Adding new subdomains

Getting started

This section will go over how to add new subdomains to the mstacm.org domain using AWS. Subdomains follow the format of *.mstacm.org

Step 1: CloudFront

note: CloudFront is being used to enforce HTTPS across all mstacm domains, if this is not needed then you can skip to step 2. You will most likely want this though :)

Step 1.1

Navigate to the AWS service "CloudFront"

Step 1.2

Click "Create distribution" and follow these steps:

note: there are a lot of fields here, you will only need to mess with the ones mentioned here

• Origin

  • "Origin domain" will be the domain you want your new subdomain to point to

• Viewer

  • For "Viewer protocol policy" select "Redirect HTTP to HTTPS"

• Cache key and origin requests

  • Under "Cache policy" select "CachingOptimized"

• Settings

  • "Alternate domain name (CNAME)" field will be "{your subdomain}.mstacm.org", for example, if the subdomain being added is "security" then the value you would enter is "security.mstacm.org"

  • Under "Custom SSL certificate" choose our ACM Certificate "*.mstacm.org (8ccc6e72-a8db-429d-8a37-c54bdbbfe36d)"

Step 1.3

Done, create the distribution and head to step 2

Step 2: Route53

Step 2.1

Navigate to the AWS service "Route53" -> "Hosted zones" -> "mstacm.org"

Step 2.2

Click "Create record" and follow these steps:

• Enter your new subdomain under "Record name"

• Keep the record type as "A"

• Enable the "Alias" right below the record name field

• Choose "CloudFront distribution" for the "Route traffic to" field

• Select the CloudFront distribution you made earlier

Step 2.3

Done, allow 10 minutes or so for things to start working.
