- # Script for sending user defined updates using DO API
- # 2015 Artem Yakimenko <code at temik dot me>
- #
- # activated inside /etc/config/ddns by setting
- #
- # option update_script '/usr/lib/ddns/update_do.sh'
- #
- # the script is parsed (not executed) inside send_update() function
- # of /usr/lib/ddns/dynamic_dns_functions.sh
- # so you can use all available functions and global variables inside this script
- # already defined in dynamic_dns_updater.sh and dynamic_dns_functions.sh
- #
- # It make sence to define the update url ONLY inside this script
- # because it's anyway unique to the update script
- # otherwise it should work with the default scripts
- #
- # Options are passed from /etc/config/ddns:
-
- # Username - the record name DO Zone
- # Password - API Token
- # Domain - the domain managed by DO
- # Parm_opt - The Record ID in the DO API structure
-
- local __URL="https://api.digitalocean.com/v2/domains/[DOMAIN]/records/[RECORD_ID]"
- local __HEADER="Authorization: Bearer [PASSWORD]"
- local __HEADER_CONTENT="Content-Type: application/json"
- local __BODY='{"name":"[NAME]","data": "[IP]"}'
- # inside url we need username and password
-
- [ -z "$domain" ] && write_log 14 "Service section not configured correctly! Missing 'domain'"
- [ -z "$username" ] && write_log 14 "Service section not configured correctly! Missing 'Zone name in Username'"
- [ -z "$password" ] && write_log 14 "Service section not configured correctly! Missing 'password'"
- [ -z "$param_opt" ] && write_log 14 "Service section not configured correctly! Missing 'Zone ID in Optional Parameter'"
-
- # do replaces in URL, header and body:
- __URL=$(echo $__URL | sed -e "s#\[RECORD_ID\]#$param_opt#g" \
- -e "s#\[DOMAIN\]#$domain#g")
- __HEADER=$(echo $__HEADER| sed -e "s#\[PASSWORD\]#$password#g")
- __HEADER_CONTENT=$(echo $__HEADER_CONTENT)
- __BODY=$(echo $__BODY | sed -e "s#\[NAME\]#$username#g" -e "s#\[IP\]#$__IP#g")
-
- #Send PUT request
-
- curl -X PUT -H "$__HEADER_CONTENT" -H "$__HEADER" -d "$__BODY" "$__URL"
-
- write_log 7 "DDNS Provider answered:\n$(cat $DATFILE)"
-
- # analyse provider answers
- # If IP is contained in the returned datastructure - API call was sucessful
- grep -E "$__IP" $DATFILE >/dev/null 2>&1
- return $? # "0" if IP has been changed or no change is needed
