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.
