How do Docker Containers communicate using networks?
If you have gone through all the tutorials in this series, you should know that well by now.
Introduction
This blog is the 8th and last tutorial in a series for Docker Networking.
- blog #1 - Why is Networking important in Docker?
- blog #2 - Basics of Networking
- blog #3 - Docker Network Drivers Overview
- blog #4 - None Network Driver
- blog #5 - Host Network Driver
- blog #6 - Bridge Network Driver
- blog #7 - Overlay Network Driver
If you are looking to learn more about the basics of Docker, I’ll recommend checking out the Docker Made Easy series.
Summary
In this series, first we answered “Why is networking important in Docker?”.
Then we learnt about some core networking concepts like the Internet Protocol (IP), network interfaces, subnets, network ports, DNS, etc.
Then we discussed about Docker Network Drivers, which is how Docker hides the network details and simplifies how to attach different types of networks to containers.
We then dived into the of the 4 main Network Drivers:
none driver - isolates a container by disabling its network.
host driver - allows the container to share the network stack of the host system.
bridge driver - creates an internal network within a single host.
overlay driver - creates a distributed network able to span multiple hosts.
For each of the Network Drivers, we learnt how to use it, some possible use cases and their limitations.
Conclusion & what’s next?
Thank you so much for making it so far! 🎉 🫂
It has been a great pleasure and learning experience to share about Docker Networking with you. I myself got to learn many important concepts and details in the making of this series.
