函数计算构建的镜像 访问报错，怎么处理？

当Custom Runtime的bootstrap文件是Shell脚本，且出现以下错误时，Custom Runtime的bootstrap文件一定要添加#!/bin/bash。

{
"ErrorCode":"CAExited",
"ErrorMessage":"The CA process either cannot be started or exited:ContainerStartDuration:25037266905. CA process cannot be started or exited already: rpc error: code = 106 desc = ContainerStartDuration:25000000000. Ping CA failed due to: dial tcp 21.0.XX.XX:9000: i/o timeout Logs : 2019-11-29T07:27:50.759658265Z panic: standard_init_linux.go:178: exec user process caused \"exec format error\"
}
如果是二进制可执行文件，例如Go、C++直接编译出来的目标二进制文件，则不需要添加#!/bin/bash。
