Question

In salt states, we use "grains.host" to get the host details. How do we get the AWS EC2 availability zone name using salt grains?

To get the hostname I give the below:

{%- if 'aws-dev-01' in grains.host %}
{%- set device = '.....' %}

To get the EC2 AZ name, are the below lines correct?

{%- if 'us-east-1a' in grains.availability_zone %}
{%- set device = '.....' %}

Answer 1

That is correct, but you need to set metadata_server_grains: true in the minion config first.

In addition, only IMDSv1 is currently supported.
