ansans-错误！任务中未检测到任何操作

Question

来自下面的剧本：

---
- name: Todobackend deployment playbook
  hosts: localhost
  connection: local
  gather_facts: no
  vars_files:
    - secrets.yml
  environment:
    AWS_DEFAULT_REGION: "{{ lookup('env', 'AWS_DEFAULT_VERSION') | default('us-west-2', true) }}"
  tasks:
    - include: tasks/create_stack.yml
    - include: tasks/deploy_app.yml

下面是应用程序部署任务模板（tasks/deploy.yml）：

---
- name: set task definition facts
  set_fact:
    todobackend_task_def_arn:
      "{{ cf_stack.stack_outputs.TodobackendTaskDefinition | regex_replace('^(.*):[\d]*$', '\1') }}"
    todobackend_adhoc_task_def_arn:
      "{{ cf_stack.stack_outputs.TodobackendAdhocTaskDefinition | regex_replace('^(.*):[\d]*$', '\1') }}"

- name: update task definition

    - "{{ todobackend_adhoc_task_def_arn }}"
  when: image_tag is defined

- name: run migrations

          - "--noinput"
  register: migration_task
  when: ('migrate' in ecs_tasks | default([]))

    when: debug is defined
  - name: "fail if migration task failed"
    fail: msg="One or more migration tasks exited with non-zero exit code"
    with_items: "{{ migration_task.task | default([])}}"
    when: item.containers[0].exitCode != 0
  when: migration_task is defined

- name: run collectstatic

    operation: run
    cluster: "{{ cf_stack.stack_outputs.EcsCluster }}"

    overrides:

    when: item.containers[0].exitCode != 0
  when: collectstatic_task is defined

- name: configure ecs service
  aws_ecs_service:
    state: update
    name: "{{ cf_stack.stack_outputs.TodobackendService }}"
    cluster: "{{ cf_stack.stack_outputs.EcsCluster }}"
    task_definition: "{{ todobackend_task_def_arn }}"
    desired_count: "{{ instance_count | default(1) }}"
    deployment_config:
      minimumHealthyPercent: 50
      maximumPercent: 200
  register: configure_ecs_service
  when: stack_config is defined

- debug: msg={{ configure_ecs_service }}
  when: configure_ecs_service is defined  and debug is defined

- name: deploy service update

  register: update_ecs_service
  when: image_tag is defined
- debug: msg={{ update_ecs_service }}
  when: update_ecs_service is defined and debug is defined

以下命令出现错误：

$ ansible-playbook site.yml --ask-vault-pass -e '{"ecs_tasks":["migrate","collectstatic"],"stack_config":"true","debug":"true"}'
Vault password: 
 [WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'

ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to have been in '/home/user/../tasks/deploy_app.yml': line 9, column 3, but may be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


- name: update task definition
  ^ here

文件夹结构：

$ ls -R

group_vars  library  secrets.yml  site.retry  site.yml  tasks  templates

./group_vars:
all

./library:
aws_ecs_service.py  aws_ecs_taskdefinition.py  aws_ecs_task.py

./tasks:

here是完整的代码

如何解决“更新任务定义”任务中的此错误？
