do-dns-manager 0.1

A DNS record manager using DigitalOcean as backend, useful for assigning DNS records in a DHCP hook.

A DNS record manager using DigitalOcean as backend, with its own authentication. Best suited when you just need something that changes the DNS, but you don’t want it to have access to other APIs, for example, APIs that can cost you money.

I find this particularly useful for assigning DNS records in a DHCP lease hook. An example hook is included as dnsmasq-hook for dnsmasq users.

Installation

pip install do-dns-manager

Configuration

Create htpasswd.txt somewhere containing lines of username and password pairs separated by :, for example:

spam:password
ham:hunter2

We will call this file $HTPASSWD.

Run the DNS manager as follows:

DIGITAL_OCEAN_API_KEY='(api key)' do-dns-manager --domain=example.com --keyfile=$HTPASSWD --port=8888 --address=127.0.0.1

Change (api key), example.com, $HTPASSWD, 8888 and 127.0.0.1 to fit your situation.

We will use curl examples:

# Add A record for spam.example.com
curl -u 'spam:password' http://127.0.0.1:8888 -d @- <<EOF
{"op": "add", "address": "127.0.0.1", "domain": "spam"}
EOF

# Add AAAA record for spam.example.com
curl -u 'spam:password' http://127.0.0.1:8888 -d @- <<EOF
{"op": "add", "address": "::1", "domain": "spam"}
EOF

# Remove A record for spam.example.com
curl -u 'spam:password' http://127.0.0.1:8888 -d @- <<EOF
{"op": "del", "address": "127.0.0.1", "domain": "spam"}
EOF

# Remove AAAA record for spam.example.com
# Using "address": "::1" instead of "type": "AAAA" also works
curl -u 'spam:password' http://127.0.0.1:8888 -d @- <<EOF
{"op": "del", "type": "AAAA", "domain": "spam"}
EOF
