Creating a VPC using a terraform in IBM Cloud
In the previous blog, we saw how to create a resource group using terraform. Please refer it for any basic configurations needed to setup terraform on IBM Cloud
Introduction
In this blog, we are looking at creating a vpc on IBM Cloud using terraform in a Multi Zone Region(MZR). A virtual private cloud (VPC) is a secure, isolated virtual network that combines the security of a private cloud with the availability and scalability of IBM’s public cloud.VPC gives your applications logical isolation from other networks, while providing scalability and security. To make this logical isolation possible, the VPC is divided into subnets that use a range of private IP addresses. You can create subnets in suggested prefix ranges, or bring your own public IP address range (BYOIP) to your IBM Cloud account. By default, all resources within the same VPC can communicate with each other over the private network, regardless of their subnet.
Building IaC
In a new folder, let us create
you can use the Github link to download all the require files
We tried to segregate and leverage some of the best practices in creating the terraform files. Change the cloud API key in terraform.tfvars.
Prerequites:
In this demo, i have created the resources using the resource group terraform. You can create a new resource group called terraform in your IBM Cloud account or you can edit the resource group of your choice in the projectvariables.tf file
Steps to create:
Launch the terminal in the folder created. Run
terraform init
terraform plan
terraform apply
in the terminal. Once its successfully executed you will see the VPC created in your IBM Cloud Account. In this example we are creating a VPC using the default address prefix and adding subnets in each zones.
Incase you want to delete all the resources you just created, you can easily do it using
terraform destroy
in your terminal.
Thats all folks, hope this is helpful.
