Flannel github

This plugin is designed to work in conjunction with flannel , a network fabric for containers. This information reflects the attributes of flannel network on the host. Run go mod vendor and then make. As can be seen from above, the flannel plugin, by default, will delegate to the bridge plugin. If additional configuration values need to be passed to the bridge plugin, it can be done so via the delegate field:. This supplies a configuration parameter to the bridge plugin -- the created bridge will now be named mynet0. Notice that mtu has also been specified and this value will not be overwritten by flannel plugin. Additionally, the delegate field can be used to select a different kind of plugin altogether. To use ipvlan instead of bridge , the following configuration can be specified:. The ipam part of the network configuration generated for the delegated plugin, can also be customized by adding a base ipam section to the input flannel network configuration. This ipam element is then updated with the flannel subnet, a route to the flannel network and, unless provided, an ipam type set to host-local before being provided to the delegated plugin.

In the previous article , we introduced etcd and provided a brief overview of it. These articles are part of our Kubernetes Journey. I hope you are excited to dive deep into how to install and configure Kubernetes out of the cloud! Before we talk about flannel and how it fits here it is important to understand the network characteristics of a cluster. In this section, we will focus primarily on understanding how Pod-to-Pod communication works. There are a few basic assumptions that the Kubernetes Network Model follows.

Flannel runs a small, single binary agent called flanneld on each host, and is responsible for allocating a subnet lease to each host out of a larger, preconfigured address space. Flannel uses either the Kubernetes API or etcd directly to store the network configuration, the allocated subnets, and any auxiliary data such as the host's public IP. Packets are forwarded using one of several backend mechanisms including VXLAN and various cloud integrations. Platforms like Kubernetes assume that each container pod has a unique, routable IP inside the cluster. The advantage of this model is that it removes the port mapping complexities that come from sharing a single host IP. Flannel is responsible for providing a layer 3 IPv4 network between multiple nodes in a cluster. Flannel does not control how containers are networked to the host, only how the traffic is transported between hosts. Flannel is focused on networking. For network policy, other projects such as Calico can be used. The easiest way to deploy flannel with Kubernetes is to use one of several deployment tools and distributions that network clusters with flannel by default.
