Jeff Geerling on YouTube made a video about the installation of this chart:
helm repo add mojo2600 https://mojo2600.github.io/pihole-kubernetes/
helm repo updateThe following items can be set via --set flag during installation or configured by editing the values.yaml directly.
- Ingress: The ingress controller must be installed in the Kubernetes cluster.
- ClusterIP: Exposes the service on a cluster-internal IP. Choosing this value makes the service only reachable from within the cluster.
- LoadBalancer: Exposes the service externally using a cloud provider’s load balancer.
dnsmasq:
customDnsEntries:
- address=/nas/192.168.178.10
customCnameEntries:
- cname=foo.nas,nas
persistentVolumeClaim:
enabled: true
serviceWeb:
loadBalancerIP: 192.168.178.252
annotations:
metallb.universe.tf/allow-shared-ip: pihole-svc
type: LoadBalancer
serviceDns:
loadBalancerIP: 192.168.178.252
annotations:
metallb.universe.tf/allow-shared-ip: pihole-svc
type: LoadBalancerBy default, pihole-kubernetes will configure pod DNS automatically to use Google's 8.8.8.8 nameserver for upstream
DNS resolution. You can configure this, or opt-out of pod DNS configuration completely.
For example, to use Cloudflare's resolver:
podDnsConfig:
enabled: true
policy: "None"
nameservers:
- 127.0.0.1
- 1.1.1.1If you have other DNS policy at play (for example, when running a service mesh), you may not want to have
pihole-kubernetes control this behavior. In that case, you can disable DNS configuration on pihole pods:
podDnsConfig:
enabled: falseThis version splits the DHCP service into its own resource and puts the configuration to serviceDhcp.
If you have not changed any configuration for serviceDns, you don’t need to do anything.
If you have changed your serviceDns configuration, copy your serviceDns section into a new serviceDhcp section.
To enhance compatibility for Traefik, we split the TCP and UDP service into Web and DNS. This means, if you have a dedicated configuration for the service, you have to
update your values.yaml and add a new configuration for this new service.
Before (In my case, with metallb):
serviceTCP:
loadBalancerIP: 192.168.178.252
annotations:
metallb.universe.tf/allow-shared-ip: pihole-svc
serviceUDP:
loadBalancerIP: 192.168.178.252
annotations:
metallb.universe.tf/allow-shared-ip: pihole-svc
After:
serviceWeb:
loadBalancerIP: 192.168.178.252
annotations:
metallb.universe.tf/allow-shared-ip: pihole-svc
serviceDns:
loadBalancerIP: 192.168.178.252
annotations:
metallb.universe.tf/allow-shared-ip: pihole-svc
Version 1.8.22 has switched from the deprecated ingress api extensions/v1beta1 to the go forward version networking.k8s.io/v1. This means that your cluster must be running 1.19.x as this api is not available on older versions. If necessary to run on an older Kubernetes Version, it can be done by modifying the ingress.yaml and changing the api definition back. The backend definition would also change from:
backend:
service:
name: \{\{ $serviceName \}\}
port:
name: http
to:
backend:
serviceName: \{\{ $serviceName \}\}
servicePort: http

pihole seems to work without issue in MetalLB 0.8.1+
MetalLB 0.7.3 has a bug, where the service is not announced anymore, when the pod changes (e.g. update of a deployment). My workaround is to restart the metallb-speaker-* pods.
