Ansible Tower 未在 ec2-remote-facts 模块中正确注册变量

Question

当我不在 Ansible Tower 上运行 ec2-remote-facts 模块时，它可以正常工作。 下面的第一个示例（不使用 Tower）包括我在后续任务中使用的所有 block_device_mapping 信息。

从长远来看，这是我要使用 Tower 的一个大问题。 我的代码对于两个示例都是相同的。 任何可以引导我走向正确方向的想法。

我唯一的想法是，由于它不是核心模块，Ansible Tower 没有完美地同步到模块的最新代码。 但我很困惑。 谢谢！

Ansible 版本 - ansible 2.2.0.0（在 Ubuntu 上运行）

Ansible Tower 版本 - Tower 版本 3.0.3（在 Centos 上运行）

---下面的例子----

Answer 1

我猜你的 Tower 盒子上确实有旧的 Ansible 版本。

截至今天，官方 Ansible Tower Vagrant 盒子（ansible/tower (virtualbox, 3.0.3)）里面有 2.1.2 版：

[vagrant@ansible-tower ~]$ ansible --version
ansible 2.1.2.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = Default w/o overrides

而ec2_remote_facts在这个版本中没有block_device_mapping 。
因此，请在您的 Tower 盒上更新 Ansible 或应用此补丁。
