Deploy Applications

Deployment workflow

1. Commit manifests or chart values to Git.
2. Define namespace and runtime requirements.
3. Sync with Argo CD.
4. Validate readiness and traffic behavior.
5. Monitor post-deploy health.

Minimal production checklist

• Workload has liveness/readiness probes.
• Resource requests and limits are set.
• Service and route definitions are versioned in Git.
• Rollback method is documented.

Deployment example

apiVersion: apps/v1
kind: Deployment
metadata:
  name: api
  namespace: app-prod
spec:
  replicas: 3
  selector:
    matchLabels:
      app: api
  template:
    metadata:
      labels:
        app: api
    spec:
      containers:
        - name: api
          image: ghcr.io/your-org/api:1.2.3
          ports:
            - containerPort: 8080
          resources:
            requests:
              cpu: "200m"
              memory: "256Mi"
            limits:
              cpu: "1"
              memory: "1Gi"
          readinessProbe:
            httpGet:
              path: /ready
              port: 8080
            periodSeconds: 5

Post-deploy validation

• kubectl get deploy,pods -n <namespace> shows healthy rollout.
• Argo CD app status is Healthy and Synced.
• Dashboard latency and error-rate remain within normal range.
