Deploying a NiFi Registry instance (internet)

Learn about deploying a NiFi Registry cluster using CFM Operator.

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

Ensure the CFM Operator 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 the NiFi Registry cluster namespace if it does not already exist.
```
kubectl create namespace [***REGISTRY NAMESPACE***]
```
Replace [***REGISTRY NAMESPACE***] with your desired namespace.

Create an image pull secret.

kubectl create secret docker-registry docker-pull-secret \
  --namespace [***CFM OPERATOR NAMESPACE***] \
  --docker-server container.repository.cloudera.com \
  --docker-username [***USERNAME***] \
  --docker-password [***PASSWORD***]

Replace:

[***USERNAME***] and [***PASSWORD***] with your Cloudera credentials.
[***CFM OPERATOR NAMESPACE***] with the desired operator installation namespace, typically cfm-operator-system.

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

Apply your NiFi Registry CR to the Kubernetes cluster.
```
kubectl apply -f [***REGISTRY YAML PATH***] --namespace [***REGISTRY NAMESPACE***]
```
Replace:
- [***REGISTRY YAML PATH***] with the absolute or relative path to the NiFi Registry CR YAML file.
- [***REGISTRY NAMESPACE***] with your desired namespace.
