Example

Rolling updates for zero-downtime deployments

Scenario

Imagine deploying a new version of a web application. Kubernetes can roll out updates incrementally, updating a few pods at a time with the new version, while still serving traffic with the remaining old versions. This ensures that the service remains available even as the update takes place.

Example

Exposing a set of running containers as a single service

Scenario

A microservices architecture where each microservice runs in a separate set of containers. Kubernetes assigns a unique IP address to each service and can distribute network traffic among these services automatically, based on the deployment configuration. This simplifies the discovery of services and balances the load efficiently.

Example

Automatically adding/removing pods based on demand

Scenario

An e-commerce website experiences a sudden surge in traffic during a sale. Kubernetes can automatically increase the number of pods hosting the website to handle the increased load, and then scale them back down once the traffic spike subsides, ensuring resource efficiency.

Example

Automatically replacing failed containers

Scenario

If a container in a pod crashes, Kubernetes detects the failure and automatically restarts the container. This ensures that the application remains available to users, even in the case of software or hardware failures.

Example

Managing sensitive information securely

Scenario

Kubernetes allows the secure storage and management of sensitive information, such as passwords, OAuth tokens, and SSH keys. This enables applications to access the necessary secrets and configurations without hard-coding them into the application or container image, enhancing security.
