Fully customizable python script for using DigitalOcean as a DynDNS service.
- Install required packages by running
pip install -r requirements.txt
- Customize config.ini and config.json
- Run dodns.py with Python 3
It is recommended to set up a cronjob to run the script periodically (e.g. every 5 Minutes)
Example config.json file:
{
"bearers": [
{
"key": "b7d03a6947b217efb6f3ec3bd3504582",
"domains": [
{
"name": "example.com",
"dyn_records": [
{
"name": "www",
"host": "raspi"
},
{
"name": "cloud",
"type": "A",
"host": "nas"
}
]
},
{
"name": "me.io",
"dyn_records": [
{
"name": "@",
"type": "TXT",
"data": "current ip: %4",
"host": "raspi"
}
]
}
]
}
]
}
Example config.ini file:
[Dodns]
Hostname=raspi
You have to create an entry in the dyn_records array for each DNS record you want to update dynamically. Each of these entries may contain the following attributes:
name to specify the subdomain.
type to specify the domain record type that is to be updated.
If not present, both the A and the AAAA records will be updated, unless data is set, in which case type will default to TXT.
data can be used to format the data before sending it to DigitalOcean.
Optional for A and AAAA records.
You can use %v4 to insert the IPv4 address and %v6 for the IPv6 address respectively. Use %% to insert a literal %.
host is used as an identifier to determine whether a host is supposed to handle dynamic IP updates for this record.
If not present, any host will update the record.
You can use the host property of dynamic records to specify the name of the host, which is supposed to handle DNS updates for this record.
By default, the value of os.gethostname() is used, but can be changed in the config.ini.
