Diamond Docker

Dockerfiles for collecting host metrics using Diamond.

There are multiple Dockerfiles included in this repo, each used for a separate step in the build:

• Dockerfile.deps: Used to build an image based on Debian Jessie including dependencies required in both the build and runtime.
• Dockerfile: Buildtime image, used to build a .deb package of diamond. Includes build-specific dependencies.
• Dockerfile.run: The runtime image for Diamond. Includes only those dependencies required at runtime.

This design has two major goals:

• Reduce the size of the final runtime image, by ensuring that buildtime dependencies such as make and git are only included in the build-time image.
• Remove any dependencies from the developer's machine. To build the image, the developer only needs to have a working Docker setup.

To build:

$ docker build -t builder . && docker run builder | docker build -t diamond -

To run:

$ docker run diamond
