dnsmasq

We use dnsmasq as a lightweight DNS server for discovery of fixed services within our infrastructure. e.g. Eureka

Provided here is a minimal docker image designed to configure itself from a mapped directory of .conf files.

How to use

Starting a container from this image is simple. We run it directly on the host's network stack so the host can act as a DNS for other services in the network.

docker run --name dnsmasq --cap-add=NET_ADMIN --net=host -v /etc/dnsmasq:/etc/dnsmasq storytel/dnsmasq

We can then add multiple .conf files to the /etc/dnsmasq folder to provide layered configuration. This layering is useful to allow multiple services to add their own configuration files.

# 0.base.conf

domain-needed
bogus-priv
no-hosts
keep-in-foreground
no-resolv
