TF-octopus

This Terraform project deploys an Amazon Web Services (AWS) Virtual Private Cloud (VPC) with subnets in the us-west-1 region and VM resources in on-premises VMware vCenter 7.0. It's designed for streamlining entities' creation process in different environments.

Prerequisites

Before you begin, ensure you have the following prerequisites:

• Terraform installed on your local machine.
• AWS credentials configured with the necessary permissions. These credentials should be set up in your ~/.aws/credentials file.

Getting Started with AWS

1. Clone this repository to your local machine: git clone <repository-url>
2. Navigate to the project directory: cd <project-directory>
3. Initialize Terraform: terraform init
4. Review and customize the variables in the variables.tf file as needed.
5. Create a terraform.tfvars file (or use -var options with terraform apply) to provide values for your variables.
6. Apply the Terraform configuration: terraform apply
7. Confirm and apply the changes by typing "yes" when prompted.
8. Once the deployment is complete, Terraform will display the outputs, including VPC and subnet IDs.

Project Structure

The project structure is organized as follows:

• main.tf: Defines the AWS provider, variables, resources, and outputs.
• variables.tf: Declares input variables and their descriptions.
• terraform.tfvars: Provides values for variables (create this file).
• outputs.tf: Defines the output values displayed after deployment.

Variables

• cidr_blocks: A list of CIDR blocks and name tags for VPC and subnets.
• environment: Deployment environment (e.g., "dev", "prod").

Resources

• aws_vpc: Defines an AWS VPC resource with the specified CIDR block and tags.
• aws_subnet: Defines AWS subnets within the VPC.
• data.aws_vpc.existing_vpc: Retrieves information about an existing VPC.

Outputs

• vpc-id: Displays the VPC's name tag.
• subnet-1-id: Displays the name tag for subnet 1.
• subnet-2-id: Displays the name tag for subnet 2.

Getting Started with AWS EC2 instances

• To start working with this project navigate to the project directory: cd web

Getting Started with VMware vCenter

This Terraform configuration defines the provisioning of a virtual machine (VM) on a VMware vSphere infrastructure. It includes the setup of the necessary providers, data sources for datacenter, datastore, compute cluster, and network, as well as the creation of a virtual machine.

• To start working with this project navigate to the project directory: cd vmware

Configuration Variables

• username: The username for authenticating with the vCenter server.
• password: The password for authenticating with the vCenter server.
• vsphere_server: The address of the vCenter server.

Provider Configuration

The vsphere provider is configured to connect to the VMware vSphere infrastructure using the provided credentials and server address. Additionally, the allow_unverified_ssl option is set to true to allow connections to vCenter servers with self-signed SSL certificates.

Data Sources

• vsphere_datacenter: Retrieves information about the datacenter named "1iq-dc" in the vSphere infrastructure.
• vsphere_datastore: Retrieves information about the datastore named "vsanDatastore" associated with the specified datacenter.
• vsphere_compute_cluster: Retrieves information about the compute cluster named "1iq-vsan" within the specified datacenter.
• vsphere_network: Retrieves information about the network named "vLAN Lab" within the specified datacenter.

Virtual Machine Resource

The vsphere_virtual_machine resource defines the creation of a virtual machine with the following characteristics:

Name: "opensuse-15-6"
Resource pool: The resource pool associated with the specified compute cluster.
Datastore: The datastore associated with the specified datacenter.
CPU: 1 virtual CPU.
Memory: 2048 MB.
Guest ID: "other3xLinux64Guest."
Network: Connected to the "vLAN Lab" network.
Disk: One disk labeled "disk0" with a size of 16 GB.
No wait for guest network timeout.

Output

The vm_ip output provides the IP address of the VMware vSphere virtual machine. This IP address can be used to access and manage the provisioned virtual machine.

Terraform Commands

• terraform init: Initialize the Terraform project.
• terraform plan: Review the execution plan.
• terraform apply: Apply the Terraform configuration to create AWS resources.
• terraform destroy: Destroy all created resources.
• terraform output: Display the output values.
