Maintain Code & State Use as source of truth. Inject Dependencies Decouple resources to mitigate impact. Practices @joatmon08
© 2023 HASHICORP 5 Declarative Define expected state of infrastructure
in configuration files that you can version, reuse, and share. locals { annotation = "orchestrator:terraform" } resource "aci_tenant" "dev" { description = "This tenant is created by Terraform" name = "${var.prefix}_tenant" annotation = local.annotation } resource "aci_application_profile" "dev" { tenant_dn = aci_tenant.dev.id name = "${var.prefix}_ap" annotation = local.annotation } resource "aci_vrf" "dev" { tenant_dn = aci_tenant.dev.id name = "${var.prefix}_vrf" annotation = local.annotation } @joatmon08

Maintain Code & State Use as source of truth. Inject Dependencies Decouple resources to mitigate impact. Practices @joatmon08
© 2023 HASHICORP 9 Manage Code & State Establish a
source of truth with configuration and state. terraform { cloud { organization = "hashicorp-team-da-beta" workspaces { tags = ["datacenter", "networking", "source:cli"] } } } resource "aci_tenant" "dev" { description = "This tenant is created by Terraform" name = "${var.prefix}_tenant" annotation = local.annotation } @joatmon08

Maintain Code & State Use as source of truth. Inject Dependencies Decouple resources to mitigate impact. Practices @joatmon08
© 2023 HASHICORP 14 Inject Dependencies Retrieve metadata from an
abstraction to change downstream dependencies independently. data "aws_availability_zones" "available" { state = "available" filter { name = "group-name" values = [var.region] } } resource "aws_subnet" "public" { count = var.public_subnet_count vpc_id = aws_vpc.nfd.id availability_zone = data.aws_availability_zones.available.names[count .index] // omitted } @joatmon08

self-service of properly configured network infrastructure. locals { annotation = "orchestrator:terraform" } resource "aci_tenant" "dev" { description = "This tenant is created by Terraform" name = "${var.prefix}_tenant" annotation = local.annotation } resource "aci_application_profile" "dev" { tenant_dn = aci_tenant.dev.id name = "${var.prefix}_ap" annotation = local.annotation } resource "aci_vrf" "dev" { tenant_dn = aci_tenant.dev.id name = "${var.prefix}_vrf" annotation = local.annotation } @joatmon08

for specific attributes and functionality. // VARIABLE VALIDATION variable "region" { type = string default = "us-east-1" description = "AWS Region" validation { condition = startswith(var.region, "us-") error_message = "Only use AWS regions in US" } } // TEST aws_subnets_have_correct_mask = rule { all aws_subnets as _, aws_subnets { aws_subnets.values.cidr_block contains "/24" } } @joatmon08

custom policies to check for compliant and secure infrastructure configuration. // Policies to Run policy "public_access" { query = "data.terraform.policies.public_access.deny" enforcement_level = "mandatory" } // Policy Definition package terraform.policies.public_access import input.plan as tfplan deny[msg] { r := tfplan.resource_changes[_] r.type == "aws_security_group" r.change.after.ingress[_].cidr_blocks[_] == "0.0.0.0/0" msg := sprintf("%v has 0.0.0.0/0 as allowed ingress", [r.address]) } @joatmon08
