From 815230943543fe74205e1a23ddbf1e575a30e6e5 Mon Sep 17 00:00:00 2001 From: Awal Garg Date: Tue, 26 Mar 2019 12:18:53 +0530 Subject: [PATCH] Add support for MaraDNS MaraDNS is a lightweight self-hosting DNS server. This patch adds support for adding records to zone files stored on the server in the format expected by MaraDNS. Path to the file should be exported in MARA_ZONE_FILE environment variable. To reload the configuration automatically, the user must provide path to the pid file of duende (the daemonization tool that ships with MaraDNS) in MARA_DUENDE_PID_PATH (--pid argument to duende). --- dnsapi/dns_maradns.sh | 69 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 69 insertions(+) create mode 100755 dnsapi/dns_maradns.sh diff --git a/dnsapi/dns_maradns.sh b/dnsapi/dns_maradns.sh new file mode 100755 index 0000000..4ff6ca2 --- /dev/null +++ b/dnsapi/dns_maradns.sh @@ -0,0 +1,69 @@ +#!/usr/bin/env sh + +#Usage: dns_maradns_add _acme-challenge.www.domain.com "token" +dns_maradns_add() { + fulldomain="$1" + txtvalue="$2" + + MARA_ZONE_FILE="${MARA_ZONE_FILE:-$(_readaccountconf_mutable MARA_ZONE_FILE)}" + MARA_DUENDE_PID_PATH="${MARA_DUENDE_PID_PATH:-$(_readaccountconf_mutable MARA_DUENDE_PID_PATH)}" + + _check_zone_file "$MARA_ZONE_FILE" || return 1 + _check_duende_pid_path "$MARA_DUENDE_PID_PATH" || return 1 + + _saveaccountconf_mutable MARA_ZONE_FILE "$MARA_ZONE_FILE" + _saveaccountconf_mutable MARA_DUENDE_PID_PATH "$MARA_DUENDE_PID_PATH" + + printf "%s.
