8. If you're using Kubernetes you have to use pods to organize containers and services to network them. Like the experiment with Host Mode with two containers running on same port with different IP-Address. OpenStack is also working on orchestration of Docker containers with Nova, just as it orchestrates VMs today, Edelman said. With the overlay driver, multi-host networks are first-class citizens inside Docker without external provisioning or components. It was released to the public as open source in 2013. Docker's native networking capabilities provide two mechanisms for hooking containers together. By default docker creates three networks (bridge, host and none) as shown below out of which docker bridge (appears as docker0 on host) is the default networking type unless explicitly specified. New version launches will be announced here. also played the card by establishing the project to standardize networking known as libnetwork which implements the container network model (CNM). This pod network is established and maintained by the OpenShift SDN, which configures an overlay network using Open vSwitch (OVS). Docker was designed as the internal tool in the platform as a service company, dotCloud. At the same time Docker has built a plug-in architecture that allows more advanced Overlay Driver Network Architecture. Using host networking option during docker run command, the container can directly use the network of the host system. Hi. It takes a basic use case with shared boot, proxy, master and management node with separate worker nodes. Orchestration brings order -- and challenges -- to Docker networks.

The host has the Docker daemon and client running, as depicted in Figure 1, which enables you to interact with a Docker registry on the one hand (to pull/push Docker images), and on the other hand, allows you to start, stop, and inspect containers. In this mode, you tell Docker to reuse the networking namespace of another container. Bridge, Host and None networks are by default created for us which are using bridge, host and null drivers. The container ecosystem is constantly changing and impacting the developer landscape for the better. Docker itself provides the basic networking structures necessary for container-to-container and container-to-host communication. No Docker bridges, no NAT, just pure routing rules and iptables. The clear advantage in this architecture is that you don’t need to have extra hardware for Guest OS. 04, for Every Architecture!
