How can I solve this error?我该如何解决这个错误?
I assume you're either incorrectly specifying your script in the package.json
or your script is not server.js
.我假设您在
package.json
中错误地指定了您的脚本,或者您的脚本不是server.js
。
A minimal repro of your question works:您的问题的最小复制工作:
Using the Node.JS Getting Started guide's example with one minor tweak: https://nodejs.org/en/docs/guides/getting-started-guide/使用 Node.JS 入门指南的示例并稍作调整: https://nodejs.org/en/docs/guides/getting-started-guide/
NOTE Change
const hostname = '127.0.0.1';
注意更改
const hostname = '127.0.0.1';
toconst hostname = '0.0.0.0';
到
const hostname = '0.0.0.0';
This is necessary to access the containerized app from the host.这是从主机访问容器化应用程序所必需的。
Adding a package.json because you have one and to show npm start
:添加 package.json 因为您有一个并显示
npm start
:
package.json
: package.json
:
{
"name": "66281738",
"version": "0.0.1",
"scripts": {
"start": "node app.js"
}
}
NOTE I believe
npm start
defaults to"start": "node server.js"
注意我相信
npm start
默认为"start": "node server.js"
Using your Dockerfile
and:使用您的
Dockerfile
和:
QUESTION="66281738"
docker build --tag=${QUESTION} --file=./Dockerfile .
docker run --interactive --tty --publish=7777:3000 ${QUESTION}
Yields:产量:
> 66281738@0.0.1 start
> node app.js
Server running at http://0.0.0.0:3000/
NOTE
docker run
binds the container's:3000
port to the host's:7777
just to show these need not be the same.注意
docker run
将容器的:3000
端口绑定到主机的:7777
只是为了表明它们不必相同。
Then:然后:
curl --request GET http://localhost:3000/
Yields:产量:
