The current certificate for localhost.localstack.cloud and several of its subdomains are stored in server.key.

The file contains both certificate and private key.

Please make sure to conform to the LetsEncrypt Rate Limits.

Most notably, do not rerequest the certficate for the same set of domain names more than 5 times a week, for new domain names more than 50 times a week and no more than 100 names in total per certificate.

• certificate-domains contains a list (newline separated) with all domains the certificate should be valid for. It allows {region} as placeholder, to generate domains for multiple regions.
• certificate-regions contains a list (newline separated) of all regions which will be substituted for the {region} placeholder.

The certificate renewal will happen every time the domain/region list are updated, or every month.
