Paving

This repository contains Terraform templates for paving the necessary infrastructure to deploy Tanzu application Platform (PKS and TAS) to a single foundation. The templates support AWS, vSphere, Azure, and GCP.

Requirements

As of v3.0.0 of this repository the following are the supported versions of the Terraform CLI and providers:

• Terraform CLI v1.0.11
• Provider versions

  Provider	version
  GCP	4.1.0
  AWS	3.65.0
  Azure	2.85.0

Usage

Configuration

In each IaaS directory, there is a terraform.tfvars.example you can copy and modify with your configuration choices and credentials.

1. terraform init
2. terraform plan -var-file terraform.tfvars
3. terraform apply -var-file terraform.tfvars
4. terraform output stable_config_output
5. terraform destroy -var-file terraform.tfvars

Removing unnecessary resources

The terraform templates are namespaced for the resources that consume them. In each IAAS, the prefix opsmanager-, pks-, and pas- are on the file names.

There are cases that some resources aren't required in a foundation. For example, just deploying PKS and not PAS. To remove PAS resources, just rm pas-*.tf the file from the directory.

Please note that the opsmanager-*.tf files cannot be removed. Every foundation requires an Ops Manager.

Decisions

• These templates support deploying Tanzu Application Service (TAS) and Pivotal Container Service (PKS) to the same foundation.

• The templates do not create an Ops Manager VM but do create the necessary infrastructure for the VM (security groups, keys, etc).

• These templates demonstrate a modest production deployment in three (3) AZs on each IaaS.

• These templates contain extremely minimal interdependence or cleverness, to facilitate incorporating these templates into your own automation easily.

Versioning

The semantics of the versioning of paving's releases are based on the contents of terraform output stable_config_(opsmanager|pas|pks). stable_config should always represent the minimum necessary to install Pivotal Platform. Any other output may be added or removed without a change in version. However, MAJOR.MINOR.PATCH should change according to the following:

• If an output is removed or a major breaking change is introduced, the MAJOR version should be incremented
• If an output is added, the MINOR version should be incremented
• Otherwise, the patch version should be incremented

Customization

Jumpbox

In our current configuration, we are using the Ops Manager VM as the jumpbox. The Ops Manager VM is deployed in the public subnet with a configuration (var.ops_manager_allowed_ips) to restrict it by IP. If you want to use a jumpbox instead, you may deploy ops manager in the management subnet.
