The host networking service hns and the host compute service hcs work together to create containers and attach endpoints to a network.
What is container networking.
If you do an ifconfig on the docker host you will see the docker ethernet adapter.
Docker takes care of the networking aspects so that the containers can communicate with other containers and also with the docker host.
Containers are similar to virtual machines though with a few key differences.
Beyond connectivity most higher level network services like quality of service qos virtual private networking security policy complex and dynamic firewalling and topology optimization are still emerging.
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.
Each container has a virtual network adapter vnic which is connected to a hyper v virtual switch vswitch.
Hns creates a hyper v virtual switch for each network.
Nat overlay transparent l2bridge and l2tunnel.
Container networking is a method of virtualization that separates out applications into independent boxes.
Container networking estimated reading time.
Essentially the networking stack within a container it is an isolated environment to contain a container s network configuration.
Hns creates nat and ip pools as required.
Windows containers function similarly to virtual machines in regards to networking.
To date container networking has largely been focused on simple network services like connectivity ip addressing ipam domain name services and load balancing.
What is container networking.
This adapter is created when docker is installed on the docker host.
Hns creates network namespace per container endpoint.
Windows supports five different networking drivers or modes which can be created through docker.
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.
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.
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.
