# Installing Kuadrant Service Protection into an existing OCM Managed Cluster

## Introduction
This walkthrough will show you how to install and setup the Kuadrant Operator into an [OCM](https://open-cluster-management.io/) [Managed Cluster](https://open-cluster-management.io/concepts/managedcluster/).

## Prerequisites
* Access to an Open Cluster Management (>= v0.11.0) Managed Cluster, which has already been bootstrapped and registered with a hub cluster
* We have [a guide](./kuadrant-hub-install.md) which covers this in detail
* Also see:
* https://open-cluster-management.io/getting-started/quick-start/
* https://open-cluster-management.io/concepts/managedcluster/
* OLM will need to be installed into the ManagedCluster where you want to run the Kuadrant Service Protection components
* See https://olm.operatorframework.io/docs/getting-started/
* Kuadrant uses Istio as a Gateway API provider - this will need to be installed into the data plane clusters
* We recommend installing Istio 1.17.0, including Gateway API v0.6.2
* ```bash
# On the Hub cluster:
kubectl get crd gateways.gateway.networking.k8s.io &> /dev/null || \
{ kubectl kustomize "github.com/kubernetes-sigs/gateway-api/config/crd?ref=v0.6.2" | kubectl apply -f -; }
```
* See also: https://istio.io/v1.17/blog/2022/getting-started-gtwapi/


Alternatively, if you'd like to quickly get started locally, without having to worry to much about the pre-requisites, take a look our [Quickstart Guide](./ocm-control-plane-walkthrough.md). It will get you setup with Kind, OLM, OCM & Kuadrant in a few short steps.
## Install the Kuadrant OCM Add-On
**Note:** if you've run our [Quickstart Guide](./ocm-control-plane-walkthrough.md), you'll be set to run this command as-is.
To install the Kuadrant Service Protection components into a `ManagedCluster`, target your OCM hub cluster with `kubectl` and run:
`kubectl apply -k "github.com/kuadrant/multicluster-gateway-controller.git/config/service-protection-install-guide" -n <your-managed-cluster>`
The above command will install the `ManagedClusterAddOn` resource needed to install the Kuadrant addon into the specified namespace, and install the Kuadrant data-plane components into the `open-cluster-management-agent-addon` namespace.
The Kuadrant addon will install:
* the Kuadrant Operator
* Limitador (and its associated operator)
* Authorino (and its associated operator)
For more details, see the Kuadrant components installed by the (kuadrant-operator)[https://github.com/Kuadrant/kuadrant-operator#kuadrant-components]
### Existing Istio installations and changing the default Istio Operator name
In the case where you have an existing Istio installation to a cluster you may encounter an issue where the Kuadrant Operator expects Istio's Operator to be named `istiocontrolplane`.

The `istioctl` command saves the IstioOperator CR that was used to install Istio in a copy of the CR named `installed-state`.

To let the Kuadrant operator use this existing installation, set the following:

`kubectl annotate managedclusteraddon kuadrant-addon "addon.open-cluster-management.io/values"='{"IstioOperator":"installed-state"}' -n <managed spoke cluster>`

This will propogate down and update the Kuadrant Operator, used by the Kuadrant OCM Addon.

## Verify the Kuadrant addon installation

To verify the Kuadrant OCM addon has installed currently, run:

```bash
kubectl wait --timeout=5m -n kuadrant-system deployment/authorino-operator deployment/kuadrant-operator-controller-manager deployment/limitador-operator-controller-manager --for=condition=Available
```

You should see the namespace `kuadrant-system`, and the following pods come up:
* authorino-*value*
* authorino-operator-*value*
* kuadrant-operator-controller-manager-*value*
* limitador-*value*
* limitador-operator-controller-manager-*value*

# Further Reading
With the Kuadrant data plane components installed, here is some further reading material to help you utilise Authorino and Limitador:
