问题
I am using ansible to create instance in different AZ , i am facing two issues here:
- I need to create 3 instances in AZ , but the below play creates 6 instances such that 3 instances in AZ-a and 3 in AZ-b
- I am trying to tag these instances as well, using a sequence as they are being created, but i am not able to pass/traverse the json returned.
Here are the plays:
---
- name: Create ES Master Node instances
ec2:
key_name: "{{ aws_key_name }}"
instance_type: "{{ aws_instance_type }}"
image: "{{ aws_ami }}"
wait: yes
wait_timeout: 500
count: "{{ master_instance_count }}"
instance_tags:
Name: "{{ master_tag_name }}"
volumes:
- device_name: /dev/sda1
volume_type: gp2
volume_size: 100
vpc_subnet_id: "{{ subnet_ids[item] }}"
region: "{{ aws_region }}"
group: "{{ aws_sec_group_name }}"
with_items:
- a
- b
register: ec2_details
- name: Generate Sequence ID for tagging
debug: msg="{{ item }}"
with_sequence: start="{{ startindex }}" end="{{ master_instance_count }}" format=%02d
register: sequence
- name: Debug the variable name
debug:
var: ec2_details
#msg={{ ec2_details | type_debug }}
- name: Tag Created instance as Masters
ec2_tag:
region: "{{ aws_region }}"
resource: "{{ item.0.id }}"
tags:
Name: "{{ master_tag_name }}-{{ item.1.msg }}"
with_together:
- "{{ ec2_details.results.instance_ids }}"
- "{{ sequence.results }}"
- name: Add Instances to local inventory file
local_action:
lineinfile path="~/ansible-environments/hosts"
insertafter="\[esmaster\]"
line="{{ item.private_ip }}"
state="present"
with_items: "{{ ec2_details.results.instances }}"
I am not sure how is issue 1 happening and how to solve, and for the 2nd i need help in traversing the result so that i can tag and create inventory in a file.

I don't have good knowledge about AWS as per your output of the playbook and the playbook you posted.
"invocation": {
"module_args": {
"assign_public_ip": false,
"aws_access_key": null,
"aws_secret_key": null,
"count": 3,
"count_tag": null,
"ebs_optimized": false,
"ec2_url": null,
"exact_count": null,
"group": [
"mayassar-es-external",
"elasticsearch-mayassar-production",
"Test_nishant"
],
Here the count is 3, so it creates three instances in both the regions a and b
If you want to traverse output you can use the following method
