將 kubectl 改成 k 並同時擁有 bash completion 的設定方法

自動修改

kubectl completion bash | sudo tee /etc/bash_completion.d/k > /dev/null
sudo sed -e 's/local commands=("kubectl")/local commands=("k")/g' /etc/bash_completion.d/k -i
sudo sed -e 's/__start_kubectl kubectl/__start_kubectl k/g' /etc/bash_completion.d/k -i
echo 'alias k=kubectl' | tee -a ~/.profile > /dev/null
. ~/.profile

手動修改

1. 先產生 bash completion 檔案

   kubectl completion bash | sudo tee /etc/bash_completion.d/k > /dev/null

2. 編輯 /etc/bash_completion.d/k 檔案內容

   sudo vi /etc/bash_completion.d/k

   在檔案最末端，修改以下 3 個地方：

   • local commands=("kubectl") 改成 local commands=("k")
   • __start_kubectl kubectl 改成 __start_kubectl k (有兩處要改)

   

3. 設定 k 別名

   echo 'alias k=kubectl' | tee -a ~/.profile > /dev/null
   . ~/.profile

# Mac OSX Run this script after upgrade kubectl from brew
VERSION=`kubectl version --short --client | awk -F'Client Version: v' '{print $2}'`
sed -i.bak 's/local commands=("kubectl")/local commands=("k")/g' /usr/local/Cellar/kubernetes-cli/${VERSION}/etc/bash_completion.d/kubectl
sed -i.bak 's/__start_kubectl kubectl/__start_kubectl k/g'       /usr/local/Cellar/kubernetes-cli/${VERSION}/etc/bash_completion.d/kubectl
rm -f /usr/local/Cellar/kubernetes-cli/${VERSION}/etc/bash_completion.d/kubectl.bak
mv /usr/local/Cellar/kubernetes-cli/${VERSION}/etc/bash_completion.d/{kubectl,k}
rm -f /usr/local/etc/bash_completion.d/kubectl
cd /usr/local/etc/bash_completion.d/
ln -s ../../Cellar/kubernetes-cli/${VERSION}/etc/bash_completion.d/k k
cd -
