Domains and certificates


Stacktape allows you to connect your custom domain names to some of your resources (Web Service, HTTP API Gateways, Application Load Balancers and Buckets with CDNs).

Connecting a custom domain to the resource does 2 things:

  • Creates DNS records:
    • If you use your custom domain with a resource, Stacktape automatically creates a DNS record (during deploy) pointing the specified domain name to the resource.
  • Adds TLS certificates
    • If the origin resource (HTTP API Gateway, Application Load Balancer or CDN) uses HTTPS protocol, Stacktape takes care of issuing and attaching correct (free, AWS-managed) certificate to the resource. This means, you do not have to deal with TLS termination as it is handled by the connected resource.
    • If you want to use your own certificates, you can configure customCertificateArns.

To manage a custom domain, it first needs to be added to your AWS account. This means that a hosted zone (collection of records managed together for a given domain) for your domain exists in your AWS account and your domain registrar's name servers are pointing to it. To learn more, refer to Adding a domain guide.

Under the hood

For managing domains and their DNS records, Stacktape uses AWS Route 53. You can also easily buy domain through Route 53 AWS console. SSL/TLS certificates for domains are generated using AWS Certificate Manager(ACM)(free of charge).

Adding domain

The domain needs to be added to your AWS account. You can do that using an interactive domain:add command.

During the process of adding domain:

  • Hosted zone will be created in your AWS account (if not already present). If you registered the domain through your AWS account, the hosted zone is already created.
  • TLS certificates are generated for your domain in the chosen region. If you want to connect the domain to your CDN, the certificates also need to be created in the us-east-1 region ("root" region for the "global" CDN resource).

Migrating to AWS hosted zone

If the domain is managed by a third-party provider (not AWS), the output of the domain:add command will look similarly to the image below.

This means you need to manually change your domain registrar's name server records to point to the created hosted zone. This can be usually easily done in your domain registrar's console UI.

If the domain is in use, you should be careful and refer to this AWS guide before migrating the domain.

If everything went well, the output of the domain:add command will look similarly to the following image

Connecting custom domains to other resources

To connect the domain to a supported resource, use the customDomains property.

To learn more, refer to the docs of these resources:

Using subdomains

Stacktape also allows your to configure subdomains. You can connect your domain to any number of resources.

The subdomain can also be interpolated, for example based on the the specified stage.


type: 'http-api-gateway'
- domainName: $Format('{}', $Stage())
