Kuberun

How many time you had to run long running, resource exhausting command on Kubernetes pod and afterwards it was killed by autoscaling/memory limit or deployment made by someone?

This CLI tool aims to create completely separate pod for those commands without having to manually code its configuration.

Uses kubectl inside.

Status

This tool is in early alpha stage.

Features

Run pod based on deployment spec
Possibility to auto-delete pod after command is done
Search for applicable pods before starting new one

Incoming:

specify different resources for containers
specify your own command to keep pod running (instead of /bin/sh and sleep)
specify actual command (currently it's /bin/sh)

Installation

Dependencies:

Ruby >= 2.4
kubectl in $PATH

Add this line to your application's Gemfile (preferably in development group):

gem 'kuberun'

And then execute:

$ bundle

Or install it yourself as:

$ gem install kuberun

Usage

kuberun help

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
