Most (almost all) users do not need to modify Certbot configs. CapRover automatically manages it for you. You can skip this page.
Normally, the directory
/captain/data/letsencrypt/etc should contain the volume used by Certbot,
to configure Certbot, add a
cli.ini file in this directory:
$ cd /captain/data/letsencrypt/etc/
$ nano cli.ini
Configure the right things
We will take as an example ZeroSSL's ACME server to guide you over the steps needed to make Certbot work correctly with it,
first (at least for ZeroSSL, you need to get EAB credentials which are here) we add our email and we tell Certbot to accept the TOS of the service:
email = firstname.lastname@example.org
agree-tos = true
then we add the server (and if needed the EAB credentials):
server = https://acme.zerossl.com/v2/DV90 # (change it with your ACME server)
eab-kid = some-short-string
eab-hmac-key = a-big-key
Then to apply our changes we need to update Certbot's service:
$ docker service update captain-certbot
And you're done !
Remember to add a CAA record in your DNS to avoid any problem when generating SSL certs
for example, ZeroSSL need you to have:
<your domain>. 3600 IN CAA 0 issue "sectigo.com"
<your domain>. 3600 IN CAA 0 issuewild "sectigo.com"
