## Simulated hash per deployment, normally used by CI/CD system
HASH=$(openssl rand -hex 12)

cd infra

## Initialize Terraform
terraform init

## Generate Terraform plan file
terraform plan -var hash=${HASH} -out=infrastructure.tf.plan

## Provision resources
terraform apply -auto-approve infrastructure.tf.plan
rm -rf infrastructure.tf.plan

## Read ECR repository URL to push Docker image with app to registry
REPOSITORY_URL=$(terraform output -raw ecr_repository_url)

    docker login --username AWS --password-stdin ${REPOSITORY_BASE_URL}

## Build Docker image and tag new versions for every deployment
docker build --platform linux/amd64 -t nexgeneerz/$1 ../app
docker tag nexgeneerz/$1:latest ${REPOSITORY_URL}:latest
docker tag nexgeneerz/$1:latest ${REPOSITORY_URL}:${HASH}
docker push ${REPOSITORY_URL}:latest
