Stack > Create a Confluent Cloud Cluster.

Example: Confluent Terraform Provider with Terraform CDK

Requires Go 1.16+ and Terraform 0.15+

• Install Terraform CDK: brew install cdktf

• Clone this repo.

• Add the Confluent Provider

cdktf provider add confluentinc/confluent

Checking whether pre-built provider exists for the following constraints:
  provider: confluentinc/confluent
  version : latest
  language: go
  cdktf   : 0.15.2

Pre-built provider does not exist for the given constraints.
Adding local provider registry.terraform.io/confluentinc/confluent with version constraint undefined to cdktf.json
Local providers have been updated. Running cdktf get to update...
Generated go constructs in the output directory: generated

The generated code depends on jsii-runtime-go. If you haven't yet installed it, you can run go mod tidy to automatically install it.

Configure the Confluent Provider, provide Confluent Cloud credentials

Using tfvars file: sample.tfvars

confluent_cloud_api_key="CONFLUENT_CLOUD_API_KEY" 

confluent_cloud_api_secret="CONFLUENT_CLOUD_API_SECRET"

Deploy: cdktf deploy --var-file=./sample.tfvars

Alternatives:

• Define environment variables: TF_VAR_imageId=ami-abcde123
• --var CLI option: cdktf deploy --var='imageId=ami-abcde123'
• --var-file CLI option: cdktf deploy --var-file=/path/to/variables.tfvars

Deploys all stacks & auto approve: cdktf deploy --auto-approve '*'

Destroy cdktf destroy

Create a config.yaml file with the following options:

environment:  #confluent cloud environment id
# new cluster configuration
cluster: 
  cloud: # GCP, AWS or Azure
  region: # cloud region
  display_name: # cluster name
  availability: # SINGLE_ZONE or MULTI_ZONE - basic are SINGLE_ZONE only. 
  type: # basic, standard or dedicated
  cku: # optional: for dedicated clusters, default = 1
  serviceAccount: # optional: create a cluster API_KEY for the given service account name.

Mirror a source Confluent Cloud cluster with Cluster Link

environment: #confluent cloud environment id
# new cluster configuration
cluster: 
  cloud: # GCP, AWS or Azure
  region: # cloud region
  display_name: # cluster name 
  serviceAccount: # optional: create a cluster API_KEY for the SACC.
  # when using source mirror, destination is a dedicated cluster
  link:
    source: # source cluster id 
    key: # source cluster api key 
    secret: # source cluster api secret

• Destroy Cluster Link:

Promote mirrors:

confluent kafka mirror promote <topic_1> <topic_2> ... <topic_n> --link <link_name> --cluster <cluster_id>

• Create Terraform CDK - Golang project

cdktf init --template=go --local
