Seriously, Nana, this is absolutely incredible. This is how it's done. This is a crash course not just in CI/CD but in how to make S-tier useful Youtube content.

[arunrai]

You not only know the material, but you are exceptionally great in structuring and explaining them concisely but in details, as a developer learning CI/CD pipelines I have no more words to express my gratitude! Thank you so much for your efforts.

[mtaghadosi]

You are actually one of the best DevOps teacher that I have ever seen. I already used so many of your free videos in Youtube when I was in another country which I couldn't pay for your products. Now that I am working as a Senior DevOps Expert in a German based company I happily be able to use your premium materials as well. Regards.

[hassaanqureshi]

Hands down the best intro walkthrough on GitLab CI/CD there is. Simply brilliant.

[juliocardenas]

Nana,

Your videos will take my career as a data scientist to the next level. I have now a common language with my DevOps colleagues.

Thank you for sharing your gifts with the world. I’m grateful and inspired.

[nbensa]

I have two decades of Linux/Bash over my shoulders, and I just discovered that you can mix pipe and conditional execution on the same line: `cmd1 && cmd2 | cmd3 && cmd4`. Everyday I learn something new. Thanks Nana!!! You're the best teacher in the world!

[allisonmachado]

I'm amazed just how WELL EXPLAINED were all the concepts in this video! Amazing, thank you !

[chandurdissanayake]

This is so awesome, your the best DevOps teacher out there. And I think we all appreciate you giving us free lessons like this and I hope you keep doing what you love for the free open source community ! :)

[uninconformemas]

It's absurd how easy you can explain things, you are simply the best teacher

[docteurplacebo]

I'm very new to CI/CD but my project desperately needed it. I'm very thanksful for this course. No loud music, no annoying and flashy things. Just the informations i need to understand.

Great job !

[kyabaatsharmaji]

Your tutorials are truly blessings for any s/w or devops engineers. Thank you so much ❤️

[kennedybacelar]

If someone is having the error "TypeError: required field "lineno" missing from alias" you can change the pytest version in the file src/requirements.txt - From pytest==6.2.2 to pytest==6.2.5 for example.

[jondoe]

Nana won't let you down, never doubt, no second thoughts when it comes to proper dedicated content.

[zeliwong]

This is the first time I really enjoy a lesson from Youtube! Very detailed explanation, in "human" words. Must of the times, I fall into lessons where the person explaining is very technical and for people like me, that is their first contact to any of those concepts, it can be terrifying.

Thank you very much, I will deffinitely continue learning from you.

[aydinahmadli]

I am impressed with level of simplicity yet straightforwardness in your explanations. Great job! Super fun & educative to watch your tutorials. Thank you.

[LetWorkTogether]

This is a perfect anatomy of CI/CD implementation! Thank you.

[HungNguyen-sixe]

Totally appreciate the effort of sharing and love learning everything from you Nana. You made everything possible for all beginners. Best wishes to you and your family.

[keeganbantom]

Brilliant crash course! I am already working on a CI/CD pipeline just by going through this video!
Thank you!!

Many thanks Nana for this great free video❤. There are a lot of videos available here, but I really like the way you mix demo and content. Furthermore you can explain perfectly these technologies 🤟I have learned a lot in this one hour. This will definitely help me in my daily business 😊 I very much appreciate this!
