Automating UCS Server Provisioning with Terraform and Intersight

Use Case Statement

The workspace 01-simple-inventory provides a very minimal Terraform configuration to simply help you get your core credentials defined, tested, and also give you some sample Terraform commands and output to help navigate your first time with Terraform and Intersight.

The workspace 02-full-profile provides a comprehensive set of server policies and server profile sufficient to configure a UCS C-series rack mount server (in standalone management mode) that is connected to Intersight as a hypervisor with ethernet, fibre channel, and local storage resources.

Pre-requisites

Clone the Repository and Deploy the Profiles

git clone https://github.com/CiscoSE/BRKDEV-2004-CL21
cd BRKDEV-2004-CL21

# For use case 1 (see README for details)
cd 01-simple-inventory
terraform init
terraform plan
terraform apply
cd ..

# For use case 2 (see README for details, variables are needed!)
cd 02-full-profile
terraform init
terraform plan
terraform apply
cd ..

Required Variables

The following environment variables are required to be set for all Terraform plans in this repository:

  • TF_VARS_intersight_apikey: The API key with administrative access to the Intersight account
  • TF_VARS_intersight_secretkey: The Secret keyfile contents for the provided API key
  • TF_VARS_c240_m4l_lab_device_id: The serial number for the C-series server being used in this demo

For the full profile Terraform plan 02-full-profile/main.tf, you'll also need to define these SNMP related security credentials:

  • TF_VAR_snmp_access_community_string: SNMP v1/v2c community string
  • TF_VAR_snmp_trap_community_string: SNMP v1/v2c trap community string

Please refer to the setup-environment-vars.txt file to show a "safe" method for storing the credentials in your local acount - "safe", of course, in this case with regards to avoiding accidental commits of your credentials to the Git repository.
