将 Ansible 变量从 Unicode 转换为 ASCII

问题描述

我在远程系统上获取命令的输出并将其存储在一个变量中.然后使用它来填充放置在系统上的文件模板.

I'm getting the output of a command on the remote system and storing it in a variable. It is then used to fill in a file template which gets placed on the system.

- name: Retrieve Initiator Name
  command: /usr/sbin/iscsi-iname
  register: iscsiname

- name: Setup InitiatorName File
  template: src=initiatorname.iscsi.template dest=/etc/iscsi/initiatorname.iscsi

initiatorname.iscsi.template 文件包含:

The initiatorname.iscsi.template file contains:

InitiatorName={{ iscsiname.stdout_lines }}

然而，当我运行它时，我得到一个包含以下内容的文件:

When I run it however, I get a file with the following:

InitiatorName=[u'iqn.2005-03.org.open-iscsi:2bb08ec8f94']

我想要的:

InitiatorName=iqn.2005-03.org.open-iscsi:2bb08ec8f94

我做错了什么?

我意识到我可以使用echo "InitiatorName=$(/usr/sbin/iscsi-iname)" >/etc/iscsi/initiatorname.iscsi"将其写入文件，但这似乎是一种不可靠的方式这样做.

I realize I could write this to the file with an "echo "InitiatorName=$(/usr/sbin/iscsi-iname)" > /etc/iscsi/initiatorname.iscsi" but that seems like an un-Ansible way of doing it.

提前致谢.

推荐答案

使用过滤器避免 unicode 字符串:

Use a filter to avoid unicode strings:

InitiatorName = {{ iscsiname.stdout_lines | to_yaml }}
