Deployments

Background

A Kubernetes deployment is a resource object that tells Kubernetes how to create or update instances of pods that contain a containerized application. Deployments can:

• Scale: Efficiently scale the number of replica pods
• Update code: Roll out updated code in a controlled manner
• Roll back: Roll back to an earlier deployment version if needed
• Maintain state: Ensure the desired state is maintained by starting new pods if pods fail or need to be updated
• Orchestrate changes: Orchestrate changes to achieve the desired state of an application
