What is K8s Rolling Updates and Rollback ?
- Kubernetes Rolling Updates gradually replace older application instances with newer ones to ensure continuous availability. Rollbacks allow reverting to a previous version in case of deployment issues, maintaining system reliability.
- In simpler words, Think of Kubernetes Rolling Updates like renovating a house while still living in it. Instead of shutting down the entire house, you update one room at a time, ensuring you always have a place to stay. Similarly, Rolling Updates in Kubernetes let you update parts of your application without taking it offline, ensuring continuous service for your users.
- Now, imagine you painted a room the wrong color or installed a faulty appliance during the renovation. Rollbacks in Kubernetes are like having a magical undo button. If something goes wrong with the update, you can quickly go back to the previous version, keeping your application running smoothly without any hiccups.
