you. ansbile part i got error but verified another your vidio to setup ansible on redhat and overall it got success

Thanks a lot for such a wonderful video..I have one doubt. u said that we can deploy any number of servers by copying the IP address of nodes, for suppose if i want to deploy on 10 servers in that if any of the servers fails, fr suppose 6th server fails.

Perfect after watching both the video ansible installation and this video no issue at all project running successfully thanks sir great job

Thank you so much for these videos..I have been learning the DevOps methods from your videos and you are an awesome tutor

is real time environment and process also same right!

Dear Mentor -- this is an awesome demonstration. this has helped me a lot to understand the continuous deployment using jenkins and ansible. I have liked and subbed because of this video. real quality stuff. Waiting for the next session which covers the deployment of docker container from jenkins. any planned date like when you are going to post that video.

Hi sir, you mentioned in source path webapp/target/*.war but war file copy from jenkins means it will be in workspace?

Hi my friend, thank you for your efforts, my question is how did you get/moved webapp.war to ansible server from the git repo while ansible server just created and configured in 14:15 ?! while jenkins&ansibile ssh authentication config was created in 23:40?

do we need separate vms for git,maven,jenkins, webserver and ansible?

everything is okay regarding clear explanation ..... i have a query that how to rollback to github or (developer) if the code is not correct ?? could you explain please??

In 29:10 , you said we can add another task on playbook to install tomcat server, how can i install it while the aws instance is not available or do i need to create the tomcat instance manually then install the tomcat package ?

Nice explanation. I am a bit confused and got an error in giving the source files path. Error: "SSH: Transferred 0 file(s)" Which path need to set in the source files? please reply.

Excellent video... where is the destination folder is present in tomcat server? /opt/apache-tomcat-8.5.32/webapps?? but u wrote as //opt//playbook in remote directory in post build actions.

U can use first project tomcat server or different? like host michine

Great video. However, I have a query. I am building a maven job. However, the job gets stuck in between and finally fails with the error: JVM terminated unexpectedly with exit code 137. For this I tried to change min and max memory configurations in Jenkins settings (-Xmx512M -XX:MaxPermSize=512M). Still, the build takes a lot of time and finally fails. Could you please help to resolve this memory issue(or may be other)?? Also, tuned garbage collection. Do I need to create new instance with enhanced memory configuration?? Appreciate your response

Valaxy Technologies, Shankar Sir...Thank you very much This project, appreciate your effort. It helped me a lot to understand DevOps.

Hello Shankar, I would like to have job triggered when a new commit available but not on regular intervals using poll ssm. Is there a way?

Hi, thanks that was great explanation, 1 question I have if we enable poll SCM, then if any changes will happen Jenkins will automatically start building the job according to Crontab but How to know which git repo triggered the jenkins job ? There will be multiple repos and whenever commits has happened these repo Jenkins job will trigger

sir there no pom.xml file in your github due to which i am unable to build using jenkins. Can u help as i found this playlist is very useful for devops .

Interesting video. One question Lets say I have to get artifacts from artifactory and then deploy onto tomcat, How we can do it?

Shankar sir.. please teach me. I am going through all of your lectures and finding you as the best mentor for myself. You are incredible.

Hi sir, i have one simple doubt how you moved warfile into ansible server, actually war file is in jenkins and tomcat server but in video you are showing in ansible server also src:/opt/playbooks/webapp/target/webapp.war, can you please clear my doubt.

Good explanation... one doubt "publish over ssh" plugin missing in jenkins. can you help .

Can we modify playbooks which are already created or we have to create new playbooks always?

hi i like ur videos a lot but i have got a question in this video what if there are multiple target machines and its really hectic to create users and add ssh key to all the target machines.

After copying war to Ansible, how does Ansible deploy it? do we need another Jenkins job for that?

Crystal clear explanation thank u so much .can u please tell how to use ansible for live deployment

sir can we use "scp" or "nscp" command for copeing that .war file from jenkins to ansibule instead of using ssh over plugin is it pasible by using shell

Your videos are simply amazing andi.. Thanks for the knowledge..

If you deploy Multiple .war files into /wabapp folder in tomcat server through JENKINS,which war file can tomacat server serves ?. It is one of the useul pipeline video i have seen.Thank you so much sir.

Hi Shankar, thanks for the wonderful video. Can you please make a similar devops video using chef as configuration mgmt tool? (I ask because AWS OpsWorks uses chef)

Hi sir, In last video means sample devops project 1 , you didn't use ansible for deplyoing . In this video you used ansible . My question what will be the advantage of using ansible in deploying . could you please explain this ? how it makes different

i am facing one issue on ansible playbook source and destination in playbook sir

Hello sir I am very much interested watching simple Devops-project,when you are going to upload remaining videos for complete of this simple Devops project..,plz share your inputs...

hello sir, Thanks for sharing your knowledge. Sir, I have one doubt? if we have an application with Database then how could we upload DB into the console? . in real-time also will we use a tomcat server for java projects?

Amazing knowledge and great teaching in simple words depicts the knowledge levels of the tutor.

Thanks a lot for such a wonderful video. Am looking for the next video but am not able to find it. Please upload it asap it would really help. Thanks a lot once again.

sankar..u r awesome presenter...pls do share devops engineer daily roles n also interview questions...which will help us a lot

Neat & clean explanation understood clearly entire process

Thanks for the video. During post-build action, copying war file from the source to destination did not get where did you get the source path i.e webappstarget/*.war.

Hi, I have scenario like jenkins and ansible server two different aws ec2 servers i have been trying to deploy an app by using jenkins pipeline. Please tell me how to integrate jenkins and ansible b/w two different sever. Please suggest how write jenkins pipeline job

Superb explanation !!! .... Thank you .....

Hi.... helpful video.... i have a question.... if we can execute cicd through the help of cron according to previous video then why we need ansible for the same?.......... your answer will be helpful for me

проект Very cool project, but I have a problem. Not created .war file on the ansible server. How can this be solved? It is impossible to integrate into the chain git+jenkins+ansible+tomcat Ansible itself. Without ansible works. C Ansible no.

Source file location u should have entered complete path i.e. , opt/playbook/webapp/target/*. war But u did half of work above and rest in remote directory?

one doudt how jenkins knows to place the war file in ansible server in /opt/playbooks/target/webapp.war,, we did not create any /opt/playbooks/target directories in ansible server any reply please

Tomcat & Ansible is installed on same machine or different I have confusion Please rename the serevers

Awesome tutorial series. Thanks for creating this. Could you please help me understand where and how we run Junit? Testing phase is missing it seems.

Thanks alot Sir . nice explanation. I have one doubt if i want to deploy the code into 10 servers same time , every server need to configure in jenkins server or any other procedure is there . pls help me

Very good explanation, Thank you

Sir can u explain how that war file is available in ansible server....under playbook/webaps/target location

Almost half of the comments are about how the .war file was copied into Ansible ....!!! Please explain about that step ?

Hello Sir, this is Rishikesh from Pune. Thanks to Shankar sir for your efforts in making things easier. I have succefuly completed your first project for CICD. But for this i got some difficulties while performing. These are 1) while performing the keyless authentication, i am not able to connect to the target machine 2) Bcz of that in configure section the test configuration is failing. 3) In this video you r operating the services with 'ansadmin'. But i have to use ec2-user. how can i make the relevant changes ?? I will be waiting for your rply.. Thank you again

Hi sir, whenever developers are committed code to GitHub Jenkins take that code and generate package. If I run the job 2nd time it will delete old package and it will create new package means it will override. If something goes wrong with new package how to rollback previous code? Plz help me.

You explained very well, Please post next video so that i can learn how to deploy using docker container. pls pls sir do it asap..I will be thankful to you.

My jenkins instance status check is failing, how should I proceed with it? Can you share the same videos for centos ?

Hai sir we are try to same way of pipeline syntax generator it's possible same way?

hello sir, how you created webapp.war file in ansible server(directory /opt/playbooks/webapp/target/) to deploy to tomcat server...? please share the steps to create webapp.war in ec2 instances

Hi Sir, here we have copied the war into webapps but where we can write step to stop tomcat first before deploying war file and start after war copied. Please reply I am confused here.

Nice Explanation. can u please explain how files are copying from Windows machine to Ansible server.

Hi Shankar, Very good videos and congratulations for your efforts. I am a cyber security professional and i'd like to know the security flaws that as a professional we need to be aware of and advice our IT colleagues while they are setting up the Devops in any organization. Thanks

Nothing but a great tutorial for learning jenkins. ;)

Hi sir, Actually i am looking to do deployments through ansible but the prblm is I have to deploy war files through jump server and deployed into remote server is it possible?

Wow Addicted this Tutorial. Really helpful.👍

really informative video. thankyou sir.i got one doubt.as war file forms in workspace directory how come path given in video in source files is webapp/target/*.war. could u explain it.

great job! it increased my confidence...Thank you for sharing your knowledge...

If you provide the previous video link , I hope it will be very help full.

Silent talent..Very interesting..

Excellent explanation bro.. God bless you.. 👍

doubt sir how did u get that webapp.war file in your ansible /opt/ file

how can we automate this ansible setup since you are doing all these manually generate ssh copy them to nodes and adding ansadmin to user,if we have 100s of server doing them manually wil take lot of time, so can we automate them.

Why we are adding user into visudo file it is must for giving root access for that user? and it is necessary for installing phython package into tomcat server?
