There are only three tasks needed to create the EFS volumes; as with previous roles, we can use the ansible-galaxy command to create the folder and file structure:
$ ansible-galaxy init roles/efs
Before we add the tasks, we need to add some default variables and a template, so add the following to roles/efs/defaults/main.yml:
efs: wait: "yes" wait_time: "1200"
Now, create a file in roles/efs/templates called targets.j2, which should contain:
---efs_targets:{% for item in subnet_efs_ids %} - subnet_id: "{{ item }}" security_groups: [ "{{ sg_efs.group_id }}" ]{% endfor %}
As you can see, this template is looping over the subnet_efs_ids variable to create a list of subnet IDs and security groups under the variable name efs_targets ...
