HAProxy SSL
Contents
Generation
haproxy(1) uses PEM-formatted certificates for encryption. This is simply the certificate and private key concatenated.
The following script can be used by either a cron job or set as a certbot(1) post-installation hook.
domain="example.com" dir="/etc/letsencrypt/live/${domain}" cat "${dir}/fullchain.pem" "${dir}/privkey.pem" > "${dir}/${domain}.pem"
