Kubernetes Deployment Strategies

Deploying to production requires careful planning. Here's our approach.

Rolling Updates

The default strategy - gradually replace old pods with new ones:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-app
spec:
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 0

Blue-Green Deployments

Maintain two identical environments and switch traffic between them.

Canary Releases

Test new versions with a small subset of users before full rollout.

Best Practices

1. Always use health checks
2. Implement proper monitoring
3. Have a rollback plan
4. Test in staging first

Happy deploying!
