| UCP component | Description |

| k8s_install-cni_calico-node | A container that's responsible for installing the Calico CNI plugin binaries and configuration on each host. Part of the `calico-node` daemonset. Runs on all nodes. |
| k8s_POD_calico-node | "Pause" container for the Calico-node pod. By default, this container is hidden, but you can see it by running `docker ps -a`. |
| ucp-agent | Monitors the node and ensures the right UCP services are running |
| ucp-interlock-extension | Helper service that reconfigures the ucp-interlock-proxy service based on the swarm workloads that are running. |
| ucp-interlock-proxy | A service that provides load balancing and proxying for swarm workloads. Only runs when you enable Layer 7 routing. |
| ucp-dsinfo | Docker system information collection script to assist with troubleshooting |
| ucp-kubelet | The kubernetes node agent running on every node, which is responsible for running Kubernetes pods, reporting the health of the node, and monitoring resource usage |
| ucp-kube-proxy | The networking proxy running on every node, which enables pods to contact Kubernetes services and other pods, via cluster IP addresses |
| ucp-reconcile | When ucp-agent detects that the node is not running the right UCP components, it starts the ucp-reconcile container to converge the node to its desired state. It is expected for the ucp-reconcile container to remain in an exited state when the node is healthy. |
| ucp-proxy | A TLS proxy. It allows secure access to the local Docker Engine to UCP components |

## How you interact with UCP
There are two ways to interact with UCP: the web UI or the CLI.
