Automatic renew an existing certificate

All existing ACME certificates are automatically renewed 30 days before their expiration. The default check timing is 00:00 UTC.

If you need to change the time zone, use WEBSITE_TIME_ZONE to set the time zone.

How much does Azure cost?

The cost per month of Azure resources required to use Acmebot is approximately as follows. In addition, there is a separate fee for Key Vault certificates.

  • Azure Functions = <$0.01
  • Storage Account = $0.1~$0.2
  • Application Insights = $0.01~$0.02

If you have a very large number of certificates to manage, or if you use the management screen frequently, the amount charged will vary.

Issuing a wildcard certificate or a certificate for Linux

Because Azure DNS is required to issue wildcard certificates or certificates for Linux, assign the role of DNS Zone Contributor in the resource group containing the target DNS zone.

IAM settings

To issue certificates for "App Service on Linux" and "Web App for Container", Azure DNS is always required.

Deploying a new version

The application is automatically updated so that you are always up to date with the latest version. If you explicitly need to deploy the latest version, restart the Azure Function.

In case you want to use your own web.config

You can prevent Acmebot from creating a web.config by creating your own web.config and configured files in the site/.well-known directory.
