We are going to use the bucket to store the Apache NiFi & ZooKeeper binaries (instead of downloading directly from the Apache repositories at each deployment), and also as a way to retrieve the certificates that we’ll use for the HTTPS load balancer. In your GCP project, create a bucket in Google Cloud Storage. Download the NiFi binaries in Google Cloud Storage It protects you and your users by ensuring that OAuth authentication is only coming from authorized domains. Once the credentials are created, you will get a client ID and a client secret that you will need in the Terraform variables.īy creating the credentials, your domain will be automatically added to the list of the “Authorized domains” in the OAuth consent screen configuration. Please adapt with your own domain (note there is no port as we’ll use the load balancer to access the cluster) For Authorized JavaScript origins, use your own domain. Click on Create credentials, OAuth client ID.Go in your GCP project, APIs & Services, Credentials.Additionally, when a new node elects to join the cluster, the new node must first connect to the currently-elected Cluster Coordinator in order to obtain the most up-to-date flow.įirst step is to create the OAuth Credentials (at this moment, this cannot be done using Terraform). All nodes in the cluster will then send heartbeat/status information to this node, and this node is responsible for disconnecting nodes that do not report any heartbeat status for some amount of time. One of the nodes is automatically elected (via Apache ZooKeeper) as the Cluster Coordinator. Each node in the cluster performs the same tasks on the data, but each operates on a different set of data. As soon as you need to bring data in, you want to use Apache NiFi.īest is to refer to the documentation, but, in short… NiFi employs a Zero-Master Clustering paradigm. In simpler words, Apache NiFi is a great tool to collect and move data around, process it, clean it and integrate it with other systems. Apache NiFi supports powerful and scalable directed graphs of data routing, transformation, and system mediation logic. The infrastructure Terraform can manage includes low-level components such as compute instances, storage, and networking, as well as high-level components such as DNS entries, SaaS features, etc.Īpache NiFi is an easy to use, powerful, and reliable system to process and distribute data. As the configuration changes, Terraform is able to determine what changed and create incremental execution plans which can be applied. Terraform generates an execution plan describing what it will do to reach the desired state, and then executes it to build the described infrastructure. Terraform can manage existing and popular service providers as well as custom in-house solutions.Ĭonfiguration files describe to Terraform the components needed to run a single application or your entire datacenter. Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. If you don’t want to read the story and want to get straight into the code, it’s right here ! In this post, I use my own domain: and will map to my NiFi cluster.ĭisclaimer - the below steps should not be used for a production deployment, it can definitely get you started but I’m just using the below to start a secured cluster (there is no configuration that one would expect for a production setup such as a clustered Zookeeper, disks for repositories, etc). It will be used to map a domain to the web interface exposed by the NiFi cluster. Note - I assume you have a domain that you own ( you can get one with Google). configure an HTTPS load balancer with Client IP affinity in front of the NiFi cluster.configure NiFi to use OpenID connect for authentication.deploy X secured NiFi instances clustered together.deploy an external ZooKeeper instance to manage cluster coordination and state across the nodes.deploy a NiFi CA server as a convenient way to generate TLS certificates.In this story, we’ll use Terraform to quickly: This time it’s about deploying a secured NiFi cluster. ![]() This story is a follow up of this previous story about deploying a single secured NiFi instance, configured with OIDC, using Terraform on the Google Cloud Platform. ![]()
