Hello everyone!

I'm trying to use ministack to study terraform with AWS, and I'm facing problems with re-run to create an EC2

minstask env:

docker run -p 4566:4566  nahuelnucera/ministack

terraform version:

Terraform v1.14.8
on linux_amd64
+ provider registry.terraform.io/hashicorp/aws v6.40.0

Terraform file:

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "6.40.0"
    }
  }
}

# Configure the AWS Provider
provider "aws" {
  region = "us-east-1"
}

resource "aws_vpc" "my_vpc" {
  cidr_block           = "10.0.0.0/16"
  enable_dns_support   = false
  enable_dns_hostnames = false
  enable_network_address_usage_metrics = false
  tags = {
    Name        = "my_vpc"
    Environment = "dev"
    ManagedBy   = "Terraform"
  }
}

resource "aws_subnet" "subnet1" {
  vpc_id     = aws_vpc.my_vpc.id
  cidr_block = "10.0.1.0/24"
  tags = {
    Name        = "subnet1"
    Environment = "dev"
    ManagedBy   = "Terraform"
  }
}

  vpc_id = aws_vpc.my_vpc.id

  vpc_id = aws_vpc.my_vpc.id

  route {
    cidr_block = "0.0.0.0/0"

  }

  tags = {

  instance_type               = "t3.micro"
  depends_on = [ aws_security_group.allow_tls ]
}

resource "aws_security_group" "allow_tls" {
  name        = "allow_tls"
  description = "Allow TLS inbound traffic and all outbound traffic"
  vpc_id      = aws_vpc.my_vpc.id

second time run with the same configuration:

Any ideas what I could be doing wrong?

Hey @doug2901 we fixed that this morning (it was an issue with Ministack) could you try with latest version?

Hi @Nahuel990, now it's working fine.

Thanks a lot for the quick answer and the fix.
