When you work with a lot of Kubernetes clusters each with lots of namespaces, it gets very difficult to manage them.
There’s a great tool called kubectx which helps with that - it’s cross-platform and it lets you easily switch between clusters, along with the partner tool kubens for switching namespaces.
They are very useful tools as you use Kubernetes more, you can install them from the releases, or with:
# Windows
choco install kubectx kubens
# macOS
brew install kubectx kubens
Then use to manage namespaces like this:
# list all namespaces
kubens
# switch to pi
kubens pi
# toggle back to the previous namespace:

I have aliases in all my shells:
alias d="docker"
alias k="kubectl"
alias kx="kubectx"
alias kn="kubens"
So my typical workflow is:
kx <client-cluster>
kn <namespace>
k etc.
