We have a site that needs its letsencrypt certificate renewed. The site uses an unusual web framework and proxy server, but the details are immaterial.
I wrote a bash script that uses Route53 DNS validation because that is the only viable option for this server setup. The script needs more work before it is finished. Check it out here: https://github.com/mslinn/certbot53
BTW, we have ongoing work on AWS using Route53, EC2, CodeCommit, Elastic Transcoder, etc, and we are looking to form a lasting relationship with a remote contractor with strong AWS skills. However, for this first task AWS skills won’t be required, just bash and letsencrypt scripting experience using DNS challenge/response.
If you are interested, please email me ASAP with a brief summary of your relevant skills and experience, and your rate. We need this done right away. This work will of course be 100% remote.
