Guestbook

Guestbook is a simple, multi-tier PHP-based web application that uses redis chart.

TL;DR;

$ helm install stable/guestbook

Introduction

This chart bootstraps a guestbook deployment on a Kubernetes cluster using the Helm package manager.

It also packages the Bitnami Redis chart which is required for bootstrapping a Redis deployment for the caching requirements of the guestbook application.

Prerequisites

• Kubernetes 1.4+ with Beta APIs enabled
• PV provisioner support in the underlying infrastructure

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release stable/guestbook

The command deploys the guestbook on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Configuration

The following tables lists the configurable parameters of the WordPress chart and their default values.

Parameter	Description	Default
image	apapche-php image	google-samples/gb-frontend:{VERSION}
imagePullPolicy	Image pull policy	IfNotPresent
nodeSelector	Node labels for pod assignment	{}

The above parameters map to the env variables defined in bitnami/wordpress. For more information please refer to the bitnami/wordpress image documentation.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install --name my-release \
  --set redis.usePassword=false \
    stable/guestbook

$ helm install --name my-release -f values.yaml stable/guestbook

Tip: You can use the default values.yaml
