Let's Encryptが2018年1月末頃にはWildcard証明書を発行する予定!と言っていたのがやっとリリースされました!(わーぱちぱち)
せっかくなので発行してみました。いまのところ、コマンドラインから--server
とv02エンドポイントを明示する必要があるそうです。
途中さらっと流してますが、Wildcard証明書はDNS-01でドメインを検証しないといけないので、Certbotの指示に従ってDNSのTXTレコードを設定しています。 このドメインはConoHaでホストされているのでAPIで設定することもできますが、今回はWebから手動で変更しました。

これをNginxに設定して…ってアクセスするとサブドメイン付きのドメインしか指定されてないのでサブドメインのついてないところにアクセスするとエラー。なのでSANで作り直しました。
