AWS Request Domain Renewal

Occassionally, AWS requires validation of your domain via email message. Here’s the command to send a request.

aws acm resend-validation-email \
--certificate-arn arn:aws:acm:us-east-1:xxxxxxxxxxxx:certificate/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx \
--domain yourdomain.com \
--validation-domain yourdomain.com
 
aws acm resend-validation-email \
--certificate-arn arn:aws:acm:us-east-1:xxxxxxxxxxxx:certificate/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx \
--domain www.yourdomain.com \
--validation-domain yourdomain.com

You will need acm:ResendValidationEmail permission to run the command.

GCP Create SSL Certificate

gcloud compute ssl-certificates create certificate-name \
--description="ssl cert for domain-name.com" \
--domains=domain-name.com \
--certificate=certificate-file \
--private-key=private-key \
--region=us-central1-c \
--global

Adding Domains in Certbot

You can register multiple domains to a single SSL certificate. This is particularly useful if you are hosting multiple domains on one server. This command adds more domains to your existing certificate.

certbot --expand -d existing.com -d newdomain1.com -d newdomain2.com

Check if the domains were added.

certbot certificates

Certbot certificates are valid for 90 days, but they automatically renew themselves if expiration is less than 30 days. If you need to renew manually for some odd reason, you can run this command. You can also perform a dry-run before renewing.

certbot renew
certbot renew --dry-run
