Features
This repository provides both kubectx and kubens tools.
kubectx helps you switch between clusters back and forth:
kubens helps you switch between Kubernetes namespaces smoothly:
Docker Usage
Build the docker image using provided Dockerfile and use it directly for example in a local minikube K8s cluster:
docker run -it --rm \
-v "$($HOME/.kube)":/root/.kube/ \
-v "$($HOME/.minikube)":/root/.minikube/ \
binbash/k8s-kubectx:v1.12.10
NOTE: Check docker image tags which will correspond with the proper K8s version you're currently running:
- DOCKER_TAG =
v1.11.xx - DOCKER_TAG =
v1.12.xx - DOCKER_TAG =
v1.13.xx - DOCKER_TAG =
v1.14.xx - DOCKER_TAG =
v1.15.xx
Test Execution
- Interactively run the container
docker run -it --rm \
-v ~/.kube:/root/.kube \
-v ~/.minikube:/root/.minikube \
-e "KUBECONFIG=/root/.kube/config" \
--entrypoint=bash \
binbash/k8s-kubectx:v1.12.10
