Home Assistant Helm Chart

A Helm chart for Home Assistant with PostgreSQL recorder support, managed secrets, and Kubernetes-native logging.

Features

• PostgreSQL Recorder: Optional PostgreSQL backend for HA recorder with automated database and user creation via db-init job.
• Managed Secrets: HA secrets.yaml generated from Kubernetes Secrets (works with sealed-secrets).
• Kubernetes-native Logging: Log file disabled, all logs go to stdout (kubectl logs).
• Backups: Integrated CronJob for automated PostgreSQL backups with configurable retention and node pinning.
• Ingress: Dictionary-based multi-ingress support (e.g. external HTTPS + internal LAN).
• Host Network: Enabled by default for mDNS/HomeKit discovery.
• Persistence: Config and media volumes with hostPath or PVC support.

Installation

1. Create Secrets

PostgreSQL secret (if using postgres recorder):

apiVersion: v1
kind: Secret
metadata:
  name: ha-secret
stringData:
  HA_POSTGRESQL_PASSWORD: "<password>"
  POSTGRES_ADMIN_PASSWORD: "<admin-password>"

HA secrets (optional, for managing HA secrets.yaml):

apiVersion: v1
kind: Secret
metadata:
  name: ha-ha-secrets
stringData:
  api_key: "some-api-key"
  webhook_token: "some-token"

2. Configure Values

Review the values.yaml and create your override file.

3. Install

helm install my-ha ./home-assistant -f my-values.yaml

Architecture

Init Containers

1. init-config (always): Cleans up old log files from PVC.
2. init-secrets (when haSecrets.enabled): Generates /config/secrets.yaml from K8s Secret key-value pairs.
3. init-recorder (when postgres.enabled): Generates /config/recorder.yaml with PostgreSQL connection string and appends recorder: !include recorder.yaml to configuration.yaml.

Logging

The container patches the HA s6-overlay run script to pass --log-file /dev/null, disabling file-based logging. All logs go to stdout and are accessible via kubectl logs.
