Terraform Search and Bulk Import
Discover existing cloud resources using declarative queries and generate configuration for bulk import into Terraform state.
References:
When to Use
- Bringing unmanaged resources under Terraform control
- Auditing existing cloud infrastructure
- Migrating from manual provisioning to IaC
- Discovering resources across multiple regions/accounts
IMPORTANT: Check Provider Support First
BEFORE starting, you MUST verify the target resource type is supported:
# Check what list resources are available
./scripts/list_resources.sh aws # Specific provider
./scripts/list_resources.sh # All configured providers
Decision Tree
-
Identify target resource type (e.g., aws_s3_bucket, aws_instance)
-
Check if supported: Run
./scripts/list_resources.sh <provider> -
Choose workflow:
- ** If supported**: Check for terraform version available.
- ** If terraform version is above 1.14.0** Use Terraform Search workflow (below)
- ** If not supported or terraform version is below 1.14.0 **: Use Manual Discovery workflow (see references/MANUAL-IMPORT.md)
Note: The list of supported resources is rapidly expanding. Always verify current support before using manual import.
Prerequisites
Before writing queries, verify the provider supports list resources for your target resource type.
Discover Available List Resources
Run the helper script to extract supported list resources from your provider:
# From a directory with provider configuration (runs terraform init if needed)
./scripts/list_resources.sh aws # Specific provider
./scripts/list_resources.sh # All configured providers
Or manually query the provider schema:
terraform providers schema -json | jq '.provider_schemas | to_entries | map({key: (.key | split("/")[-1]), value: (.value.list_resource_schemas // {} | keys)})'
Terraform Search requires an initialized working directory. Ensure you have a configuration with the required provider before running queries:
# terraform.tf
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "~> 6.0"
}
}
}
Run terraform init to download the provider, then proceed with queries.
Terraform Search Workflow (Supported Resources Only)
- Create
.tfquery.hclfiles withlistblocks defining search queries - Run
terraform queryto discover matching resources - Generate configuration with
-generate-config-out=<file> - Review and refine generated
resourceandimportblocks - Run
terraform planandterraform applyto import
Query File Structure
Query files use .tfquery.hcl extension and support:
providerblocks for authenticationlistblocks for resource discoveryvariableandlocalsblocks for parameterization
# discovery.tfquery.hcl
provider "aws" {
region = "us-west-2"
}
list "aws_instance" "all" {
provider = aws
}
List Block Syntax
list "<list_type>" "<symbolic_name>" {
provider = <provider_reference> # Required
# Optional: filter configuration (provider-specific)
# The `config` block schema is provider-specific. Discover available options using `terraform providers schema -json | jq '.provider_schemas."registry.terraform.io/hashicorp/<provider>".list_resource_schemas."<resource_type>"'`
config {
filter {
name = "<filter_name>"
values = ["<value1>", "<value2>"]
}
region = "<region>" # AWS-specific
}
# Optional: limit results
limit = 100
}
Supported List Resources
Provider support for list resources varies by version. Always check what's available for your specific provider version using the discovery script.
Query Examples
Basic Discovery
# Find all EC2 instances in configured region
list "aws_instance" "all" {
provider = aws
}
Filtered Discovery
# Find instances by tag
list "aws_instance" "production" {
provider = aws
config {
filter {
name = "tag:Environment"
values = ["production"]
}
}
}
# Find instances by type
list "aws_instance" "large" {
provider = aws
config {
filter {
name = "instance-type"
values = ["t3.large", "t3.xlarge"]
}
}
}
Multi-Region Discovery
provider "aws" {
region = "us-west-2"
}
locals {
regions = ["us-west-2", "us-east-1", "eu-west-1"]
}
list "aws_instance" "all_regions" {
for_each = toset(local.regions)
provider = aws
config {
region = each.value
}
}
Parameterized Queries
variable "target_environment" {
type = string
default = "staging"
}
list "aws_instance" "by_env" {
provider = aws
config {
filter {
name = "tag:Environment"
values = [var.target_environment]
}
}
}
Running Queries
# Execute queries and display results
terraform query
# Generate configuration file
terraform query -generate-config-out=imported.tf
# Pass variables
terraform query -var='target_environment=production'
Query Output Format
list.aws_instance.all account_id=123456789012,id=i-0abc123,region=us-west-2 web-server
Columns: <query_address> <identity_attributes> <name_tag>
Generated Configuration
The -generate-config-out flag creates:
# __generated__ by Terraform
resource "aws_instance" "all_0" {
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
# ... all attributes
}
import {
to = aws_instance.all_0
provider = aws
identity = {
account_id = "123456789012"
id = "i-0abc123"
region = "us-west-2"
}
}
Post-Generation Cleanup
Generated configuration includes all attributes. Clean up by:
- Remove computed/read-only attributes
- Replace hardcoded values with variables
- Add proper resource naming
- Organize into appropriate files
# Before: generated
resource "aws_instance" "all_0" {
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
arn = "arn:aws:ec2:..." # Remove - computed
id = "i-0abc123" # Remove - computed
# ... many more attributes
}
# After: cleaned
resource "aws_instance" "web_server" {
ami = var.ami_id
instance_type = var.instance_type
subnet_id = var.subnet_id
tags = {
Name = "web-server"
Environment = var.environment
}
}
Import by Identity
Generated imports use identity-based import (Terraform 1.12+):
import {
to = aws_instance.web
provider = aws
identity = {
account_id = "123456789012"
id = "i-0abc123"
region = "us-west-2"
}
}
Verifying Imported State
After running terraform apply to import resources, verify what actually landed in state.
Prefer the documented, stable, and more token-efficient commands over reading the raw state
file:
# Confirm resources are now managed (also confirms addresses)
terraform state list
# Inspect resolved attribute values for imported resources
terraform show -json | jq '.values.root_module.resources[] | {address, type, name}'
terraform show -json requires providers to be installed (terraform init), since it
renders values against provider schemas. Fall back to the raw state
(terraform state pull / terraform.tfstate) only when providers aren't available and
init can't run, you need only coarse info (addresses, outputs, serial/lineage), or you
must avoid executing Terraform. Avoid parsing the raw version-4 state format as a stable
interface. Note: state contains sensitive values in plaintext in every format — never
echo state contents into logs or output.
Best Practices
Query Design
- Start broad, then add filters to narrow results
- Use
limitto prevent overwhelming output - Test queries before generating configuration
Configuration Management
- Review all generated code before applying
- Remove unnecessary default values
- Use consistent naming conventions
- Add proper variable abstraction
Troubleshooting
| Issue | Solution |
|---|---|
| "No list resources found" | Check provider version supports list resources |
| Query returns empty | Verify region and filter values |
| Generated config has errors | Remove computed attributes, fix deprecated arguments |
| Import fails | Ensure resource not already in state |
