Module 2 Terraform: "local-exec provisioner error"

[rbncyber27]

I have encountered an error in line 474 with the null_resource related to not finding the path to the \bin\bash within the environment where the system should be running.

I have tried multiple alternatives but it doesn't seem to work.

The code:
_```
resource "null_resource" "rds_endpoint" {
provisioner "local-exec" {
command = <<EOF
RDS_URL="${aws_db_instance.database-instance.endpoint}"
RDS_URL=$${RDS_URL::-5}
sed -i "s,RDS_ENDPOINT_VALUE,$RDS_URL,g" ${path.module}/resources/ecs/task_definition.json
EOF
interpreter = ["/bin/bash", "-c"]
}

depends_on = [
aws_db_instance.database-instance
]
}

The error:

null_resource.rds_endpoint (local-exec): Executing: ["/bin/bash" "-c" "RDS_URL=\"aws-goat-db.c9as8i4mcjpd.us-east-1.rds.amazonaws.com:3306\"\nRDS_URL=${RDS_URL::-5}\nsed -i \"s,RDS_ENDPOINT_VALUE,$RDS_URL,g\" ./resources/ecs/task_definition.json\n"]

Hi @rbncyber27,

It looks like you're deploying on Windows, which is causing the null_resource to fail since /bin/bash isn’t available in %PATH%. Since Windows does not have /bin/bash by default, the script is unable to execute as expected. To fix this, try deploying via GitHub Actions, as the workflows run on Ubuntu, where /bin/bash is available. Alternatively, you can use WSL or a Linux-based environment.

Let us know if you need further help!

Best,
