如何在ansible变量中转义双引号

Question

我有一个 ansible playbook，它接受一个变量，传递一个带引号的变量（它需要），该变量将用于查询 DB

剧本

- name: Execute clear script
  script: scripts/clear-documents.sh {{ids}}

命令

ansible-playbook playbooks/maintenance.yml -i hosts -t clear -e ids=["foo", "bar"]

在这个过程中脚本接收输入为 [foo, bar] 而不是 ["foo", "bar"]

我尝试使用反斜杠转义，但没有帮助

ansible-playbook playbooks/maintenance.yml -i hosts -t clear -e ids=[\"foo\", \"bar\"]

在 playbook 中添加双引号，使输入类似于 "[foo,bar]" 而不是 ["foo", "bar"]

script: scripts/clear-documents.sh "{{ids}}"

我搜索了很多但没有得到任何合适的解决方案，有没有办法处理这个

注意： ansible 版本 - 2.2.3.0

Answer 1

您正在寻找的是quote，结合@JGK 对-e ids='["foo", "bar"]' 的正确用法，因为您没有在进入 ansible 的过程中引用它们，然后您没有引用他们在shell: 任务中退出 ansible

- shell: scripts/clear-documents.sh {{ ids | quote }}

Answer 2

正如How to escape backslash and double quote in Ansible (script module) 中提到的，您需要在您的shell 命令中用' ' 包围{{ ids }}。

#!/usr/bin/env ansible-playbook
- hosts: localhost
  gather_facts: false
  become: false
  tasks:
  - name: Escape characters for fun and profit
    vars:
      string_list: '["one", "two"]'
    shell: "echo '{{ string_list }}'"
    register: output1

  - name: Print it out
    debug:
      msg: "{{ output1 }}"

  - name: Don't escape characters
    vars:
      string_list: '["one", "two"]'
    shell: "echo {{ string_list }}"
    register: output2

  - name: Print it out
    debug:
      msg: "{{ output2 }}"

Answer 3

我有带有 kubectl 命令的剧本，当我想运行这个命令时，它无法避免引号并且理解这个目录不存在

--- 
    - 
      hosts: localhost

      vars_files: 
        - vars/main.yaml 


      tasks:     
        -
         shell:
           cmd: |
               kubectl exec -it -n {{ namespace }} {{ pod_name }} -- bash -c \"clickhouse-client --query "INSERT INTO customer FORMAT CSV" --user=test --password=test < /mnt/azure/azure/test/test.tbl\"
         register: output2

这是错误：
