HELM Chart for Puppet Server

Introduction

This chart bootstraps Puppet Server and its components on a Kubernetes cluster using the Helm package manager.

Prerequisites

Code Repos

Load-Balancing Puppet Server

In case a Load Balancer (LB) must sit in front of Puppet Server - please keep in mind that having a Network LB (operating at OSI Layer 4) is preferable.

NGINX Ingress Controller Configuration

The Ingress resource is disabled by default, but if it is enabled then ssl-passthrough must be used so that puppet agents will get the expected server certificate when connecting to the service. This feature must be enabled on the Ingress resource itself, but also must be enabled via command line argument to the NGINX Ingress Controller. More information on that can be found here.

NOTE: Ingress URLs must be passed in the Values.puppetserver.masters.fqdns.alternateServerNames. Also - in the Values.puppetserver.compilers.fqdns.alternateServerNames (if Puppet Compilers and their Ingress resources are deployed).

Migrating from Bare-Metal Puppet Infrastructure

Auto-Signing Certificate Requests

In general, the easiest way to switch the Puppet Agents from using one Puppet master to another is by enabling the auto-signing of CSRs. By default, that has been pre-enabled in the Puppet Server Docker container. It can be disabled in the Values file by passing an extra environment variable: AUTOSIGN=false (in .Values.puppetserver.masters.extraEnv).

You will also need to remove the existing certificates in /etc/puppetlabs/puppet/ssl on each Puppet agent.

Using Pre-Generated Puppet Master Certificates

If you prefer not to auto-sign or manually sign the Puppet Agents’ CSRs - you can use the same Puppet master and PuppetDB certificates which you used in your bare-metal setup. Please archive into two separate files and place your certificates in the init/puppet-certs/puppetserver and init/puppet-certs/puppetdb directories and enable their usage in the Values file (.Values.puppetserver.preGeneratedCertsJob.enabled).

NOTE: For more information please check - README.md. For more general knowledge on the matter you can also read the article - https://puppet.com/docs/puppet/5.5/ssl_regenerate_certificates.html.

Using Single CA

If you prefer, you can use a single externally issued CA - https://puppet.com/docs/puppet/7/config_ssl_external_ca.html.
Enable it with .Values.singleCA.enable, add the crl.pem url with .Values.singleCA.crl.url.

Generate puppet & puppetdb secret (must be name puppet.pem & puppetdb.pem):

kubectl create secret generic puppet-certificate --from-file=puppet.pem --from-file=puppet.key --from-file=ca.pem
kubectl create secret generic puppetdb-certificate --from-file=puppetdb.pem --from-file=puppetdb.key --from-file=ca.pem

finally set .Values.singleCA.certificates.existingSecret.puppetserver and .Values.singleCA.certificates.existingSecret.puppetdb.

Additionnaly, if you use a public certificate authority, you can’t use private SAN name, so you have to override puppetdb name with .Values.singleCA.puppetdb.overrideHostname (with the full name ie: puppetdb.my.domain)

If you prefer, you can use crl update as cronjob instead of sidecar, it reduce resources utilization because only 1 pod is running.
:warning: it may not work on multi zone cluster. that why it’s not enable by default

Horizontal Scaling

To achieve better availability and higher throughput of Puppet Infrastructure, you’ll need to scale out Puppet Masters and/or Puppet Compilers.

Multiple Puppet Masters

To achieve better availability of Puppet Infrastructure, you can scale out Puppet Server Masters using .Values.puppetserver.masters.multiMasters. These Servers are known as masters, and are responsible for the creation and signing of your Puppet Agents’ certificates. They are also responsible for receiving catalog requests from agents and synchronize the results with each other.

Multiple Puppet Compilers

To achieve better throughput of Puppet Infrastructure, you can enable and scale out Puppet Server Compilers using .Values.puppetserver.compilers. These Servers are known as compile masters, and are simply additional load-balanced Puppet Servers that receive catalog requests from agents and synchronize the results with each other.

Multiple PostgreSQL Read Replicas

For now it’s not available anymore, since bitnami cleanned their old release. for multiple Postgresql we have to use postgresql-ha.
Read replica return an error on puppetdb:
ERROR [p.p.c.services] Will retry database connection after temporary failure: java.sql.SQLTransientConnectionException: PDBMigrationsPool: default - Connection is not available, request timed out after 3002ms.

Deploy R10K as deployment

:warning: may not work in multi zone environment. that why it’s not enable by default

You can configure r10k to run as deployment instead of sidecar to avoid r10k container multiplication (and avoid r10k run conflict) to share r10k data between all componant (master or compiler), change the following values:

# values.yaml

# change this only if you use compilers
puppetserver:
    compilers:
        kind: Deployment

r10k:
  asSidecar: false

Deploy Puppetserver deployment (master & compilers) as non root

:warning: for now only puppetserver can run as non root, it’s not available for the puppetdb It will run a pre-install job to configure all repository & permissions for masters & compilers

Benefits:

You can enable it using:

global.runAsNonRoot: true

Chart Components

Installing the Chart

Add Puppet Server Helm Repository

Before installing Puppet Server Helm chart, you need to add the Puppet Server Helm repository to your Helm client as below.

helm repo add puppet https://puppetlabs.github.io/puppetserver-helm-chart

Install the Chart

To install the chart with the release name puppetserver.

helm install --namespace puppetserver --name puppetserver puppet/puppetserver --set puppetserver.puppeturl='https://github.com/$SOMEUSER/control-repo.git'

Note - If you do not specify a name, helm will select a name for you.

Installed Components

You can use kubectl get to view all of the installed components.

$ kubectl get --namespace puppetserver all

Upgrading

from 7.x to 8.0

customPersistentVolumeClaim was removed instead check puppetdb.persistence.existingClaim or puppetserver.persistence.*.existingClaim for similar functionnality.

Added support for setting the size and Storage Class of individual Persistent Volume Claims fullfilling most uses of customPersistentVolumeClaim check puppetdb.persistence.size puppetdb.persistence.storageClass, puppetserver.persistence.*.storageClass and puppetserver.persistence.*.size for more information.

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

helm install --namespace puppetserver --name puppetserver puppet/puppetserver --set puppetserver.puppeturl='https://github.com/$SOMEUSER/puppet.git',hiera.hieradataurl='https://github.com/$SOMEUSER/hieradata.git'

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

helm install --namespace puppetserver --name puppetserver puppet/puppetserver -f values.yaml

Tip: You can use the default values.yaml

Testing Helm Chart (in progress)

https://github.com/quintush/helm-unittest/

It would be great to test all ressources to avoid regression in the future

run test:

helm unittest . -3
