Immich Deployment Notes

This guide summarizes key configuration details for running Immich with GitOps.

Prerequisites

• Kubernetes cluster with the Zalando Postgres Operator (acid.zalan.do/v1) installed
• immich namespace created
• External Secrets Operator available
• Helm CLI and kubectl configured

Configuration Overview

PostgreSQL Extensions

Ensure the Immich database includes the pgvector and vectorchord extensions:

# k8s/applications/media/immich/database.yaml
spec:
  preparedDatabases:
    immich:
      extensions:
        pgvector: public
        vectorchord: public

Templated DB_URL

The application expects a single DB_URL. Use ExternalSecrets to assemble the connection string:

# k8s/applications/media/immich/externalsecret.yaml
template:
  data:
    DB_URL: >-
      postgres://immich:{{ .password }}@immich-postgresql:5432/immich?sslmode=require&sslmode=no-verify

External Secrets Permissions

Reference the cluster CA and grant read access to the Zalando secret:

1. zalando-k8s-store.yaml references kube-root-ca.crt.
2. serviceaccount.yaml grants get, list, and watch on secrets as well as selfsubjectrulesreviews.

Kustomization Layout

Use a root kustomization.yaml to track all resources:

resources:
  - namespace.yaml
  - http-route.yaml
  - externalsecret.yaml
  - database.yaml
  - pvc.yaml
  - zalando-k8s-store.yaml
  - serviceaccount.yaml

OAuth Configuration via ExternalSecret

Immich expects the OAuth client details inside its config file. The immich-config-external-secret.yaml resource pulls these values from Bitwarden and renders the full configuration as a Secret:

# k8s/applications/media/immich/immich-server/immich-config-external-secret.yaml
spec:
  template:
    data:
        immich-config.yaml: |
          ...
          server:
            externalDomain: https://photo.pc-tips.se
          oauth:
            enabled: true
            issuerUrl: "https://sso.pc-tips.se/application/o/immich/"
            scope: "openid email profile"
            autoLaunch: true
            autoRegister: true
            buttonText: "Login with SSO"
            clientId: "{{ .clientId }}"
            clientSecret: "{{ .clientSecret }}"
          passwordLogin:
            enabled: false

This Secret is mounted by the StatefulSet at /config/immich-config.yaml, allowing the application to start without additional environment variables. The machine learning deployment mounts the same Secret so both components read identical settings.

Resource Requests

Both pods need enough memory to process photos without crashing. A good starting point is:

Component	CPU Request	Memory Request	CPU Limit	Memory Limit
immich-server	500m	512Mi	2000m	2Gi
immich-machine-learning	200m	1Gi	1000m	4Gi

Library Storage

Immich stores uploaded files on a Persistent Volume Claim named library. The claim requests 40Gi from Longhorn:

# k8s/applications/media/immich/immich-server/statefulset.yaml
spec:
  volumeClaimTemplates:
  - metadata:
      name: library
    spec:
      storageClassName: longhorn
      accessModes: [ "ReadWriteOnce" ]
      resources:
        requests:
          storage: 40Gi
