confluent-kafka-cluster

This repo contains terraform code which provisions resources in Confluent Cloud. These resources provisioned are:

  • Confluent Environment
  • Confluent Kafka Cluster
  • Confluent Kafka Topic
  • Producer and Consumer Service Accounts
  • ACL for the Producer with write permissions to topic
  • ACL for the Consumer with read permissions to topic
  • API keys for the Producer and Consumer applications to authenticate with Confluent Cloud.

These resources are defined in main.tf.

Deployment of Resources

This is just a proof of concept so there are no deployment pipelines.

Set Environment Variables

Terraform needs credentials to create resources in Confluent Cloud. Locally, we can do that by defining an API key and secret in the environment variables. These two values can be generated through the Confluent Cloud console.

export CONFLUENT_CLOUD_API_KEY=<API_KEY>
export CONFLUENT_CLOUD_API_SECRET=<API_SECRET>

Initialise Project

Initialise the Terraform project:

terraform init

Terraform Plan

Create a Terraform plan:

terraform plan -out main.tfplan

Terraform Apply

Apply the plan and deploy resources to Confluent Cloud.

terraform apply "main.tfplan"

Terraform Destroy

To de-provision the deploy resources:

Terraform destroy
