Deployment

Ready to build Rudolph? Let's go at it!

Getting Ready

You will only need to do this stuff once.

Golang

You will need golang version 1.15+ installed. Go get it from the golang website.

Amazon Web Services

You will need an AWS account handy, as well as an IAM role with sufficient privileges.

Terraform

You will need Terraform v0.14+ installed. We recommend using tfenv.

Registered Domain

You will need a registered DNS domain name for Rudolph's API server.

Purchasing a domain is very easy, simply use AWS's Route 53 service to register a new domain. The exact URL is rarely seen by end users of Santa-Rudolph, so we advise picking any random cheap one to start things up quickly.

Initial Setup

First, you will need to set up a new environment.

Pick an ENV

Pick a new environment name for your deployment.

An environment is a unique instance of Rudolph is associated with a filesystem directory under deployments/environments.

EXPORT your ENV

When working with a specific deployment environment, always make sure your ENV environment variable is set properly.

For example, to direct commands at the deployments/environment/example environment, you would use:

export ENV=example

Create your Terraform Files

You will now create all necessary Terraform configuration files. For convenience, you can set up everything via:

make init-env

You will end up creating:

  • A new directory under deployments/environments
  • A main.tf symlink
  • A variables.tf symlink
  • A versions.tf file
  • A _backend.tf file
  • A config.auto.tfvars.json file
  • (Optional) A _outputs.tf file

You will also need to edit some of these files. A good resource to understanding these configuration files is the example ENV's README.md.

Install Dependencies

Download and install all golang dependencies with:

make deps

First Build and Deploy

You can deploy your entire application now. Luckily, this step is super easy! Do not forget to authenticate with aws-cli.

make deploy

Upon deploying successfully, you will see the sync_base_url output:

Apply complete! Resources: 1 added, 14 changed, 1 destroyed.

Outputs:

sync_base_url = "https://production-rudolph.acme.inc/"

Remember this value, you will need it later when configuring Santa sensors.

Test it Out

Make an HTTP POST request to your new deployment. The request should hit a URL that looks something like:

POST /preflight/AAAAAAAA-BBBB-CCCC-DDDD-EEEEEEEEEEEE
Host: {{PREFIX}}-rudolph.{YOUR_DOMAIN_NAME}
content-type:application/json
accept:*/*
{
  "serial_num": "1234"
}

Future Deployments

Deploying code and making any infrastructure changes is easy:

export ENV=YOURENV
make deploy
