Kodekloud Terraform Challenge 1 solution | Install , Configure terraform and provider settings within provider.tf | Deploy several Kubernetes resources using terraform

Question : Welcome to the terraform challenge series.

In this challenge we will deploy several Kubernetes resources using terraform.
Utilize /root/terraform_challenge directory to store your Terraform configuration files.

Inspect the requirements in detail by clicking on the icons of the interactive architecture diagram on the right and complete the tasks.

1. Terraform version: 1.1.5 installed on controlplane?

2.  Kubernetes provider : - 

  • Configure terraform and provider settings within provider.tf file with following specifications:
  • Configure terraform to use hashicorp/kubernetes provider.
  • Specify the provider's local name: kubernetes
  • Provider version: 2.11.0
  • Configure kubernetes provider with path to your kubeconfig file: /root/.kube/config

3.  Create a terraform resource webapp-service for kubernetes service with following specs:

  • Service name: webapp-service
  • Service Type: NodePort
  • Port: 8080
  • NodePort: 30080
4. Create a terraform resource frontend for kubernetes deployment with following specs:

  • Deployment Name: frontend
  • Deployment Labels = name: frontend
  • Replicas: 4
  • Pod Labels = name: webapp
  • Image: kodekloud/webapp-color:v1
  • Container name: simple-webapp
  • Container port: 8080

2. Check Terraform version and download the ZIP file and extract it

root@controlplane ~   which terraform

 root@controlplane ~   which terraform

/usr/local/bin/terraform

 root@controlplane ~   terraform --version

Terraform v1.1.5

on linux_amd64

 Your version of Terraform is out of date! The latest version

is 1.6.4. You can update by downloading from https://www.terraform.io/downloads.html

root@controlplane ~


3. Configure terraform and provider settings within the provider.tf file

root@controlplane ~   cd /root/terraform_challenge/

root@controlplane ~/terraform_challenge   ls

root@controlplane ~/terraform_challenge   vi provider.tf

 root@controlplane ~/terraform_challenge via 💠 default   cat provider.tf

terraform {

  required_providers {

    kubernetes = {

      source = "hashicorp/kubernetes"

      version = "2.11.0"

    }

  }

}

 

provider "kubernetes" {

  config_path    = "/root/.kube/config"

}

root@controlplane ~/terraform_challenge via 💠 default   terraform init

Initializing the backend...

Initializing provider plugins...

- Finding hashicorp/kubernetes versions matching "2.11.0"...

- Installing hashicorp/kubernetes v2.11.0...

- Installed hashicorp/kubernetes v2.11.0 (signed by HashiCorp)

 

Terraform has created a lock file .terraform.lock.hcl to record the provider

selections it made above. Include this file in your version control repository

so that Terraform can guarantee to make the same selections by default when

you run "terraform init" in the future.

 

Terraform has been successfully initialized!

 

You may now begin working with Terraform. Try running "terraform plan" to see

any changes that are required for your infrastructure. All Terraform commands

should now work.

If you ever set or change modules or backend configuration for Terraform,

rerun this command to reinitialize your working directory. If you forget, other

commands will detect it and remind you to do so if necessary.

root@controlplane ~/terraform_challenge via 💠 default  


4. Create terraform resources frontend  for Kubernetes deployment & webapp-services for Kubernetes services

Created  TF files with all the parameters, Kindly clone repo or you can copy from GitLab 

git clone https://gitlab.com/nb-tech-support/devops.git

 Refer Below Video for more clarity )

root@controlplane ~/terraform_challenge via 💠 default kubectl get pods -A
