Bootstrap Sequence (summary)

# Full plan in ~/dryad-phase7-talos-plan.md

# 1. Inventory — SSH to switch, dump MAC table
ssh admin@10.10.10.2
show switch mac-address-table

# 2. Generate secrets on madhatter (BACK UP IMMEDIATELY — R13)
talosctl gen secrets -o ~/dryad-cluster/secrets.yaml
cp ~/dryad-cluster/secrets.yaml /mnt/backups/dryad-cluster-secrets.yaml

# 3. Generate machine configs
talosctl gen config dryad-cluster https://10.10.10.100:6443 \
  --with-secrets ~/dryad-cluster/secrets.yaml \
  --output-dir ~/dryad-cluster/

R11 · R12 · R13Cluster nodes have NO Tailscale. talosctl is the ONLY management tool (no SSH). secrets.yaml must be backed up offsite before bootstrap.
