+# Day 72: Infrastructure as Code with Pulumi
+
+Welcome to day 72 of the 2024 edition of 90 Days of DevOps!
+
+Today's session is titled "Infrastructure as Code with Pulumi", and it is led by Scott Lowe.
+
+## Video
+
+A link to the video will be inserted once the video is published.
+
+## Additional Notes
+
+Code for this session, as well as a PDF version of the slides, is available from [the companion repository](https://github.com/scottslowe/2024-90dod-iac-pulumi).
+
+To use the example code, you will need the following:
+
+* The AWS CLI installed and configured for an AWS account (Pulumi doesn't rely on the AWS CLI, but it uses the configuration for connecting to AWS)
+* An SSH key pair defined in your AWS account and in your desired region
+* The `pulumi` CLI tool installed and logged into a backend (see the slides for more information on Pulumi backends; using [Pulumi Cloud](https://app.pulumi.com) is the easiest and fastest way to get started)
+* NodeJS installed
+* The `git` CLI tool installed
+* _(Optional)_ SSH installed on your system, if you want to be able to connect to the instance provisioned by the Pulumi program
+
+Follow these instructions to run this Pulumi program:
+
+1. Use `git clone` to clone [the companion repository](https://github.com/scottslowe/2024-90dod-iac-pulumi) to your local system.
+1. Change into the directory where the repository was cloned.
+1. Use `pulumi stack init <name>` to create a new Pulumi stack named `<name>`.
+1. Run `npm install` to install the dependencies for the Pulumi program.
+1. Run `pulumi config set aws:region <region>` to specify the AWS region where the resources should be created.
+1. Run `pulumi config set keypair <keypair-name>` to specify the name of an existing AWS key pair that can be used for SSH access to an EC2 instance.
+1. _(Optional)_ Set the desired VPC CIDR block with `pulumi config set vpcNetworkCidr <cidr>`.
+1. _(Optional)_ Set the instance type with `pulumi config set <instance-type>`.
+1. Run `pulumi up` to instantiate the infrastructure.
+1. After the stack has finished provisioning, run `pulumi stack output` to get the IP address of the Flatcar Container Linux instance that was created. You can SSH into this instance to run Docker commands and verify that Pulumi launched a Docker container on this instance.
+1. When you're finished, run `pulumi destroy` to tear down all the AWS resources.
+
+Enjoy!
