Deploying a NiFi instance in Kubernetes

With CFM Operator you can deploy NiFi clusters to your Kubernetes cluster.

You can deploy a NiFi cluster by creating a NiFi custom resource (CR) and deploying it to the Kubernetes cluster.

Ensure the CFM Operator has been installed and is running.
You have created a NiFi CR YAML file that complies with the documentation provided by Cloudera.

Create the NiFi cluster namespace if it does not already exist.
```
kubectl create namespace [***NIFI CLUSTER NAMESPACE***]
```
Replace [***NIFI CLUSTER 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 CR to the Kubernetes cluster.
```
kubectl apply -f [***NIFI YAML PATH***] \
--namespace [***NIFI CLUSTER NAMESPACE***]
```
Replace
- [***NIFI YAML PATH***] with the absolute or relative path to the NiFi yaml.
- [***NIFI CLUSTER NAMESPACE***] with your desired namespace.
