localhost resolves to IPv6 ::1 but containers bind to 0.0.0.0 (IPv4
only), causing wget to fail with "Connection refused". The nginx
proxy had 18,462 consecutive health check failures because of this.
Also cleared corrupted pull-through cache for mghee/novelapp — the
registry had layer link files pointing to non-existent blob data,
causing containerd to get 200 responses with 0 bytes (unexpected EOF).
- Add auth.htpasswd section to config-private.yml
- Mount htpasswd file in registry-private container, fix healthcheck for 401
- Rename registry UI from registry.viktorbarzin.me → docker.viktorbarzin.me
- Add Docker CLI ingress at registry.viktorbarzin.me (HTTPS backend, no rate-limit, unlimited body)
- Add docker to cloudflare_proxied_names (registry stays non-proxied)
- Add Kyverno ClusterPolicy to sync registry-credentials secret to all namespaces
- Update infra provisioning to install apache2-utils and generate htpasswd from Vault
Replace individual `docker run` commands with Docker Compose stack managed
by systemd. Nginx now fronts all 5 registry ports (5000/5010/5020/5030/5040)
with proxy_cache_lock to serialize concurrent blob pulls and prevent
corrupt partial responses. Adds QEMU guest agent for remote management.
