alias kc='kubectl'
alias km='kustomize'
# List used port info and process id
alias lp='function _lp(){ lsof -n -iTCP:$1 | grep LISTEN; };_lp'

alias vscode='open -a /Applications/Visual\ Studio\ Code.app/'

Kubectl

kubectl get [service/pod] 　　# 查看 service 資源, pod 資源
kubectl logs pod [pod-name]  # 查看 pod 相關 logs
kubectl apply -f xxxx.yaml   # 把相關資源部署到 k8s 叢集內
kubectl describe [workload]  # 查看 k8s workload 資源 

alias kc='kubectl'

Autocomplete

source <(kubectl completion zsh)  # setup autocomplete in zsh into the current shell
echo "[[ $commands[kubectl] ]] && source <(kubectl completion zsh)" >> ~/.zshrc # add autocomplete permanently
