What

Simple terraform script for creating GPU VMs in a (private) subnet and a Ngninx load balancer in a (public) subnet.

Prereqs

VCN setup:

Create VCN using the wizard created VCN, accept all defaults.

Edited a few exceptions afterward.

Exception 1:

Added a Bastion service with entry point in the public subnet.

In my case this one has private IP: 10.0.0.49

Exception 2:

Edited Security List for Private Subnet-<your-vcn-name>. Removed rule that allows ssh (port 22) traffic from entire network (10.0.0.0/16) Added rule to accept SSH traffic from Bastion ip (10.0.0.49/32) -- note, this will be different for you!

Exception 3:

Edited Default Security List for <your-vcn-name>. Removed rule that allows ssh (port 22) traffic from all (0.0.0.0/0). Added rule to accept SSH traffic from Bastion ip (10.0.0.49/32) -- note, this will be different for you!

Variables file

Create your own variable file and include in commandline as suggested below, file name vars_fra.tfvars.

Use sample file vars.tfvars.SAMPLE as a starting point.

Usage

terraform plan --out=oci-core-gpu.tfplan --var-file=vars_fra.tfvars

terraform apply ....
