如何通过Linux Cron Job/Kubernetes cron job从k8s中删除被逐出的pod

import subprocess

def delete_evicted_pods():
    # 使用kubectl命令获取被逐出的pod列表
    cmd = "kubectl get pods --field-selector=status.phase=Failed -o json | jq '.items[] | select(.status.reason!=null) | .metadata.name'"
    process = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    stdout, stderr = process.communicate()

    if process.returncode == 0:
        # 解析获取到的pod名称列表
        pod_names = stdout.decode().strip().split("\n")

        # 逐个删除被逐出的pod
        for pod_name in pod_names:
            delete_cmd = f"kubectl delete pod {pod_name}"
            subprocess.run(delete_cmd, shell=True)
    else:
        print("Failed to get evicted pods:", stderr.decode())

delete_evicted_pods()
