hi nana GitOps seems more like git pull request pls clarify me bit confused..,

[@elad3958]

I'm beginning to realize your youtube channel is the best spot on the web for all things Devops. When I learn something from you channels I will always share the URL. We are connected on linkedin. My name is Elliott Arnold. Just want to let you know how effective your Tubes are. Happy 4th of July (Im in America lol)

[@TechWorldwithNana]

@@elad3958 Wow thank you for this amazing feedback Elliott! Thanks especially for sharing and spreading the word 😊Happy Independence Day! :)

[@linamargothpinerosrubiano3684]

So good! Thank you very much Nana!! What I loved from this video is you make no assumptions, therefore elaborated the idea of GitOps in a very clear way for beginners and probably for advanced users who might lost any bits of info before… brilliant!!

[@aaronsteers]

Love this video! You did a great job explaining IAC. XaC was a new concept to me, but I may use this in the future. Also, I appreciated the clear way in which you described the natural evolution of IAC, why the local dev pattern is flawed, and how we solve that with git-managed pipelines.

[@bhagarenikhil]

I read many articles but did not find any article in which concepts are explained in a clear and crisp manner. You are awesome!

[@yashkumarbarot581]

This the only video one needs to watch to know what GitOps is all about. Great explanation Nana. Thanks.

[@TechWorldwithNana]

Thanks a lot Yashkumar, happy to hear that! :)

Outstanding way of presenting an overview with clear and concise info 🙏

[@gabrielarodriguez7320]

Thanks Nana!!, this is what I was looking for, you made it easy to understand! :)

[@opinoynated]

Thank you! GitOps is really valuable for AI research teams as well. Most of the time, blockers in development are caused by limitations in the infra and the turn around time before requirements are applied are usually long because of submitting ticket requests and discussions just so infra managers can do the changes.

[@arpanchakraborty9874]

Just clear and crisp. Bless you. Thanks so much

[@4eversuju]

wow! Thank you so much for this review Nana! Super helpful and I finally understand why some people choose to use jenkins versus argocd! Thank you so much!

Your videos are very clear and the animation is so sharp ! Thank you

[@manuelnucci_]

Very clear explanation! We'll have to change focus and start DevOps teams to develop their own CI/CD pipelines

[@ikelewis678]

Thanks for making the video that finally made the pull based GitOps concept click for me.

[@pritomdas6215]

So well explained, kudos to this kind of quality content!!!

[@lucasfe3436]

Nana, your contents are amazing! thank you very much!

[@brutusmaximumus]

A pattern we are using is to apply to a very low environment (e.g., dev or a devops dev env) from the PR itself. This allows teams to test the apply of their PR before merging to main and helps catch "apply time" errors. One challenge you have with this is that multiple PRs can overwrite each other's test apply maybe before the first one has been completely validated. To support this we put have a standing rule if there is an open PR < 2 hours old, hold off creating yours, or talk to the requestor first. If its over 2 hours, go for it unless you are nice then go talk to them first. Since we have composed our repos around teams there is rarely a conflict.

[@aaen9417]

These videos are great Nana. Thank you so much

[@trump1688]

Thank you for the great explanation! Easy to understand!

[@kolos121]

Great information! One thing I'd like to add is that in any urgent events (example the need to upgrade infrastructure due to high traffic) you would still want to leave open doors to do this quickly, like just doing terraform apply and skipping the whole commit and CI/CD workflow. Of course you should still commit this change but when seconds count you have to be prepared to break certain rules.

[@Ferregus]

Awesome video Nana, thank you a lot! I'm waiting for one about argocd.. Greetings from Brazil :)

Nice and clear explanation. Thank you.

[@DoodleIO.]

loving your videos👏👏 .. very informative and easy language ..please keep making videos for us 🙏🏻🙏🏻

[@zlonux]

Thanks Nana for the great video! Honestly, i don't know why 'gitops' appers as a separate direction, because as soon as you treat your infrastructure as a code, you have to apply all practices that you use for developers code i.e. vcs, build pipelines, tests, stages etc. - because it's a code. But, how to build your 'build' infrastructure as code (egg or chicken:))

[@ramkannan8955]

Alex Have you got the answer to your question. It seems she is not answered

[@jelledenburger992]

I agree, I find the line between IaC & GitOps to be very blurry. I think most IaC guys already adopt some kind of GitOps without realizing it.

[@GoglidesDev]

'gitops' appears as a separate direction -> Simply speaking, GitOps is IaC. I think it's going in a different direction (personal opinion, I could be wrong) is this practice is popular in container space (especially in orchestration tools like Kubernetes), where there is a concept of operators/controllers which keep looking for declarative config changes on git and making sure deployed state always reconcile with git state. It's the same thing in IaC, where IaC can have CI/CD pipeline doing the same job. Same principle, same workflow, but gaining popularity because k8s (or similar orchestration) becoming more mature.

[@polinakoornneef1145]

We were doing GitOps without realizing it. When I first heard about GitOps I thought that it is a new framework, but at it seems that the name is new.

[@nicolasafonso8916]

@@jelledenburger992 In my opinion, the most critical size of GitOps related to "storing IaC files and monitor evolution" is in the testing part. The way in which you verify the deployment (both by reviewing or which some sort of automation) makes the difference. (Just an opinion)

[@chuongtran6224]

Thanks Nana for the great GitOps introduction!

[@rajitpaul4676]

Thank you so much for this wonderful explanation!

[@abigailcharteris4329]

Thank you for this informative presentation, as a developer this seemed really obvious to me and it's what we did when we moved to cloud. The CI/CD pipeline is pretty much the same as app dev pipelines. What I'd like to see is the automated testing and validation of IaC - this is a well defined process with rich tooling in coding languages like Java, C# etc etc. but what are the best practises for IaC?

[@netUncle]

It's amazing lot more better than other videos I watched. Because very clear speech, nice easy and slowly pronouncing words. And lot more efforts put in visualization. This is the key and makes it amazing and best of the best. Keep up the good work. I have one question, how do we test IaC, can we write tests for it, or just create all infra in test account or something and then verify manually???

[@aL3891_]

great, concise summary as usual :)

[@saidireddy2246]

we are exactly using & following the same process, good to know follow this in detail and the global standards.

[@cesarolavo]

[@AnhNguyen-tf4yl]

I think another benefit the pull model has over the push model is it prevents the team from tampering with the deployment file like Jenkinsfile. For example, they can issue command in the file to print credentials to access the cluster. in other words, it separates CI from CD

[@sambasiva1702]

Excellent as always 👌 can you make some videos on flux and argo

[@feiyang9136]

very nice and useful video, my company flow is the same with your video. Pluse terraform enterprise, which has a queue for TF changes.

[@santosharakere]

Excellent video, thanks👍

[@davidef.982]

I already have an opinion but would be interested to know your opinion regarding pull vs push within gitops principle? What do you think about advantage and cons. Using one of those two options ? Again, yet another great video with clear and useful content 👍👍👍

[@aaronsteers]

Love this video but I wish you'd mentioned slash command. I've found, for practical purposes, triggering IAC pipelines via slash commands like /tf-apply is generally the preferred implementation.

[@josephbatish9476]

amazing video thanks !!!

[@WesleyRouw]

Hi Nana, thanks for the great video. One question: when for example our team changes something in our ansible playbook, what kind of automated tests can run whether to check this playbook is valid to go to the main branch?

[@robwells57]

Fantastically Explained! Thank You! - Can we extend GitOps concept to On-Premise as Infrastructure As Code Solution?

[@KamilMansoor]

outstanding explanation

[@michaelpacheco7421]

Amazing and clean explanation. Straight to the point! One question: why the need of a separate git repository? Why not the same production code repository?

[@1982iniceman]

Well one logic according to me is Benefit 1 : Access to infra code to only those team members , clear separation of concern between app code and infra

[@robertdy3402]

Nana, Your presentation about GitOps is excellent! Thank you! I learned a lot. I have 2 questions, i hope you do not mind: If GitOps = IaC + Version Control System + Merge Requests + CI/CD, don't you think that "Version Control system" is quite redundant because "Merge Requests" means you are already using a Version Control System. Another question is: Does GitOps require Git?

[@thomash.8297]

Perfect Nana!
