问题：跟往常一样执行docker-compos exec redis sh时出现如下错误，而容器是运行状态中。
# docker-compose exec redis sh rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "process_linux.go:75: starting setns process caused \"fork/exec /proc/self/exe: no such file or directory\""
