下载了较新的映像 - docker：来自守护进程的错误响应：OCI 运行时创建失败：container_linux.go:348：

Question

我想下载busybox图像并得到它，但尽管如此，我还是有以下错误：

? bgarcial [~] ? sudo docker run busybox:1.29 "hello world"
Unable to find image 'busybox:1.29' locally

使用其他图像不会发生相同的错误，例如命令sudo docker run mongo:4-xenial...

我的问题可能是当我将“hello world”作为参数传递到我的容器中时吗？

当您将命令传递给 Docker 容器时，它必须可以从 Docker 容器内的 shell 执行。在这种情况下，“Hello World”被视为您尝试运行的可执行文件的名称。由于这不是有效的可执行文件名称，Docker 返回以下错误。

[root@testvm1 test]# docker run busybox "Hello World"
container_linux.go:247: starting container process caused "exec: \"Hello World\": executable file not found in $PATH"
/usr/bin/docker-current: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"Hello World\": executable file not found in $PATH".

请注意这一行："exec: \"Hello World\": executable file not found in $PATH"。

使用在容器内有效的命令，例如echo要使其工作：

[root@testvm1 test]# docker run busybox echo "Hello World"
Hello World

请注意，如果您使用 shell 以交互方式运行容器，您将看到相同的行为：

[root@testvm1 test]# docker run -it busybox /bin/sh
/ # "Hello World"
/bin/sh: Hello World: not found
/ # echo "Hello World"
Hello World
