使用普通数组（索引从0开始）
GROUP_NAMES=("NACOSService" "MIDService" "APPService")
GROUP_SERVICES=(
"nacos"
"mid01 mid02"

停止状态
STOPPED=("0" "0" "0")
获取某组剩余的 Pod 总数
get_remaining_pods() {
local services=$1
local total=0
for svc in $services; do
local count=(kubectl get pods -n NAMESPACE --no-headers 2>/dev/null | grep "^${svc}" | wc -l)
total=$((total + count))

}
检查是否有 Pod（只要 Pod 还存在就算）
has_pods() {
local services=$1
local remaining=(get_remaining_pods "services")
$remaining -gt 0 && return 0 || return 1
}
停止资源
stop_resource() {

echo " StatefulSet $name"
kubectl scale statefulset name -n NAMESPACE --replicas=0
elif kubectl get deployment name -n NAMESPACE &>/dev/null; then
echo " Deployment $name"
kubectl scale deployment name -n NAMESPACE --replicas=0

}
停止一组
stop_group() {

echo "$name 已经没有 Pod 了"

echo "停止 $name (当前 ${initial_pods} 个 Pod) ..."
并行停止所有资源
for svc in $services; do
stop_resource "$svc" &
done
wait
echo -n " 等待 Pod 终止"
等待所有 Pod 完全消失（包括 Terminating 状态）
while has_pods "$services"; do

echo " 0 完成"
echo "$name 已完全停止"
