[@TheOliop]

Amazing... Thank you!

[@hamidoubalde2517]

This is awesome Nana.

[@user-lh6st6wo1g]

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 KZbin content.

[@arunrai80]

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.

[@TechWorldwithNana]

Thank you, really happy to hear such feedback! :)

[@alvaurah]

For those who might have import error when running make test... this maybe could help add this in the requirements.txt pytest==6.2.5 Werkzeug==2.2.2

[@thewarrior9827]

Genius man 👍

[@chetanthakre9327]

thanks bro

[@Rosalind1981]

thank you! I'd just got stuck on this part, appreciate it

[@kennedybacelar7959]

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.

[@mishadsl9848]

Thanksman

[@TheMUxambazi]

Nana, we Georgian Devs are proud of you as the symbol of the Georgian woman's power(especially from Samargalo

[@kyabaatsharmaji]

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

[@HungNguyen-si2xe]

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.

[@fb6868]

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!

[@allisonmachado]

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

[@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 KZbin 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.

[@zeliwong]

This is the first time I really enjoy a lesson from KZbin! 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.

[@hassaanqureshi6479]

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

[@docteurplacebo5888]

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 !

[@technicalilm8999]

This is the most complete tutorial I have ever seen. Thank you so much Nana.

[@aydinahmadli7005]

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.

[@maverickvasu]

i have not seen a better teacher than you in recent years . you are tech savior for human kind. This is not my job, but still love learning the tech stuff . I thoroughly understood and enjoyed the tutorial

[@uninconformemas]

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

[@rastostana]

This was truly helpful as an intro into GitLab CI CD. Thank you Nana!

[@BryanDike-vh2fj]

You are amazing Nana. Thank you so much! I find your videos incredibly helpful. You make the most complex concept easy to understand.

[@chandurdissanayake9544]

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 ! :)

[@kgottsman]

She explains things plainly and is a great reference.

[@TechWorldwithNana]

Thank you Chandur, really glad to hear! 🤗

[@ashimov1970]

absolutely agree! Long live Ukraine and free Georgia!

[@metaphormachines]

i am really good at explaining somethings so how can i be like you? i will create an youtube channel but dont know how to visuliaze what you want to tell people@@TechWorldwithNana

[@FirstLast-fc9cu]

Nana I am thoroughly enjoying all your devops related videos and when I can afford to will do your bootcamp course. I love how clearly and simply you explain the tools and concepts.

[@mohammedkaram8606]

Nana, you can't imagine how happy I felt when I found this tutorial You are amazing, every tutorial I watch from you makes me very excited to work in this field more and more Thank you so much for all what you are providing for us 😍😍😍

[@samvelsiradeghyan5510]

If you are creating everything from scratch, most probably for deploy stage job will fail and you will see this error in the logs: "docker stop" requires at least 1 argument. See 'docker stop --help'. Usage: docker stop [OPTIONS] CONTAINER [CONTAINER...] Stop one or more running containers "docker rm" requires at least 1 argument. See 'docker rm --help'. Usage: docker rm [OPTIONS] CONTAINER [CONTAINER...] Remove one or more containers Just use -r with xargs like this: docker ps -aq | xargs -r docker stop | xargs -r docker rm It will fix job fail.

[@purvakmistry2128]

Hats off to Nana and team for creating such awesome, valuable content! Too good!

[@milansingh3222]

These are all precious materials I can say we will not find nowhere . So so happy and now I have basic idea and confident to move ahead. Thanks Nana as always.

[@keeganbantom2999]

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

[@modvoip6836]

That is one hell of a tutorial, thank you very much! You have a talent to explain it easy!

[@habrazilay]

As always your explanations and teaching way is clear, simple and understandable! Thank you so much Nana!

[@jondoe79]

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

[@hollisross3561]

Your guide is the absolute best guide for me. It has just the right level of detail, tricks and overview of the technology. I'm a fan for life. Thanks!

[@anikbarua4834]

Finally, I understood the CI/CD in GitLab. Thanks a lot for the complete real tutorial.

[@siomarapantarotto]

Fantastic! Great tutorial by an awesome instructor. Thanks, Nana! Love it! ❤

[@juliocardenas4485]

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!

[@tomstagnaro]

For anyone who ran into error " "docker stop" requires at least 1 argument." or similar, you must remove the yaml script line "docker ps -aq | xargs docker stop | xargs docker rm &&" the very first time you run this. Because the remote server (in this case DigitalOcean) is looking for the result of the "docker ps" command which don't exist yet. After running it the first time you can add it back in and it will work from then on.

[@benschoen3035]

Hi, I had the same error, but I believe there is an easier way. The xargs command takes an option '-r' or '--no-run-if-empty' which skips the command following it. So, I changed it to "docker ps -aq | xargs -r docker stop | xargs -r docker rm"

[@CoreyMinter]

Awesome video, literally one of the best tutorials I've ever seen and I've been a developer for over 6 years. I appreciate all the visualisations and edge cases. Thanks a lot! : 3

[@TechWorldwithNana]

Thank you, so great to hear :)

[@brunomadeira5236]

I really appreciate the amount of effort you put into the presentation. Definitely, the best tutorial I could find on the topic

[@siphiwemthembu8720]

As an SQL DBA, I can confidently embark on DevOps learning with you at any time and begin applying the knowledge in practice. Your approach to learning is highly efficient. By focusing on teaching 20% of the most important material, you enable learners to comprehend 80% of the subject matter, truly exemplifying the 80/20 rule.

[@renends7615]

Your channel is spectacular! The didactics used transforms something complicated into something very simple. Grateful!

[@ravisinghatia5885]

I have never watched such an awesome tutorial till now, great explanation and covered all the possible errors that can come. Really helpful Nana, Thanks

[@joseardilag]

Amazing, clear and useful as usual ... great job done!! Thank you so much for keep on sharing your vast knowledge in DevOps

[@AbdulBasit-en2yi]

Exactly what we needed, to the point knowledge about the gitlab CI/CD pipelines. Thanks for the good content, and effort to make it.

[@markjones7822]

This is the first time I have watched any of your videos and I want to say great work, I have finally got round to fully watching this video and it really helped me understand pipelines. Keep up the good work.

[@princeogabi4397]

This was a bit daunting yet simple to understand. Thank you Nana. God bless you mightily!

[@duncanyu4548]

Tried locally running the test and run on Macbook Air M1 (Jan 31, 2024). Changed a few things in the requirements.txt file: Flask==3.0.1 py-cpuinfo==9.0.0 pytest==6.2.5 Issue was Jinja2, markupsafe, and some other apps deprecated some named exports. But some Google results say that getting newer versions of those 3 above is sufficient.

[@Joselson14]
