試圖過濾一個with_item結果是可靠的

Question

何傢伙。我試圖找到一個有效的答案，但失敗了; 我們正在加載docker image sinto a vm。我們希望調出每個列表的.actions，而不用硬編碼響應列表。 有誰知道如何？

這裏是我們到目前爲止的代碼：

--- 
- name: 'Debbug images to pull' 
    debug: 
    var: required_images 

- name: 'Pull docker images so that we have them pre-loaded' 
    docker_image: 
    name: "{{ item.image_name }}:{{ item.image_version }}" 
    state: 'present' 
    with_items: "{{ required_images }}" 
    register: docker_pull_output 

- name: 'Confirm images pulled attempt a - this looks righ tbut has the array length hard coded' 
    debug: 
    var: item 
    verbosity: 2 
    with_items: 
    - "{{ docker_pull_output.results[0].actions }}" 
    - "{{ docker_pull_output.results[1].actions }}" 
    - "{{ docker_pull_output.results[2].actions }}" 
    - "{{ docker_pull_output.results[3].actions }}" 
    - "{{ docker_pull_output.results[4].actions }}" 

- name: 'Confirm images pulled attempt b - this spams us with the full item, not just the .action property' 
    debug: 
    var: item.actions 
    verbosity: 2 
    with_items: "{{ docker_pull_output.results }}"

爲了讓您的拉任務的所有操作的列表，你可以使用JMESPath：

- debug: 
    msg: "{{ docker_pull_output.results | json_query('[].actions[]') }}"
