Command line helper for helm.

This utility adds to the functionality of Helm (opens new window) in multiple ways:

Creates a declarative syntax to manage multiple releases in one place
Allows installation of charts from a git commit/branch/release

# Requirements

helm (>= 3.0.0), installed and initialized

Helm2 is untested as of v4.3.0. The maintainers of helm have deprecated helm2 (opens new window).

# Quickstart

In course.yml, write:

namespace: default
charts:
  grafana:
    namespace: grafana
    values:
      image:
        tag: "6.2.5"
  polaris-dashboard:
    namespace: polaris-dashboard
    repository:
      git: https://github.com/FairwindsOps/charts
      path: stable
    chart: polaris

Then run:

reckoner plot course.yml --run-all

Grafana and Polaris should now be installed on your cluster!

# Importing Existing Releases

Importing existing releases is experimental and the result should be reviewed.

If you're already using Helm but want to start using reckoner, you can use reckoner import to facilitate your migration.

We recommend carefully examining the output of a reckoner diff before relying on any imported course.yml definitions.
