Lightweight container image for dnstt.

docker build -t dnstt-server .

docker pull ghcr.io/ergolyam/dnstt-docker:latest

DNS_ZONE is required. Configure your DNS records so this zone is delegated to the server running the container.

• With generated key pair:

  docker run --rm -it \
    -p 53:53/udp \
    -e DNS_ZONE=t.example.com \
    -v ./data:/data \
    dnstt-server

• With custom UDP port:

  docker run --rm -it \
    -p 5353:5353/udp \
    -e PORT=5353 \
    -e DNS_ZONE=t.example.com \
    -v ./data:/data \
    dnstt-server

• With custom forward target:

  docker run --rm -it \
    -p 53:53/udp \
    -e DNS_ZONE=t.example.com \
    -e FORWARD=127.0.0.1:1080 \
    -v ./data:/data \
    dnstt-server

The container generates a dnstt key pair on first start when PRIVKEY_FILE does not exist.

• Default generated files:

  ./data/server.key
  ./data/server.pub
  

Use the public key from server.pub when configuring dnstt clients.
