I am studying Terraform. Currently, I am deploying my application to AWS. I use EC2, Cluster, Task Definition, ASG, and others.

My application deployment includes building a Docker image with my Java code, which is located in another GitHub repository. I am using GitHub Actions for deployment.

Now, part of my Terraform code looks like this:

resource "null_resource" "build_docker_image" {

provisioner "local-exec" {
working_dir = var.work_directory
command     = <<EOF
aws ecr get-login-password --region ${var.region} | docker login --username AWS --password-stdin ${data.aws_caller_identity.current_user.account_id}.dkr.ecr.${var.region}.amazonaws.com && cd ${var.work_directory} && chmod +x ./mvnw && ./mvnw clean package && docker build -t ${var.back_repository_name} . && docker tag ${var.back_repository_name}:latest ${data.aws_caller_identity.current_user.account_id}.dkr.ecr.${var.region}.amazonaws.com/${var.back_repository_name}:latest && docker push ${data.aws_caller_identity.current_user.account_id}.dkr.ecr.${var.region}.amazonaws.com/${var.back_repository_name}:latest
EOF
}

triggers = {
"run_at" = timestamp()
}

}

However, this command is very long because it is written in one line.

I tried to make this line shorter, but I could not succeed. If I write this command on multiple lines, when I run my Terraform (terraform apply), only the first line runs.

I tried using bash, but it did not work (<3>WSL (34) ERROR: CreateProcessParseCommon:711: Failed to translate):

  provisioner "local-exec" {
    working_dir = var.work_directory
    command     = <<EOF
bash deploy.sh ${var.region} ${data.aws_caller_identity.current_user.account_id} ${var.back_repository_name}
    EOF
  }


#!/bin/bash
aws ecr get-login-password --region $1 | docker login --username AWS --password-stdin $2.dkr.ecr.$1.amazonaws.com
docker build -t $3 .
docker tag $3:latest $2.dkr.ecr.$1.amazonaws.com/$3:latest
docker push $2.dkr.ecr.$1.amazonaws.com/$3:latest

Also, I try use ‘ / ‘ or ‘ n ‘ but it is not work too.

Please help me solve the problem. May be there are patters for building docker image.
