• 脚本内容

#!/bin/bash

for i  in {1..100}
do
    deploymentName=deployment-$i
    newYaml=tmp-$i.yaml
    cp test.yaml $newYaml
    sed -ie 's/deployment-/'"$deploymentName"'/g' $newYaml
    echo $newYaml
    kubectl apply -f $newYaml
    rm $newYaml
done

rm tmp-*

批量删除直接把kubectl apply 改为kubectl delete即可
