Automating Cloud Infrastructure Management with OCI Resource Manager

Setting Up OCI Resource Manager

Creating a Stack:

• Log in to the OCI Console.
• Navigate to Resource Manager → Stacks → Create Stack.
• Upload your Terraform configuration file.

Example Terraform Configuration:

provider "oci" {
  region = "us-ashburn-1"
}

resource "oci_core_instance" "my_instance" {
  availability_domain = "AD-1"
  compartment_id = "<compartment_OCID>"
  shape = "VM.Standard2.1"
  display_name = "MyInstance"
  image_id = "<image_OCID>"
  subnet_id = "<subnet_OCID>"

  source_details {
    source_type = "image"
    image_id = "<image_OCID>"
  }

  metadata = {
    ssh_authorized_keys = file("~/.ssh/id_rsa.pub")
  }
}

Deploying Infrastructure with Resource Manager

Creating a Job:

oci resource-manager stack create-job --stack-id <stack_OCID> --display-name "MyDeploymentJob" --operation-type APPLY

Monitoring Deployment:

oci resource-manager job list --stack-id <stack_OCID>

Managing and Updating Infrastructure

• Updating a Stack:
  • Modify the Terraform configuration file.
  • Navigate to Resource Manager → Stacks → Update Stack.
  • Upload the updated Terraform configuration file and apply changes.

Destroying Infrastructure:

oci resource-manager stack create-job --stack-id <stack_OCID> --display-name "DestroyJob" --operation-type DESTROY

Integrating with CI/CD Pipelines

Example Integration with GitHub Actions:

name: Deploy to OCI

on:
  push:
    branches:
      - main

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Set up Terraform
        uses: hashicorp/setup-terraform@v1

      - name: Terraform Init
        run: terraform init

      - name: Terraform Apply
        run: terraform apply -auto-approve
        env:
          OCI_REGION: ${{ secrets.OCI_REGION }}
          OCI_TENANCY_OCID: ${{ secrets.OCI_TENANCY_OCID }}
          OCI_USER_OCID: ${{ secrets.OCI_USER_OCID }}
          OCI_FINGERPRINT: ${{ secrets.OCI_FINGERPRINT }}
          OCI_PRIVATE_KEY_PATH: ${{ secrets.OCI_PRIVATE_KEY_PATH }}
          OCI_PRIVATE_KEY_PASSPHRASE: ${{ secrets.OCI_PRIVATE_KEY_PASSPHRASE }}
