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

Docker Networking(Bridge-Network)

In this blog we gone see how two containers can communicate with each other using the concept of Docker Networking. One of the most important thing that docker.

Ever Wondered Why We Use Containers In DevOps?

At some point we've all said the words, "But it works on my machine." It usually happens during testing or when you're trying to get a new project set up. Sometimes it happens when you pull down changes from an updated branch.

Docker manifest - A peek into image's manifest.json files

The docker manifest command does not work independently to perform any action. In order to work with the docker manifest or manifest list, we use sub-commands along with it. This manifest sub-command can enable us to interact with the image manifests. Furthermore, it also gives information about the OS and the architecture, that a particular image was built for. The image manifest provides a configuration and a set of layers for a container image. This is an experimenta

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.

How to Extend your DevOps Strategy For Success in the Cloud?

DevOps and Cloud computing are joined at the hip, now that fact is well appreciated by the organizations that engaged in SaaS cloud and developed applications in the Cloud. During the COVID crisis period, most of the organizations have started using cloud computing services and implementing a cloud-first strategy to establish their remote operations. Similarly, the extended DevOps strategy will make the development process more agile with automated test cases.
