I want to create an IaC script using Terraform, it will create a set of resources in AWS. One of the resources is an Ubuntu virtual machine that will run a GridDB database. I used this doc as a starting point – https://docs.griddb.net/latest/gettingstarted/using-apt/. According to the document, the default admin credentials are admin/admin, I’d like my script to change the password to some unique value (which will be unique for each customer). I am not quite sure how to proceed, since the command “gs_passwd admin” expects me to write the new password interactively. The example of code is shown below, could you please advise?

resource "aws_instance" "db01" {
    ami = "ami-0750f57b80795fb10"
    instance_type = "t2.micro"
    user_data = <<-EOF
        #!/bin/bash
        echo "deb https://www.griddb.net/apt griddb/5.5 multiverse" >  /etc/apt/sources.list.d/griddb.list
        wget -qO - https://www.griddb.net/apt/griddb.asc | apt-key add -
        apt update
        apt install griddb-meta
        systemctl start gridstore
        gs_passwd admin
        EOF
    user_data_replace_on_change = true
    security_groups = [aws_security_group.group01.id]
    lifecycle {
        create_before_destroy = true
    }  
    tags = {
        name = "Database Node"
    }
}
