• Go to DigitalOcean Console → Networking → VPC
• Click on Create VPC

Basic VPC Information

• Select Region: Example → Bangalore (blr1)

• VPC Name: red5pro-autoscaling-blr1

  Use region name as suffix for clarity. Example: <VPC_NAME>-<REGION>

• Description: (Optional) Add a description for your VPC

Configure VPC Private Subnet

• Subnet Label: red5pro-autoscaling-subnet.

• IPv4 CIDR block: 10.1.0.0/24.

  • If want to create multiple subnets, click on Add Another Subnet and specify CIDR and label.

• Click Create VPC

Example:

Record your VPC name and region — these values will be used in API calls and Terraform variables (NODE_VPC_NAME, NODE_DIGITALOCEAN_REGION) when creating node groups.

Create Firewalls
