@srnd/vagabond v1.1.1

Vagabond

A lightweight scaffolding system for building your own Nomad template system.

Vagabond will take a .yml taskspec file as input, and pass the config to the render export of template.js, which is expected to generate Nomad-capable (JSON-style) object in some way.

Optionally, your module may export a mergePrevious(job, previous) method which receives the currently running job spec (if any) and returns the final job object. This is useful for, e.g., not updating the count on a task group, or not updating the tag of a running docker container, allowing you to maintain deployment state separate from config.

For an example check out the jobs folder in srnd/containercfg.

Commands

• render - Renders the JSON
• plan - Shows the execution plan, and provides the Job Modify Index value
• run - Runs the job on the live cluster

Syntax and ENV variables are similar to the nomad utility.
