我正在尝试使用 golang 检索 cri-o 信息，例如 containerID、pid。下面提到的代码在我的 mac 中工作，但是当我将它容器化并将其部署在 openshift 3.11 堆栈上时，它不起作用。

cmdStr在下面提到的代码中可以是任何 docker 或 cri-o 命令，例如docker ps或crictl ps --no-trunc -a --quiet

使用的 go 版本是go1.14.1 darwin/amd64

package main

import "os/exec"
import "fmt"

func main() {
    cmdStr := "docker ps"
    fmt.Printf("cmdStr is %s", cmdStr)
    out, _ := exec.Command("/bin/sh", "-c", cmdStr).Output()
    fmt.Printf("output is %s", out)
}

我在我的 Mac 上得到的上述代码的输出是

cmdStr is docker ps
output is CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

在 pod 的日志中，openshift 3.11 上的相同是：

cmdStr is docker ps
output is

另一种选择是使用此链接中的代码：https ://godoc.org/github.com/google/cadvisor/container/crio#pkg-subdirectories但我不知道如何使用它，一个例子会有所帮助.

go get github.com/google/cadvisor/container/crio
