Game Server Deployment

Deploy scalable game servers with containerization and orchestration.

Docker Production Build

FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production
COPY . .
RUN npm run build

FROM node:20-alpine
WORKDIR /app
RUN addgroup -g 1001 -S app && adduser -S app -u 1001
COPY --from=builder --chown=app:app /app/dist ./dist
COPY --from=builder --chown=app:app /app/node_modules ./node_modules
USER app

HEALTHCHECK --interval=30s --timeout=5s \
  CMD wget -q --spider http://localhost:8080/health || exit 1

EXPOSE 7777/udp 8080/tcp
CMD ["node", "dist/server.js"]

Kubernetes Deployment

Auto-Scaling

apiVersion: autoscaling/v2
kind: HorizontalPodAutoscaler
spec:
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: game-server
  minReplicas: 3
  maxReplicas: 100

Troubleshooting

Common Failure Modes

Error	Root Cause	Solution
CrashLoopBackOff	Startup crash	Check logs, config
OOMKilled	Memory exceeded	Increase limits
ImagePullBackOff	Auth failed	Check secrets
Pending	No resources	Scale cluster

Debug Checklist

# Check pods
kubectl get pods -l app=game-server

# Check logs
kubectl logs -l app=game-server --tail=100

# Check events
kubectl get events --sort-by=.lastTimestamp

# Rollback
kubectl rollout undo deployment/game-server

Unit Test Template

# test-deployment.yaml
apiVersion: v1
kind: Pod
metadata:
  name: deployment-test
spec:
  containers:
  - name: test
    image: game-server:test
    command: ["npm", "test"]
  restartPolicy: Never
