Hello guys
I created the following structure:
```
amis:
us-east-1:
amazonlinux:
owner_id: "137112412989"
x86_64: "ami-01bc990364452ab3e"
arm64: "ami-0900a8f768a21540a"
user: "ec2-user"
ubuntu:
owner_id: "099720109477"
x86_64: "ami-0fc5d935ebf8bc3bc" # Ubuntu 22
arm64: "ami-016485166ec7fa705" #
user: "ubuntu"
```
and I have a json file that I fill in to raise an ec2 instance:
```json
{
"aws_region":"us-east-1",
"architecture":"arm64",
"os_version":"ubuntu",
"instance_name":"test6",
"domain":"example.corp",
"subnet":"SUBNET-PUB-A",
"instance_type":"t4g.micro",
"security_groups": [ "sg-xxxxxx", "sg-yyyyyyyy"],
"aws_role":"default-role",
"root_volume_size":20,
"ebs_swap_size": 4,
"keyname": "ssh-key",
"ebs_type": "gp3",
"backup": "no",
"boxenv":"DEV"
}
```
And I read this json and create the variables with the tasks:
```
- name: Read json configuration
shell: cat config-ec2-launch.json
register: result
- name: save the Json data to a Variable as a Fact
set_fact:
jsondata: "{{ result.stdout | from_json }}"
- name: Variable | Get aws_region variable
set_fact:
aws_region: "{{ jsondata | json_query(jmesquery) }}"
vars:
jmesquery: 'aws_region'
- name: Variable | Get architecture variable
set_fact:
architecture: "{{ jsondata | json_query(jmesquery) }}"
vars:
jmesquery: 'architecture'
- name: Variable | Get os_version variable
set_fact:
os_version: "{{ jsondata | json_query(jmesquery) }}"
vars:
jmesquery: 'os_version'
```
and created the tasks right away:
```
- name: AWS Ec2 Instance | Create the EC2 instance
ec2_instance:
state: started # started state=running + waits for EC2 status
checks to report OK if wait=true
image_id: "{{ newest_ami }}"
name: "{{ instance_name }}"
detailed_monitoring: false
metadata_options:
http_tokens: required
instance_type: "{{ instance_type }}"
region: "{{ aws_region }}"
vpc_subnet_id: "{{ subnet_facts.subnets.0.id }}"
instance_initiated_shutdown_behavior: stop
instance_role: "{{ aws_roles[aws_role] }}"
volumes:
- device_name: "{{ name_device_root_ami.images.0.root_device_name
}}"
ebs:
volume_type: gp3
volume_size: "{{ root_volume_size }}"
delete_on_termination: true
security_groups: "{{ security_groups }}"
tags:
Name: "{{ instance_name }}"
Domain: "{{ domain }}"
Backup: "{{ backup }}"
BOXENV: "{{ boxenv }}"
key_name: "{{ aws_key_names[keyname] }}"
wait: yes
register: ec2
- name: AWS Ec2 ebs | Add volume to swap
amazon.aws.ec2_vol:
instance: "{{ ec2.instances[0].instance_id }}"
volume_size: "{{ ebs_swap_size }}"
volume_type: "{{ ebs_type }}"
delete_on_termination: True
device_name: "/dev/sdf"
region: '{{ aws_region }}'
tags:
Name: "{{ instance_name }}:swap"
BOXENV: "{{ boxenv }}"
- name: Swap | List all devices on {{ instance_name }}
vars:
ansible_ssh_user: "{{ amis[ aws_region ][ os_version ].user }}"
ansible.builtin.shell: echo "{{ aws_region }} {{
ec2.instances.0.network_interfaces.0.private_ip_address }}"
register: devices_host
delegate_to: "{{
ec2.instances.0.network_interfaces.0.private_ip_address }}"
args:
executable: /bin/bash
```
But when I run it, it displays the error below
```
FAILED! => {"msg": "'aws_region' is undefined"}
```
If I comment the line `ansible_ssh_user: "{{ amis[ aws_region ][ os_version
].user }}"` it displays the contents of the aws_region variable. Any idea
where I'm going wrong?
Thanks
