Deploying a NiFi Registry instance (internet)

Learn about deploying a NiFi Registry cluster using Cloudera Flow Management Operator for Kubernetes.

You can deploy a NiFi Registry cluster by creating a NiFi Registry custom resource (CR) and deploying in a Kubernetes cluster.

Ensure the Cloudera Flow Management Operator for Kubernetes has been installed and is running.
You have created a NiFi Registry custom resource (CR) YAML file that complies with the documentation provided by Cloudera.

Create a namespace for the NiFi Registry if it does not already exist.
```
$ kubectl create namespace my-nifi-registry
```
In [***REGISTRY CLUSTER NAMESPACE***], create an image pull secret to access the installation artifacts.
```
kubectl create secret docker-registry [***SECRET NAME***] \
  --namespace [***REGISTRY CLUSTER NAMESPACE***] \
  --docker-server container.repository.cloudera.com \
  --docker-username [***USERNAME***] \
  --docker-password [***PASSWORD***]
```
Replace:
- [***SECRET NAME***] with the desired Kubernetes secret name.
- [***REGISTRY CLUSTER NAMESPACE***] with the namespace you created.
- [***USERNAME***] and [***PASSWORD***] with your Cloudera credentials.
For example:
```
kubectl create secret docker-registry docker-pull-secret \
  --namespace cfm-operator-system \
  --docker-server container.repository.cloudera.com \
  --docker-username my-username \
  --docker-password my-password
```
Deploy NiFi Registry to the Kubernetes cluster.
```
kubectl apply -f [***CR YAML PATH***] --namespace [***REGISTRY CLUSTER NAMESPACE***]
```
Replace:
- [***CR YAML PATH***] with the absolute or relative path to the CR YAML file you created for NiFi Registry.
- [***REGISTRY CLUSTER NAMESPACE***] with the namespace you created to deploy NiFi Registry.
