Hi Everyone ,

I am very new to Ansible and currently struggling for getting this done ,

I wrote a ec2 role which launch ec2 instances based on count provided by vars , role is working fine and I have also used tags , A tag with Name is also added while launch , My requirement is I want to add some sequence along with my tags , but I am not able to achieve same .

I tried some stackoverflow solutions but it didnt work ,

My launch task in ec2 role is

- name: Launch EC2 instances

ec2:

key\_name: “{{ key\_pair }}”

instance\_type: “{{ instance\_type }}”

image: “{{ ami\_id }}”

region: “{{ region }}”

wait: yes

group\_id: “{{ security\_group\_id }}”

count: “{{ instance\_count }}”

vpc\_subnet\_id: “{{ subnet\_id }}”

assign\_public\_ip: no

termination\_protection: no

register: ec2

- name: Generate Sequence Number

with\_sequence:

start={{ start\_index }}

end={{ instance\_count }}

register: sequence

- name: tag instances

ec2\_tag:

region: “{{ region }}”

resource: “{{ item.0.id }}”

tags:

Name: “{{tag\_key\_vals.Name}}-{{ item.1.msg }}”

with\_together:

- “{{ ec2.instances }}”

- “{{ sequence.results }}”

But again this is not working .

Please suggest some way to do same.

Regards

Arvind

I haven't used ec2 modules and can't comment on that, but I'll make some comments on the Ansible part.

This task will not work, with\_sequence is not a module but a directive to the task.  
So this is not at valid task since it is missing a module.

Instead of sequence.results you can replace that with the range[1] filter

- "{{ range(start\_index, instance\_count) }}"
