K8S CNI |

03-11-2021 |
[[Kubernetes]] implements CNI(Container Network Interface) to allow third-party networking solutions to integrate with it.
Each CNI solution needs to implement a set of things including, but not limited to:
- creating bridge networks
- attaching containers to them
- assigning IP addresses to containers
- port forwarding
Kubernetes comes with a set of CNI plugins supported by default (BRIDGE, VLAN, IPVLAN, MACVLAN, WINDOWS). In addition to this, there are third-party plugins like Flannel, WeaveWorks and Cilium.
[[Docker Networking]] does not support CNI standard, so when Docker is used in kubernetes, containers must be created with --network none option in order to let the CNI plugin manage network for them.
