GitLab CI/CD Quick Reference Card
Last Updated: 2025-10-29
Status: Production Ready
Pipeline: .gitlab-ci.yml (454 lines, 16KB)
Quick Start (3 Steps)
1. Configure Variables (10 min)
# GitLab: Settings > CI/CD > Variables
DOCKER_HUB_USERNAME = jgrusewski # Protected, Masked
DOCKER_HUB_PASSWORD = dckr_pat_... # Protected, Masked (access token!)
Get Docker Hub token: hub.docker.com > Account Settings > Security > New Access Token
2. Push to Main (trigger build)
git add .gitlab-ci.yml GITLAB_CI_*.md
git commit -m "feat(ci): Add GitLab CI/CD Docker build pipeline"
git push origin main
3. Monitor Pipeline (10-15 min)
# GitLab: CI/CD > Pipelines > [latest pipeline]
# Stages: build (2-8 min) → test (5-10 min) → deploy (manual)
Pipeline Overview

Docker Image
Dockerfile: Dockerfile.runpod
Base: nvidia/cuda:12.4.1-cudnn-devel-ubuntu22.04
Size: ~4.8GB
Tags:
- jgrusewski/foxhunt:latest # Latest production
- jgrusewski/foxhunt:a1b2c3d # Specific commit
Registry: Docker Hub (PRIVATE)
Deployment
Option 1: GitLab UI (Manual)
1. CI/CD > Pipelines > [latest] > Deploy stage
2. Click ▶ (play) on deploy:runpod
3. Follow instructions in job output
Option 2: Python Script (Automated)
IMAGE_TAG="jgrusewski/foxhunt:$(git rev-parse --short HEAD)"
python3 scripts/runpod_deploy.py --gpu-type "RTX A4000" --image $IMAGE_TAG
Option 3: Runpod Console (Manual)
Region: EUR-IS-1 (required for volume)
GPU: RTX A4000 (16GB, $0.25/hr)
Image: jgrusewski/foxhunt:latest
Auth: Docker Hub credentials
Volume: /runpod-volume
Validation Tests
GLIBC (Ubuntu 22.04 Compatibility)
docker run --rm jgrusewski/foxhunt:latest ldd --version
docker run --rm jgrusewski/foxhunt:latest ldconfig -p | grep libstdc++
CUDA (12.4.1 + cuDNN 9)
docker run --rm jgrusewski/foxhunt:latest ls /usr/local/cuda/lib64/ | grep libcublas
docker run --rm jgrusewski/foxhunt:latest find /usr -name "libcudnn*"
Entrypoint Scripts
docker run --rm jgrusewski/foxhunt:latest ls -la /entrypoint.sh
docker run --rm jgrusewski/foxhunt:latest --help
Troubleshooting
Build Fails: "unauthorized"
# Cause: Missing/incorrect Docker Hub credentials
# Fix: Verify GitLab CI/CD Variables
- DOCKER_HUB_USERNAME = jgrusewski
- DOCKER_HUB_PASSWORD = dckr_pat_... (access token, NOT password)
Build Fails: "denied: requested access"
# Cause: Repository not accessible
# Fix: Verify Docker Hub repository
- Repository: jgrusewski/foxhunt (must exist)
- Visibility: PRIVATE (required for production)
- Token permissions: Read, Write, Delete
Cache Not Working
# Cause: First build or latest tag missing
# Fix: Run at least one successful build
- First build: ~5-8 min (no cache)
- Subsequent builds: ~2-3 min (cached)
- Cache hit rate improves after 2-3 builds
Test Fails: "binary not found"
# Cause: Binaries on Runpod volume, not in image
# Fix: Expected behavior (binaries validated on Runpod deployment)
- Tests gracefully handle missing binaries
- Message: "Binary not found on volume (expected in CI)"
Commands
Local Validation
# Validate YAML syntax
python3 -c "import yaml; yaml.safe_load(open('.gitlab-ci.yml'))"
# Build image locally
docker build -f Dockerfile.runpod -t jgrusewski/foxhunt:test .
# Test locally
docker run --rm jgrusewski/foxhunt:test ldd --version
docker run --rm jgrusewski/foxhunt:test nvidia-smi # Requires GPU
# Inspect image
docker inspect jgrusewski/foxhunt:latest
docker history jgrusewski/foxhunt:latest | head -10
Docker Hub
# Login
echo "$DOCKER_HUB_PASSWORD" | docker login -u "$DOCKER_HUB_USERNAME" --password-stdin
# List tags
curl -s https://hub.docker.com/v2/repositories/jgrusewski/foxhunt/tags/ | jq .
# Pull specific tag
docker pull jgrusewski/foxhunt:a1b2c3d
GitLab CI/CD
# View pipeline status
git log --oneline --grep="ci:"
# Trigger pipeline (push to main)

Performance
Build Time
| Scenario | Duration | Speedup |
|---|---|---|
| Clean build (no cache) | 5-8 min | - |
| Cached build | 2-3 min | 60-80% faster |
| Test stage | 5-10 min | Parallel execution |
| Total pipeline | 10-15 min | First run |
| Total pipeline | 5-8 min | Subsequent runs |
Cache Hit Rate
# Monitor in build logs
CACHED [1/5] FROM nvidia/cuda:...
CACHED [2/5] RUN apt-get update...
# Target: >80% cache hit rate
Cost
GitLab CI/CD: $0/month (free tier, 400 min/month)
Docker Hub: $0/month (free tier, 1 private repo)
Runpod GPU: $0.004-0.04/training (2-10 min)
Total: ~$0/month (excluding GPU training)
Security
Best Practices
✓ Use Docker Hub access tokens (NOT passwords)
✓ Mark DOCKER_HUB_PASSWORD as Masked (hides in logs)
✓ Mark variables as Protected (main branch only)
✓ Set Docker Hub repository to PRIVATE
✓ Rotate tokens every 90 days
✓ Manual approval for production deployments
✓ Auto-stop staging after 1 hour
Token Management
# Create token: hub.docker.com > Account Settings > Security
# Name: GitLab CI/CD - Foxhunt
# Permissions: Read, Write, Delete
# Expiry: No expiration (rotate manually every 90 days)
