took me a week to study in deep all the info you gave us, thanks you very much for your enthusiasm and dedication.
Regards from Colombia
Excellent really Awesome keep going Nana..
Reading the comments below, I'm so amped to start this course!!
it's sad that I can't like this video multiple times 🙁
Nice tutorial..Please add option for 15 seconds previous and next. It will be good.
It's really good explanation, can u make a vediis on Jenkins declarative file and. Ansible related to real scenarios
Congrats! These videos are excellent. You are an excellent teacher and professional. Very clear and methodical. Loved it!
This was absolutely awesome. Thank you. Liked and subscribed
This is a great tutorial. Thanks a lot. Nana, could it be possible to share with us your slides?
Thank you NaNa for very informative and well structured video. CONTAINER and K8 is always big mystory for me. I have spent 1hr in video and I am comfortable now and recommending to my friends.
Is this much of knowledge of kubernetes will enough to get started work on kubernetes in industries?
Many blessings to you Nana ❤️! You're God sent!
I am a fan of this new generation of tools with such powerful abstractions.
Haven't watched the video yet, felt like expressing this first. I've learnt from and enjoyed many of your other videos.
Thank you, for your work. I too appreciate it like many others. 🙏
I am not able to connect to container as it is giving me the below error:-
Error from server: error dialing backend: dial tcp 192.168.1.195:10250: i/o timeout
At 2:52:00
Does this mean that if I want to associate a username/password to access the volume, we can configure it this way or am I missing something here ?
Excellent and to the point explanation
Your lectures are truly very great. Very simple and clear explanation.
You are awesome.. Starting my 3rd complete course on your channel….
Very nice video and very well explained all the important concepts of K8s
I cannot believe a course of this quality is free on youtube. I might never use Udemy again unless Nana does not have what i look for. Please keep updating the content. Thanks Nana🙏
best Kubernetes tutorial till now. It has been a week trying to understand K8 with little luck.30 mins into the video and it all makes sence.
cool really thankfu grateful appreciated!
Your tutorial is simple and explain clearly about the concepts, thank you very much for your effort. I have a question, @12:50 , when we use ConfigMap to configure DB url , we don't need to rebuild the app, but we need to restart the app because of DB url change, right? ,
I used to wonder where are women in tech. I found you.
Why do ephemeral IP addresses exist if you can just always use the permanent IP address provided by Internal and External Service in conjunction with Ingress?
can some-one what is the editor used in the vedio pls .Thank You
Thank you very much Nana for this complete course!!!
You have explained each and every topic in extraordinary way. I never feel bore in comple journey of this course.
You're really an extraordinary teacher and having mellisonant voice.
I wish all the teachers teach like this!
Hi Nana, your courses are awesome.. It would be great if we can have a session on codefresh
Hi @TechWorld with Nana, I tried to simulate the demo in my virtual box, but I am getting status as ERROR as, "The warning MissingclusterDNS, Kubelet does not have clusterDNS IP configured and cannot create pod using clusterFirst policy". And I am using Microk8s not minikube, Is it a problem?
This course helped me a lot Nana…Thanks alot!!
Thank you so much
