3. Deployment

✅ Built Docker image with new code
✅ Image tagged as icn:0bf1f61 (git hash)
⚠️ Deployment blocked by K3s imagePullPolicy issue

🚧 Blocking Issue

K3s Image Pull Problem

Symptom: ErrImageNeverPull or ImagePullBackOff

Root Cause:
K3s with containerd doesn't properly recognize manually imported images when using imagePullPolicy: Never or IfNotPresent.

Images Available:

Local Docker: icn:0bf1f61 ✅
K3s containerd: docker.io/library/icn:0bf1f61 ✅
Deployment spec: docker.io/library/icn:0bf1f61 ✅

BUT: Kubernetes still can't find the image!

Attempted Solutions

❌ kubectl rollout restart - used old cached image
❌ kubectl delete pod - forced restart but still old image
❌ kubectl set image with icn:0bf1f61 - ErrImageNeverPull
❌ kubectl set image with docker.io/library/icn:0bf1f61 - ErrImageNeverPull
❌ Changed imagePullPolicy to IfNotPresent - ImagePullBackOff
❌ Manual ctr images import - image shows in list but K8s can't see it
❌ kubectl rollout undo - reverted to broken state

🔧 Required Fixes

Option 1: Fix K3s Image Configuration (RECOMMENDED)

Problem: K3s containerd CRI configuration may not be set up correctly for local images.

Solution:

# On K3s node
sudo vim /etc/rancher/k3s/registries.yaml

# Add:
mirrors:
  docker.io:
    endpoint:
      - "https://registry-1.docker.io"
configs:
  "docker.io":
    auth:
      username: ""
      password: ""

# Restart K3s
sudo systemctl restart k3s

Option 2: Use Image Registry (ALTERNATIVE)

Setup local registry or use Docker Hub:

# Option A: Local registry
docker run -d -p 5000:5000 --name registry registry:2
docker tag icn:0bf1f61 localhost:5000/icn:0bf1f61
docker push localhost:5000/icn:0bf1f61

# Update deployment
kubectl set image deployment/icn-daemon -n icn \
  icnd=localhost:5000/icn:0bf1f61

# Option B: Docker Hub
docker tag icn:0bf1f61 username/icn:0bf1f61
docker push username/icn:0bf1f61

Option 3: Direct Binary Deployment (QUICK FIX)

Skip Docker, copy binary directly:

# Build binary
cd icn && cargo build --release --bin icnd

# Copy to K3s node
scp target/release/icnd ubuntu@10.8.10.40:/tmp/

# On K3s node, replace binary in running pod
POD=$(sudo kubectl get pods -n icn -l component=daemon -o jsonpath='{.items[0].metadata.name}')
sudo kubectl cp /tmp/icnd icn/$POD:/usr/local/bin/icnd
sudo kubectl exec -n icn $POD -- killall -HUP icnd

📊 What's Ready to Test

Once deployment is fixed, these endpoints are ready:

# 1. Health check (already working)
curl http://10.8.10.40:30080/v1/sdis/health

# 2. Start enrollment (NEW)
curl -X POST http://10.8.10.40:30080/v1/sdis/enrollment/start \
  -H "Content-Type: application/json" \
  -d '{"identity_name":"Alice","coop_id":"test-coop"}'

# Expected response:
{
  "enrollment_id": "uuid...",
  "verification_code": "VERIFY-1234",
  "qr_code": "data:image/png;base64,...",
  "expires_at": "2025-12-13T22:00:00Z"
}

# 3. Level 1 verification (NEW)
curl -X POST http://10.8.10.40:30080/v1/sdis/verify/level1 \
  -H "Content-Type: application/json" \
  -d '{"enrollment_id":"uuid...","device_proof":"base64..."}'

# 4. Level 2 verification (NEW)
curl -X POST http://10.8.10.40:30080/v1/sdis/verify/level2 \
  -H "Authorization: Bearer <steward-token>" \
  -H "Content-Type: application/json" \
  -d '{"enrollment_id":"uuid...","vouch_statement":"I vouch for Alice"}'

# 5. Complete enrollment (NEW)
curl -X POST http://10.8.10.40:30080/v1/sdis/enrollment/complete \
  -H "Content-Type: application/json" \
  -d '{
    "enrollment_id":"uuid...",
    "ephemeral_did":"did:icn:z...",
    "ephemeral_signature":"base64...",
    "device_info":{"device_type":"smartphone","os":"Android","app_version":"1.0.0"}
  }'

# Expected response:
{
  "did": "did:icn:z...",
  "recovery_codes": ["CODE1", "CODE2", "CODE3", "CODE4", "CODE5"],
  "auth_token": "Bearer ..."
}

🎯 Next Steps

Immediate (Fix Deployment)

SSH to K3s node:
```
ssh ubuntu@10.8.10.40
```

Check current deployment:

sudo kubectl get pods -n icn
sudo kubectl describe pod -n icn <pod-name>

Try Option 3 (Direct Binary) - quickest fix

# On local machine
cd /home/matt/projects/icn/icn
cargo build --release --bin icnd
scp target/release/icnd ubuntu@10.8.10.40:/tmp/

# On K3s node
POD=$(sudo kubectl get pods -n icn -l component=daemon -o jsonpath='{.items[0].metadata.name}')
sudo kubectl cp /tmp/icnd icn/$POD:/usr/local/bin/icnd
sudo kubectl delete pod -n icn $POD  # Force restart

Once Deployed

Test enrollment flow end-to-end
Verify all SDIS endpoints work
Update Pilot UI to use new endpoints
Test mobile app integration

💡 Key Learnings

K3s + Containerd: Requires careful attention to image pull policies and registry configuration
Git Hash Tagging: Deployment uses git commit hashes, not :latest tag
Image Import: ctr images import alone isn't enough - K8s CRI needs proper config
Rollout Strategy: Need reliable way to update images in air-gapped K3s environment

📈 Progress Summary

Code: ✅ 100% Complete
Build: ✅ 100% Complete
