A beginner’s guide to networking in Docker

In this lesson, we are going to understand how host-to-container and container-to-container communication takes place. Since this won’t be an advanced guide, we are only going to explore the surface of networking in Docker.

In the previous lessons, we learned a great deal about Docker, Dockerfile, Docker images, and Docker containers. We understood the isolated nature of a Docker container and how to connect with a running container using -p (_or __--publish_) flag to map a host port to a container port for network access or -v (_or __--volume_) flag to access files of a container from the host.

In this lesson, we are going to talk about the networking aspect of the containerization process. We will explore what different options Docker gives us to control the network of a Docker container and how we can use them depending on our needs.

Docker network is a medium through which a Docker container can talk to its host, other containers on the host, or any other machines on or outside the host’s network. To configure networks, we use the $ docker network command that provides us subcommands such as lscreateattach to configure networks and containers’ relationship to them.

When you install Docker for the first time, we get three types of networks out of the box. You can use the $ docker network ls command to see them.

What is Bitcoin Cash? - A Beginner’s Guide

Bitcoin Cash was created as a result of a hard fork in the Bitcoin network. The Bitcoin Cash network supports a larger block size than Bitcoin (currently 32mb as opposed to Bitcoin’s 1mb).

Later on, Bitcoin Cash forked into Bitcoin SV due to differences in how to carry on its developments.

That’s Bitcoin Cash in a nutshell. If you want a more detailed review watch the complete video. Here’s what I’ll cover:

0:50 - Bitcoin forks
2:06 - Bitcoin’s block size debate
3:35 - Big blocks camp
4:26 - Small blocks camp
5:16 - Small blocks vs. big blocks arguments
7:05 - How decisions are made in the Bitcoin network
10:14 - Block size debate resolution
11:06 - Bitcoin cash intro
11:28 - BTC vs. BCH
12:13 - Bitcoin Cash (ABC) vs. Bitcoin SV
13:09 - Conclusion

Docker Explained: Docker Architecture | Docker Registries

Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub

In this video lesson you will learn:

  • What is Docker Host
  • What is Docker Engine
  • Learn about Docker Architecture
  • Learn about Docker client and Docker Daemon
  • Docker Hub and Registries
  • Simple demo to understand using images from registries

Docker Bridge Network

Hello readers,

This blog will tell you about the docker bridge network. Its use with some basic use cases also how to bridge networks different from the network.

One of the reasons Docker containers and services are so powerful is that you can connect them together, or connect them to non-Docker workloads.

Docker Network

Docker’s networking subsystem is pluggable, using drivers. Several drivers exist by default, and provide core networking functionality:

Type of docker Network :
  • bridge: The default network driver. If you don’t specify a driver, this is the type of network you are creating. Bridge networks allow your applications to run in standalone containers that need to communicate.
  • host: For standalone containers, remove network isolation between the container and the Docker host, and use the host’s networking directly. The host is available for swarm services on Docker 17.06 and higher.
  • overlay: Overlay networks connect multiple Docker daemons together and enable swarm services to communicate with each other. You can also use overlay networks to facilitate communication between a swarm service and a standalone container, or between two standalone containers on different Docker daemons.
  • macvlan: Macvlan networks allow you to assign a MAC address to a container, making it appear as a physical device on your network. The Docker daemon routes traffic to containers by their MAC addresses.
  • none: For this container, disable all networking. Usually used in conjunction with a custom network driver.

Let create a bridge network with name alpine-net . Start two alpine container and ping between them to check network connectivity.

$ docker network create --driver bridge alpine-net
