Add Terraform equivalents for all Bicep infrastructure templates

[Copilot]

Provides Terraform implementations alongside existing Bicep templates for ACA, ACI, AKS, and ACR deployments. Both IaC tools now coexist, allowing users to choose based on their multi-cloud strategy or Azure-native preference.

Infrastructure Conversions

Azure Container Apps (ACA)

• Resource group, ACR, Container Apps Environment, Container App
• Auto-scaling (1-3 replicas) with HTTP rules
• External ingress with registry secret injection

Azure Container Instance (ACI)

• Resource group, ACR, Container Instance
• Public IP with configurable CPU/memory
• Default fallback to aci-helloworld image

Azure Kubernetes Service (AKS)

• Resource group, ACR, AKS cluster
• Kubelet identity with AcrPull role assignment
• RBAC disabled (matches Bicep configuration)
• Configurable node pool (count, VM size, OS disk)

Azure Container Registry (ACR)

• Standalone module for reuse
• Basic SKU with admin access

Design Notes

• Inline resources instead of module hierarchies for simplicity
• String types for CPU/memory match Azure API requirements ("0.5", "1Gi")
• Registry credentials always passed to match Bicep behavior
• Sensitive outputs (passwords, usernames) properly marked
• .gitignore updated for Terraform state files

Usage

cd azd/aca
terraform init
terraform apply \
  -var="environment_name=dev" \
  -var="location=eastus"

Or create terraform.tfvars:

environment_name = "dev"
location         = "eastus"
container_image  = "myapp"
cpu_cores        = "1.0"
memory_in_gb     = "2Gi"

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• checkpoint-api.hashicorp.com
  • Triggering command: ./terraform ./terraform --version (dns block)
  • Triggering command: /tmp/terraform /tmp/terraform fmt -check (dns block)
  • Triggering command: /tmp/terraform /tmp/terraform init -backend=false 53 -j ACCEPT (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
