By default, Puppet will create an SSL certificate for your Puppet master that contains the fully-qualified domain name of the server only. Depending on how your network is configured, it can be useful for the server to be known by other names. In this recipe, we'll make a new certificate for our Puppet master that has multiple DNS names.
Creating certificates with multiple DNS names
Getting ready
Install the Puppet master package if you haven't already done so. You will then need to start the Puppet master service at least once to create a certificate authority (CA).
