Hi Friends, I am Anshul Tiwari and welcome to our youtube channel ITkFunde.
About this video -
In this video let us understand containers. Application containers are fast becoming a new norm to package, deploy and ship applications across platforms seamlessly.
Before we understand containers, we need to understand the basic difference between a physical machine, a virtual machine and a container.
Physical machines can host only a single environment and application whereas virtual machines with the help of Hypervisor technology can host multiple VMs on top of the same hardware. Every virtual machine has its own Guest OS running on top of HOST OS.
Containers, although work on virtualization concept is very different from a VM in the sense that a container does not, has its own OS, it directly runs on HOST OS which makes containers very lightweight compared to VMs.
Benefits of Containers -
1) Logical Packaging
2) Containers are faster than VMs
3) Less Memory Intensive
4) Easy to deploy
5) Reduce delivery time
6) Help Dev and IT Ops
7) Fewer Bugs
5 steps to create a docker container -
Step 1 - Develop Application
Step 2 - Create a Docker File
Step 3 - Build a Docker Image
Step 4 - Build a Docker Container
Step 5 - Push to Docker Hub

[@udaypatel83]

Whats unique about ur videos are ur example. The example of Fish is something which really makes it different. Great job once again! Thank You.

[@ITkFunde]

Thanks once again Uday🙏

[@ANJALI4IMS]

The way you explain and the examples are amazing ... even a non IT background can understand it

[@ITkFunde]

Thanks Anjali that is my mission making IT interesting for everyone 🙏☺️

[@vivekanandkondaparthi3017]

Thank you for the EXCELLENT tutorial. Keep it coming..

[@moneshal8566]

Super great glass for beginners trying to understand containers

[@avidlyviewed]

Anshul - I wanted to thank you for again a fantastic way of explaining concepts through simple relatable examples with no jargons. Having said that as some one in IT related field (as a non developer) I have always had problem when you say Application, its dependencies, run time etc. As you have called out your series as IT Ke Fundae, it will be really helpful to take a simple application (pseudo code say in Python/Java) using some library ,explain binaries, run times etc. Much like the Aquarium example, if the next level detail of what is packaged in a container. That will be really useful. I am not sure every one feels that way. Also the issues in large companies where in various environments are not having the same dependency is a real issue. So another one showing how that code will be taken through lower environments and then production deployment will help.

[@ITkFunde]

Thanks Anand for feedback and suggestion, I have made some practical videos on containers on GCP will try to do something based on requests for the same

[@gurramramesh484]

Superb explanation and your examples will be Awesome..please upload recordings on Ansible

[@ITkFunde]

Thanks Gurram

[@rajasekharareddy4584]

In VM example you've mentioned type-2 hypervisor, which are not that common to run enterprise workloads, but type-1/bare metal hypervisor scenario, guest os can directly access H/W, no host os involved,

[@dgsharma3299]

Pls show once clear pic of your display board so we get full picture :)

[@nageshgoud7629]

hi sir really very great explaination and nice video, thank you. please i request you to do how it will be in cloud like in AWS(containeraisation)

[@mkishore3920]

Om gam ganapathaye namaha..

[@sunilghorpade5004]

Please make more videos .

[@ITkFunde]

Sure

[@crazytravels]

Hello Friends,
One doubt - If the dev image is pushed as it is to the docker hub then is it used as it is in production?
How the dev DB connection string is changed to prod DB connection string? and where it is done?
thanks!

[@sravanikambhampati1491]

Videos are really helpful. Could you please make a video on self-signed certificates for k8s application?

[@vijayakumar-ur7zz]

I have 2 questions..
1. docker container anyways need OS right? in the video example it is ubuntu..
2. How many containers we can create in a machine? is it dependent on number processors?

[@MandeepSingh-yq3xl]

👌👌👍👍

[@vigneshkini9489]

could have been much better as i have seen other videos

[@ITkFunde]

thanks for the feedback i will try to improve

[@coppernix6914]

I should take this opportunity to thank god and specially this unknown GURU _/\_

[@ITkFunde]

Thanks Copper for your wishes it means a lot to me ,🙏☺️🙌

[@amar123ful]

Boss, video content is good. But low sound.

[@bhavithasaiyendrathi6861]

Hi IT k Funde thankyou so much for making these videos. I have one question though
Q. I have an application built on unix os
My QA owns a windows machine with Docker installed on that windows machine.
Now will this application which was built on unix os run on windows os.
Since you mentioned containers use the host os to run the containers but i need unix os to run app and host os is windows.
How will this work?
TIA

[@adetunjiagbayewa7352]

There is a docker image to run light weight linux on top of windows. The QA will download this and import your own YAML or you like the app directory to the container. its been a while i tried this but this is how you should approach it

[@appleskitest1]

Imagine creating a docker container for a hello world application

[@hugemuscles100]

killer beard!!

[@ITkFunde]

Hahaha thanks for appreciating the most underrated feature ;)

[@nirajsparihar]

Bro just improve the mic voice modulation is fluctuating in between. Hope u take this as a feedback
