Automatically renew certs and install to destinations
Certmaster automates the process of renewing and installing SSL certificates.
Certmaster uses the excellent go-acme/lego repository to generate certificates and automate DNS validation. They support 100+ providers, which are listed here.
Start with the example config.json and modify it.
To configure DNS providers, create JSON of the form:
{
"provider": "route53",
"AWS_ACCESS_KEY_ID": "ACCESS_KEY_ID",
"AWS_SECRET_ACCESS_KEY": "SECRET_KEY"
}
Here, provider
is the provider name from go-acme/lego
's documentation. The rest of the
fields are configs specific to your DNS provider.
Similarly, you configure destinations with all details required to upload.
To update the certificate, just run:
$ ./certmaster create --config config.json
The Docker file is to use with AWS Lambda. When you invoke the function, you send the same JSON payload as the normal config.
