A new acme process is created that communicates with the acme servers.
This process does not hold any of your private keys (no account keys,
no domain keys etc).
Whenever the acme process requires a signed payload it will ask the keymgr
process to do the signing with the relevant keys.
This process is also sandboxed with pledge+unveil on OpenBSD and seccomp
syscall filtering on Linux.
The implementation only supports the tls-alpn-01 challenge. This means that
you do not need to open additional ports on your machine.
http-01 and dns-01 are currently not supported (no wildcard support).
A new configuration option "acme_provider" is available and can be set
to the acme server its directory. By default this will point to the
live letsencrypt environment:
https://acme-v02.api.letsencrypt.org/directory
The acme process can be controlled via the following config options:
- acme_root (where the acme process will chroot/chdir into).
- acme_runas (the user the acme process will run as).
If none are set, the values from 'root' and 'runas' are taken.
If you want to turn on acme for domains you do it as follows:
domain kore.io {
acme yes
}
You do not need to specify certkey/certfile anymore, if they are present
still
they will be overwritten by the acme system.
The keymgr will store all certificates and keys under its root
(keymgr_root), the account key is stored as "/account-key.pem" and all
obtained certificates go under "certificates/<domain>/fullchain.pem" while
keys go under "certificates/<domain>/key.pem".
Kore will automatically renew certificates if they will expire in 7 days
or less.
