Terraform Modules for CDP Prerequisites

This module contains resource files and example variable definition files for creation of the pre-requisite Cloud resources on AWS and optional deployment of Cloudera Data Platform (CDP) Public Cloud.

Usage

The examples directory has example AWS Cloud Service Provider deployments for different scenarios:

• ex01-minimal-inputs uses the minimum set of inputs for the module.

• ex02-existing-vpc creates a VPC and subnets outside of the module and passes this as an additional input. CDP deployment then uses these network assets.

• ex03-create-keypair creates the AWS EC2 Keypair in the module caller and passes this as an additional input.

• TODO: ex04-all_inputs_specified contains an example with all input parameters for the module.

In each directory an example terraform.tfvars.sample values file is included to show input variable values.

Deployment

Create infrastructure

1. Clone this repository using the following commands:

git clone https://github.com/cloudera-labs/terraform-cdp-modules.git
cd terraform-cdp-modules

2. Choose one of the deployment types in the examples directory and change to this directory.

cd examples/ex<deployment_type>/

3. Create a terraform.tfvars file with variable definitions to run the module. Reference the terraform.tfvars.sample file in each example folder to create this file.

4. Run the Terraform module for the chosen deployment type:

terraform init
terraform apply

Once the deployment completes, you can create CDP Data Hubs and Data Services from the CDP Management Console (https://cdp.cloudera.com/).

Clean up the infrastructure

If you no longer need the infrastructure that’s provisioned by the Terraform module, run the following command to remove the deployment infrastructure and terminate all resources.

terraform destroy

External dependencies

The module includes the option to discover the cross account Ids and to run the CDP deployment using external tools.

To utilize these options extra requirements are needed - Python 3, Ansible 2.12, the CDP CLI, the jq utility and a number of support Python libraries and Ansible collections.

A summary of the install and configuration steps for these additional requirements is given below. We recommend these steps be performed within an Python virtual environment.

# Install jq as per instructions at https://stedolan.github.io/jq/download/
# Example for MacOS using homebew shown below
brew install jq

# Install the Ansible core Python package
pip install ansible-core==2.12.10 jmespath==1.0.1

# Install cdpy, a Pythonic wrapper for Cloudera CDP CLI. This in turn installs the CDP CLI.
pip install git+https://github.com/cloudera-labs/cdpy@main#egg=cdpy

# Install the cloudera.cloud Ansible Collection
ansible-galaxy collection install git+https://github.com/cloudera-labs/cloudera.cloud.git

# Install the community.general Ansible Collection
ansible-galaxy collection install community.general:==5.5.0

# Configure cdp with CDP API access key ID and private key
cdp configure

NOTE - See the CDP documentation for steps to Generate the API access key required in the cdp configure command above.
