Update DNS

Currently, Opta does not support multiple domains (except subdomains) per environment, although that may change based on user demand. In order for a user to change the domain tied to their environment, they would need to remove their current dns module, and then add a new one after applying.

Take for example, if we had the current running environment:

name: staging
org_name: my-org
providers:
  aws:
    region: us-east-1
    account_id: XXXX # Your 12 digit AWS account id
modules:
  - type: base
  - type: dns
    domain: staging.startup.com
  - type: k8s-cluster
  - type: k8s-base

Supposed we wished to change the domain from staging.startup.com to otherdomain.dev. First we would remove the dns module:

name: staging
org_name: my-org
providers:
  aws:
    region: us-east-1
    account_id: XXXX
modules:
  - type: base
  # dns module was removed
  - type: k8s-cluster
  - type: k8s-base

Next, run opta apply the new yaml and see that the dns resources have been destroyed. Note that your site will be temporarily offline after this step and before the next steps are completed. Afterwards we would add the new dns module entry with the new domain like so:

name: staging
org_name: my-org
providers:
  aws:
    region: us-east-1
    account_id: XXXX # Your 12 digit AWS account id
modules:
  - type: base
  - type: dns
    domain: otherdomain.dev
  - type: k8s-cluster
  - type: k8s-base

We would opta apply like before and we would now have the new domain. Depending on your set up there may be some additional steps required:

What if I had the domain delegated already?

That’s fine, the removal of the old domain can proceed with no changes but at the end you would need to do the delegation steps for the new domain.

What if I had deployed some services whose public_uri was based off {parent.domain}?

You would need to do a new apply for each of those services as they would not have gotten the memo of the new domain. You can use the same image, and opta yaml for the service as before– zero change necessary, all we need is the new apply.
