## 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

# Minikube Management Log
|
|
|
|
Minikube provides a single-node Kubernetes cluster on Indri for running containerized services.
|
|
|
|
## Cluster Details
|
|
|
|
- Driver: **docker** (runs as container inside Docker Desktop)
|
|
- Container runtime: docker
|
|
- Kubernetes version: v1.34.0
|
|
- Resources: 6 CPUs, 11GB RAM (leaves 1GB for Docker Desktop overhead), 200GB disk
|
|
- API server: https://k8s.tail8d86e.ts.net (Tailscale service with TCP passthrough)
|
|
- Internal port: dynamic (currently 50820 - Docker maps random host port to container's 6443)
|
|
|
|
**Prerequisites:** Docker Desktop must be installed and running with at least 12GB memory allocated.
|
|
|
|
## Remote Access from Gilbert
|
|
|
|
Run `mise run ensure-minikube-indri-kubectl-config` to set up kubectl access. This script:
|
|
1. Fetches certificates from indri via SSH
|
|
2. Creates kubeconfig at `~/.kube/minikube-indri/config.yml`
|
|
|
|
**Fish abbreviations** (in `~/.config/fish/config.fish`):
|
|
- `ki` -> `kubectl --context=minikube-indri`
|
|
- `k9i` -> `k9s --context=minikube-indri`
|
|
- `k9` -> `k9s`
|
|
|
|
```bash
|
|
# Quick access via abbreviations
|
|
ki get nodes
|
|
k9i
|
|
|
|
# Or explicitly set context
|
|
kubectl config use-context minikube-indri
|
|
kubectl get nodes
|
|
```
|
|
|
|
## Volume Mounting (for P6 kiwix/transmission)
|
|
|
|
**Direct NFS from pods to sifaka** - tested and working.
|
|
|
|
Docker NATs outbound traffic through indri's LAN IP (192.168.1.50). Sifaka's NFS exports allow:
|
|
- `192.168.1.0/24` - Docker containers via indri NAT
|
|
- `100.64.0.0/10` - Tailscale clients
|
|
|
|
Pods mount NFS directly:
|
|
```yaml
|
|
volumes:
|
|
- name: torrents
|
|
nfs:
|
|
server: sifaka
|
|
path: /volume1/torrents
|
|
```
|
|
|
|
No LaunchAgents, no `minikube mount`, no hostPath complexity needed.
|
|
|
|
## Useful Commands (on indri)
|
|
|
|
```bash
|
|
# Cluster status
|
|
minikube status
|
|
|
|
# Start/stop cluster
|
|
minikube start
|
|
minikube stop
|
|
|
|
# Access dashboard
|
|
minikube dashboard
|
|
|
|
# SSH into node
|
|
minikube ssh
|
|
|
|
# View logs
|
|
minikube logs
|
|
|
|
# Get API server URL (shows current port)
|
|
kubectl config view --minify -o jsonpath="{.clusters[0].cluster.server}"
|
|
```
|
|
|
|
## Registry Mirror (Zot)
|
|
|
|
Containerd is configured to use [[zot]] on indri as a pull-through cache for container images. This is managed by the ansible `minikube` role.
|
|
|
|
Config location: `/etc/containerd/certs.d/<registry>/hosts.toml` (inside minikube container)
|
|
|
|
With docker driver, uses `host.minikube.internal:5050` to reach zot on the host.
|
|
|
|
Mirrors configured for:
|
|
- `registry.ops.eblu.me` (private images)
|
|
- `docker.io`
|
|
- `ghcr.io`
|
|
- `quay.io`
|
|
|
|
To verify the mirror is working:
|
|
```bash
|
|
# Check zot's cached images
|
|
curl -s http://localhost:5050/v2/_catalog | jq
|
|
```
|
|
|
|
## Log
|
|
|
|
### 2026-01-21 (Docker Driver Migration)
|
|
- **Migrated from qemu2 to docker driver** (Phase 5.1)
|
|
- qemu2 had Tailscale TCP proxy issue (TLS handshake timeout to VM IP)
|
|
- docker driver puts API server on localhost, which Tailscale serve handles correctly
|
|
- Removed socket_vmnet, qemu dependencies
|
|
- Removed NFS/minikube-mount LaunchAgents (will re-add NFS for P6 with simpler hostPath approach)
|
|
- API server port is now dynamic (Docker assigns random host port)
|
|
- Ansible role updated to query port and configure tailscale serve accordingly
|
|
- Created `mise run ensure-minikube-indri-kubectl-config` for workstation setup
|
|
|
|
### 2026-01-21 (QEMU2 Migration - superseded)
|
|
- Migrated from podman to qemu2 driver
|
|
- Podman driver had fundamental limitations preventing volume mounts
|
|
- qemu2 created actual VM with full kernel capabilities
|
|
- Volume mounting solution: NFS on host + minikube mount passthrough
|
|
- **Issue discovered:** Tailscale TCP proxy to VM IP (192.168.105.2:6443) fails with TLS timeout
|
|
|
|
### 2026-01-19
|
|
- Configured CRI-O registry mirror to use zot as pull-through cache
|
|
- Added ansible automation to apply mirror config on provisioning
|
|
- Fixed ansible hanging: `minikube ssh` with piped stdin requires `--native-ssh=false`
|
|
|
|
### 2026-01-18
|
|
- Initial cluster setup for k8s migration Phase 0
|
|
- Configured for remote access with --apiserver-names=indri
|
|
- 1Password credential integration for kubectl from gilbert
|
|
- Exposed as Tailscale service `k8s.tail8d86e.ts.net` with TCP passthrough
