The rdns-server implements the API interface of Dynamic DNS, its goal is to use a variety of DNS servers such as Route53, CoreDNS etc. Now rdns-server only supports A/TXT records, other record types will be added as soon as possible.

• Default - Route53 - Store the records in the AWS Route53 service and copy them to the database
• Alternative - Etcdv3 - Store the records in the ETCD and query by CoreDNS

• Latest - v0.5.8 - rancher/rdns-server:v0.5.8-rancher-amd64.

make

Different environment variables need to be set for different backend before running.

See here for the environment variables you can set.

export MYSQL_ROOT_PASSWORD="xxx"
export AWS_HOSTED_ZONE_ID="xxx"
export AWS_ACCESS_KEY_ID="xxx"
export AWS_SECRET_ACCESS_KEY="xxx"
export DSN="root:${MYSQL_ROOT_PASSWORD}@tcp(127.0.0.1:3306)/rdns?parseTime=true"
export TTL="10"
./scripts/start route53

This backend will launches the CoreDNS service by default and users no need to run additional CoreDNS.

docker-compose -f deploy/etcdv3/etcd-compose.yaml up -d
export ETCD_ENDPOINTS="http://localhost:2379"
export DOMAIN="lb.rancher.cloud"
./scripts/start etcdv3

If user wants to enables serving zone data from an RFC 1035-style master file. Please put db file to deploy/etcdv3/config directory and add CORE_DNS_DB_FILE & CORE_DNS_DB_ZONE environments before running.

Now supports migration from the v0.4.x data to the new v0.5.x data store (etcdv3, route53).

Please see here for details.
