Podman指定--entrypoint时crun报错：可执行文件未找到

我正尝试在Podman中复现基于mlflow/minio的环境，该环境在VM中通过docker-compose可正常运行。但在Podman中，通过--entrypoint参数执行自动创建MinIO存储桶的脚本时，反复出现如下错误：
Error: crun: executable file [/bin/sh,-c,/create_bucket.sh] not found in $PATH: No such file or directory: OCI runtime attempted to invoke a command that was not found

相关配置 #

create_bucket.sh脚本 #

#!/bin/sh
sleep 5;
/usr/bin/mc config host add mlflow_minio_storage http://mlflow_minio_storage:9000 "$MINIO_ACCESS_KEY" "$MINIO_SECRET_ACCESS_KEY" --api S3v4;
/usr/bin/mc ls mlflow_minio_storage | grep -q challenge || /usr/bin/mc mb mlflow_minio_storage/mlflow;
/usr/bin/mc policy download mlflow_minio_storage/mlflow;
exit 0;

Containerfile（Dockerfile） #

FROM docker.io/minio/mc

COPY create_bucket.sh /create_bucket.sh
RUN chmod +x /create_bucket.sh

Podman运行命令 #

podman build -t minio_client:latest -f Containerfile
podman run \
--name=mlflow_minio_client \
--detach \
--secret=MINIO_ACCESS_KEY,type=env,target=MINIO_ACCESS_KEY \
--secret=MINIO_SECRET_ACCESS_KEY,type=env,target=MINIO_SECRET_ACCESS_KEY \
--net mlflow_net \
--network-alias mlflow_minio_client \
--restart always \
--requires mlflow_minio_storage \
--entrypoint ["/bin/sh","-c","/create_bucket.sh"] \
localhost/minio_client:latest

最小复现示例 #

即使是简化后的命令也会触发相同错误：

podman run \
--entrypoint ["/bin/sh","-c","/usr/bin/mc version"] \
docker.io/minio/mc:latest

对应的报错信息：
Error: crun: executable file [/bin/sh,-c,/usr/bin/mc version] not found in $PATH: No such file or directory: OCI runtime attempted to invoke a command that was not found

疑问 #

我是否误解了--entrypoint的使用方式？
