docker-tinydns

Docker image running tinydns and axfrdns as name server. Uses fefe's ipv6 patches

Name server in a docker container running tinydns and axfrdns. Uses a git repository to periodically pull and update the DNS data.

Variables

• GIT_DNSDATA: URL to pull the dns data from. See example data
• GIT_UPDATE_FREQUENCY: Delay in seconds between each DNS data update

Example usages

Create base axfrdns_tcp file:

cat > axfrdns_tcp <<EOF
# sample line:  1.2.3.4:allow,AXFR="heaven.af.mil/3.2.1.in-addr.arpa"
127.0.0.1:allow
:allow,AXFR=""
EOF

Run tinydns docker container with example data:

docker run -d \
           -e GIT_DNSDATA="https://github.com/andreasfaerber/docker-tinydns-exampledata.git" \
           -e GIT_UPDATE_FREQUENCY=60 \
           -v /docker-tinydns/axfrdns_tcp:/etc/axfrdns/tcp \
           -p 53:53/udp -p 53:53/tcp \
           --name tinydns_example \
           afaerber/docker-tinydns

Run with ssh key authentication for some real world DNS data repository:

• Create a SSH key pair required to pull your DNS data (named ssh_key and ssh_key.pub here)
• Allow the repository to be pulled by that SSH key pair (read-only)
• Change the example GIT_DNSDATA URL to your DNS data repository

docker run -d \
           -e GIT_DNSDATA="https://github.com/andreasfaerber/docker-tinydns-exampledata.git" \
           -e GIT_UPDATE_FREQUENCY=60 \
           -v /docker-tinydns/ssh_key:/root/.ssh/id_rsa \
           -v /docker-tinydns/ssh_key.pub:/root/.ssh/id_rsa.pub \
           -v /docker-tinydns/axfrdns_tcp:/etc/axfrdns/tcp \
           -p 53:53/udp -p 53:53/tcp \
           --name tinydns_example \
           afaerber/docker-tinydns
