## Summary - Remove aliases from all zk cards to prevent them from capturing wiki-links - Convert all wiki-links from `[[filename|Title]]` to `[[Title]]` format - Replace `doc-filenames` task with `doc-titles` for duplicate title detection - Update pre-commit hook to use `doc-titles` Wiki-links now resolve to reference docs by their frontmatter title, which is more readable and maintainable than filename-based links. ## Deployment and Testing - [x] Pre-commit hooks pass (including new `doc-titles` check) - [x] Manually verified zk cards have aliases removed - [ ] Deploy docs v1.0.7 and verify wiki-links resolve correctly - [ ] Test links to reference docs (e.g., [[Grafana Alloy]], [[ArgoCD]]) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/91

# Zot Registry Management Log
|
|
|
|
Zot is an OCI-native container registry running on Indri, providing:
|
|
1. Pull-through cache for Docker Hub, GHCR, Quay (avoids rate limits)
|
|
2. Private image storage for custom-built containers
|
|
|
|
## Service Details
|
|
|
|
- URL: https://registry.ops.eblu.me
|
|
- Local port: 5050
|
|
- Data directory: ~/zot
|
|
- Config: ~/.config/zot/config.json
|
|
- Managed via: mcquack LaunchAgent
|
|
|
|
## Namespace Convention
|
|
|
|
| Path | Source |
|
|
|------|--------|
|
|
| `registry.../docker.io/*` | Cached from Docker Hub |
|
|
| `registry.../ghcr.io/*` | Cached from GHCR |
|
|
| `registry.../quay.io/*` | Cached from Quay |
|
|
| `registry.../blumeops/*` | Private images (yours) |
|
|
|
|
## How It Works
|
|
|
|
### Pull-Through Cache (Automatic)
|
|
|
|
When [[minikube]] pulls an image like `docker.io/library/nginx:latest`:
|
|
1. Containerd checks zot first (via `host.minikube.internal:5050`)
|
|
2. If zot has it cached, returns immediately
|
|
3. If not, zot fetches from upstream, caches it, returns to k8s
|
|
|
|
Cached images appear under their original registry path (e.g., `docker.io/library/nginx`).
|
|
|
|
### Private Images (Manual Push)
|
|
|
|
Build and push from gilbert using podman:
|
|
```bash
|
|
# Build
|
|
podman build -t registry.ops.eblu.me/blumeops/myapp:v1 .
|
|
|
|
# Push to zot
|
|
podman push registry.ops.eblu.me/blumeops/myapp:v1
|
|
|
|
# Use in k8s manifest
|
|
image: registry.ops.eblu.me/blumeops/myapp:v1
|
|
```
|
|
|
|
Private images go under `blumeops/*` namespace. Example: the devpi container is at `registry.ops.eblu.me/blumeops/devpi:latest`.
|
|
|
|
### Security Model
|
|
|
|
**Network access only** - no authentication configured. Anyone who can reach zot via Tailscale ACL can push/pull any image. Defense is the tailnet boundary.
|
|
|
|
Zot supports htpasswd/LDAP/OIDC auth if needed in the future.
|
|
|
|
## Minikube Integration
|
|
|
|
The [[minikube]] cluster uses zot as a registry mirror via containerd configuration. Managed by the ansible `minikube` role.
|
|
|
|
From inside minikube, zot is at `host.minikube.internal:5050`. Containerd tries the mirror first, falls back to upstream if not cached.
|
|
|
|
Mirrors configured for: `registry.ops.eblu.me`, `docker.io`, `ghcr.io`, `quay.io`
|
|
|
|
## Useful Commands
|
|
|
|
```bash
|
|
# List all cached/pushed images
|
|
curl -s http://indri:5050/v2/_catalog | jq
|
|
|
|
# List tags for an image
|
|
curl -s http://indri:5050/v2/blumeops/devpi/tags/list | jq
|
|
|
|
# Check service status
|
|
ssh indri 'launchctl list | grep zot'
|
|
|
|
# View logs
|
|
ssh indri 'tail -f ~/Library/Logs/mcquack.zot.err.log'
|
|
```
|
|
|
|
## Log
|
|
|
|
### 2026-01-25
|
|
- **Migrated from Tailscale serve to Caddy** - now accessible at `registry.ops.eblu.me`
|
|
- Retired `tailscale_serve` ansible role (no longer needed)
|
|
- Updated minikube containerd config to use new URL
|
|
- Updated CI workflows and mise tasks
|
|
- Old URL (`registry.tail8d86e.ts.net`) deprecated
|
|
|
|
### 2026-01-21
|
|
- Verified full workflow: podman build on gilbert → push to zot → k8s pull
|
|
- Documented security model (network-only auth via Tailscale ACL)
|
|
- Updated minikube integration: now uses containerd (docker driver) instead of CRI-O (podman driver)
|
|
- Mirror endpoint changed from `host.containers.internal:5050` to `host.minikube.internal:5050`
|
|
|
|
### 2026-01-19
|
|
- Integrated with minikube as CRI-O registry mirror
|
|
- All k8s image pulls now go through zot cache automatically
|
|
|
|
### 2026-01-18
|
|
- Initial setup for k8s migration Phase 0
|
|
- Configured pull-through cache for Docker Hub, GHCR, Quay
|
|
- Exposed via Tailscale service at registry.tail8d86e.ts.net
