When I first saw that this course was from you, I bought it instantly from a crowded bus on my phone. I didn't even search for other alternatives because I think we are very like-minded when it comes to computer science. I feel like there aren't many developers like you who are just curios about how things work and want to have a clear understanding of the technologies they're using. I just hate when I have to quickly learn some new technology and not have the time to study it; only when things break you realize how little you know about it. I barely started section 2 and already love it. I'll definitely make sure to leave a review when I'm done.

@@ozoniuss1463 thank you! And I agree learning a new tech is not hard, understanding how actually it works is what interests me.

I've recently learned more about docker and worked with docker compose and network but I had this question that how could two container in different network communicate to eachother and I couldn't figure it out until I've seen your video and finally I got it. you're really cool and the concepts that you explain are really the hard things that one could think but not understand easily. Excellent work. please make more videos like this. Thank you Hussein Nasser!🙏

Secondly, please continue this as the series/playlist and also please include K8s Networking as well(I know it will take huge amount of efforts but that will be really appreciable).

For everyone looking at the Dockerfile. You should avoid creating too many stages within your docker file to keep your image small. Each command creates an image that you can explore (i.e) you can even intermediate images that lead to the creation of your docker image (like visiting your image after installing iproute2).

@prathamsinghal5261 Жыл бұрын

Of course we can do that! But Best practices can be followed at the production level but at the tutorial level beginners also might watch this stuff do for the simplicity he did that (I think)

What actually is the "bridge" in Docker? Is it the same thing conceptually as en.wikipedia.org/wiki/Network_bridge? Does it connect a host to the containers on a level-2 layer of OSI? If so, how does a bridge have an IP address? That Docker bridge sounds more like a router. @Hussein, could you explain that?

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…

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 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

As Hussein highlighted in video unlike Mac or Windows, Docker do not run on hypervisor on Linux so on Linux some of command results might change. Its normal.

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?
