aliyun-ddns-updater v1.0.1

Aliyun DDNS Updater

A DDNS client for Aliyun's DNS service. It will look for the device's public IP addresses and update the DNS record with Aliyun's API.

Usage

Install:

npm install -g aliyun-ddns-updater

Then run:

DOMAIN=example.com \
SUB_DOMAIN=ddns \
AK_ID=(accessKeyId) \
AK_SECRET=(accessKeySecret) \
CRON="0 * * * *" \
aliyun-ddns-updater

Or, with Docker:

docker run -d \
    --name aliyun-ddns-updater \
    -e DOMAIN=example.com \
    -e SUB_DOMAIN=ddns \
    -e AK_ID=(accessKeyId) \
    -e AK_SECRET=(accessKeySecret) \
    -e CRON="0 * * * *" \
    --restart unless-stopped \
    hehongbo/aliyun-ddns-updater

The application will look for IP addresses through a public lookup service (by default is https://bot.whatismyipaddress.com), so you don't need to create the container with a host network.

More Options

1. IPv6? \ Yes, with environment variable UPDATE_V6 set to ENABLED, or ONLY if you are using a single v6 stack and updates only AAAA record.
2. Update top-level record? \ Just leave the SUB_DOMAIN environment variable unset. You don't need to pass an @ to update the top-level record.
3. Detecting IP address with a different lookup service? \ Specify it with an IP_LOOKUP_SERVICE environment variable. Note that the application expects a plain address without JSON enclosures or statements like "Your IP address is:", and assumes that the entire response body is the address.
4. One-shot? \ Yes, just remove the CRON environment variable, and it will run only once. That would be helpful if you want to run the application with an external scheduler like Systemd timer. Also, remember to replace the restart policy with something like --rm if you want to run it with Docker before the Docker engine tries to restart it infinitely forever.
5. Timezone? \ Could be set with a TIMEZONE environment. That would affect cron expressions with a specified hour or day. The log output's timestamp will also be affected by this. See Moment Timezone for more information.
