Terraform-Created-Resources

Terraform module for creation of resources on public cloud platforms.

The following public cloud platforms and resources are currently covered:

1. AWS - EC2 and Lightsails instances (VMs) with Node.js and MongoDB installations.
   Note 1: Node.js is installed on the the web server instance(s).
   Note 2: Node.js and MongoDB are installed on the db server instance(s).
   Note 3: Node.js installation can be disabled on the db server instance(s):
   a) By setting the variable enable_web_server, in the init_mongodb_server.sh file to false.
   b) See line 30 of init_mongodb_server.sh file.
   
2. Linode - Linode instances (VMs) with Node.js and MongoDB installations.
   Note 1: Node.js and MongoDB are installed on the web server instance(s).
   Note 2: MongoDB installation can be disabled on the web server instance(s):
   a) By setting the variable, enable_mongodb_server, to false in the startup script
   b) See line 122 of the main.tf file, where linode_stackscript_init is defined.
   

This repo is based on Terraform Version 0.14.4.

RUNNING MODULE

To run the module to create resources on AWS:

1. Save or download the start-up bash file(s) in the link(s) below to the current working directory (CWD):
   a) https://raw.githubusercontent.com/MongoExpUser/Terraform-Created-Resources/master/init_web_server.sh
   b) https://raw.githubusercontent.com/MongoExpUser/Terraform-Created-Resources/master/init_mongodb_server.sh
   

2. Also, copy the following script into a file (base.tf) in the current working directory:

# define credential variable(s) of provider(s)
variable "aws_access_key" {}
variable "aws_secret_key" {}
variable "aws_region" {}
variable "create_aws_resources" {default = 1}

# define provider(s)
provider "aws" {
  access_key = var.aws_access_key
  secret_key = var.aws_secret_key
  region     = var.aws_region
}

# create resource(s)
module "public_cloud_resources" {
  source = "git::https://github.com/MongoExpUser/Terraform-Created-Resources.git"
}

# create output(s)
output "ec2_web_server_instances" {
  description = "A list of all created EC2 web server instances"
  # the list contains key-value pairs of each instance's attributes
  value = module.public_cloud_resources.aws_ec2_web_servers
}

output "ec2_db_server_instances" {
  description = "A list of all created EC2 db server instances"
  # the list contains key-value pairs of each instance's attributes
  value = module.public_cloud_resources.aws_ec2_db_servers
}

output "lightsail_web_server_instances" {
  description = "A list of all created AWS lightsail web server instances"
  # the list contains key-value pairs of each instance's attributes
  value = module.public_cloud_resources.aws_lightsail_web_servers
}

output "lightsail_db_server_instances" {
  description = "A list of all created AWS lightsail db server instances"
  # the list contains key-value pairs of each instance's attributes
  value = module.public_cloud_resources.aws_lightsail_db_servers
}

output "lightsail_web_server_static_ips" {
  description = "A list of all created AWS lightsail static ips"
  # the list contains key-value pairs of each instance's attributes
  value = module.public_cloud_resources.aws_lightsail_web_server_static_ips
}

output "lightsail_db_server_static_ips" {
  description = "A list of all created AWS lightsail static ips"
  # the list contains key-value pairs of each instance's attributes
  value = module.public_cloud_resources.aws_lightsail_db_server_static_ips
}

3. Finally, execute the module from the base file (base.tf) in the current working directory (CWD) by typing the following commands at the prompt (assuming running via bash with sudo access):

  #1) run init
  sudo terraform init
  
  #2) run terraform plan
  sudo TF_VAR_aws_access_key="access-key-value" \
       TF_VAR_aws_secret_key="secret-key-value" \
       TF_VAR_aws_region="aws-region-value" \
       terraform plan
                                                                                    
  #3) run terraform apply
  sudo TF_VAR_aws_access_key="access-key-value" \
      TF_VAR_aws_secret_key="secret-key-value" \
      TF_VAR_aws_region="aws-region-value" \
      terraform apply

To run the module to create resources on Linode:

1. Copy the following script into a file (base.tf) in the current working directory:

# define credential variable(s) of provider(s)
variable "linode_token_value" {}
variable "create_linode_resources" {default = 1}

# define provider(s)
provider "linode" {
  token = var.linode_token_value
}

# create resource(s)
module "public_cloud_resources" {
  source = "git::https://github.com/MongoExpUser/Terraform-Created-Resources.git"
}

# create outputs
output "linode_sshkeys" {
  description = "A list of all created linode_sshkeys"
  # the list contains key-value pairs of each linode_sshkey's attributes
  value = module.public_cloud_resources.linode_sshkeys
}

output "linode_stackscripts" {
  description = "A list of all created linode_stackscripts"
  # the list contains key-value pairs of each linode_stackscript's attributes
  value =  module.public_cloud_resources.linode_stackscripts
}

output "linode_instance_web_servers" {
  description = "A list of all created linode_instances"
  # the list contains key-value pairs of each linode_instance's attributes
  value = module.public_cloud_resources.linode_instance_web_servers
}

2. Then, execute the module from the base file (base.tf) in the current working directory (CWD) by typing the following commands at the prompt (assuming running via bash with sudo access):

  #1) run init
  sudo terraform init
  
  #2) run terraform plan
  sudo TF_VAR_linode_token_value="linode-token-value" terraform plan
                                                                                    
  #3) run terraform apply
  sudo TF_VAR_linode_token_value="linode-token-value" terraform apply
