This project creates an docker image which request or renew a certificate whether it exist or not.
To obtain a certificate you have to run the Image with following parameters:
docker run -e DOMAINS="example.com" -e MAIL=admin@example.com vlli/docker-certbot-request-renew:route53
At the current situation you must use an IAM Role for your EC2 Instance which have the permission to create DNS entries.
Every certificate which is obtained by the script will also be a wildcard certificate. This behaviour is not optional.
