Containers are lightweight in nature. As they don't have complete operating system Container have minimal operating system that is base image. Container is a package/bundle of application that has all the application library and system dependencies like python. Very easy to ship and transport as they are lightweight in nature. As they use resources from base operating system.
This was the best introduction video ever, I have come to watch it again for interview, I recommended this to all my organization friends who said docker went above their head and today they are thanking me for showing them this playlist one of them even cracked interview with ease now I too will with the confidence I have gained from your videos in this era where people try to earn money by looting students and making studies a business, Some of us could not afford as most salary went in family responsibilities but you made it easy for us , May god bless u sir and you have more more more most success in your future ahead
I have seen lot of videos about docker containers but i did not understand. After watched this video i got interest to learn docker. You have made it very simple and clear. Thank you so much.
Thank you very much Abhishek for the detailed explanation.. I watched multiple videos to understand what is docker & containers still I was confusing.. after watching this video now I understood how it works and what is docker and containers.
Question: Does docker deployed on VM will share the libraries and resources with VM OS with VM Hots image. I mean if we have windows as host image on top of that we have Ubuntu VM and on this VM we deployed the container, so do the library and resources from host in this case windows is shared with the container?
Abhishek Garu, thank you for sharing the content. Your guidance has been invaluable to me, and I deeply appreciate your respectful approach as a teacher. God bless you.
Sir your clarity of explanation is top notch a telegram community will help very much Thankyou very much sir. I am looking for resources any on how to contribute to open source projects with this knowledge without knowledge of coding
Hi Abhishek , you mentioned to reduce cost we are using containers , but at 12:09 you’re mentioning that we need to create containers on top of ec2 isn’t this same again ? If that’s the case we are using vm and container both right . Can you please clarify if I misunderstood thanks .
I hope u watched previous video. I explained this in previous ones but thats ok, let me try again. Using containers you make the most use of vms or bare matel, wherever the continarization is being performed.
Hi Abhishek Can we use this docker and kubernetes playlist concept be implemented in azure devops also. Because in azure devops ci/cd pipeline creating you have used docker images.
Docker engine is single point of failure. If docker engine is failed, container will go down, so to avoid this. Buuldah tool will sove this as well as problem of image layering. Using shell script .You can also create docker image or oci using buildah.
Hi Abhishek, One question at the time stamp point 24:15. As mentioned we can create a docker image using builda my question even to create a docket image from builda we need a docker engine? If not what is the integration process here. Can u please elaborate ASAP
Hello Abhishek, Thankyou for sharing the videos. just a quick doubt , do you check and maintain these videos for any new changes happening in technology?
EDIT : GOT ANSWER TO THIS QUESTION IN K8S ARCHITECTURE CLASS,TQ. Hi Abhishek, now a days it's been said that docker containers in k8s are replaced by something called cri(container runtime interface) and there is a standard set for containers by oci , is this buildah is the one kind of thing which replaced docker containers in k8s?
Hi Abhishek, Thankyou for providing the wonderful content. I was little bit confused between physical systems, virtual systems and containers in terms of memory usage, resources utlization etc. For suppose let us take the case of windows operating system installed systems, in physical systems, it requires minimum 4 or 6 gb as minimum requirement mentioned by the windows to perform correctly. But when cominig to virtual server, how 1gb ram is supported to run the application. and also coming to container, as it will be light weight which is of 100 or 200 MB, what is the major difference among them.
Hlo Abhi Anna, Definently we need to upskill more about docker. but Is this 7 docker content videos is fine to learn and perform in the job as a non relevant experience job holder.
@Abishek.Veermalla. I need Help on linux after executing the systemctl status docker command in ubantu. MAY I know wht will be the command to write command for the further action .after this lines 1-21/21 (END)
Hii brother, I am Ram . iam following your videos since a month , the videos are useful & informative for me. Also can you please guide/ advice to me to a good resume ....
Am fresher abhisek, are the handson project enough to get internship? Btw big fan of ur teaching skill. Tomorrow if u put out any paid devops course I will be the first student just do know, not to mention I attended Praveen singampalli's course but lot of unknown useful things get to know from u, somehow I connect with u more.
Great explaination Abhishek Went through Udemy course also to understand topic but your explanation is far better than that course❤ Really appreciate your work🎉
Anna, could you please also do videos on AWS. I found AWS play list in your channel but there are no complete videos. Please look into it when you have time. 😍
Hey, day 23 is the first video, don’t worry. The docker playlist is part of the DevOps Playlist, so it is day 1 for docker but day 23 for devops playlist
Hi Abhishek Thanks for wonderful session , But still I did not understand how containers use memory efficiently. Lets say if VM is 10gb , if my application in container using 2gb of space. Still we are not efficiently using the space right?
@@AbhishekVeeramalla Planning to start it once I complete your AWS series. I really loved your explanation of VPC concept. It was one of the best explanation ever.
It's a good question and yes it's possible to attach volume while the container is running without restart: docker container exec -it my-container mount -t local /dev/sdX /path/in/container Local nothing but type of volume.
Bro at last try to make a video take a source code. Using all the resources how to deploy the application on real time like by using docker, k8s in Aws
This is so brilliant . God bless you Question : would can someone who is learning with azure follow through with your projects ? Or is it advisable to just use aws ?
Hi Abhishek, I have been learning docker there are few queries about building my own docker image's. I have zero knowledge of software development frameworks like django,flask and nodejs, so my worry is how will a DevOps be able to write Dockerfile for different applications. Do we need to have clear understanding of software frameworks??.. Please clarify Abhishek.

Abhishek if ec2 is not using fullest cant we apply autoscaling to it to reduce the volume??

You are explaining in a understandable way. Is there any notes as well?

We have load balancers and auto scaling right, in that case depending on load only we can create the machines using auto scaling right. Just doubt
