# Fuzzy matches available kubernetes context names for fast context switching
# E.g. if "my-context2" is the only context with "2" in its name, `chctx 2` will switch to it
# Optional second argument to switch namespace at the same time using chns
# Author: Katrina Verey (github.com/KnVerey)
# Suggestion: Add the following to your zshrc and install the completions
# To get fast namespace listing and switching via context names
# Warning: Think through your context names first. E.g. if you're using minikube, you'll need to exclude or unalias it
# or else you'll have a conflict with the executable
#
# local contexts; contexts=($(kubectl config get-contexts -o name))
# for context in $contexts; do
# alias $context="chctx $context"
# done
