kubectl get pods -n dev
# Install kubens (part of kubectx) git clone https://github.com/ahmetb/kubectx /opt/kubectx ln -s /opt/kubectx/kubens /usr/local/bin/kubens
Use Short-Lived Contexts: Avoid staying in the "kube-system" or "production" namespaces longer than necessary. kubectl change namespace
By following these steps and best practices, you'll be able to efficiently manage multiple namespaces with kubectl .
kubectl get namespaces
(if installed)
Before we dive into changing namespaces, let's quickly review what namespaces are in Kubernetes. A namespace is a way to group resources, such as pods, services, and deployments, into a logical partition. This allows multiple teams or users to share the same cluster without conflicts. kubectl get pods -n dev # Install kubens
The kubectl change namespace command is the primary way to switch the context of your Kubernetes operations between different logical partitions of your cluster. While there is no single "change" command, several methods allow you to pivot your active namespace quickly.
