Configuration container for Docker & Rancher
Full Description

We ahead's configuration container

This container is used for providing configuration files generated with
confd for other containers via

This image uses Rancher's Metadata Service
as a backend for confd. When deployed on Rancher it will
properly use Ranchers Metadata service, if it is unavailable due to deployment
elsewhere (like during development) it will start its own metadata service
based on a release of Rancher Metadata.

Both confd and Rancher metadata run as non-root user inside the container.

How to use

FROM weahead/conf:3.0.3

VOLUME /usr/local/etc/<name>

Make sure your template resources are output to the volume location specified
in your Dockerfile.

Build it.

How to use the built in Rancher metadata

  • Create a YAML file and make it available at /answers.yml inside the
  • Edit it to suite your needs.

See example: answers.example.yml

A note on Docker Hub

The above Dockerfile can be made even simpler by using Dockers ONBUILD and
ARG instructions together, leaving just the FROM instruction. Unfortunately
the Docker Hub is still running 1.8, which does not support the ARG
instruction. There is an issue tracking the support for 1.9 features on Docker
Hub, #460
