[SoyluAlaattin]

Description

In this task, you will install and use Terraform on the Kubesphere running on our office server. Carefully follow the steps below and make the necessary configurations.

Steps

1. Install Terraform

   • Download and install Terraform from the HashiCorp official website.
   • Verify the installation by running the command terraform --version.

2. Configure Kubernetes and Kubesphere Providers

   • Create a Terraform configuration file (main.tf).
   • Set up the Kubernetes provider and ensure the kubeconfig file is in the correct location (~/.kube/config).

3. Prepare the Kubeconfig File

   • Check the kubeconfig file to ensure access to the Kubesphere API server.
   • Create or update the kubeconfig file if necessary.

4. Namespace Labeling

   • Label the namespaces where you want Istio to automatically inject the sidecar using the command kubectl label namespace <namespace> istio-injection=enabled.

5. Create Terraform Configuration Files

   • Create Terraform configuration files that define Kubernetes resources.
   • For example, define a namespace and a deployment.

6. Follow the Terraform Workflow

   • Initialize your Terraform working directory with the command terraform init.
   • Create and review the infrastructure plan with the command terraform plan.
   • Apply the configuration with the command terraform apply.

7. Security and Permissions

   • Ensure you have the necessary permissions on Kubernetes.
   • Define and apply the required roles and role bindings (RoleBinding).

8. Monitoring and Logging

   • Use Kubernetes and Kubesphere monitoring tools to ensure the resources created by Terraform are working correctly.
   • Track and resolve any errors and performance issues that may arise.

Notes

• Follow all steps carefully and note any errors that occur at each step.
• Refer to the Terraform and Kubernetes documentation for assistance if needed.
• Upon completion of the task, prepare a detailed report of the resources created and configurations made.
