在Ansible任务中作为YAML键的值

我无法弄清楚如何传递一个键值对的字典/散列图作为一个可选任务的值。

默认选项：

# roles/ec2/defaults/main.yml ec2: key_name: "{{ key_name }}" instance_type: m3.medium image: ami-xxxx group_id: sg-xxxxx vpc_subnet_id: subnet-xxxxx region: us-east-1 wait: yes instance_tags: Name: "{{ env_name }}-{{ group_name }}-{{ ansible_date_time.epoch }}" Type: "{{ env_name }}-{{ group_name }}-{{ ansible_date_time.epoch }}" 

尝试1

 # roles/ec2/tasks/main.yml - name: launch single instance ec2: "{{ ec2 }}" register: instance
