flickr-immich-k8s-sync-operator 0.0.2

Operator for syncing photos from Flickr to Immich on Kubernetes

flickr-immich-k8s-sync-operator

Kubernetes operator that watches per-user Flickr download Jobs in a namespace, restarts failed Jobs after a configurable delay, and retrieves pod logs and exit codes for failed Jobs before restarting them. Designed to run alongside Immich (self-hosted photo management).

Operator in Action

The operator monitoring Flickr download Jobs in k9s, detecting failures, and scheduling restarts.

Status

Beta (v0.0.1) — the core job-restart loop is implemented and functional. The project scaffolding (packaging, Docker image, CI) is in place.

Architecture

• Runs as a single-replica Deployment in a dedicated namespace (default: flickr-downloader)
• Uses the Kubernetes Python client with in-cluster config
• Periodically checks configured Job names for failure conditions
• On failure (after a configurable delay), deletes the Job with Foreground propagation policy and recreates it from a cached manifest
• Logs pod exit codes and tail logs before every restart

How it works

1. An Ansible playbook (kubectlstuff_flickr_downloader.yml) creates per-user Flickr download Jobs in the flickr-downloader namespace
2. Each Job runs flickr_download with BACKOFF_EXIT_ON_429=true, so it exits immediately on HTTP 429 rate-limit errors instead of sleeping
3. Jobs mount host directories for config, backup, and cache per user
4. This operator watches all configured Jobs for failure conditions
5. When a Job fails, the operator logs pod exit codes and tail logs, waits RESTART_DELAY seconds (default 1 hour), then deletes and recreates the Job from a cached manifest
6. The operator uses namespace-scoped RBAC with minimal permissions (Jobs, Pods, Pod logs)

Prerequisites

• A running Kubernetes cluster
• Per-user Flickr download Jobs already deployed (e.g. via the Ansible playbook above) — the operator manages their lifecycle (restart on failure), not initial creation
• An Immich instance (for planned sync functionality)

Configuration

Variable	Description	Default
LOGURU_LEVEL	Log verbosity (DEBUG, INFO, WARNING, …)	DEBUG
NAMESPACE	Namespace to watch	flickr-downloader
JOB_NAMES	Comma-separated Job names to monitor (required)	—

SKIP_DELAY_ON_OOM	Skip restart delay when failure reason is OOMKilled	false

Kubernetes Deployment

RBAC

The operator requires a ServiceAccount with a Role scoped to the target namespace:

apiVersion: v1
kind: ServiceAccount
metadata:
  name: flickr-operator
  namespace: flickr-downloader
---
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  name: flickr-operator
  namespace: flickr-downloader
rules:
  - apiGroups: ["batch"]
    resources: ["jobs"]
    verbs: ["get", "list", "create", "delete"]
  - apiGroups: [""]
    resources: ["pods"]
    verbs: ["get", "list", "delete"]
  - apiGroups: [""]
    resources: ["pods/log"]
    verbs: ["get"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
