One chart to rule them all

Fork of https://github.com/gimlet-io/onechart

Highly opinionated Helm Chart for our applications needs.

Because no-one, espacially us, can remember the Kubernetes yaml syntax.

Introduction

This Helm chart provides a DRY way to deploy applications in a Kubernetes cluster.

Important

This helm chart is designed for @IMIO specific needs and is not intended to resolve all use cases. But we are open to contributions and suggestions to improve this helm chart. This Helm chart runs OneChart forked version 0.73.0 and customized for our needs.

Getting started

OneChart is a generic Helm Chart for web applications. The idea is that most Kubernetes manifest look alike, only very few parts actually change.

Pull Helm release

helm repo add imio https://imio.github.io/helm-charts
helm repo update

Configure the chart

The following items can be set via --set flag during installation or configured by editing the values.yaml directly (need to download the chart first).

See the values.yaml file for more information.

Set your image name and version, the boilerplate is generated.

The example below deploys your application image, sets environment variables and configures the Kubernetes Ingress domain name:

helm repo add onechart https://chart.onechart.dev
helm template my-release onechart/onechart -f values.yaml

# values.yaml
image:
  repository: my-app
  tag: fd803fc
vars:
  VAR_1: "value 1"
  VAR_2: "value 2"
ingress:
  annotations:
    kubernetes.io/ingress.class: nginx
  host: my-app.mycompany.com

Install the chart

helm install [RELEASE_NAME] imio/onechart

or by cloning this repository:

git clone https://github.com/imio/helm-onechart.git
cd helm-onechart
helm repo update
helm dep up
helm upgrade onechart . -f values.yaml --namespace onechart --create-namespace --install
