aws-py-webserver

Web Server Using Amazon EC2

An example based on the Amazon sample at: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/deploying.applications.html. The example deploys an EC2 instance and opens port 80.

Prerequisites

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

Deploying and running the program

1. Install dependencies (a virtualenv is recommended - see Pulumi Python docs):

   $ pip install -r requirements.txt

2. Create a new stack:

   $ pulumi stack init python-webserver-testing

3. Set the AWS region:

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

4. Create a Python virtualenv, activate it, and install dependencies:

   This installs the dependent packages needed for our Pulumi program.

   $ python3 -m venv venv
   $ source venv/bin/activate
   $ pip3 install -r requirements.txt

5. Run pulumi up to preview and deploy changes:

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

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.

Clean up

To clean up resources, run pulumi destroy and answer the confirmation question at the prompt.
