Finally, someone who explains it at a detailed level but also doesn’t assume everyone watching is a networking expert. This was the perfect video for this subject

I always thought Docker was dumb when you can just spin up a virtual machine, but after watching this my mind has changed. You can create dockers WAY MORE QUICKLY than installing new ISO's to VM's!! Thanks for this!

Admit now.... We all want a Teacher Like Him💯💕💕💕💯

As Chuck said, if you are using the default bridge network you can't use the docker dns with containers name as ip address, instead you can use the id of the container and it will work fine. Also you can get a container id by the environment variable named HOSTNAME that is automatically created with the container, so this way you don't need to hardcode the id.

One network shortcut I like is “ip -br a” which hides a lot of the cruft and just lists the adapters and addresses.

This is probably the most comprehensive Docker Networking tutorial of any kind and it is under 40 mins. NetworkChuck you are awesome !

[thundergod]

Yeah, this is definitely what I needed right now. Diving into docker and had just a basic understanding of docker networking from prior use on my unraid server. Digging into the weeds of running my own docker containers managed through Portainer on a new enterprise server box I recently got for my homelab. The way you present this is just awesome!

[nate]

This should be on the official Docker page. Absolutely fantastic!!!! Loved the content. Researching this has been mind numbing, but this right here, is the jackpot. It's amazing how you dig into the actual networking while still keeping everything light and entertaining.

[Rick_Frigate]

So cool. As mainly a front-end dev, I'm finding out it's STILL unavoidable to learn a bit about containers, deployment and networking. I've memorized enough of the basic workflows to get me by, but your explanations actually have me UNDERSTANDING what's going on under the hood, and why! Love your lingo, your playful approach, and ESPECIALLY your drawings. Makes me feel like cracking open my laptop on a Saturday night! Thanks Chuck!

[RobbyPedrica]

I've been doing Docker for many years and it's still great to get an all-in-one summary of docker networking which can seem like wizardry at times.

[justindeemer]

Chuck, great video, thanks for keeping this entertaining, as this topic be a bit dry when researching it on the docker docs. One additional tip that I like to do with docker networking is switching the networks the containers are connected too or adding the containers to existing docker networks. Instead of stopping and deleting the containers, I just run 'docker network connect | disconnect <network> <container>'. You may already be aware of it, it's just something I like to use, as I hate rebuilding the containers. Thanks again

[classroomproject]

Seriously man, I haven't seen somebody so passionate explaining networking stuff. Thanks for the explanation and elaboration, it was fantastic!

[TheLimitedFusion]

This is perfect! I’ve been looking into learning more about docker and your videos always have the information I’m looking for.

[MK--Ultra]

The L3 IP vlan is amazing! Unique IP for each container is much better than trying to map ports to every container

[mikewang]

This is crazy. Diving in some topic in software engineering is not difficult. The hardest part is how you gonna begin with it. Your video is the best guidance for the beginners. Thank you!

[pimpedpixel]

This was by far the best explanation on docker networking I have ever seen. Throw away all books and watch this. Thanks a million. Great stuff

[morosis]

@9:35, rather than up a bunch of times use Ctrl+R, type a string match to the command you're looking for, it will lookup in your command history filtered by that string.

If the first result isn't it pressing Ctrl+r again will go to the next most recent one, etc.

[arcangelantonio]

Finally a real expert that is not scared to real time test-Lab/teaching amazing guy, all the best for Chuck!

[forgottenvy]

You know he's in serious mode when he's not doing it on LieNode.
