在Docker容器中运行命令'node filename.js'

Question

I need to run a file js inside a Docker container every day at midnight. 我需要每天午夜在Docker容器中运行一个文件js。

Here's my file midnight.sh 这是我的文件midnight.sh

#!/bin/bash

docker exec -it hash_app bash

node midnight.js

Docker exec works fine. Docker exec工作正常。 But the command 'node midnight.js' doesn't work. 但是命令“ node midnight.js”无效。

How can I execute midnight.js inside a docker container? 如何在docker容器中执行midnight.js？

Answer 1

Use -c to send commands as string : 使用-c以字符串形式发送命令：

docker exec -it hash_app bash -c "node midnight.js"

Assuming your file is located in /midnight.js otherwise : 假设您的文件位于/midnight.js否则：

docker exec -it hash_app bash -c "cd /path/to/dir;node midnight.js"

在Docker容器中运行命令&#39;node filename.js&#39;
