Loops Ansible数组子集上的循环

我正在编写Ansible playbook，以便在Grafana中自动部署一些仪表盘。我有一个很大的项目列表，这些项目将进入每个仪表板，我如何在数组中循环，但以数组中的4个元素为一组

这是循环

- name: Loop through the topcs to fill in the template with the topic names (replacing the {kafka_topic_placeholder}) and append them to the working file
      shell: sed 's/{kafka_topic_placeholder}/{{ item }}/g' "{{ widget_template_file_path }}" >> "{{ working_file_name }}"
      loop: "{{ kafka_topic_names }}"

但是我想运行以下命令集：

- name: Create the beginning of row
   shell: sed 's/{dashboard_id_placeholder}/{{ dashboard_id }}/g' "{{ dashboard_template_file_part_1 }}" > "{{ final_output_file_name }}"

- name: Add the contents of our working file
   shell: cat "{{ working_file_name }}" >> "{{ final_output_file_name }}"

- name: Add the ending of the row
   shell: sed 's/{overwrite_placeholder}/{{ overwrite_dashboard }}/g' "{{ dashboard_template_file_part_2 }}" >> "{{ final_output_file_name }}"

在这份清单上：

kafka_topic_names:
- topic1
- topic2
...
- topicN

---

因此，我希望在每一行中有4个主题集，从而得到所需的尽可能多的行。我可以让它在一行中处理所有内容，但我不确定如何在循环过程中停止，执行我想要的命令，然后从数组中的同一位置继续循环

您可以像shell脚本一样在一个任务中运行所有命令

- name: Create the beginning of row
  shell: |
    sed 's/{kafka_topic_placeholder}/{{ item }}/g' "{{ widget_template_file_path }}" >> "{{ working_file_name }}"
    sed 's/{dashboard_id_placeholder}/{{ dashboard_id }}/g' "{{ dashboard_template_file_part_1 }}" > "{{ final_output_file_name }}"
    cat "{{ working_file_name }}" >> "{{ final_output_file_name }}"
    sed 's/{overwrite_placeholder}/{{ overwrite_dashboard }}/g' "{{ dashboard_template_file_part_2 }}" >> "{{ final_output_file_name }}"
  loop: "{{ kafka_topic_names }}"
