## Introduction to calico/node

The calico/node container is deployed to every node (on Kubernetes, by a DaemonSet), and runs three daemons:

- Felix, the Calico daemon that runs on every node and provides endpoints.
- BIRD, the BGP daemon that distributes routing information to other nodes.
- confd, a daemon that watches the Calico datastore for config changes and updates BIRD’s config files.

For manifest-based installations, calico/node is primarily configured through environment variables, typically set in the deployment manifest. Individual nodes may also be updated through the Node custom resource. calico/node can also be configured through the Calico Operator.
