Docker Networking Crash Course

Thanks, Hussain, amazing as always!

- One thing I'd mention is that I can run apt-get commands by exec the container as root user "sudo docker exec -u 0 -it <nameOrID> bash" if you do not want to install them in the Dockerfile.
- Can you explain how to allowt he container call the localhost, in my case I want the application in my container to interact with API that runs locally in my machine

Thx Hussein, this is one of the best Docker Networking videos 👍

Thank you very much for making the video. Learned very important thing about networking.

For local develpment I need to allow my host network to know/see and bridge network. How can I configure my network to do that? I use Ubuntu 22.04 and in Ubuntu 20.04 I can do that by default.

In my case I have a "mybridgenetwork" and have a defined ipam. My containers share this network and each container has a specific IPV4 IP.

From my host, I configure my hosts file to redirect the containers IP to specific URL (it's a complex environment).

Now in Ubuntu 22.04 I can't do that 😢

Someone have a magic trick?

Good tnx habibi 🙂

This is a really excellent video. thank you

Enjoyed every min of this video!!! This was FIRE 🔥, especially how you narrated the vid was funny. Kept me engaged 👌🏾

Pleae K8S networking tutorials and general k8s tutorials Save Our Souls Nasser!! ❤😢😢🥺🥺🥹🥹

Kubernetes Networking please!

thank u so much

But can you have an isolated network that can't directly connect to the internet through the host bridge but then use another network as gateway?

Awesome content 👍🏽

fantastic

300k subs... congrats and keep going HN !

best video for docker networking

Awesome video Hussein. Would love to see some content for Docker Compose too, as that's mainly how I work with Docker

Hi hussain, could it be possible if we don't create the gw container. But instead we create just the gw network and attach both of these containers s1 and s2 to that network?

Awesome video !
very nice and simple to understand !

Hahaha what a joke. Run some commands for a week, then make a crash course ahahahahhhahahaha

you have to make the network attachable to new containers with the ‘—-attachable’ option when you want to add services to an existing external network. And with overlay network options it gives you more flexibility. Especially when networking containers to swarm services.

Edit: that is if i understand your frustration with restrictive docker. Im a docker shill…

1010/1010 Video. Really amazing work :)

Great stuff Hussein. Thanks for putting this video together. Looking forward to your next docker video.

What about accessing localhost from a container ? In linux it’s ok but not mac and windows. Can someone explain that ?

I used ubuntu before and still got confused about networking when using docker in macos. This is very useful

Really enjoyable content and very high quality, many things got clarified along the way! Thanks for the clarifications!

One of the best video, a tiny error in image diagram where you swap the network frontend from backend and vice-versa

Mr.Hussein, if you happen to have a time could you please make a video or a paid course on how to design and build highload backend architecture and all that kind of stuff? For example how to build architecture which could support 10-50k requests per second, thanks for your work!

Hey , great tutorial ! Could you please 3xplain how gw container was able to forward the packets without any further configuration on the container ? I understand it has interfaces in both subnets and the rtb changes for s1 and s2 to use gw as gateway for those respective cidr ranges , but I still don't understand how it was able to automatically for the packets ...

Can you make a video on - Docker & Microservices

Your videos are a treasure trove. Thank you

Hey, what happened to whatsapp yesterday?

This video is awesome! very very detailed explanation about how container network works.

Can you make video about whatsapp outage, please?

great tutorial! I've learn a lot of networking watching your videos, thank you. About the DNS, is it possible to add an IP route rule to use the gate way container as the DNS for both S1 and s2?

is that how docker-compose does it in the background?

Hey Hussein
Thanks for this content.
I have a question, why you never gire a comparaison between open source database like postgresql, mysql and property database like sql server, may be I'm wrong ? 😊

Good job Hussein ... do something on k8

Awesome Hussein

this was such a nice tutorial

This was amazing, really enjoyed the tutorial
