publisher

Publisher listens directly to a docker socket bind-mounted into the container and listens to the docker events API for running containers on the host. Deis applications are published to etcd for service discovery.

Running this Container

Set $ETCD_HOST to be the IP address/hostname of the etcd endpoint you wish to target, and $HOST to be the IP address of the host running this container:

$ docker run -d -v /var/run/docker.sock:/tmp/docker.sock -e ETCD_HOST=192.168.0.1 -e HOST=192.168.0.1 deis/publisher

Building from Source

To build the image, run make build.

The build/runtime environment is split into two parts:

The build environment

Based on deis/go, this image installs Go and compiles publisher into a binary.

The runtime environment

Leveraging the build environment, this image pulls in the standalone binary compiled in the build environment and injects it into a minimal standalone container, minimizing the disk space footprint that this image takes up. In fact, this image is < 5MB:
