Amazing... Thank you!
This is awesome Nana.
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 TH-cam content.
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.
Thank you, really happy to hear such feedback! :)
Your tutorials are truly blessings for any s/w or devops engineers. Thank you so much ❤️
I'm amazed just how WELL EXPLAINED were all the concepts in this video! Amazing, thank you !
You are actually one of the best DevOps teacher that I have ever seen. I already used so many of your free videos in TH-cam 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.
This is the first time I really enjoy a lesson from TH-cam! 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.
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 !
Hands down the best intro walkthrough on GitLab CI/CD there is. Simply brilliant.
I am impressed with level of simplicity yet straightforwardness in your explanations. Great job! Super fun & educative to watch your tutorials. Thank you.
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.
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!
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.
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.
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!
It's absurd how easy you can explain things, you are simply the best teacher
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 😍😍😍
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.
Nana won't let you down, never doubt, no second thoughts when it comes to proper dedicated content.
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
Thank you, so great to hear :)
I fell in love with the description. Really perfect course. No boring, no wasting time. She is answering immediately all questions on my mind when watching.
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
Hats off to Nana and team for creating such awesome, valuable content! Too good!
Brilliant crash course! I am already working on a CI/CD pipeline just by going through this video!
Thank you!!
Finally, I understood the CI/CD in GitLab. Thanks a lot for the complete real tutorial.
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 ! :)
She explains things plainly and is a great reference.
Thank you Chandur, really glad to hear! 🤗
absolutely agree! Long live Ukraine and free Georgia!
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
This is a perfect anatomy of CI/CD implementation! Thank you.
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!
Контент - в кайф!!! 👍👍👍👍👍 Самый доходчивый пример!!! 👍👍👍👍👍 Не останавливайся и БОЛЬШОЕ спасибо за твой труд!!! 🙏🙏🙏🙏🙏
That is one hell of a tutorial, thank you very much! You have a talent to explain it easy!
This is the most complete tutorial I have ever seen. Thank you so much Nana.
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.
Fantastic! Great tutorial by an awesome instructor. Thanks, Nana! Love it! ❤
You are amazing Nana. Thank you so much! I find your videos incredibly helpful. You make the most complex concept easy to understand.
As always your explanations and teaching way is clear, simple and understandable! Thank you so much Nana!
This was truly helpful as an intro into GitLab CI CD. Thank you Nana!
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.
Thanksman
Your way of teaching is very open, simple and authentic. I learnt many things from your tutorials. Thank you so much for delivering very important concepts so easily, with open mind and heart with real intention of teaching others. 🙂🙏
Thanks so much Mubbarik, what an amazing feedback 😊
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
Genius man 👍
thanks bro
thank you! I'd just got stuck on this part, appreciate it
Awesome tutorial! Learning so much and I love the tempo and how well explained! Makes me less afraid of devops 😅
Generally I don't comment on TH-cam videos, but this tutorial is ultimate on GitLab CI CD, hats off to you
I really appreciate the amount of effort you put into the presentation. Definitely, the best tutorial I could find on the topic
Your channel is spectacular!
The didactics used transforms something complicated into something very simple.
Grateful!
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
Amazing, clear and useful as usual ... great job done!! Thank you so much for keep on sharing your vast knowledge in DevOps
Elaborately given the fundamental concepts for Gitlab, thank you! And plus the tone of her voice is amazing as a tutor. After watching a couple of different tutorials with a voice triggering my misophonia, this video record saved me 💚
Exactly what we needed, to the point knowledge about the gitlab CI/CD pipelines. Thanks for the good content, and effort to make it.
JUST EXCELLENT! TOO GOOD Nana and team!
@Nana, You are really gem at your presentation, especially a person with medium knowledge also can easily understand your classes. Keep rocking always. Thanks !
This was amazing! You deserve every ounce of success you are having. Respect!
This was a bit daunting yet simple to understand. Thank you Nana. God bless you mightily!
An excellent tuto! Thank you very much Nana for this great work, it helped me a lot to start with gitlab CI/CD
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.
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"
@@benschoen3035 aha. I wish I knew that for past 15 years. Thanks
@@benschoen3035 Thanks
@@benschoen3035 Amazing, thank you very much

So professional, thank you for calm and comprehensive explanation ❤
one of the best precise videos on CI/CD on gitlab.
I wanted to express my sincere gratitude Nana🥰 for your GitLab CI/CD tutorial. It has been immensely helpful as I prepare for my final internship project in the coming month. Although I couldn't deploy due to the lack of a subscription, I want to assure you that understanding the process was the most important for me. May God bless you for sharing your knowledge.
Thanks for explaining things very simply and straightforwardly!
Just in time. Thanks for your work!
What a clear and simple explanation ! Thank you.
This is amazing! Love it, great tutorial, thank you ❤
Hi Nana. Thanks for the wonderful session. Loved it. Appreciate your effort and I am fan of your sessions.
No words are enough to thank you for this AMAZING content.
I must say that you know a learner's mind very well. The next explanation from you is always the first question that comes in a learner's mind. This might sound a simple thing but a very very rare quality.
Awesome; thanks so much for providing this tutorial.
Thanks for your continuous support. It was a great lesson that anyone could understand.
Now I can read and understand ci-cd files. Thank you Nana!
Превосходное видео!!! Это помогло мне структурировать информацию в моей голове. Огромное спасибо!
That was a very clean and clear explanation of Gitlab CI/CD , thank you so much :)
Very nice explanation of GitLab. I used a GitLab Server and implemented everything on AWS. I ran into some issues, but I eventually got everything to work.
AMAZING!
EPIC!
Thank you super much!
Nana - Amazing detailed explanation...This is what I was searching from a long time. All In one,
Excelent! Thank you for this awesome course!
I learned so much from this crash course. Thank you Nana.
Thank you, this explained some very basic concepts that I was missing as I began working with gitlab.
If you are starting this project fresh today. You will need to change the requirements.txt file to the following: "Flask=2.1.0"
Once you do that, the first step of completing "make test" should work(2)
I had this problem too - turns out it's because I cloned the repo from the original GitHub page. Nana actually fixed this already in her own fork on GitLab! 😂
Thank you! Currently working to get an IaC scanner integrated into GitLab. This was immensely helpful!
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.
Thank you!
Everytime you comes with the much needed skill-set which ppl r looking for...i know i've said this several time but i really appreciate and value ur work...it takes a courage and big heart to do this stuff for free...Huge thanks @TechworldwithNana...wish u a million subscribers soon
