Lab 34: Copy Data to S3 Using Terraform

The Nautilus DevOps team is presently immersed in data migrations, transferring data from on-premise storage systems to AWS S3 buckets. They have recently received some data that they intend to copy to one of the S3 buckets.

S3 bucket named devops-cp-14719 already exists. Copy the file /tmp/devops.txt to s3 bucket devops-cp-14719 using Terraform. The Terraform working directory is /home/bob/terraform. Update the main.tf file (do not create a separate .tf file) to accomplish this task.

The Terraform working directory is /home/bob/terraform.

Note: Right-click under the EXPLORER section in VS Code and select Open in Integrated Terminal to launch the terminal.

# /home/bob/terraform/main.tf

resource "aws_s3_bucket" "my_bucket" {
  bucket = "devops-cp-14719"
  # Note: The 'acl' argument is deprecated. 
  # For this specific scenario (using an existing bucket), 
  # we'll assume the bucket definition is provided for context
  # but the object resource is what performs the file copy.
  # We will keep the original bucket definition as provided.
  acl    = "private" 

  tags = {
    Name        = "devops-cp-14719"
  }
}

# Add this resource to copy the file to the S3 bucket.
resource "aws_s3_object" "devops_file" {
  # The key is the desired name of the file in the S3 bucket.
  key    = "devops.txt"
  
  # The bucket argument specifies the target bucket name.
  bucket = aws_s3_bucket.my_bucket.bucket
  
  # The source argument is the local path to the file you want to upload.
  source = "/tmp/devops.txt"
  
  # The 'etag' ensures Terraform can detect if the local file changes,
  # forcing an update to the S3 object.
  etag = filemd5("/tmp/devops.txt")
}

terraform init
# or apply forcefully without creating plan and applying it
terraform apply -auto-approve
