ec2.instances.public_ip is not working

instances is an array of dicts here.

You'll need a 0 in there to access the first element of that list:

ec2.instances.0.public_ip_address

Thank you sebastian for quick reply

unfortunately that didn’t work

here the part that i am running

  • name: “gather instance facts”
    ec2_instance_facts:
    instance_ids: i-xxxxxx
    region: “{{ region }}”
    delegate_to: localhost
    when: ec2_instance_prov == ‘no’
    register: ec2
    tags:
  • gather-facts
  • provision-ec2
  • debug:
    var: ec2.instances.0.public_ip_address
    tags:
  • gather-facts

after i run this i see no output

PLAY [Provision an EC2 Instance] *************************************************************************************************************************************************************************************************************

TASK [gather instance facts] *****************************************************************************************************************************************************************************************************************
ok: [localhost → localhost]

TASK [debug] *********************************************************************************************************************************************************************************************************************************
ok: [localhost] => {
“ec2.instances.0.public_ip_address”: “VARIABLE IS NOT DEFINED!”
}

PLAY RECAP ***********************************************************************************************************************************************************************************************************************************

Hi,

in this case verify that

- debug:
    var: ec2

works first.

Then try:

- debug:
    var: ec2.instances

Afterwards:

- debug:
    var: ec2.instances.0

So basically you try to build the path to the value you want. If one
fails, please post the output of the last succeeding debug.

Hello Sebastian

Thank you for the help i was able to get it working

i have another problem how can i get only the arn value but not complete output saved in to variable

TASK [debug] ****************************************************************************************************************************************************************************************************************************

ok: [localhost] => {

“template_arn.results.0.stdout_lines[1]”: " "assessmentTemplateArn": "arn:aws:inspector:us-west-2:024283424342:target/0-Rrtw16WK/template/0-5KIIPQREcC""

i want to print only arn:aws:inspector:us-west-2:024283424342:target/0-Rrtw16WK/template/0-5KIIPQREcC\ i dont want “”““assessmentTemplateArn””“” to be saved to my variable
Can anyone please help

Please send a new message for that and don't pollute this thread for
(judging by the error) an unrelated issue.
Be sure to add enough information though (tasks/playbooks).

thx!
