acme-redirect: easy to use acmev2 daemon in rust

acme-redirect(1)

A minimal http daemon that answers acme challenges and redirects everything else to https.

A minimal configuration looks like this:

# cat /etc/acme-redirect.d/example.com.conf
[cert]
name = "example.com"
dns_names = [
    "example.com",
    "www.example.com",
]
exec = [
    "systemctl reload nginx",
]

Start the acme-redirect daemon:

systemctl enable --now acme-redirect

Request certificates:

acme-redirect renew

Setup automatic renew:

systemctl enable --now acme-redirect-renew.timer

Your certificate is located here:

/var/lib/acme-redirect/live/example.com/live/fullchain
/var/lib/acme-redirect/live/example.com/live/privkey
