Documentation
oci-vcn
Production VCN with public/private subnets, internet/NAT/service gateways,
route tables, NSGs and IPv6 — the module every OCI tenancy starts with. Works
with Terraform and OpenTofu (>= 1.6), OCI provider >= 8.0, < 9.0.
Secure defaults:
- Private subnets prohibit public IPs on VNICs and route via NAT/service gateway
- No security rules are opened implicitly — every rule is an explicit NSG entry
- Service-gateway route keeps Oracle Services Network traffic (Object Storage, OS updates) off the public internet
- IPv6 is opt-in (VCN-level
enable_ipv6+ per-subnetipv6_index/64 carve)
Requirements
- Terraform or OpenTofu
>= 1.6 - Provider
oracle/oci>= 8.0, < 9.0

Related modules
oci-remote-peering
A remote peering connection is half a link until the requestor connects to the acceptor, and a PEERED connection with no DRG route import and no VCN route rule passes nothing while reading as connected. Acceptor and requestor halves from one module, the peering status exported, and an output that lists the routes and security rules that live outside it and are the usual reason no packets cross.
oci-fastconnect
One virtual circuit is one cable that goes down for maintenance, and the SLA assumes two; BFD is off by default, leaving a failed link to BGP hold timers for up to ninety seconds; and a circuit without a gateway is PROVISIONED and reaches no VCN. BFD on, the DRG required, a redundant partner circuit declared or the single circuit accepted by name, and the redundancy metadata exported.
oci-local-peering
A local peering gateway with no peer stays NEW forever, and a PEERED pair with no route rule sending the other CIDR to the gateway passes nothing while reading as connected. Both gateways created and connected from one call, a route table with the rule to the peer created on each side for the subnets that should reach across, overlap refused, and an output that says it is not transitive.
oci-nat-gateway
A NAT gateway for an existing VCN with the private route table that sends subnets through it, because a gateway no table points at forwards nothing. The NAT address is ephemeral unless a reserved public IP is attached, and every allow-list that named it breaks on recreation; the ephemeral address is accepted by name. block_traffic, the kill switch, stays off and is exported.
oci-site-to-site-vpn
Every OCI IPSec tunnel is created with IKE version 1 unless told otherwise, and negotiates from a compatibility list that still accepts SHA-1, AES-128 and DH group 2 - so the weakest option a peer proposes is what it gets, and the tunnel shows UP. IKEv2 on both tunnels, explicit proposals for both phases with the weak ones refused by validation, BGP routing, and one configured tunnel only by name.
oci-drg-hub
Dynamic Routing Gateway with VCN attachments, custom DRG route tables, remote peering and IPSec/FastConnect attach points.
