SeaDNS is a lightweight service which makes using a development-environment TLD extremely easy, on all platforms. It does this by providing a DNS server which resolves domains using the names of running docker containers.
Generally you want to run SeaDNS as a docker container itself, and then set your /etc/resolv.conf or add an entry to /etc/resolvers/*.
-
Pull the image:
docker pull seadns -
Start the server:
docker run -d seadns serve -
Set your DNS:
docker run seadns nameserver -f osx > /etc/resolvers/sea -
echo "nameserver $(docker inspect -f "{{ .NetworkSettings.IPAddress }}.53" seadns)" > /etc/resolvers/sea
The seadns:masq image provides a proxy to seadns
-
Pull the image:
docker pull seadns -
Start the server:
docker run -d seadns serve --recurse -
Set your nameserver to the output of
docker run seadns nameserver -f generic -
Set your nameserver to the output of
docker inspect -f "{{ .NetworkSettings.IPAddress }}:53" seadns
Follow Step 1 above for your platform, then use the following for step 2 & 3:
docker run -d -p 53:53 seadns seadnsecho "nameserver $(docker-machine ip $DOCKER_MACHINE_NAME).$(docker port seadns 53 | grep -o ":[0-9]\+$" | cut -d: -f2)\n" > /etc/resolvers/sea
docker run -d -p 53:53 seadns:masq seadns- ``
SeaDNS exposes three services which work in tandem: a DNS server for responding to .sea queries and reverse proxy servers for HTTP and HTTPS which read the Host header and route the request to a docker container based on that.
