Day-18 | What is CICD ? | Introduction to CICD | How CICD works ? |

[@Cloudnp9458]

6:36. Unit testing is nothing but testing code for a block or specific functionality. 7:10. Static code analysis is to verify format, all indentation is right, syntax is right, make sure u didn't declare any unnecessary variables. Code quality/ vulnerability testing is done to check for vulnerability, that can be misused by hackers 8:51. Automation testing/functional testing /endtoend testing, in this you verify your application in end to end manner such that one functionality doesn't affect other functionality. Reports - reports for how many units test passed , what is code quality etc. Deployment stage- deploying your application on a platform so that your customer can access your application.

00:02 CI/CD is a process that automates application testing and delivery 04:28 Delivering your application involves several automated steps. 08:49 Unit testing, functional testing, reports, and deployment are essential steps in application development. 13:19 Jenkins is an orchestrator that automates and integrates various tools in a pipeline 17:34 Deploying applications to different environments for testing and production 00:03 Jenkins is a binary platform used to deploy and manage services. 25:39 Using GitHub Actions or GitLab pipelines for CI/CD can help save resources and increase efficiency. 00:00 CI/CD Solutions are scalable and have emerging alternatives like GitHub Actions, GitLab CI/CD.

1:42 CI/CD is two step , continuous integration and continuous deli. CI is process where you integrate set of tools or set of processes that you follow before delivering your application to your customer. CD is a process where you deploy or deliver your application on a specific platform. Application has to be tested, scanned for एप्लीकेsn vulnerabilities, finally you deploy your application. CI/CD is a pipeline where you automate these things - Unit testing, Static code analysis, Code quality/vulnerability testing, Automtion testing (end to end testing of application), Report, Deployment (so that client can access application)

"Modern Day CI CD" part was awesome! , Thanks Abhishek for sharing such a great knowledge on CI CD for beginners.

[@practicaldeen5333]

Best explanation and teaching style. I am locked in. Trying complete this series within the next two weeks. 3 sessions at least every day. Much appreciated.

[@AbhishekVeeramalla]

Great to hear!

[@Cloudnp9458]

Whenever you are writing an application, you break them into chunks as jira stores for each of the functionality and keep submitting them to git repository. Versions of functionality are pushed to vcs(git,bitby,gitlab). Jenkins keep watch on git repository commits. Jenkins will act as a tunnel/orchastrator. That facilitates/integrate all these tools, maven,sonar, alm/reporting, k8s docker. Jenkins can promote application to dev env, stage env or production env. You install Jenkins master on one host and then you keep connecting ec2 instances to it. Isn't scalable like k8s. Jenkins is legacy tool.

[@akshatabiradar2802]

The way you explain the things that's amazing, easily understanding and clear, please make videos on how to find open source devops projects and contribute to it, this would be very helpful to get real time experience as beginner

Hi bro, quality and valuable content as usual. Just for clarification of doubt, @24:11/33:24, you mentioned 20 to 30 master nodes and 3 to 4 worker nodes. Please can you confirm if that was what you meant to say and if yes, why more master nodes than worker nodes? Remain blessed

[@harrypotter-sg2hz]

you're doing good services for us thank you so much sir

[@pavanprasad3061]

what are worker nodes and master nodes?

[@vineetsingh904]

master node is the server (suppose ec2) where Jenkins itself, and worker node (they are also ec2 ) which contain the pipelines (15.14) example: suppose there are 3 github repos of different project (ecom app, social-media app, LMS app) you setup up 1 master node (ec2) in which install jenkins and 3 worker nodes where 1st worker node contain pipeline for ecom , 2nd worker node contain pipeline for social media and so on.

[@strend2833]

Hello Abhishek, I have a question regarding using Github action in place of Jenkins. Apart from scaling using Github action, Can we also use Gibhub Actions to perform unit testing, reporting, static code analysis etc..

[@practicaldeen5333]

Very good ?

[@subhasismandal4180]

The GitHub actions part was a bit confusing because like instead of Kubernetes you could have taken another project example, I got a bit of confusion when you told when a new code change will be pushed to GitHub it will spin some new k8s pods/docker containers, are Github actions doing that at the backend? are they using that or how it is happening? Does GitHub action use k8s at the backend??

[@aakashsonkusare69]

SO GitHub Actions uses Kubernetes to spin up VM? Cant we do this with Jenkins instead of Kube? Cant we define in Jenkins that we need specific resources only so that it doesn't get waste. If not then how exactly it is done in Kube as we are only triggering GitHUb action and then Kube is handling rest. Got confused towards the end.

[@g-jalil6961]

Hi Abhishek, thanks for the wonderful session. My question is can staging environment be test system or quality/ pre-production system ?

[@AbhishekVeeramalla]

Yes

[@laxmid6483]

A question so here automatic scaling is possible with kubernetes or kubernetes can do the work what Jenkins is doing?

[@udaybhaskar98]

Kubernetes can manage the deployment of applications built and tested by Jenkins, and handle scaling and self-healing.

[@AshishGupta-oj3qe]

Thank you Abhishek for the simple explanation but I'm a bit confused how to explain these things in interview? Could you please make an video for that?

[@varshikvallala9610]

abhishek at 19:30 i was not clear about the 3/5 master and working node and tier architecture and about the terms dev, staging, production.. could you plz clarify.

I really liked your video, nicely explained. Everything is clear but there is a bit confusion in the last 10 mins where you talked about kubernetes and github action.

[@ravithota239]

What is the correct order to watch the videos in theCI/CD playlist?

Abhishek please explain about master nodes, worker nodes and that related stuff as it was difficult to understand in the video.

[@arvindpsk]

Is there a way to run a Jenkins stage with a different userid than other stages?

[@SasthaSS-o3s]

20:00 Hello Abhishek I have doubts like there is the production environment. After we run tests in staging, is Jenkins capable of deploying applications directly to the customers (or) is it a kind of stage 2 or something?

[@sanjeetyadav-lm5ts]

god of devops

[@AbhishekVeeramalla]

[@HUNTER-kt5wh]

Sir, Please avoid the playlist repeated like Jenkin zero to Hero and CI/CD Playlist it will cause confusion about which one needs to follow tool & avoid more time spent

Keep going

[@shadowdad132]

at which stage I need to worry about IP address assignment and DNS record ?

[@laxmid6483]

Can someone explain me if Jenkins and GitHub actions are examples of CI/CD then why he explained the advantages of kubernetes over Jenkins? Is kubernetes also one of the examples of CI/CD?

[@udaybhaskar98]

kubernetes along with Jenkins makes it more flexible so he explained it, kubernetes is not CI/CD tool

[@styr34]

He explained the CI/CD concept applied in Kubernetes as example, It's not a CI/CD tool, but it uses GItHub actions, which is a CI/CD tool for modern day problems.
