GoDNS

GoDNS is a dynamic DNS (DDNS) tool, it is based on my early open source project: DynDNS.

Now I rewrite DynDNS by Golang and call it GoDNS.

Pre-condition

• GoDNS relies on DNSPod and its API.

• To use GoDNS, you need a domain and hosted on DNSPod.

Build it

Get & build it from source code

• Get source code from Github:

git clone https://github.com/timothyye/godns.git

• Go into the godns directory, get related library and then build it:

cd godns
go get
go build

Config it

• Get config_sample.json from Github.
• Rename it to config.json.
• Configure your domain/sub-domain info, username and password of DNSPod account.
• Configure log file path, max size of log file, max count of log file.
• Configure user id, group id for safety.
• Save it in the same directory of GoDNS, or use -c=your_conf_path command.

Run it as a daemon manually

nohup ./godns &

Run it as a daemon, manage it via Upstart

• Install upstart first
• Copy ./upstart/godns.conf to /etc/init
• Start it as a system service:

sudo start godns

Run it in docker

Now godns supports to run in docker.

• Pull godns image from docker hub:

docker pull timothyye/godns:1.0

• Run godns in container and pass config parameters to it via enviroment variables:

docker run -d --name godns --restart=always \
-e EMAIL=your_dnspod_account \
-e PASSWORD=your_dnspod_password \
-e DOMAIN=your_domain \
-e SUB_DOMAIN=your_sub_domain DOCKER_IMAGE_ID                                                                                              

Enjoy it!
