The Cisco Intersight Terraform Provider is available in the Terraform Registry at https://registry.terraform.io/providers/CiscoDevNet/intersight/latest. This repository contains example modules that use the provider to create
A terraform module to create a managed Kubernetes clusters using Intersight Kubernetes Service (IKS). Available through the Terraform registry.
and its source code.
- You want to create an IKS cluster on your on-premises infrastructure using Intersight.
- These resources will be provided using Intersight and VMware vCenter 6.7.
- You've claimed vCenter using the Intersight Assist Appliance.
This module creates all of the resources required for IKS. Those resources are identitified below. It is designed as a quickstart/example of how to get an IKS cluster running. More customization is being enabled but currently there are some caveats:
- Re-using IP Pools is not available in this module yet. *this is a work in progress
- Currently 3 "t-shirt" sizes are built
- Small - 4vcpu, 16GB Memory, 40GB Disk
- Medium - 8vcpu, 24GB Memory, 60GB Disk
- Large - 12vcpu, 32GB Memory, 80GB Disk
- 2 DNS and 2 NTP servers are required. If you do not have 2, list the single DNS and NTP server twice.
- The addons module does not currently function.
See the Examples ---> Complete directory for usage of this module.
