Service registry bridge for Docker.

Circle CI Docker pulls IRC Channel

Registrator automatically registers and deregisters services for any Docker container by inspecting containers as they come online. Registrator supports pluggable service registries, which currently includes Consul, etcd and SkyDNS 2.

Full documentation available at

Getting Registrator

Get the latest release, master, or any version of Registrator via Docker Hub:

$ docker pull gliderlabs/registrator:latest

Latest tag always points to the latest release. There is also a :master tag and version tags to pin to specific releases.

Using Registrator

The quickest way to see Registrator in action is our Quickstart tutorial. Otherwise, jump to the Run Reference in the User Guide. Typically, running Registrator looks like this:

$ docker run -d \
    --name=registrator \
    --net=host \
    --volume=/var/run/docker.sock:/tmp/docker.sock \
    gliderlabs/registrator:latest \
