这是我的Dockerfile：

FROM gcr.io/distroless/static:nonroot
WORKDIR /
COPY ls .
COPY tail .
COPY test .
COPY manager .
ENTRYPOINT ["/manager"]

后

[root@master go-docker-test]# docker build -t strangething:v1.13 .
[root@master go-docker-test]# docker run -d strangething:v1.13
[root@master go-docker-test]# docker logs b2

它显示：

exec /manager: no such file or directory

我很确定它就在那里。我用潜水来看它：

这个文件树或多或少让我感到困惑。
不管怎样，奇怪的是，ls tail manager不能执行，但test可以执行。
在我将ENTRYPOINT ["/manager"]更改为ENTRYPOINT ["/test"]之后：

[root@master go-docker-test]# docker logs c11
empty

test是由test.go编写的程序，我自己写的：

package main

import (
        "fmt"
)
type Per struct {
        Name string
        Age int
}
type Person struct {
        Name string
        Age int
        Lov Per
}

func main() {
        var one Person
        one.Name="abc"
        one.Age=11
        var two Per
        one.Lov=two
        if one.Lov != (Per{}){
                fmt.Println("not empty!")
        }else {
                fmt.Println("empty")
        }
}
