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

root@controlplane ~ ➜  which terraform root@controlplane ~ ➜  root@controlplane ~ ➜  curl -L -o /tmp/terraform_1.1.5_linux_amd64.zip https://releases.hashicorp.com/terraform/1.1.5/terraform_1.1.5_linux_amd64.zip   % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current                                  Dload  Upload   Total   Spent    Left  Speed 100 17.8M  100 17.8M    0     0  45.9M      0 --:--:-- --:--:-- --:--:-- 45.9M  root@controlplane ~ ➜  ls /tmp systemd-private-bac02dd1f6b44f1ca3c0c2e17a9e6c3b-systemd-resolved.service-GujsGO  terraform_1.1.5_linux_amd64.zip  root@controlplane ~ ➜  unzip -d /usr/local/bin /tmp/terraform_1.1.5_linux_amd64.zip Archive:  /tmp/terraform_1.1.5_linux_amd64.zip   inflating: /usr/local/bin/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 root@controlplane ~ ➜  terraform --version Terraform v1.1.5 on linux_amd64  Your version of Terraform is out of date!

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
