What are various Network Drivers in it?Р”Вocker supports various network drivers that make networking easier. With this basic knowledge, we will now move ahead with the types of network drivers supported in it. A sandbox can have more than one endpoint attached to various networks.

Sandbox: A sandbox is created when a request to create an endpoint on a network is put by the user.

An endpoint has a global scope and is a service and not a container.

Endpoint: Endpoint provides/ offers the connectivity for services exposed by the one container of the network with other services provided by other containers.

#Docker network connect driver#

The corresponding driver is notified whenever the network is updated or newly created.

Network: Network provides connectivity between the endpoints of the same network and isolates them from the rest.

Driver owns the network, and there can be multiple drivers that participate in networking to fulfill various deployment and use-case scenarios.

Driver: The driver is responsible for managing the network.

Network Controller:Р’В The network controller exposes simple APIS for Docker Engine that allocates and manages networks.

The above diagram also shows 5 main objects of CNM.

Network plugin APIs are used for creating/deleting networks and adding/removing containers from the network. The IPAM plugin APIS can create/delete address pools and allocate/deallocate container IP addresses to add or remove containers from the network. CNM stores the network configuration in a distributed key-value store such as a console.Р”Р„s seen from the above diagram, CNM has interfaces for IPAM and network plugins. The CNM standardizes the steps required to provide this networking. Let's understand the details of this in the following section: What is a Container Network Model (CNM)?Р”В¬ontainer Network Model ( CNM) uses multiple network drivers to provide networking for containers. We have a model named ' Container Network Model (CNM)', which supports all the above features.

Support РІР‚вЂњ Docker offers out-of-the-box support, and its functionality is easy and straightforward, making docker networks easy to use.

User РІР‚вЂњ Friendly РІР‚вЂњ Deployment of services is easier.

So in case any container or host is missing from the pool of resources, we can pass over its services to the other resources available or bring in a new resource. Hence it enables the applications to be highly available and spread.

Decentralized РІР‚вЂњ Docker network is decentralized.

Scalability РІР‚вЂњ Being a fully distributed network, applications can scale and grow individually while also ensuring performance.

Cross-Platform РІР‚вЂњ We can use Docker Swarm clusters and use Docker in cross-platform that works across various servers.

Flexibility РІР‚вЂњ It provides flexibility for various applications on different platforms to communicate with each other.

It can be defined as a communication package that allows isolated Docker containers to communicate with one another to perform required actions or tasks.Р”Р„ Docker Network typically has features or goals shown below: Updating containers in the Docker Compose network.

How to connect the docker container to the network?.

Inspect a Docker network - docker network inspect.

What are various Network Drivers in it?.

And, what is a Container Network Model (CNM)?.

Let us begin with the topics that are going to be covered in this article.

This article will discuss more on the connection between containers and services. It is called Docker Networking, and as far as this networking is concerned, Docker containers and services need not know that they are deployed on Docker or whether the peers they are connected to are Docker workloads or not. Most of us are aware that Docker containers and services can connect and other non-Docker workloads.
