# Google Cloud VMWare Engine Private Cloud Module

The module manages one or more Google Cloud VMWare Engine Private Clouds.

It also optionally creates:
- A VMWare engine network, shared betwee or it can work with an existing one. The module optionally creates peering connections to users' VPCs or other VMware engine networks.

To understand the limits and to properly configure the vSphere/vSAN subnets CIDR range please refer to the [GCVE public documentation](https://cloud.google.com/vmware-engine/docs/quickstart-networking-requirements).

Be aware that the deployment of this module might require up to 2 hours depending on the selected private cloud target zone.

## Limitations

At the moment this module doesn't support the creation of stretched private clouds.

## Basic Private Cloud Creation

```hcl
module "gcve-pc" {
  source     = "./fabric/modules/gcve-private-cloud"
  prefix     = "gcve-pc"
  project_id = "gcve-test-project"

  vmw_network_peerings = {
    transit-conn1 = {
      name         = "to-my-vpc"
      peer_network = "projects/test-prj-gcve-01/global/networks/default"
    }
  }

  vmw_private_cloud_configs = {
    pcc_one = {
      cidr = "192.168.0.0/24"
      zone = "europe-west8-a"
    }
  }
}
# tftest modules=1 resources=3 inventory=basic.yaml
```

## Customize management cluster configs

You can customize the management cluster of each VMware engine private cloud.

```hcl
module "gcve-pc" {
  source     = "./fabric/modules/gcve-private-cloud"
  prefix     = "gcve-pc"
  project_id = "gcve-test-project"

  vmw_network_peerings = {
    transit-conn1 = {
      name         = "to-my-vpc"
      peer_network = "projects/test-prj-gcve-01/global/networks/default"
    }
  }

  vmw_private_cloud_configs = {
    pcc_one = {
      cidr = "192.168.0.0/24"
      management_cluster_config = {
        node_type_id      = "standard-72"
        node_count        = 6
        custom_core_count = 28
      }
      zone = "europe-west8-a"
    }
  }
}
# tftest modules=1 resources=3 inventory=custom-management.yaml
```

## Create additional clusters

You can optionally create additional clusters in each VMware engine private cloud.

```hcl
module "gcve-pc" {
  source     = "./fabric/modules/gcve-private-cloud"
  prefix     = "gcve-pc"
  project_id = "gcve-test-project"

  vmw_network_peerings = {
    transit-conn1 = {
      name         = "to-my-vpc"
      peer_network = "projects/test-prj-gcve-01/global/networks/default"
    }
  }

  vmw_private_cloud_configs = {
    pcc_one = {
      cidr = "192.168.0.0/24"
      additional_cluster_configs = {
        test-cluster-one = {
          node_type_id      = "standard-72"
          node_count        = 6
          custom_core_count = 28
        }
        test-cluster-two = {
          node_type_id      = "standard-72"
          node_count        = 4
          custom_core_count = 28
        }
      }
      zone = "europe-west8-a"
    }
  }
}
# tftest modules=1 resources=5 inventory=additional-clusters.yaml
```
