I have taken many courses from Udemy and all. But I must say this is the best course so far on Devops. Very simple way to explain lot of new things, concepts. Loved this 45 days devops courses. Absolutely awesome.
I've been postponing this topic for a long time because I find no perfect video for me to comprehend this topic. This guy put everything in a simple way. Thanks man ;) God Bless you.
@@AbhishekVeeramalla hey abhi can you clear my doubt in the comment section....Hey Abhishek thanks for the wonderful explanation. I have one doubt in this time stamp 20:10 so here we are using the custom bridge to isolate the container. Here is my question -- even a custom bridge network also coming from the host right as per your diagram. How is this container secure?
Thankyou for teaching this concept in a very crisp and easy manner, Before I use to be scare of docker networking. but now i am pretty confident about it
I purchase course from udemy and tried to understand docker networking but it was not clear to me. Thank to Abhishek sir for best and bestest explanation.😊
at 30:40 the host-demo container is created with host network name. so it will have completely different ip since its different from the bridge network and newly created custom network. Thank you for this valuable content. Clearly understood the implementation of the network in docker.
just write the command : docker exec -it host-demo /bin/bash .It takes u to the host section and there u see root@Ip address which is your host machine Ip. But in network section u didn't get it. @@bhanuteja_04
The answer for the question that you asked us at @30:30 i.e. the IP address of the host-demo container would be either nothing or something in the subnet of the host network. Thanks for the wonderful explanation Abhishek.
Hi Abhishek, Thank you for valuable content. I was searching for some one who gives me clear understanding about devops what to learn, how to proceed step by step. Luckily I found you through LinkedIn post from some person, and I got answers to all my confusion regarding Devops. Kudos to you. I have the following questions Abhishek, Q1: For suppose I have created a container with default bridge network or host network or custom network, but later stage I want to change the network to different one. Can I change without deleting the container? Q2: Host is communicating with different containers with different networks. Can we make the same among the containers? What I mean is can only a container in the same host have multiple networks so that it will communicate with different containers? Thank you.
Docker networking allows containers to communicate with each other and host system. Two scenarios, Container one connects to container two, Container one has isolation from container two. When you create a container. Docker creates veth, That is docker0. It allows docker container subnet to communicate with host. It is called bridge networking and it is default networking in docker. If there is not veth/docker0 the containerized application is not reachable from internet. So users will not be able to access application.

If there is no veth/docker0 the containerized application is not reachable from internet. So users will not be able to access application. Other ways of networking in docker.. 2. Host networking - the container will directly use network of host, bind eth network of your host. Whoever has access to host have access to container. Least secure way of networking in docker. 3. Overlay networking when you need to create a network that is common in all the host of Kubernetes/swarm cluster.
Recently I started following you, Your explanation is really awesome it makes people to understand easily, appreciating your efforts bro ...pls continue the same.
Good session Abhishek bro. One good point your session is person without much technical background can able to catch and since you are not using any typical corporate English words ,we are able to adopt video easily in simple language .
I feel very fortunate , lucky to associated with you and enhancing my skills . This is a perfect example where you illustrates typical Docker Networking in simple terms and make things understandable . Keep enriching us with such knowledge .😊😇🙏. One question except the Timestamp that How this Networking models can co relate with AWS & other cloud or how we can integrate ? Please make a video on this . Thanks a lot in advance again .

Thank you so much for explaining this networking concept in very easy and clear way. If you have time could you please create a short demo for Overlay network. Thanks in advance.
Hi RKtech, I can do that but frankly it will not be of much use for the efforts as overlay networks like calico, sdn can be installed much simpler way once we move to Kubernetes. But I will try to do that If I find some time
21:20 what is detach mode ? and you are using docker run (when you created that containers) i don't understand we don't need to build container everytime ? please explain me
hi abhishek videos are great. can you do a favour as you have different videos on interview questions on every tool , can you merge them all and make a long video like mostly asked devops interviews questions or important devops interviews questions like that. it would be very helpful for the students to prepare for the interviews and you can also add new questions into that also. i wish you could see this message.
i had clone your repo and got your files named Docker-Zero-to-Hero. but on 21:12 when you writing command ls I am not getting file first -docker-file and golang-multistage. Please correct If I am doing any wrong
Thank you Abhishek for explaning about docker volumes i have a question how docker manages multiple volumes or storage volumes must be using resource like disk space from host os how storage is managed here pls clear this doubt @Abhishek
hey abhishek i have a doubt here if my host is on xyz range ,then the containers address will also be the same if i were to create the container in that host right?
Abhishek I have to ask question, how input container will talk to Finance container when it is required since we have separated using custom bridge network as front end has to talk to backend.
Hi @Abhishek , 31:00 container was created with host network, and ip address corrsponds to host machine, how do we access that container if we have to ?
sir you are best I have one question regarding Cloning Repository. Sir is it neccesery to clone your Repoitory to do practice or we can create our own?
Hello Abhishek i have a doubt..(31.36) When we run the container using the host network we can access the container using the host ip ..then..why dont we see the ip of the host machine in the network section when we inspect the container using the host network?
Time stamp 4:10 - can we consider container c1 and c2 as microservice 1 and microservice 2 , since containers are deployed as microservice or how pls clarify. TIA 😊
i did it i created custom bridge network ,i tried to ping it from default bridge network container it doesn't work as you did. but the question is when i tried to ping container that have default bridge network form custom bridge network container why it not woks as the are on the same host.... thanks for the great videos..
#Network driver summary 1)The default bridge network is good for running containers that don't require special networking capabilities. 2)User-defined bridge networks enable containers on the same Docker host to communicate with each other. A user-defined network typically defines an isolated network for multiple containers belonging to a common project or component. 3)Host network shares the host's network with the container. When you use this driver, the container's network isn't isolated from the host. 4)Overlay networks are best when you need containers running on different Docker hosts to communicate, or when multiple applications work together using Swarm services.
i have one question if bridge network error like container on the same host it will generate different subnet of each container how to resolve issue related bridge networking?
@6:36 Brother I have a doubt, we are launching the host in one specific subnet, but when the container get created in another subnet, how is it possible

Hi, Question :
At 14:33 doesnt C2 have its own docker-0 which gets binded to the host network?
Thank you sir 😊
Abhishek I have to ask question, how input container will talk to Finance container when it is required since we have separated using custom bridge network as front end has to talk to backend.
Hi @Abhishek , 31:00 container was created with host network, and ip address corrsponds to host machine, how do we access that container if we have to ?
By access do you want to login ?
good
sir you are best I have one question regarding Cloning Repository. Sir is it neccesery to clone your Repoitory to do practice or we can create our own?
Anything is fine
Hello Abhishek i have a doubt..(31.36)
When we run the container using the host network we can access the container using the host ip ..then..why dont we see the ip of the host machine in the network section when we inspect the container using the host network?
Because you are inspecting the container not the host if you want to see host ip hit this command "ip addr show
"
hi abhishek i have one doubt what is docker compose can please explains
Is there any way login container can talk with finance in case any specific app from login need info from finance?
Time stamp 4:10 - can we consider container c1 and c2 as microservice 1 and microservice 2 , since containers are deployed as microservice or how pls clarify. TIA 😊
Yes
i did it i created custom bridge network ,i tried to ping it from default bridge network container it doesn't work as you did.
but the question is when i tried to ping container that have default bridge network form custom bridge network container why it not woks as the are on the same host....
thanks for the great videos..
Thanks..... What about docker service, docker swarm and docker compose
We will not cover them in this course .. May be sometime after this course as many people are asking for docker compose

i have one question if bridge network error like container on the same host it will generate different subnet of each container how to resolve issue related bridge networking?
very helpful :)
15:30 if we use bridge network too i guess it's fine as our instance will be in a private subnet....am i right in this case?
@7:45 Is virtual network and virtual ethernet same ?
@6:36 Brother I have a doubt, we are launching the host in one specific subnet, but when the container get created in another subnet, how is it possible
A seperate isolated network is created for the containers and this netowrk is shared with the hosts.
By default the network created is bridge network.
I use podman, I followed your tutorial, my finance container can talk to the others on different bridge?
By default no
After Docker Image and container creation then how to run image through cli?
If multiple containers are created on the same host , are all containers connected to the same veth by default
@abhishekveramalla anna - how do the containers communicate after restart as ip and hostnames are dynamic ?
You will learn exactly the same thing in next classes
thank you so much@@AbhishekVeeramalla excellent work, i wish you grow more and more.
where is the nginix:latest docker file and it is not available in the git repo as well
Please explain about docker compose
After creating a custom network , how can we communicate with that container ?
