Terraform with Localstack basic setup doesn't work - terraform-provider-aws

Question

I want to try basic setup for localstack with terraform.
My docker-compose file, from the localstack docs
version: "3.8"
services:
localstack:
container_name: "${LOCALSTACK_DOCKER_NAME-localstack_main}"
image: localstack/localstack
ports:
- "127.0.0.1:4566:4566" # LocalStack Gateway
- "127.0.0.1:4510-4559:4510-4559" # external services port range
- "127.0.0.1:53:53" # DNS config (only required for Pro)
- "127.0.0.1:53:53/udp" # DNS config (only required for Pro)
- "127.0.0.1:443:443" # LocalStack HTTPS Gateway (only required for Pro)
environment:
- DEBUG=1
- LOCALSTACK_HOSTNAME=localhost
- PERSISTENCE=${PERSISTENCE-}
- LAMBDA_EXECUTOR=${LAMBDA_EXECUTOR-}
- LOCALSTACK_API_KEY=${LOCALSTACK_API_KEY-} # only required for Pro
- DOCKER_HOST=unix:///var/run/docker.sock
- SERVICES=s3
volumes:
- "${LOCALSTACK_VOLUME_DIR:-./volume}:/var/lib/localstack"
- "/var/run/docker.sock:/var/run/docker.sock"
My terraform file to create s3 bucket
# Public Cloud Configuration
provider "aws" {
region = "us-east-1"
access_key = "test123"
secret_key = "testabc"
skip_credentials_validation = true
skip_requesting_account_id = true
skip_metadata_api_check = true
endpoints {
s3 = "http://localhost:4566"
}
}
# Create Bucket
resource "aws_s3_bucket" "my_bucket" {
bucket = "bucket"
}
I got the next error when running the command terraform apply
│ Error: creating Amazon S3 (Simple Storage) Bucket (bucket): RequestError: send request failed
│ caused by: Put "http://bucket.localhost:4566/": dial tcp: lookup bucket.localhost on 10.222.50.10:53: no such host
│
│ with aws_s3_bucket.my_bucket,
│ on main.tf line 15, in resource "aws_s3_bucket" "my_bucket":
│ 15: resource "aws_s3_bucket" "my_bucket" {
I'm able to create s3 bucket manually in the localstack with command like
aws --endpoint-url http://localhost:4566 s3 mb s3://user-uploads
docker ps output
c9497bcff0e3 localstack/localstack "docker-entrypoint.sh" 23 minutes ago Up 18 minutes (healthy) 127.0.0.1:53->53/tcp, 127.0.0.1:443->443/tcp, 127.0.0.1:4510-4559->4510-4559/tcp, 127.0.0.1:4566->4566/tcp, 127.0.0.1:53->53/udp, 5678/tcp localstack_main
So why localstack is trying to access some different address like 192.168.178.1:53? Do I need to specify somewhere different address? Checked a number of tutorials and for everyone, the setup works fine.

Answer 1

The issue herein lies with your Terraform configuration. The following code inside main.tf works perfectly with tflocal (LocalStack's wrapper for Terraform CLI):
resource "aws_s3_bucket" "my_bucket" {
bucket = "bucket"
}
tflocal init
tflocal apply
If you don't wish to use tflocal, you would need to have a configuration like this:
provider "aws" {
access_key = "mock_access_key"
secret_key = "mock_secret_key"
region = "us-east-1"
s3_force_path_style = true
skip_credentials_validation = true
skip_metadata_api_check = true
skip_requesting_account_id = true
endpoints {
s3 = "http://s3.localhost.localstack.cloud:4566"
}
}
resource "aws_s3_bucket" "test-bucket" {
bucket = "my-bucket"
}
I hope this helps.

Answer 2

I solve it adding a property in provider aws
s3_use_path_style = true
Sample:
terraform {
required_version = ">= 0.12"
backend local {}
}
provider "aws" {
region = "localhost"
access_key = "local"
secret_key = "local"
skip_region_validation = true
skip_credentials_validation = true
skip_metadata_api_check = true
skip_requesting_account_id = true
s3_use_path_style = true // <<- this property here
endpoints {
dynamodb = "http://localhost:4566"
s3 = "http://localhost:4566"
}
}
// S3
resource "aws_s3_bucket" "my-bucket" {
bucket = "teste"
}
I hope help you
