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.

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)

THIS GUY IS A LEGEND!! Best explanation and teaching. More people need to hit the like button. Thanks for sharing all this knowledge.

[@AbhishekVeeramalla]

I appreciate that!

[@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.

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

Hi Abhishek, I learn CICD using tools such as maven, SonarQube, nexus, tomcat and Jenkins. I didn't see you use some of these tools of these tools. I saw you use maven, docker and GitHub actions and AWS tools. Now my question is what tools did you use in place of SonarQube, nexus and tomcat. Because i didn't see you use any of these tools.

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..

Very good ?

[@faisaliqbal7382]

That is a very nice explanation.

[@AbhishekVeeramalla]

[@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.

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??

[@titiandmum]

Thank you so much

[@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.

Thank you Abhishek for the great video and for your hard work! I have a question. What if we install Jenkins master in the k8s cluster and run Jenkins agent in the same Kubernetes cluster? Every time when there is a job, Jenkins will create a pod with Jenkins agent and will delete it after? Is that a good solution for real-world situation?

yes, it is a good solution.
