Zero-install certbot run (ovh-dns plugin)

certbot.sh

#!/usr/bin/env bash

sudo podman run -it --rm --name certbot \
  -v "/etc/letsencrypt:/etc/letsencrypt" \
  -v "/var/lib/letsencrypt:/var/lib/letsencrypt" \
  -v ".:/tmp/secrets" \
  docker.io/certbot/dns-ovh certonly \
  --dns-ovh-credentials=/tmp/secrets/ovh-certbot.conf

# Use docker.io/certbot/dns-YOURHOSTINGPROVIDER
# Or docker.io/certbot/certbot for non-DNS

# Caveats:
# - only supports "certonly"
# - does not set a renewal cronjob automatically
