## Hubble
{{ kops_feature_table(kops_added_default='1.20.1', k8s_min='1.20') }}

Hubble is the observability layer of Cilium and can be used to obtain cluster-wide visibility into the network and security layer of your Kubernetes cluster. See the [Hubble documentation](https://docs.cilium.io/en/v1.10/gettingstarted/hubble_setup/) for more information.

Hubble can be enabled by adding the following to the spec:
```yaml
networking:
cilium:
hubble:
enabled: true
```

This will enable Hubble in the Cilium agent as well as install hubble-relay. kOps will also configure mTLS between the Cilium agent and relay. Note that since the Hubble UI does not support TLS, the relay is not configured to listen on a secure port.

The Hubble UI has to be installed separatly.

## Getting help

For problems with deploying Cilium please post an issue to Github:
