With over 650+ attendees, GDG DevFest is one of Pakistan’s biggest developer conferences. In between hosting and managing the event with my team, I also made time to talk about one of my favorite technologies, Kubernetes.
In this session I talk discuss making your application deployments resilient and fault-tolerant. By keeping in mind some important concepts when designing your app, and defining what constitutes good health, you hand over most other responsibilities to Kubernetes which will make sure that your app is always alive and performing optimally.
Here’s the deployment manifest in the demo above:
