I needed a Dynamic DNS service and decided to use our API to do it. Here is the script for anyone who might need to do this too.
# Opalstack API settings
api_token = '123456789' # Replace with your Opalstack API token
# Domain settings
domain_name = 'example.com' # Replace with your domain name
import requests
import opalstack
# Initialize Opalstack API
opal = opalstack.Api(token=api_token)
def get_wan_ip():
"""
Get the current WAN IP using a public API.
"""
response = requests.get('https://api.ipify.org?format=json')
return response.json()['ip']
def check_domain_in_list(domain_id, records_list):
"""
Check if the given domain ID exists in the list of records.
:param domain_id: The domain ID to search for.
:param records_list: The list of records, each a dictionary.
:return: True if the domain ID is found, False otherwise.
"""
for record in records_list:
if record['domain'] == domain_id:
return record
return False
def update_a_record(domain, ip_address):
"""
Update the A record for the specified domain with the provided IP address.
"""
domains = opal.domains.list_all()
# Enhanced domain matching logic
domain_id = None
for d in domains:
full_domain = d['name'].strip()
if full_domain == domain.strip():
domain_id = d['id']
break
if not domain_id:
print(f"Domain '{domain}' not found.")
return
records = opal.dnsrecords.list_all()
a_record = check_domain_in_list(domain_id, records)
if not a_record:
print(f"No A record found for '{domain}'. Creating one.")
opal.dnsrecords.create(domain_id, 'A', ip_address, 600)
print(f"A record created for IP {ip_address}")
else:
print(a_record['id'], ip_address)
opal.dnsrecords.update_one({'id':a_record['id'], 'type':'A', 'content':ip_address, 'ttl':600})
print(f"A record updated to IP {ip_address}")
# Main execution
current_ip = get_wan_ip()
update_a_record(domain_name, current_ip)
