Step 4: Create a file named aws_ec2.yaml in the inventory directory and vi into the file. # touch aws_ec2.yaml # sudo vi aws_ec2.yaml Copy the following configuration to the file. If you are running an ansible server outside the AWS environment, replace add your AWS access key and secret to the config file. --plugin: aws_ec2 aws_access_key: XXXXXXX aws_secret_key: XXXXXXX keyed_groups: - key: tags prefix: tag HOW TO GENERATE ACCESS AND SECRETE KEY FROM AWS ACCOUNT AND CONNECT TO OUR CLI a. Go to your aws account, click on the top tight profile section. b. Click on security credentials. c. Under access key, click on create access key and retrieve the details. Access key: AKIAUNPLKPRVE5G5APO Secret key: VRfPLEhHy6CR4X+ui7Z/WF4nKDUH6+N7L/lQg17 TO CONNECT AWS CLOUD ACCOUNT TO OUR CLI DO THE FOLLOWING Run the following command and input the access and secret key: # aws configure Check to confirm if your key is saved in the directory ~/.aws. a. # cd ~/.aws # ls c. # cat credentials b. Ansible ssh configuration 1. Clone the ansible-configuration repo [ https://github.com/Lion-Technology-Solutions/ansibleconfiguration-management.git ] . 2. In your local CLI switch directory to /etc/ansible and; 3. Remove the existing ansible.cfg file from /etc/ansible using the commands below; Commands and steps a. cd /etc/ansible b. sudo rm -rf ansible.cfg 4. cd ~ to go back to your home directory and Access the repo that was cloned above; # cd ansible-configuration-management 5.
