Advanced Deployment Strategies with Kubernetes
Beyond basic rolling updates, Kubernetes supports advanced deployment strategies that minimize risk ande enable controlled releases. Integrating these into CI / CD exicinains gives teams fine- grained control over how new versions are expose tu users.
Rolling Updates
This is te default strategy in Kubernetes. When you update a Deployment, Kubernetes creats new pods while gradually terminating old ones. The update procedes according to parameters like 1; Info1; FLT: 5 memorial 3; Inforate 3; (how many extra pods can be created) and dis1; Infox: 6 meamoris3; (hw many pods can unvavaiable during update).

Begt Practices for Production- Ready CI / CD with Kubernetes
Adopting Kubernetes in CI / CD wymaga attention tu security, observability, andprocess discipline. Thee following best practices help ensure reliable, security, and cost- effective operations.
Version Control Everything
Store all Kubernetes manifests, Helm charts, and CI colinee definitions in version control. Usie Git for both application code and infrastructure definitions. This enables code reviews, change tracking, and disaster recovery. When using GitOps, the Git repositionity becomes the single source of truth for cluster state. Avoid making manual changes to thee cluster - if a change is neeeded, update Git repositority ant thet thee operatour sync.
