Switchboard Helm Chart

Type: application Artifact Hub License

This repository contains the Helm chart as well as detailed instructions for deploying the Switchboard Kubernetes operator. Please read through the main repository's README to understand how Switchboard works.

Installation

Prerequisities

Since Switchboard processes Traefik CRDs, you must make sure that your Kubernetes cluster has all Traefik v2 CRDs installed.

Depending on the integrations that you want to enable, you further need to have the following components installed:

  • cert-manager integration: Requires cert-manager and its CRDs to be installed. Can optionally be done by setting cert-manager.install = true in this chart.
  • external-dns integration: Requires external-dns along with its DNSEndpoint CRD installed. Can optionally be done by setting external-dns.install = true in this chart.

Install

Switchboard can be installed with Helm version >= 3.7.0. For Helm version < 3.8.0, you need to set HELM_EXPERIMENTAL_OCI=1. Then you can install the chart directly with the following command:

helm install switchboard oci://ghcr.io/borchero/charts/switchboard

By default, this installs Switchboard with no integrations enabled, i.e. it will not create any resources. Integrations can be enabled by setting integrations.<name>.enabled to true. Consult the configuration options to check which integrations you want to enable.

Note: You can check your Helm version via helm version.

Values

The following lists all values that may be set when installing this chart (see values.yaml for a more structured overview):

Key Type Default Description
cert-manager.install bool false Whether the cert-manager chart should be installed. See: https://artifacthub.io/packages/helm/cert-manager/cert-manager
certificateIssuer.create bool false Whether an ACME certificate issuer should be created for use with cert-manager.
certificateIssuer.email string nil
certificateIssuer.solvers list [] The solvers to use for verifying that the domain is owned in the ACME challenge. See: https://cert-manager.io/docs/configuration/acme/
external-dns.install bool false Whether the external-dns chart should be installed. If installed manually, make sure to add the crd item to the sources. See: https://artifacthub.io/packages/helm/external-dns/external-dns
image.name string "ghcr.io/borchero/switchboard" The switchboard image to use.
image.tag string "0.3.0" The switchboard image tag to use.
integrations.certManager.enabled bool false Whether the cert-manager integration should be enabled. If enabled, Certificate resources are created by Switchboard. Setting this to true requires specifying an issuer via integrations.certManager.issuer or letting the chart create its own issuer by setting certificateIssuer.create = true and specifying additional properties for the certificate issuer.
integrations.certManager.issuer.kind string nil The kind of certificate issuer to use for obtaining TLS certificates.
integrations.certManager.issuer.name string nil The name of the certificate issuer to use for obtaining TLS certificates.
integrations.externalDNS.enabled bool false Whether the external-dns integration should be enabled. If enabled DNSEndpoint resources are created by Switchboard. Setting this to true requires specifying the target via integrations.externalDNS.target.
integrations.externalDNS.targetIPs list [] The static IP addresses that created DNS records should point to. Must not be provided if the target service is set.
integrations.externalDNS.targetService.name string nil The name of the (Traefik) service whose IP address should be used for DNS records.
integrations.externalDNS.targetService.namespace string nil The namespace of the (Traefik) service whose IP address should be used for DNS records.
metrics.enabled bool true Whether the metrics endpoint should be enabled.
metrics.port int 9090 The port on which Prometheus metrics can be scraped on path /metrics.
podAnnotations object {} Annotations to set on the switchboard pod.
podMonitor.create bool false Whether a PodMonitor should be created which can be used to scrape the metrics endpoint. Ignored if metrics.enabled is set to false
podMonitor.namespace string nil The namespace where the monitor should be created in. Defaults to the release namespace.
replicas int 1 The number of manager replicas to use.
resources object {} The resources to use for the operator.
selector.ingressClass string nil When set, Switchboard only processes ingress routes with the kubernetes.io/ingress.class annotation set to this value.
