Goverseer

Goverseer is a tool for monitoring some kind of upstream, and taking actions when a change is detected. In some ways it is similar to consul-template, except Goverseer does not handle templating. Instead it is focused on watching for changes and taking some kind of action based on those changes.

Usage

Goverseer is configured using a yaml config file. The goverseer start command takes a path to the config file. If a config path is not provided, /etc/goverseer.yaml will be used.

# Example goverseer config
---
name: example

watcher:
  type: time
  config:
    poll_seconds: 1

executioner:
  type: log
  config:
    tag: example

The available values for watcher.type are:

• file: File Watcher
• gce_metadata: GCE Metadata Watcher
• time: Time Watcher

The available values for executioner.type are:

• log: Log Executioner
• shell: Shell Executioner

The configuration options for watcher.config and executioner.config are determined by the selected type. See the documentation for the specific watcher and executioner type for more details on available configuration options.

Building

To build Goverseer, simply run make build. Once complete, you should see a binary in the root of your checkout.
