A docker wrapper for evil-shrike/ddns-updater to implement auto update DDNS for namecheap.

Create a config.json as following:

{
 "domains": [{
   "service": "namecheap",
   "name": "example.com",
   "hosts": ["@", "www"],
   "settings": {
     "password": "NAMECHEAP_API_KEY"
   }
 }],
 "interval": { "days": 1 }
}

Some parameters need to change:

• name - name of domain, e.g. "example.com" Change the domain
• hosts - an array of host to map to the domain, if you only want naked domain ("example.com") specify "@" or omit field completely.
• settings:password - put your namecheap DDNS token here.
  (Located at Accounts > Domain List > Advanced DNS)

for futher details, please check evil-shrike/ddns-updater.

Run the command and mount the config.json into container.

docker run --restart=always -d --name ddns-updater -v $PWD/config.json:/opt/my-ddns/config.json j796160836/docker-ddns-updater

It will display something like this if no errors.
