Certbot AWS Renewals

Here are the instructions for renewing Certbot SSL certificates in AWS Certificate Manager. Certbot provides SSL certificates for free for 60 days and are auto-renewed before they expire. If you are using Certbot SSL certificates with CloudFront, you will need to reimport them to AWS Certificate Manager before expiration.

  1. Get the latest SSL certificate by running “certbot certificates.”
  2. Reimport the certificate in 3 parts.
    • Certificate Body – the root or top portion of the full chain
    • Certificate Private key – the private key
    • Certificate chain – the entire full chain containing multiple certificates
  3. Click Save. Check expiration.

You’ll need to update the certificate before the next expiration date.

Certificate Management Import

My previous post lightly talked about about adding SSL certificates via the AWS Console. This post talks about adding your own SSL certificate to Certificate Manager via the AWS CLI. The CLI which makes it super simple to manage. It also allows for automation as well. 

aws acm import-certificate \
--certificate file://Certificate.pem \
--certificate-chain file://CertificateChain.pem \
--private-key file://PrivateKey.pem

If successful, it will return ARN or Amazon Resource Name.
