ansible 2.0中的模板传输错误

Question

我有一个非常简单的角色，它在 ansible 1.9.4 中运行良好，但是当我运行使用 ansible 2.0 的相同角色时，我在模板传输期间遇到错误。 ansible 2.0 中的模板模块有什么变化吗？

我的角色布局：

.
|-- handlers
|   `-- main.yml
|-- tasks
|   `-- main.yml
|-- templates
|   |-- etc_default_isc-dhcp-server.j2
|   `-- etc_dhcp_dhcpd.conf.j2
`-- vars
    `-- main.yml

我已经使用 ansible ping 模块测试了与远程服务器的连接：

ansible -m ping all -u vagrant -k
SSH password:

192.168.33.10 | SUCCESS => {
    "changed": false,
    "ping": "pong"
}

这是我遇到错误的任务：

- name: Write the modified 'isc-dhcp-server' file
   template: 
    src: templates/etc_default_isc-dhcp-server.j2 
    dest: /etc/default/isc-dhcp-server 
    backup: yes

这是一个错误：

Answer 1

这看起来与我一年多前看到的东西非常相似，paramiko 选择 SFTP 进行文件传输。使用“-c ssh”尝试运行你的剧本，看看是否能解决你的问题

Answer 2

由于您没有使用 SSH 密钥进行身份验证，因此您必须在运行带有 -vvv 选项的 ansible-playbook 之前尝试运行 "export ANSIBLE_SCP_IF_SSH=y"。

如果仍然无法正常工作并且错误消息发生变化，请 post 新的错误消息，以便我们可以继续找到解决您问题的方法。
