Registrator

Service registry bridge for Docker.

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.

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.

$ docker run -d \
    --name=registrator \
    --net=host \
    --volume=/var/run/docker.sock:/tmp/docker.sock \
    gliderlabs/registrator:latest \
      consul://localhost:8500
