Question

下面，我尝试运行一个命令，该命令包含来自先前输出的输入，在本例中为copy flash:file01 flash:file02，其中有2来自REGEX_FILTERING任务。

- name: REGEX_FILTERING
  command: "cat /home/ubuntu/show_switch.txt"
  register: line1
- debug: var="{{ line1.stdout_lines | regex_replace('(?<!\*).?') }}"
  register: number

- name: COMMAND_INPUT
  cli_command:
         command: 'copy flash:file01 flash:file0 {{ number }}'
         prompt: '[confirm]'
         answer: ''

这是错误消息：

<ommited>
 "stdout_lines": [
        "Switch/Stack Mac Address : d4a0.2ae9.ec00",
        "                                           H/W   Current",
        "----------------------------------------------------------",
        " 1       Member 001f.9df6.2d80     5      0       Ready               ",
        "*2       Master d4a0.2ae9.ec00     15     0       Ready               ",
        " 3       Member 0016.c733.cd00     5      0       Ready"
    ]
}

Answer 1

"command": "copy flash:file01 flash:file0 {'failed': False, u'2': u'2', 'changed': False}",

之所以发生，是因为register: number实际上不是数字，而是debug:输出的结果。由于number是python dict，因此将其注入到命令中后，就可以像在str()

上调用dict一样对其进行序列化。

您更可能希望在任务中本地捕获该变量，使其成为 just ，它是jinja2表达式的结果，而不是ansible任务的结果：

- cli_command:
     command: 'copy flash:file01 flash:file0 {{ number }}'
  vars:
     number: "{{ line1.stdout_lines | regex_replace('(?<!\*).?') }}"

我还怀疑您会更满意line1.stdout，它是整个输出的str，而不是line1.stdout_lines，它是list的{{1}} ，使str变得regex_replace有点奇怪-实在让我惊讶的是，实际上我什至允许您这么做

使用变量输入的Ansible命令无法执行
