In Kubernetes, the default namespace is the namespace where all resources are created if a namespace is not specified during resource creation. Deploying Pods in the default namespace is not recommended as it can lead to namespace pollution and difficulty in managing and monitoring resources. Therefore, it is important to ensure that Pods are not deployed in the default namespace. Namespace segregation helps in isolating resources and provides better control over them. It also makes it easier to apply policies and security configurations to a specific namespace rather than the entire cluster. Therefore, it is best practice to create a separate namespace for each application or environment.
To ensure Pods are not deployed in the default namespace in Kubernetes, follow these remediation steps:
5. Replace <namespace-name> with the name of the new namespace.
6. Set the new namespace as the default namespace by running the following command:
kubectl config set-context $(kubectl config current-context) --namespace=<namespace-name>
By following these steps, you can ensure that all your Pods are deployed to the correct namespace and avoid potential issues with deployments in the default namespace.
