Wildcard cert for unlimited subdomains
Running 30 sites on subdomains off one box. One wildcard cert covers them all:
— apt install certbot python3-certbot-dns-cloudflare -y
— Drop your Cloudflare API token in ~/.secrets/cf.ini, chmod 600
— certbot certonly --dns-cloudflare --dns-cloudflare-credentials ~/.secrets/cf.ini -d '*.mydomain.com' -d mydomain.com
— Point every nginx server block at the same /etc/letsencrypt/live/mydomain.com/ files
DNS challenge = no port 80 juggling, renews on cron silently. Try it tonight.
