Ansible 中如何调用架构事实？

我正在寻找事实，其中包含以下信息：

$ dpkg --print-architecture
amd64

我找不到它了：

$ ansible host -m setup | grep amd64
        "BOOT_IMAGE": "/boot/vmlinuz-4.19.0-6-amd64", 
    "ansible_kernel": "4.19.0-6-amd64", 
        "BOOT_IMAGE": "/boot/vmlinuz-4.19.0-6-amd64", 

Using ansible.builtin.shell这是一个坏主意。因为它每次都会改变状态。我建议使用映射可靠的事实 https://docs.ansible.com/ansible/latest/user_guide/playbooks_vars_facts.html.
