Note: When you attempt any CircleCI exercise, you should comment out the Jobs and Workflows from other exercises. This will ensure that you do not end up creating unnecessary EC2, S3, CloudFront resources in your AWS console.

1. Exercise: Define Ansible Playbook

Files relevant for this exercise are:

├── main2.yml   # Playbook file. You need to rename this to `main.yml`
└── roles
    └── print
        └── tasks
            └── main.yml

2. Exercise: Remote Control Using Ansible

Prerequisite:

• A linux EC2 instance with port 3000 open for the inbound access.
• Public IP address of an EC2 instance in your AWS account.
• A key pair to connect your EC2 instance

Files relevant for this exercise are:

├── inventory.txt
├── main4.yml     # Playbook file
└── roles
    └── setup
        ├── files
        │   └── index.js
        └── tasks
            └── main.yml

3. Exercise: Infrastructure Creation

Files relevant for this exercise are:

└── template.yml            # Change the KeyName property value, as applicable to you
└── .circleci
    └── config.yml          # Look for the create_infrastructure Job

4. Exercise: Config and Deployment

Prerequisite:

• Create an EC2 instance and note it's public IP address
• Add the contents of your PEM file to the SSH keys in your Circle CI account to get the fingerprints

Files relevant for this exercise are:

├── ansible.cfg             
└── .circleci
    └── config.yml          # Look for the configure_infrastructure Job

5. Exercise: Smoke Testing

Files relevant for this exercise are:

└── .circleci
    └── config.yml          # Look for the smoke_test Job

6. Exercise - Rollback

Files relevant for this exercise are:

└── template.yml            # Change the KeyName property value, as applicable to you       
└── .circleci
    └── config.yml          # Look for the create_infrastructure Job and destroy_environment command. 

7. Exercise: Promote to Production

Prerequisite:

• An S3 bucket (say mybucket644752792305) containing a sample index.html file created manually in your AWS console.
• Enable the Static website hosting in that bucket.
• Use the command below to create a CloudFront Distribution

 aws cloudformation deploy \
 --template-file cloudfront.yml \
 --stack-name production-distro \
 --parameter-overrides PipelineID="mybucket644752792305"

Files relevant for this exercise are:

├── bucket.yml          # Creates a new bucket and bucket policy.       
├── cloudfront.yml      # Creates a Cloudfront Distribution that will connect to the existing ^ bucket.
├── error.html
├── index.html  
# Four Jobs: create_and_deploy_front_end, get_last_deployment_id, promote_to_production, and clean_up_old_front_end
