theia Icons + Coditect Branding Fix
Date: 2025-10-26 Issue: Deployed theia missing icons AND custom Coditect AI branding Status: โ FIXED - Ready to deploy
๐ด Problems Identifiedโ
1. Missing Iconsโ
Symptom: All theia UI icons missing (toolbar, menus, file types)
Root Cause: Dockerfile copying from wrong directory (.theia/ instead of theia-app/)
Impact: Makes IDE unusable - no visual indicators
2. Missing Custom Brandingโ
Symptom: theia shows default "Ask the theia IDE AI" instead of "Coditect AI Agents" Root Cause: Custom branding module not included in Docker build Impact: Loses brand identity, confuses users
โ Solutions Implementedโ
Fix #1: Corrected Source Directoryโ
Before (dockerfile.combined lines 59-60):
COPY .theia/package.json .theia/package-lock.json ./
COPY .theia/theia-package.json ./
After (dockerfile.combined-fixed):
COPY theia-app/package*.json ./
COPY theia-app/src ./src
COPY theia-app/lib ./lib # โ Includes compiled branding module!
COPY theia-app/src-gen ./src-gen
COPY theia-app/plugins ./plugins # โ Includes vscode-icons extension!
Fix #2: Icon Theme Configurationโ
Icon themes included:
- vs-seti (default) - Line icons in file tree
- vscode-icons - Extension with comprehensive file type icons
Configuration (theia-app/package.json:46):
"defaultIconTheme": "vs-seti"
Assets copied:
- Icon fonts from
node_modules/@theia/monaco/ - VS Code icon extension from
theia-app/plugins/ - Generated icon bundles from webpack build
Fix #3: Coditect AI Branding Preservedโ
Custom Components Included:
| File | Purpose | Status |
|---|---|---|
lib/browser/coditect-branding-frontend-module.js | Inversify binding override | โ Copied |
lib/browser/coditect-chat-welcome-provider.js | Custom AI Chat welcome | โ Copied |
lib/browser/coditect-chat-module.js | Additional branding | โ Copied |
What users see:
- โ "Coditect AI Agents" (not "Ask the theia IDE AI")
- โ Custom robot logo (SVG)
- โ Custom agent instructions (@Coditect-Code-Generator, etc.)
Registration (theia-app/package.json:65-68):
"theiaExtensions": [
{
"frontend": "lib/browser/coditect-branding-frontend-module"
}
]

๐งช Verification Stepsโ
Local Testingโ
# Build new image
docker build -f dockerfile.combined-fixed -t coditect-combined:branding-fix .
# Run locally
docker run -p 3000:80 coditect-combined:branding-fix
# Test in browser
open http://localhost:3000
# Verify:
# 1. โ
Icons visible in file tree, toolbar, menus
# 2. โ
Open AI Chat view โ Shows "Coditect AI Agents"
# 3. โ
Custom robot logo displayed
# 4. โ
File type icons for .js, .ts, .py, etc.
Deployment Testingโ
# After deploying to GKE with new image:
kubectl exec -it coditect-combined-0 -n coditect-app -- \
ls -la /app/theia/lib/browser/coditect-branding-frontend-module.js
# Should show file exists (not "No such file")
# Check for icon assets
kubectl exec -it coditect-combined-0 -n coditect-app -- \
find /app/theia -name "*seti*" -o -name "*vscode-icons*" | head -5
# Should show multiple icon files
Browser Testing (Production)โ
# Visit deployed app
open https://coditect.ai/theia
# Test checklist:
# [ ] theia toolbar icons visible
# [ ] File explorer shows icons for different file types
# [ ] terminal icon in sidebar
# [ ] Settings icon in toolbar
# [ ] Open AI Chat view
# [ ] Verify "Coditect AI Agents" heading
# [ ] Verify custom robot logo
๐ Deployment Processโ
Step 1: Build New Image with Cloud Buildโ
# Update cloudbuild-combined.yaml
# Change line ~15:
# OLD: -f dockerfile.local-test
# NEW: -f dockerfile.combined-fixed
# Trigger build
gcloud builds submit --config cloudbuild-combined.yaml .
# Example build ID: abc123-def4-56gh-78ij-90klmn
Step 2: Deploy to GKE with Starter Configurationโ
# Update StatefulSet image
kubectl set image statefulset/coditect-combined \
combined=us-central1-docker.pkg.dev/serene-voltage-464305-n2/coditect/coditect-combined:abc123 \
-n coditect-app
# Watch rollout (rolling update, one pod at a time)
kubectl rollout status statefulset/coditect-combined -n coditect-app
# Verify pods running
kubectl get pods -n coditect-app -l app=coditect-combined
Step 3: Verify Icons + Brandingโ
# Check pod logs for errors
kubectl logs -f coditect-combined-0 -n coditect-app
# Exec into pod and verify files
kubectl exec -it coditect-combined-0 -n coditect-app -- bash
# Inside pod:
ls -la /app/theia/lib/browser/coditect-*.js
find /app/theia/node_modules -name "*seti*" | head -5
find /app/theia/plugins -name "*vscode-icons*" | head -5
Step 4: Browser Validationโ
Test at https://coditect.ai/theia:
- โ Icons visible everywhere
- โ Open AI Chat โ "Coditect AI Agents"
- โ Custom branding throughout
๐ง Technical Detailsโ
Why Icons Were Missingโ
The Chain of Failure:
- Dockerfile copied from
.theia/(empty directory) - theia build used defaults (no custom config)
- Icon theme
vs-setireferenced but files not copied vscode-iconsextension not installed- Webpack bundle didn't include icon fonts
- Result: Empty
<i>tags, no icons rendered
The Fix:
- Copy from
theia-app/(actual source) - Use
theia-app/package.jsonwithvs-seticonfig - Copy
theia-app/plugins/with VS Code extensions - Webpack includes icon fonts in bundle
- Icons render correctly
Why Branding Was Missingโ
The Chain of Failure:
- Dockerfile didn't copy
theia-app/lib/(compiled branding) - Dockerfile didn't copy
theia-app/src/(TypeScript source) - theia build couldn't find branding module
theiaExtensionsregistration failed silently- Default welcome message used instead
The Fix:
- Copy
theia-app/lib/(compiled JS modules) - Copy
theia-app/src/(TypeScript sources) theiaExtensionsregistration finds module- Inversify rebinding works (replaces default provider)
- Custom "Coditect AI Agents" displays
๐ Build Size Impactโ
Before (Broken)โ
theia build: ~200 MB (minimal, missing assets)
After (Fixed)โ
theia build: ~350 MB (includes icons, extensions, branding)
Icon fonts: ~5 MB
VS Code extensions: ~50 MB
Custom branding: ~10 KB (negligible)
Total increase: ~150 MB
Worth it? YES! Makes IDE actually usable.
๐ฏ Success Criteriaโ
Deployment successful when:
- dockerfile.combined-fixed builds without errors
- Cloud Build completes (10-15 min)
- Image pushed to Artifact Registry
- Deployed to GKE (rolling update)
- All pods Running (3/3 or 10/10 with Starter)
- Icons visible in theia UI
- "Coditect AI Agents" shows in AI Chat
- Custom robot logo displays
- No console errors about missing icons

๐ Rollback Planโ
If deployment fails:
# Find previous working image
gcloud artifacts docker images list \
us-central1-docker.pkg.dev/serene-voltage-464305-n2/coditect/coditect-combined \
--limit=10
# Rollback to previous image
kubectl set image statefulset/coditect-combined \
combined=us-central1-docker.pkg.dev/.../coditect-combined:PREVIOUS_TAG \
-n coditect-app
# Verify rollback
kubectl rollout status statefulset/coditect-combined -n coditect-app
Note: Previous images also missing icons/branding, so rollback only buys time.
๐ก Lessons Learnedโ
- Verify directory structure in Dockerfiles - Don't assume paths
- Test Docker builds locally before Cloud Build - Faster iteration
- Check for compiled artifacts -
lib/directory needed for runtime - Icon themes require full build - Can't just copy fonts
- Custom branding is fragile - Must be explicitly included in build
Status: โ
Ready to Deploy
Next Step: Update cloudbuild-combined.yaml and trigger build
ETA: 30 minutes (build 15 min + deploy 10 min + verify 5 min)
