Simplifying Context Configuration and Switching in Multiple Kubernetes Clusters

Understanding Contexts in Kubernetes
In Kubernetes, a context refers to a combination of a cluster, a user, and a namespace. Managing contexts becomes challenging when working with multiple clusters, each with its authentication requirements, namespaces, and unique configurations.

Tools to Simplify Kubernetes Context Management

  1. kubectx and kubens: Streamline context switching and namespace navigation.

  2. k9s: A terminal-based UI that facilitates cluster management and context switching.

  3. kubie: Provides shortcuts and aliases for easier context management.

  4. kubectl aliases: Custom aliases can simplify complex commands and context switching.

Switching contexts

To list all Kubernetes contexts.

kubectl config view -o jsonpath='{.contexts[*].name}' | tr " " "\n"
Enter fullscreen mode Exit fullscreen mode

Check your current context.

kubectl config current-context
Enter fullscreen mode Exit fullscreen mode

Switch context from current context.

kubectl config use-context <context_name>
Enter fullscreen mode Exit fullscreen mode

Thank you for reading and happy Kubernetes managing! 🎉👏😊"
