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)
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.
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.
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:))
'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.
@@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)
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.
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.
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!
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!!
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
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! ;-)
Hi Nana, Great job once again. You did it right, I am extremely satisfied with more information in less than 12 mins. You got a great teaching skills too :)
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.
Many thanks for the video Nana. A really very exciting feature for sys admins and net admins. Could you please consider a video that explains your ideas about SRE role? Ironically I found many professionals who don’t really know what an SRE is!!
I am new to the devops practices and these kind on videos are really great, simple, clear and easy to understand for me. It helps me to figure out instantly what is what and what direction to go. Thanks 🙏
Great stuff as always Nana! I would love to see Rancher/Longhorn/NeuVector type preso on GitOps-CI/CD. For us Rancher on EKS users with CodePipeline, etc. Exciting stuff - thanks again
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?
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?
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?
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???
Well explained and very clear, for me the difficulty are testes/unit tests for infrastructure for example with terraform it's not straight same thing with ansible and it takes time (we don't have access to world wide cloud like amazon or google) so for me I am using gitops I would say at 50% and trying to get it to 100% great video thank you
@@rb3694 Hi as I said in my previous comment we don't have access to aws GCP or Azure in my country so virtualization is still using on premise servers using vmware for most of them I mainly use terraform and ansible for IaC and for tests I tried to use ansible with molecule and goss there is also terratest but I don't master go language to be able to use it I am still learning
Hi Nana, what devops tool is available for automated testing IAC written in Ansible. I am currently using bitbucket for scm and ansible for deployment of playbooks. So currently I am same stage as mentioned by you in 4:08. We have Jenkins available to use for CI. But I am not sure which tool should be used for writing automated test cases for Ansible playbooks.
@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 ?
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.
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.

I read many articles but did not find any article in which concepts are explained in a clear and crisp manner. You are awesome!
This the only video one needs to watch to know what GitOps is all about. Great explanation Nana. Thanks.
Thanks a lot Yashkumar, happy to hear that! :)
You have a gift for making complicated stuff seem easy! Your teaching is smooth, clear, and packed with technical expertise.
As always, clear and cogent information with no wasted time. Thank you.
Agreed great channel
Thanks Michael, really happy to hear! 😊

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

Thanks for making the video that finally made the pull based GitOps concept click for me.
Hats off Nana for such precise and informative video of topic I was struggling to understand. Thanks and keep posting. Best wishes
Now this is how you make an educational video! Great job!
Outstanding way of presenting an overview with clear and concise info 🙏
Your videos are very clear and the animation is so sharp ! Thank you
Awesome video Nana, thank you a lot!
I'm waiting for one about argocd.. Greetings from Brazil :)
Nana, your contents are amazing! thank you very much!
Cristal clear explanation thank you Nana
Sounds great when you put it that way, perhaps organizations should emphasize more in this, always thanks for sharing!
Thanks Nana for the great GitOps introduction!
Very clear and understandable explanation of GitOps. Thank you.
Thanks. The explanation in video is short and but clear and understandable.
we are exactly using & following the same process, good to know follow this in detail and the global standards.

Very clear explanation! We'll have to change focus and start DevOps teams to develop their own CI/CD pipelines
Many thanks for the video Nana. A really very exciting feature for sys admins and net admins.

Excellent content as always. Thank you, Nana!
Thanks Dane, appreciate your comment :)
Nana explanation is amazing
Thanks Nana again, its helpful. I hope will do some hands on...
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?
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
great, concise summary as usual :)
Very helpful. Smooth explanation!
Thank you so much for this wonderful explanation!
So well explained, kudos to this kind of quality content!!!
many thanks. I did the gitops in my project for many years. But only now I realized it is called gitops
Congratulations from Brazil for the didactics and for the english
Crystal Clear explanation Nana. Great work !! Can you please make a video on Chaos Engineering and CHaos Mesh tool. Just a request. Thanks
Great video. Excellent explanation about GitOps.
loving your videos👏👏 .. very informative and easy language ..please keep making videos for us 🙏🏻🙏🏻

So good videos, dude, helped me so much 🤗
Your videos are wonderful, Thanks!
So clear and useful- thank you!
Hi Nana excellent content as usual. Tip: you probably need some phono absorbing panels to remove the annoying echo :-)
You can try surrounding the mic with stuffed animals or ruffled blankets.
Thank you for the great explanation! Easy to understand!
As usual AWESOME!!!!!😬😬😬😬😊
Love all your courses. Wish there was a course on Apache Spark from you.
i was just learning devops but this also makes me interesting.
Hey Nana, Kindly make videos on Network as code, Policy as code, Security as code, Configuration as code. 💯 Thanks.
very nice and useful video, my company flow is the same with your video. Pluse terraform enterprise, which has a queue for TF changes.
Thanks for the video, is so good, Saludos desde Perú! :3
hey Nana, thank you :) learning a lot from your videos
That's great to hear, thank you Akash :)
Your videos are great !!!!
Kindly, make a complete course material on GitOps with all Practical deployments and GitOps structure… end to end GitOps course please

How do you check your changes are good before making the PR? Do you have another environment for this?
I have the same question.Lets say I'm working on new yaml .where would I run it from my local before committing it ?
How do we ensure right configuration related to application is also going to multiple clients and multiple environments?
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.
Thank you Nana.
