英文:

Error while running Docker run docker: Error response from daemon

问题

以下是将在 Docker 容器内运行 Bash 脚本并接受两个输入并在容器内生成文件的 Docker 文件：

```Dockerfile
FROM ubuntu:latest

WORKDIR /app

COPY gencsv.sh /app/gencsv.sh

RUN chmod +x /app/gencsv.sh

CMD ["/bin/bash", "/app/gencsv.sh"]

docker run -dp 9393:9393 -v "$(pwd)/inputFile:/app/inputFile" input 2 8

docker: 容器创建失败的错误响应：OCI runtime create failed: container_linux.go:380: 启动容器进程引发了错误：exec: "2": 在 $PATH 中找不到可执行文件：未知。

Below is the Docker file which will run bash script inside docker container and takes two input and generates file inside container

FROM ubuntu:latest

WORKDIR /app

COPY gencsv.sh /app/gencsv.sh

RUN chmod +x /app/gencsv.sh

CMD ["/bin/bash", "/app/gencsv.sh"]`

docker run -dp 9393:9393 -v "$(pwd)/inputFile:/app/inputFile" input 2 8

> docker: Error response from daemon: OCI runtime create failed:
> container_linux.go:380: starting container process caused: exec: "2":
> executable file not found in $PATH: unknown.

# 答案1
**得分**: 1

`exec: "2": executable file not found in $PATH: unknown.` 这个错误意味着你尝试执行"2"作为命令，但（当然）它不是有效的命令，也不在$PATH中。

按照@Tuning85的建议使用Entrypoint。

CMD - 你可以覆盖默认命令。Docker认为你正在尝试执行`2 8`

Entrypoint - 无法被覆盖，命令行参数将作为参数传递给"app/gencsv.sh"脚本。

`exec: &quot;2&quot;: executable file not found in $PATH: unknown.` This error means you&#39;re trying to execute &quot;2&quot; as a command, but (of course) it&#39;s not valid and not in $PATH.

Use Entrypoint as @Tuning85 said.

CMD - you can override the default command. Which docker thinks you are trying to do with `2 8`
Entrypoint - can&#39;t be overridden and the the command line parameters are passed as arguments to &quot;app/gencsv.sh&quot; script
