Traefik cannot fetch Acme certificate with Route 53 - docker

Question

I'm having a little trouble configuring Traefik and ACME certs with AWS Route 53. I tried both http and dns challenges with no avail. It keeps getting this error: acme: error presenting token: route53: failed to determine hosted zone ID: NoCredentialProviders: no valid providers in chain
what am I doing wrong here? Thanks in advance.

Answer 1

The HTTP challenge requires that port 80 be accessible on the Internet.
For the DNS challenge you need to define the credentials:
AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, [AWS_REGION], [AWS_HOSTED_ZONE_ID] or a configured user/instance IAM profile.
