I’m writing Terraform scripts for OCI (Oracle Cloud Infrastructure) Resource Manager.

I want to:

1. provision a VCN (Virtual Cloud Network) in a compartment,
2. provision public and private subnets on the VCN,
3. provision a bastion on the public subnet targeting the private subnet,
4. provision a security list for the private subnets to allow access from the bastion and
5. update the private subnet to add the security list.

Is it possible to acheive these sequently and automatically? It looks like cyclic or recursive, so I don’t know how to make these possible in Terraform.
