Custom Domain Names?

[frehner]

Is there a way in SAM to define your Custom Domain Name for an API Gateway endpoint, as well as the base path for it?

[sanathkr]

I am afraid not.. AFAIK CloudFormation hasn't supported APIGW custom domains yet. So SAM does not

[frehner]

@sanathkr thanks for the info. I'll just close this for the time being, then.

@frehner any update on this ?

[frehner]

I’m not working on this at all. You will want to ask one of the maintainers

@frehner thanks, sorry for the confusion.

@sanathkr any update on the ability to define a custom domain name in SAM or CloudFormation ?

I tried @timoschilling snippet, but I get Cannot import certificates for REGIONAL while EDGE is active and I cannot find anything on the internet with this error message.

[shexbeer]

Good question. Please any AWS Guru ?

[deleugpn]

The solution is to set

EndpointConfiguration:
  Types: 
    - REGIONAL

Solid example @timoschilling -- saved me a TON of time.

@timoschilling +1 saved me a tonne of time. Is there an example similar to this in the docs anywhere or would it be worth putting in a PR?
