Photon taster: Flirting with VMware's CoreOS gambit

There's growing interest in VMware’s Photon. Essentially, Photon lets highly optimised Docker containers into VMware Land.

You can specify whatever name you like. The convention is author/project:tag. if you want to publish your dockerfiles, the author field should be unique AIUI.

Eg, on my personal machine, I have the following Docker images:

diodesign/debian-x11:latest

rust:1.20.0

diodesign/debian-verilog:latest

diodesign/debian-gcc:testing

debian:testing

which are respectively:

My custom Debian-based X11 desktop

Standard Rust 1.20 build environment

My custom Debian-based Verilog dev environment

My custom Debian-based C/C++ dev environment

Standard Debian Testing install

Build an image from a Dockerfile

root@photon-machine [ /opt/mineserver ]#

So I try this:

root@photon-machine [ /opt/mineserver ]# docker build .
