What Is Container Networking

Each container has a virtual network adapter vnic which is connected to a hyper v virtual switch vswitch.

What is container networking. To date container networking has largely been focused on simple network services like connectivity ip addressing ipam domain name services and load balancing. Hns creates a hyper v virtual switch for each network. Windows supports five different networking drivers or modes which can be created through docker. Endpoints join exactly one network and multiple endpoints can exist within a single.

Docker takes care of the networking aspects so that the containers can communicate with other containers and also with the docker host. A container is an isolated execution environment on a linux host that behaves much like a full featured linux installation with its own users file system processes and network stack. A network interface that typically comes in pairs one end of the pair sits in the network sandbox while the other sits in a designated network. 4 minutes the type of network a container uses whether it is a bridge an overlay a macvlan network or a custom network plugin is transparent from within the container from the container s point of view it has a network interface with an ip address a gateway a routing table dns services and other networking details assuming the container.

Hns creates nat and ip pools as required. Hns creates network namespace per container endpoint. Benefits such as sharing localhost communication and sharing the same ip address are inherent to the notion that containers run in the same pod which is the behavior of rkt containers. Container networking is a method of virtualization that separates out applications into independent boxes.

Essentially the networking stack within a container it is an isolated environment to contain a container s network configuration. What is container networking. Windows containers function similarly to virtual machines in regards to networking. Container networking estimated reading time.

Container networking is an emerging application sandboxing mechanism used in home desktops and web scale enterprise networking solutions similar in concept to a virtual machine isolated inside the container from the host and all other containers are a full featured linux environment with its own users file system processes and network stack. If you do an ifconfig on the docker host you will see the docker ethernet adapter. This adapter is created when docker is installed on the docker host. The host networking service hns and the host compute service hcs work together to create containers and attach endpoints to a network.
