If an uncaughtException occurs in Docker container running node app which is wrapped by Kubernetes Pod and due to this exception the server gets down, what should I do?

CodePudding user response：

If you use ReplicaSet (Deployment is also a ReplicaSet), then after the application crashes, the pod will also crash, as a result of which the ReplicaSet will create a new pod.

PS: I think it's obvious that uncaughtException occurs when there are uncaught exceptions in your code (not in promises and async/await). To prevent this event from being raised, you need to add exception handlers wherever exceptions might be thrown.
