Task 12.2 |Dynamic Inventory in Ansible | Arth |

Task Description

Task — 12.2: Configure the same setup as 12.1 over AWS
using instance over there.

Pre-Requisites

• To use AWS instance as Target node in ansible we need to do some setup.
  Firstly we have to install aws.py

gauravs1303/ansible

• Now we have to transfer the AWS pem key from local system to the ansible VM.
• Third, we need to install python3 for running the ec2.py.

# yum install python3-y

• Third, we need to install boto3 library which is python3 SDK for AWS.

Steps

• First, we have to configure ansible inventory for AWS.
  Here we provide path where we put the aws.py file & pem key in inventory path.
  We also include privilege escalation for root access.

• Now we make both aws.py file & AWS private pem key executable by using below commands:-

# chmod +x ec2.py
# chmod 400 <private_key>.pem

• Now, we need to install boto3 library which is python3 SDK for AWS.

pip install boto3

• The most important step of this task is to set environment variable for authentication

# export AWS_ACCESS_KEY_ID = <ACCESS-KEY>
# export AWS_SECRET_ACCESS_KEY = <SECRET-KEY>
# export AWS_REGION = <AWS-REGION>

Now everything is configured, let’s check that we have everything right or not.

Check

• First to check that ec2,py is running perfectly or not.

# ./ec2.py --list

Output —

• Now we can display the target ec2 nodes.

# ansible all — list-hosts

• To pass tag as hosts in inventory file we use this as example “tag_country_us”.

# Problem I faced in this task

• First of all i faced lots of problem while configuring the dynamic inventry.
• Every time when I start the VM i have to set all three environment variable again.
• Now a suggestion if on list host command, you get wrong credential error then “Power off the Machine” without saving it’s state.
