GitOps is an operational framework that takes DevOps best practices used for application development such as version control, collaboration, compliance, and CI/CD, and applies them to infrastructure automation.

It is a way of implementing Continuous Deployment for cloud-native applications. It focuses on a developer-centric experience when operating infrastructure, by using tools developers are already familiar with, including Git and Continuous Deployment tools.

The core idea of GitOps is having a Git repository that always contains declarative descriptions of the infrastructure currently desired in the production environment and an automated process to make the production environment match the described state in the repository. If you want to deploy a new application or update an existing one, you only need to update the repository - the automated process handles everything else. It’s like having cruise control for managing your applications in production.

GitOps = IaC + MRs + CI/CD

Infrastructure as Code(IaC): GitOps uses a Git repository as the single source of truth for infrastructure definitions. Git is an open-source version control system that tracks code management changes, and a Git repository is a .git folder in a project that tracks all changes made to files in a project over time. Infrastructure as code (IaC) is the practice of keeping all infrastructure configurations stored as code. The actual desired state may or maybe not be stored as code (e.g., number of replicas or pods).

Merge Requests (MRs): GitOps uses merge requests (MRs) as the change mechanism for all infrastructure updates. The MR is where teams can collaborate via reviews and comments and where formal approvals take place. A merge commits to your main (or trunk) branch and serves as an audit log.

Continuous Integration & Continuous Deployment(CI/CD): GitOps automates infrastructure updates using a Git workflow with continuous integration and continuous delivery (CI/CD). When new code is merged, the CI/CD pipeline enacts the change in the environment. Any configuration drift, such as manual changes or errors, is overwritten by GitOps automation so the environment converges on the desired state defined in Git. GitLab uses CI/CD pipelines to manage and implement GitOps automation, but other forms of automation, such as definitions operators, can be used as well.

[yogithakakarla]

Can we do the same gitops process using git for storing, Jenkins instead of code build and code pipeline please

[prashantsukhadeve]

Thank you Sandeep for valuable information. I always learn so many things from your video.

[mahender]

Nice, thank you for video, can you please do gitops video using opensource tools like ArgoCD, Devtron, Harness

[soufianeodf]

thanks for the good content, can you share please you presentation ? it's really awesome.

[miqbal]

Sandeep I need a course on Jenkins and Git where we can user terraform code for azure and deploy the infra on azure. Please suggest asap.

[Sammyi]

Really informative bro!
But can you recommend advance Terraform courses or make some on how to keep code optimized whenever we are working and more other scenarios

[VeereshPatel]

Bro please do latest (2021) crash course on
1.Angular 12
2- reactjs
3- nodejs-
4-- meanstack
5.mern stack
6-Real time project (product) development

Hello sir, I felt while going through the video that there is too much transition animation used and due to this I can't read what was written on the slides. I know you talk at a faster speed that's why you are changing slides at a similar speed. Just felt that slides could have simple transition, rest everything is great:)

Hi everyone
If We are running terraform code from Jenkins pipeline where terraform state file will store. Terraform code is saved in gitlab in my case

Please help me
