如何通过--extra-vars将额外的变量传递给ansible作为字典到ansible剧本的列表？

Question

I want to pass variables to my ansible playbook by --extra-vars, and the type of variables is a list of dict like this:

  list1: - { key1: "val1", key2: "val2" } - { key1: "val3", key2: "val4" } 

My playbook is :

 --- - name: main file gather_facts: false hosts: localhost vars: list1: "{{ lists }}" tasks: - name: echo item shell: echo {{ item.key1 }} with_items: list1 

and I try to pass variables like this:

 ansible-playbook build_and_cppcheck.yml -e "lists=[{ "key1": "val1", "key2":"val2" },{ "key1": "val3", "key2":"val4" }]" 

But it doesn't work:

 fatal: [localhost] => with_items expects a list or a set 

Is there any advise?

Just use JSON string syntax: Ansible doc . For example:

$ play.yml

---
- hosts: localhost
  gather_facts: no
  tasks:
    - debug:
        msg: "This is {{ test[0] }}"

    - debug:
        msg: "This is {{ test[1] }}"

$ ansible-playbook play.yml -e '{"test":["1.23.45", "12.12.12"]}'

[3sky@t410 testing]$ ansible-playbook play.yml -e '{"test":["1.23.45", "12.12.12"]}'
 [WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'


PLAY [localhost] ********************************************************************************

TASK [debug] ********************************************************************************
ok: [localhost] => {
    "msg": "This is 1.23.45"
}
