        # Avi ALB Controller Deployment on GCP Terraform module

This Terraform module creates and configures an AVI (NSX ALB) Controller on GCP

## Module Functions

The module is meant to be modular and can create all or none of the prerequiste resources needed for the Avi GCP Deployment including:

* VPC and Subnet for the Controller (optional with create_networking variable)

* IAM Roles and Role Bindings for supplied Service Account (optional with create_iam variable)

* GCP Compute Image from the provided bucket controller file

* Firewall Rules for Avi Controller and SE communication

* GCP Compute Instance using the Controller Compute Image

During the creation of the Controller instance the following initialization steps are performed:

* Change default password to user specified password

* Copy Ansible playbook to controller using the assigned public IP

* Run Ansible playbook to configure initial settings and GCP Full Access Cloud 

Optionally the following Avi configurations can be created:

* Avi IPAM Profile (configure_ipam_profile variable)

* Avi DNS Profile (configure_dns_profile variable)

* DNS Virtual Service (configure_dns_vs variable)

# Environment Requirements

## Google Cloud Platform

The following are GCP prerequisites for running this module:

* Service Account created for the Avi Controller

* Projects identified for the Controller, Network, Service Engines, Storage, and Backend Servers. By default this be the a single project as set by the "project" variable. Optionally the "network_project", "service_engine_project", "storage_project", and "server_project" variables can be set to use a different project than the project the Controller will be deployed to. 

* If more than 1 project will be used "Disable Cross-Project Service Account Usage" organizational policy must be set to "Not enforced" and the the Service Account must be added to those additional projects. 

## Google Provider

For authenticating to GCP you must leverage either the "GOOGLE_APPLICATION_CREDENTIALS={{path_to_service_account_key}}" environment variable or use "gcloud auth application-default login"

## Controller Image

The AVI Controller image for GCP should be uploaded to a GCP Cloud Storage bucket before running this module with the path specified in the controller-image-gs-path variable. This can be done with the following gsutil commands:

```bash

gsutil mb 

gsutil -m cp ./gcp_controller-.tar.gz  gs:///

```

## Host OS 

The following packages must be installed on the host operating system:

* curl 

# Usage

```hcl

terraform {

  backend "local" {

  }

}

provider "google" {

  project = "PROJECT"

  region  = "REGION"

}

module "avi_controller_gcp" {

  source  = "vmware/avi-alb-deployment-gcp/google"

  version = "1.0.x"

  region = "us-west1"

  create_networking = "true"

  create_iam = "false"

  controller_default_password = "Value Redacted and available within the VMware Customer Portal"

  avi_version = "21.1.1"

  service_account_email = "@.iam.gserviceaccount.com"

  controller_image_gs_path = "/gcp_controller-21.1.1.tar.gz"

  controller_password = "password"

  name_prefix = "avi"

  project = "gcp-project"

}

output "controller_address" { 

  value = module.avi_controller_gcp.controllers

} 

```

## GSLB Deployment

For GSLB to be configured successfully the configure_gslb and configure_dns_vs variables must be configured. By default a new Service Engine Group (g-dns) and user (gslb-admin) will be created for the configuration. 

The following is a description of the configure_gslb variable parameters and their usage:

| Parameter   | Description | Type |

| ----------- | ----------- | ----------- |

| enabled      | Must be set to "true" for Active GSLB sites | bool

| leader      | Must be set to "true" for only one GSLB site that will be the leader | bool

| site_name   | Name of the GSLB site   | string

| domains   | List of GSLB domains that will be configured | list(string)

| create_se_group | Determines whether a g-dns SE group will be created        | bool

| se_size   | The CPU, Memory, Disk Size of the Service Engines. The default is 2 vCPU, 8 GB RAM, and a 30 GB Disk per Service Engine | string

| additional_sites   | Additional sites that will be configured. This parameter should only be set for the primary GSLB site | string

The example below shows a GSLB deployment with 2 regions utilized.

```hcl

terraform {

  backend "local" {

## Controller Sizing

The controller_size variable can be used to determine the vCPU and Memory resources allocated to the Avi Controller. There are 3 available sizes for the Controller as documented below:

| Size | vCPU Cores | Memory (GB)|

|------|-----------|--------|

| small | 8 | 24 |

| medium | 16 | 32 |

| large | 24 | 48 |

## Day 1 Ansible Configuration and Avi Resource Cleanup

The module copies and runs an Ansible play for configuring the initial day 1 Avi config. The plays listed below can be reviewed by connecting to the Avi Controller by SSH. In an HA setup the first controller will have these files. 

### avi-controller-gcp-all-in-one-play.yml

This play will configure the Avi Cloud, Network, IPAM/DNS profiles, DNS Virtual Service, GSLB depending on the variables used. The initial run of this play will output into the ansible-playbook.log file which can be reviewed to determine what tasks were ran. 

Example run (appropriate variable values should be used):

```bash

~$ ansible-playbook avi-controller-gcp-all-in-one-play.yml -e password=${var.controller_password} > ansible-playbook-run.log

```

### avi-upgrade.yml

This play will upgrade or patch the Avi Controller and SEs depending on the variables used. When ran this play will output into the ansible-playbook.log file which can be reviewed to determine what tasks were ran. This play can be ran during the initial Terraform deployment with the avi_upgrade variable as shown in the example below:

```hcl

avi_upgrade = { enabled = "true", upgrade_type = "patch", upgrade_file_uri = "URL Copied From portal.avipulse.vmware.com"}

```

An full version upgrade can be done by changing changing the upgrade_type to "system". It is recommended to run this play in a lower environment before running in a production environment and is not recommended for a GSLB setup at this time.

Example run (appropriate variable values should be used):

```bash

~$ ansible-playbook avi-upgrade.yml -e password=${var.controller_password} -e upgrade_type=${var.avi_upgrade.upgrade_type} -e upgrade_file_uri=${var.avi_upgrade.upgrade_file_uri} > ansible-playbook-run.log

```

### avi-cloud-services-registration.yml

This play will register the Controller with Avi Cloud Services. This can be done to enable centralized licensing, live security threat updates, and proactive support. When ran this play will output into the ansible-playbook.log file which can be reviewed to determine what tasks were ran. This play can be ran during the initial Terraform deployment with the register_controller variable as shown in the example below:

```hcl

register_controller = { enabled = "true", jwt_token = "TOKEN", email = "EMAIL", organization_id = "LONG_ORG_ID" }

```

The organization_id can be found as the Long Organization ID field from https://console.cloud.vmware.com/csp/gateway/portal/#/organization/info.

The jwt_token can be retrieved at https://portal.avipulse.vmware.com/portal/controller/auth/cspctrllogin.

Example run (appropriate variable values should be used):

```bash

~$ ansible-playbook avi-cloud-services-registration.yml -e password=${var.controller_password} -e register_controller.jwt_token=${var.register_controller.jwt_token} > ansible-playbook-run.log

```

### avi-cleanup.yml

This play will disable all Virtual Services, delete all existing Avi service engines, and de-register the controller from Cloud Services. This playbook should be ran before deleting the controller with terraform destroy to clean up the resources created by the Avi Controller. Note that additional items created by the controller may be created and need to be manually removed.

Example run (appropriate variable values should be used and -e register_controller.jwt_token is only needed when register_controller.enabled is set to true):

```bash

~$ ansible-playbook avi-cleanup.yml -e password=${var.controller_password} -e register_controller.jwt_token=${var.register_controller.jwt_token}

```
