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! :)

[@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!

[@NR-bt7yz]

Awesome job Nana - thanks!

[@TechWorldwithNana]

Thanks for your support, much appreciated!

[@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! :)

[@michaelmichael8406]

As always, clear and cogent information with no wasted time. Thank you.

[@saikiran351]

You have a gift for making complicated stuff seem easy! Your teaching is smooth, clear, and packed with technical expertise.

[@ericfisher9385]

Presenting and explaining complex concepts in a simplified and easily understandable manner is your superpower! Thank you!

[@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.

[@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)

[@vipinmittal2415]

Wow Nana. I am falling in love with these videos. why I found these videos so late. Thank you so much for these detailed concepts explanations. your videos are exactly what I needed at this point of time. Thank you. Please don't stop.

[@aaen9417]

These videos are great Nana. Thank you so much

[@stuffedcode]

Great explanation on what GitOps is! Loved the CD integration part explanation, it's spot on!

[@TechWorldwithNana]

Appreciate your great feedback, thank you! :)

[@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!

[@NARASIMHAM1002]

Thank you Nana for clear and crisp explanation. It clearly shows your passion for tech!

[@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.

[@ikelewis678]

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

[@ИванЖалдак-ю8у]

Now this is how you make an educational video! Great job!

[@cesarolavo]

I came across one of your videos this morning completely by chance (well, not exactly by chance, ain't it, google?) and now I'm hooked on your channel. Kudos, Nana! All videos clear and precise. This will save me a few bucks. Sorry, Udemy! ;-)

[@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.

[@marabgc20]

I just discovered your channel and it's really really helping me begin to understand all this concepts and technologies! Thank you so so much, your videos are wonderful

[@travelvidme4796]

Loved the video. Simple... Powerful and very visual. I watch every day to gain small amount of wonderful knowledge

[@chuongtran6224]

Thanks Nana for the great GitOps introduction!

[@GermanLarez]

Sounds great when you put it that way, perhaps organizations should emphasize more in this, always thanks for sharing!

[@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!!

[@iamjimgroth]

Very clear and understandable explanation of GitOps. Thank you.

Congratulations from Brazil for the didactics and for the english

[@sebastiaanstoffels7565]

Great video Nana!

[@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

[@soumyamisra4936]

Thank you for the explanation. As you mentioned testing the config files and IAC code. Do you have any videos on how to test our IAC code and config files?

[@dsinghr]

Nana explanation is amazing

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

[@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.

[@JonathanLoscalzo]

Something that I think is a kind of interview questions. Rollback are ok, but... What does it happen with "migrations", or something that you might need to "rollback", these scenarios are not trivial I think... Great Content and useful!!! I would like to start your intro to kubernetes, Perhaps... following week.

[@geanfrancovolpe]

How do we ensure right configuration related to application is also going to multiple clients and multiple environments?

[@vasudevadernierstuff]

i was just learning devops but this also makes me interesting.

[@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?

[@gmitto75]

Love all your courses. Wish there was a course on Apache Spark from you.

[@rbelatamas]

Thank you so much! Brilliant video!

[@sereose]

Thank you for the video. Very informative.

[@sreerang3]

What's the benefits of pull rather than push ?

[@awsomeslayer1]

Can you show a live example of how Gitops would work when multiple people are updating it? I would really like to see a real-project like situation where Gitops is helping in project development.

[@laffinkippah]

It's actually explained in the video, maybe you missed it. Different people submit different changes as PRs that need to be reviewed and approved by other members of the team. Once the PRs are approved, they are merged into the main branch (sequentially, in the same order they get approved). Each time the main branch changes, those changes are pulled to (or pulled from) the actual infrastructure.

[@jazzochannel]

@@laffinkippah explaining a concept and showing a practical example is not the same thing. maybe you missed that?

[@santosharakere]

Excellent video, thanks👍

[@ithereos9554]

Re: Push vs. Pull, which one is considered better and why?

[@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???

[@jayrizzo1454]

Topic: Best ways to help identity differences in environments. Dev, QA, Staging, Production. There are so many ways, what are the best practices for maintaining environments for code hotfixes, db structures changes etc. That might be different between environments/servers. Or best ways to validate there are no differences. Broad topic. But curious.

[@joshvanathan1000]

@nana thanks for the video.. recently we came across a scenario like one of my team member has accidentally applied kubectl apply from their local machine. Which collapses the previous ingress controller, also during reverting they deleted the ingress namespace itself.. because of this, there is no way to do a helm rollback as well.. in this case, what would be the advantage of gitops to revert back the ingress to the previous state ?

[@KamilMansoor]

outstanding explanation
