vcenter.tf

# Sample terraform script to create VMs on vcenter cluster for use with Contiv
#
# To use:
# 1. Create vcenter.tfvars file with the following variables defined
# 2. Place this file (vcenter.tf) and your new vcenter.tfvars in the same
#    directory.
# 3. Test your terraform configuration:
#    $ terraform plan -var-file vcenter.tfvars
#
# 4. If no errors, bring up your terraform environment:
#    $ terraform apply -var-file vcenter.tfvars
