kube-lego

kube-lego automatically requests certificates for Kubernetes Ingress resources from Let's Encrypt.

TL;DR;

$ helm install stable/kube-lego

Introduction

This chart bootstraps a kube-lego deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.4+ with Beta APIs enabled

Installing the Chart

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

$ helm install --name my-release stable/kube-lego

The command deploys kube-lego 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 table lists the configurable parameters of the chart and their default values.

Parameter	Description	Default
config.LEGO_EMAIL	email address to use for registration with Let's Encrypt	none
config.LEGO_URL	Let's Encrypt API endpoint	https://acme-staging.api.letsencrypt.org/directory (staging)
config.LEGO_PORT	kube-lego port	8080
image.repository	kube-lego container image repository	jetstack/kube-lego
image.tag	kube-lego container image tag	0.1.3
image.pullPolicy	kube-lego container image pull policy	IfNotPresent
nodeSelector	node labels for pod assignment	{}
podAnnotations	annotations to be added to pods	{}
replicaCount	desired number of pods	1
resources	kube-lego resource requests and limits (YAML)	{}

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

$ helm install --name my-release \
  --set config.LEGO_EMAIL=you@domain.tld \
    stable/kube-lego

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

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

Tip: You can use the default values.yaml
