Installation

On this page you will install the Stackable Operator for Apache NiFi and operators for its dependencies - ZooKeeper - as well as the commons and secret operator which are required by all Stackable Operators.

Stackable Operators

There are two ways to install Stackable Operators:

  1. Using stackablectl

  2. Using Helm

stackablectl

The stackablectl command line tool is the recommended way to interact with operators and dependencies. Follow the installation steps for your platform if you choose to work with stackablectl.

After you have installed stackablectl and have a Kubernetes cluster up and running, run the following command to install all operators necessary for NiFi:

stackablectl operator install \
  commons=23.7.0 \
  secret=23.7.0 \
  zookeeper=23.7.0 \
  nifi=23.7.0

The output should contain the following lines

[INFO ] Installing commons operator in version 23.7.0
[INFO ] Installing secret operator in version 23.7.0
[INFO ] Installing zookeeper operator in version 23.7.0
[INFO ] Installing nifi operator in version 23.7.0
Consult the Quickstart to learn more about how to use stackablectl.

Helm

You can also use Helm to install the operators. Add the Stackable Helm repository:

helm repo add stackable-stable https://repo.stackable.tech/repository/helm-stable/

Then install the Stackable Operators:

helm install --wait commons-operator stackable-stable/commons-operator --version 23.7.0
helm install --wait secret-operator stackable-stable/secret-operator --version 23.7.0
helm install --wait zookeeper-operator stackable-stable/zookeeper-operator --version 23.7.0
helm install --wait nifi-operator stackable-stable/nifi-operator --version 23.7.0

Helm will deploy the operators in a Kubernetes Deployment and apply the CRDs for the Apache NiFi service (as well as the CRDs for the required operators). You are now ready to deploy Apache NiFi in Kubernetes.
