是的，可以在不运行中的EC2实例上运行Terraform/Ansible脚本。以下是一个解决方法的代码示例：

使用Terraform远程执行脚本：

provider "aws" {
  region = "us-west-2"
}

resource "aws_instance" "example" {
  ami           = "ami-0c94855ba95c71c99"
  instance_type = "t2.micro"
}

resource "null_resource" "run_script" {
  triggers = {
    instance_id = aws_instance.example.id
  }

  provisioner "local-exec" {
    command = "terraform apply -target=null_resource.run_script -auto-approve"
  }

  provisioner "remote-exec" {
    inline = [
      "echo 'Running script on EC2 instance'",
      "sudo apt-get update",
      "sudo apt-get install -y ansible",
      "ansible-playbook -i 'localhost,' -c local playbook.yml"
    ]

    connection {
      type        = "ssh"
      host        = aws_instance.example.public_ip
      user        = "ec2-user"
      private_key = file("~/.ssh/id_rsa")
    }
  }
}

上述代码中，我们创建了一个EC2实例并使用Terraform的remote-exec provisioner在实例上运行Ansible脚本。

使用Ansible远程执行脚本：

---
- name: Run script on EC2 instance
  hosts: localhost
  connection: local
  gather_facts: false

  tasks:
    - name: Install required packages
      become: true
      apt:
        name: ansible
        state: present

    - name: Run playbook
      become: true
      hosts: all
      tasks:
        - name: Execute script
          shell: /path/to/script.sh

上述代码是一个简单的Ansible playbook示例，用于在远程EC2实例上执行脚本。

要使用Ansible在不在运行中的EC2实例上执行脚本，您需要确保Ansible在本地机器上安装，并在Ansible playbook中指定远程EC2实例的连接信息。

请注意，为了安全起见，您可能需要更新上述代码中的连接信息和脚本路径，以适应您的具体情况。
