Root cause: Dozzle was being rate-limited by the Kubernetes API when
fetching logs from many containers. The aggressive 1-second health check
timeouts caused the container to fail probes and restart repeatedly.
Changes:
- Increased all probe timeouts from 1s to 5s to handle API rate limiting
- Increased liveness probe period from 10s to 30s to reduce check frequency
- Increased readiness probe period from 5s to 10s
- Increased startup probe failure threshold from 15 to 20 (60s total startup time)
- Increased CPU limit from 500m to 1000m and request from 100m to 250m
- Increased memory limit from 512Mi to 1Gi and request from 128Mi to 256Mi
- Pinned image version to v10.6.10 instead of :latest
This prevents unnecessary restarts when Dozzle is waiting on rate-limited
Kubernetes API calls, fixing both the initial 503 errors and the connection
drops after prolonged use.

Fixes DEV-350. During pod startup, Dozzle takes ~11 seconds to start
accepting connections, but oauth2-proxy can receive and proxy requests
immediately. This causes "connection refused" errors when users access
the UI right after a pod restart.
Solution:
- Add startupProbe with 30s timeout (15 failures × 2s) to give Dozzle
time to start without failing readiness
- Add readinessProbe to prevent traffic routing until Dozzle is ready
- Add livenessProbe to restart container if Dozzle becomes unhealthy
All probes use the /healthcheck endpoint on port 8080.

The oauth2-proxy container was failing with "unknown flag: --proxy-buffer-size".
This flag is not valid for oauth2-proxy and has been removed.
Fixes DEV-349
Co-Authored-By: Paperclip <noreply@paperclip.ing>
Added oauth2-proxy flags to properly handle Server-Sent Events (SSE):
- --flush-interval=1s: Flush buffered data regularly for SSE
- --upstream-timeout=30s: Allow longer streaming connections
- --proxy-buffer-size=8k: Reduce buffering latency
Simplified ingress configuration to standard Traefik setup.
OAuth2-proxy was buffering responses by default, which broke the
WebSocket/SSE endpoints used for real-time log streaming. The
flush-interval flag ensures data is streamed properly.

oauth2-proxy was resolving localhost to IPv6 [::1]:8080 instead of
IPv4 127.0.0.1:8080, causing connection refused errors on the streaming
endpoints (/api/events/stream and /api/hosts/.../logs/stream).
Changed upstream URL from http://localhost:8080 to http://127.0.0.1:8080
to force IPv4 resolution.

Added WebSocket support configuration to both oauth2-proxy and Traefik ingress:
- Enable explicit WebSocket proxying in oauth2-proxy (--proxy-websockets=true)
- Pass Host header through oauth2-proxy (--pass-host-header=true)
- Add WebSocket upgrade headers to Traefik ingress annotations
This fixes the "UI cannot connect to API" error by ensuring real-time
log streaming WebSocket connections work through the authentication proxy.
Co-Authored-By: Paperclip <noreply@paperclip.ing>
Add Traefik WebSocket annotations to ingress to enable real-time log
streaming. Without these, the UI cannot establish WebSocket connections
to the API backend.

Dozzle running in k8s mode requires permission to list nodes at cluster
scope. Without this permission, the pod fails with error:
"nodes is forbidden: User \"system:serviceaccount:dozzle:dozzle\" cannot
list resource \"nodes\" in API group \"\" at the cluster scope"
This change adds the nodes resource with get, list, and watch verbs to
the ClusterRole, allowing Dozzle to discover all nodes in the cluster
when running in k8s/swarm mode.

Switch from direct OIDC (not supported by Dozzle) to forward-proxy authentication using oauth2-proxy as a sidecar container.
Changes:
- Add oauth2-proxy sidecar container for OIDC authentication
- Configure Dozzle to use forward-proxy auth with user headers
- Update service and ingress to route to oauth2-proxy (port 4180)
- Add cookie-secret to sealed secret for oauth2-proxy session management
- Update documentation to reflect oauth2-proxy architecture
The oauth2-proxy authenticates users via Pocket ID and forwards requests to Dozzle with X-Forwarded-User, X-Forwarded-Email, and X-Forwarded-Preferred-Username headers.

dind sidecar had networking issue: host-networked job containers can't reach
the dind daemon inside the pod. Back to host socket with docker binary
bind-mounted into job containers via container.options.
The forgejo-runner image doesn't include Docker CLI by default, causing
the startup script to hang waiting for Docker to be ready. Install
docker-cli via apk during startup to enable Docker socket access.
This completes the DinD setup for the runner.

Replaces the Deployment-based runner with a StatefulSet using a proper
Docker-in-Docker sidecar for improved isolation and state management.
Key changes:
- StatefulSet deployment for stable pod identity and persistent storage
- Docker-in-Docker init container (privileged) providing isolated Docker daemon
- Two persistent volumes: runner-data (1Gi) for config, docker-data (20Gi) for image cache
- Uses hcloud-volumes storage class for durability
- Each replica gets its own Docker daemon and image cache
This addresses the workflow failure where job containers (node:24-bookworm)
couldn't access Docker because the CLI was missing. The DinD sidecar provides
a complete Docker environment for all job containers.

Docker containers launched by the runner on the host cannot resolve
forgejo.forgejo.svc.cluster.local (k8s cluster DNS is not available
from host Docker containers). Switching to https://forgejo.basicstack.de

externally reachable URL, fixing git fetch in actions/checkout.
Also adds detection to force re-registration if a pod starts with the
old internal-URL .runner file still present.

Change runner container network from bridge to host to allow workflow

Move Helm chart configuration from inline values in app-harbor.yaml to
separate files in apps/harbor/ subdirectory, following the same pattern
as forgejo and other apps.
Changes:
- Create apps/harbor/Chart.yaml defining dependency on Harbor Helm chart
- Create apps/harbor/values.yaml with all Helm values configuration
- Update app-harbor.yaml to use git path source instead of direct Helm chart
- Add apps/harbor/README.md documenting OIDC setup procedure
OIDC authentication must be configured via Harbor UI after deployment,
as the Helm chart does not support OIDC configuration at deployment time.
The README provides step-by-step instructions for Pocket ID integration.

- Resource limits for all components
- Created sealed secret with Harbor admin password, database password, and OIDC client secret
- Configured DNS A record for harbor.basicstack.de -> 178.105.17.239

Set HEADLAMP_CONFIG_BASE_URL to https://headlamp.basicstack.de to ensure

Headlamp's BASE_URL config expects a path prefix (e.g., "/headlamp") or empty
string, not a full URL. Since Headlamp is deployed at the domain root, BASE_URL
should be empty.
The OIDC redirect URIs in Pocket ID are correctly configured and the user has
been added to the headlamp group, which should resolve the authentication issue.

The missing BASE_URL caused the OIDC redirect flow to fail, resulting in the
