aws-py-webserver

AWS web server example in Python

An example based on the basic Amazon EC2 Instance sample at: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/deploying.applications.html. The example deploys an EC2 instance and opens port 80. To get the correct Amazon Linux AMI for the instance size and region, a mapping is defined in ami.py.

Prerequisites

1. Install Pulumi
2. Configure Pulumi for AWS
3. Configure Pulumi for Python

Deploying and running the program

1. Login to the Pulumi CLI via pulumi login.

2. Create a new stack:

   $ pulumi stack init python-webserver-testing
   

3. Since Pulumi is in private beta, run the following to install pip packages. For more information, see Using Pulumi PyPI Packages.

   pip install \
       --extra-index-url https://${PULUMI_ACCESS_TOKEN}@pypi.pulumi.com/simple \
       -r requirements.txt
   

4. Set the AWS region:

   $ pulumi config set aws:region us-west-2
   

5. Run pulumi update to preview and deploy changes:

   $ pulumi update
   Previewing stack 'python-webserver-testing'
   Previewing changes:
   ...
   
   Do you want to proceed? yes

6. View the host name and IP address of the instance via stack output:

   $ pulumi stack output
   Current stack outputs (2):
       OUTPUT                                           VALUE
       public_dns                                       ec2-34-217-176-141.us-west-2.compute.amazonaws.com
       public_ip                                        34.217.176.141
   

7. Verify that the EC2 instance exists, by either using the AWS Console or running aws ec2 describe-instances.

8. Clean up resources by running pulumi destroy and answering the confirmation question at the prompt.
