- Updated to use 4.xx of the Terraform provider, testing still in progress - please report any issues you find.**
- Now optionally includes a security report: "tfsec" CRITICAL and HIGH issues
This utility 'AWS to Terraform' (aws2tf) reads an AWS Account and generates all the required terraform configuration files (.tf) from each of the composite AWS resources
It also imports the terraform state using a
"terraform import ...." command
And finally runs a
"terraform plan" command
There should hopefully be no subsequent additions or deletions reported by the terraform plan command as all the appropriate terraform configuration files will have have automatically been created.
- The tool is written for the bash shell script & Python3 and has been tested on macOS 11.6.
- AWS cli (v2) version 2.9.0 or higher needs to be installed and you need a login with at least "Read" privileges.
- terraform version v1.3.7 or higher needs to be installed.
- jq version 1.6 or higher
- yq optional for advanced stack processing
- tfsec version 1.27.5 or later (https://github.com/aquasecurity/tfsec)
Running the tool in your local shell (bash) required these steps:
- Unzip or clone this git repo into an empty directory
- login to the AWS cli (aws configure)
- run the tool
To generate the terraform files for an account and stop after a "terraform validate":
./aws2tf.sh -v yes
Or if you have a lot of resources in your accoutn try using -t to restrict the number of resources you scan. So if your interested in a type or group for example: Transit Gateway resources:
./aws2tf.sh -v yes -t tgw
terraform validate
Success! The configuration is valid.
Or there may be some kind of error as trying to test everyone's AWS combinations in advance isn't possible.
If you happen to find one of these errors please open an issue here and paste in the error and it will get fixed.
Once the validation is ok you can remove the -v which then also runs the terraform plan.
To generate the terraform files for an entire AWS account, import the resources and perform a terraform plan:
./aws2tf.sh
*Note this will take some time - consider using a -t filter instead - and the adding resources with a subsequent run using -c and -f - see below.
To extract all AWS account Policies and Roles:
./aws2tf.sh -t iam
To generate the terraform files for an EKS cluster named "mycluster"
./aws2tf.sh -t eks -i mycluster
To add App Mesh resources
./aws2tf.sh -t appmesh -c yes -f yes
The -c yes is used to "continue" from where we left off,
The -f yes is the "fast forward" action it skips past blocks of resources that were completed during the last run.
The two used in combination should quickly have your run progressing from where you left off
To get a selection of resources use the -t option The currently supported types are:
- acm - ACM resources
-t acm - apigw - API GW restAPI resources
-t apigw - appmesh - App Mesh resources
-t appmesh - appstream - AppStream v2.0 resources
-t appstream - artifact - CodeArtifact resources
- athena - Athena resources
- code - Code* resources
-t code - cfront - CloudFront resources
- cloudform - CloudFormation Stacks
- cognito - Cognito resources
-t cognito - config - AWS config resources
-t config - eb - EventBridge resources
-t eb - ec2 - Instances (running state only)
- ecs - An ECS cluster and it's related resources
-t ecs -i Cluster-Name - efs - EFS file systems - individual filesystems with
-t efs -i fs-xxxxxxxx - eks - An EKS cluster and it's related resources
-t eks -i Cluster-Name - emr - get all active EMR clusters
- glue - Glue tables and partitions
- iam - All IAM related users, groups, policies & roles
-t iam - kinesis - Kinesis resources
- kms - KMS keys and aliases
-t kms - lambda - Lambda resources
-t lambda - lf - Lake Formation resources
-t lf - org - AWS Organizations
-t org - params - SSM parameters
-t params - privatelink - Private Link resources
- rds - RDS database resources
-t rds - s3 - s3 buckets and policies
- sagemaker - SageMaker resources
-t sagemaker - secrets - Secrets Manager secrets
-t secrets - sc - Service Catalog resources
-t sc - sns - SNS resources
-t sns - sqs - SQS queues
-t sqs - spot - spot requests
-t spot - tgw - Transit Gateway resources
-t tgw <-i transit-gateway-id> - users - IAM Users and Groups
- vpc - A VPC and it's related resources
-t vpc <-i VPC-id>
To get all the VPC related resources in a particular VPC
./aws2tf.sh -t vpc -i vpc-xxxxxxxxx
To use a specific region and profile
./aws2tf.sh -t vpc -i vpc-xxxxxxxxx -r eu-west-1 -p default
Cumulative mode allows you to add additional state & terraform files form a previous aws2tf run
If for example you want to get several VPCs you can use the cumulative mode:
To get all the VPC related resources in three particular VPC's
./aws2tf.sh -t vpc -i vpc-aaaaaaaaa
./aws2tf.sh -t vpc -i vpc-bbbbbbbbb -c yes
./aws2tf.sh -t vpc -i vpc-ccccccccc -c yes
Be patient - lots of output is given as aws2tf:
- Loops through each provider
- Creates the requited *.tf configuration files in the "generated" directory
- Performs the necessary 'terraform import' commands
- And finally runs a 'terraform plan'
- Optionally if tfsec is installed - produces a security report
aws2tf maintains state in it's own local directory:
generated/tf../
When using cumulative mode this same state file is used / added to.
It is not possibel at this time to use your own state location (eg. on s3)
To get all the resources in a deployed Stack Set
./aws2tf.sh -s <stack set name>
