[@basuutube]

I am from Machine Learning Background and trying to learn DevOps. Gone through many videos. To be honest, they are amazingly crisp. Can you please index the videos, like in what order should I go through to have a better understanding?

[@ravigiri_67]

Till 43 min everything was clear after that bouncer. Still appreciate your effort

[@akashmishra13]

Really great video...somehow this never comes on top when searching for microservices using python Great Work!!!

[@DevOpsMadeEasy]

Thank you so much :)

[@enterfonement]

Short and Sweet walk-through. Nice work.

[@chandu2155]

Frankly speaking, this is not microservice application(as we are not seeing two services talking to each other) , it's a service based web app deployed in kubernetes. Though the content is good for service based app. Great effort!!! Keep up the good work

[@DevOpsMadeEasy]

True. I have not extended this application to include 2 microservices. Thanks for the feedback :)

[@ifeanyivictor2857]

Hi @chandu kumar, please can you recommend a video that treated microservices very well.

[@akinyemisodiq7081]

thanks for this piece, even though i'm not a flask person, this tutorial is great, thanks

[@chhayadongre3956]

Really my search ends here for python...Great video. May I request you to please upload 04 video in this series, as i can see uplaoded videos are 00,01,02,03,05. Thanks in advance vikram sir 🙏

[@interestingdatascience8057]

Hi Vikram, It would be great if you take any MEAN / MERN stack application and show how to dockerize it and deploy it on Kubernetes through HELM. Because I am not able to find any solid video on KZbin where someone shown it perfectly so that we can implement the same in our project.

[@DevOpsMadeEasy]

I will definitely try. I don't have any MERN stack apps though

[@tom.bailey]

[@AlexandreSipauba]

Very good video! Congratulations and thank you for this content. But I got a little confused... Flask is a WSGI application. So who acts as the HTTP server for your application inside the container? In a production environment, a reverse proxy such as NGINX is required to prevent the WSGI server's built-in HTTP server from converting incoming HTTP requests to the WSGI server. So here is my query: Does kubernetes force a simpler architecture for k8s load balancing to manage everything from outside’s container? Or is the correct approach to keep an NGINX inside the docker container to handle the HTTP requests? I would really like to know.

[@Andrew_J123]

Hi! I appreciate the video and followed all the steps and got it working on my laptop. I wanted to ask if you're supposed to be able to see this on other devices though as I would like for things to be accessed by employers potentially. Thanks again!

[@DevOpsMadeEasy]

Once you build the docker image, you can deploy it in managed services like AWS ECS or AWS EKS to get a public endpoint using which others can access. You can also run the same image as container in AWS EC2(after installing docker) and access it via public ip of your instance

[@Andrew_J123]

@@DevOpsMadeEasy do you have any videos on these steps? It would be super helpful if you did. I think you give good instructions and basically want to use your videos as a base guide and then build apps using the structure you give

Great video thanks for helping, when you installed mini kube ? At 44th minute you said we have mini kube already installed, this video could be alot helpful if you add sections.

[@davidleal714]

thank you so much, great content

[@melodic_tech_house]

Had been doing all around 2 weeks

[@redemsion2]

Hi -Thanks for this video. I am learning from it. I have question. Why did you install python on your local machine rather than in a docker container? What are the benefits to installing it the way you did vs in a container? Thanks in advance.

[@ahoymatey1234]

Cannot connect to app when at the docker stage maybe it's something new but there seemed to be a rush through the minkube part maybe there is a special setup we need to that isn't shown

[@a1994s]

thanks bro, can you please make a microservice same as this video using Django

[@raghuvamsialapati585]

spot on tutorial. great work mate. could you provide the repo link. thanks

Anytime brother 😀

[@TheNishi42]

Thank you :-)

[@atzin.0603]

can I make a web page with this and selenium? to perform webscrapping on other web pages and display them on mine

[@DevOpsMadeEasy]

Yes you can

[@atzin.0603]

@@DevOpsMadeEasy it is something simple what I should do. is it necessary to use all the technologies of the video or could it only be done with django and selenium?

[@DevOpsMadeEasy]

Django and selenium are the dependencies. You should know how to containerize your app and rest all Kubernetes related files stays same

[@atzin.0603]

@@DevOpsMadeEasy So what do you recommend me to do what I have in mind? with kubernetes? thank you a lot

[@DevOpsMadeEasy]

The recommended way is to first dockerize your app, test it by running a container and then deploy the same image in Kubernetes :)

[@jaganmohan6557]

Can you make vedio on django web application framework insimilar manner brother

[@DevOpsMadeEasy]

Sorry, brother never worked on Django but I like Flask and Fast API compared to Django. Just a personal opinion.

[@thegreatindiankitchen91]

We were hoping one day you will release helm full course but we are losing hops sir please create a full course on helm

[@DevOpsMadeEasy]

We already have Helm complete course but a paid one. Full course is for our students

[@futhedude4848]

Great video with the Flask and Kubernetes, but this is NOT a video about microservice.

[@DevOpsMadeEasy]

You are correct

[@ajinzrathod]

So where exactly is Microservices used here?

[@chinmoypadhi]

Hi, I didn't get the step at 43:58 where you mentioned you have already deployed minikube and you are running "minikube start" from python virtual-env , the same when I'm trying to run python virtual-env , I'm getting the error (tutorial-env) C:\Git\microservices-in-python>minikube start 'minikube' is not recognized as an internal or external command, operable program or batch file. could you please let me know what are the steps to deploy minikube and kubectl so that I can complete this tutorial. It's good to have any youtube video link.

Implemented all the steps as per mentioned in video , all the containers and images are running fine , but when trying to load the minikube IP there is no result , its not loading the webpage, can u pls let know where could be the issue

[@DevOpsMadeEasy]

Did you exec into the pod and check if the app is accessible on the localhost? like curl localhost:5000?

[@partyplaylistsbyyash7540]

@@DevOpsMadeEasy got inside the pod , but none of the commands are working inside it , logged in via /bin/sh shell because when I was trying to exec into pod using /bin/bash getting OCI runtime failed error.

[@rohitvernekar]

Hey thanks for this wonderfull video : ) .I was able to deploy till docker compose.But while running kubernetes deployment, I am getting ImagePullBackoff status. I assume this is expecting a image. Not sure on where u created the image for kubernetes(webapp:1.0).

The same dockerized image is being used for kubernetes deployment as well. Check the video again and thanks for your valuable comments

Hi , when i am trying to load the webpage via minikube IP , its not working , checked on port mapping part , there is no as such port occupied by any other service. where do I need to modify

@@DevOpsMadeEasy still in docker build step only dint go to kubernetes setup yet (got stuck in docker build/run only) , after we did docker build and then docker run on port 80:5000 , then with that minikube IP the webpage is not loading. what could be the reason , because all the containers and images are running fine

[@DevOpsMadeEasy]

@partyplaylistsbyyash7540 For accessing docker container, use localhost only not minikube ip. Also I checked from my end and indeed minikube ip isn't accessible and it could be due to minikube issue. Don't worry the app should work in other clusters setup with kubeadm or EKS etc
