runtime_env container启动报错

[show]

在k8s中使用runtime_env的docker环境时遇到如下错误：

复现：
1、k8s yaml 将pod拉起

apiVersion: v1
kind: Pod
metadata:
 name: podman-priv
spec:
 containers:
   - name: priv
     image: quay.io/podman/stable
     args:
       - sleep
       - "1000000"
     securityContext:
       privileged: true

2、进入pod，安装ray
3、执行脚本

import ray 
import os

@ray.remote
def test():
    return "hello"

print(ray.get(test.options(runtime_env={"container":
    {"image": "registry.access.redhat.com/ubi8:latest","run_options": ["--cap-drop SYS_ADMIN","--log-level=debug"]}
}).remote()))
