I’m a DevOps architect, musician, animal lover and all-round geek. If it’s got shiny lights on it, makes loud noises or purrs/wags its tail when you stroke it, I’m all for it. When I’m not writing code or fiddling with computers for a living, I produce my own music and provide the low-end rumble for my band in West Sussex.

Tiller 0.7.6 and environment JSON v2

I recently released Tiller 0.7.6 with a new feature for the environment_json plugin. This can be used to provide dynamic configuration for Docker containers, using JSON in an environment variable.

Some of it is internal stuff that you’ll probably only notice if you’re building your own plugins for Tiller, but there is a fairly big new feature for end users: Single-file configuration.

Centralized Docker container configuration with Tiller

If you’ve been using Docker for a while, you probably know that you can use Tiller to generate configuration files inside your containers. This means you can provide a single container for running in a variety of different environments (think of a web application that needs different database URIs and credentials depending on where it is run).

Tiller 0.5.0 released

Just a quick “heads up” for users of Tiller - version 0.5.0 has just been released and has a few new features, and some other changes. Firstly, I have added support for per-environment common settings. Normally, you’d do things like enable the API, set the exec parameter and so on in common.yaml, but as per issue #10, you can now specify / over-ride these settings in your environment configuration blocks. Simply drop them under a common: section, e.g.
