cert-manager Helm Chart

This Helm chart deploys cert-manager, a Kubernetes add-on that automates the management and issuance of TLS certificates from various certificate authorities, including Let's Encrypt.

Prerequisites

  • Kubernetes 1.16+
  • Helm v3.x

Installation

  1. Add the cert-manager Helm repository:

helm repo add jetstack https://charts.jetstack.io helm repo update

  1. Install the cert-manager Helm chart:

helm install cert-manager jetstack/cert-manager --namespace cert-manager --create-namespace --version v1.7.1

To customize the installation, you can create a custom values file and pass it during the installation using the --values flag. For available options, please see the cert-manager documentation.

Configuration

After installing cert-manager, you need to configure an issuer or cluster issuer for certificate management. Please refer to the official documentation for more information on configuring issuers.

Usage

To request a certificate, create a Certificate resource in your Kubernetes cluster that refers to the issuer you have configured. For example:

apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
name: my-certificate
namespace: default
spec:
secretName: my-certificate-tls
dnsNames:
 - example.com
issuerRef:
 name: my-issuer
 kind: Issuer

For more information on using cert-manager, please refer to the official documentation.
