I have been working on a web application using the Node JS web framework, Hapi JS. Unfortunately, I am facing some issues with dockerizing my application.
My process began by setting up npm for the project with the command:
npm init
I then proceeded to install hapi js using the command:
@hapi/hapi
Following that, I created the server.js file containing the code snippet below:
'use strict';
const Hapi = require('@hapi/hapi');
const init = async () => {
const server = Hapi.server({
port: 4000,
host: 'localhost'
});
server.route({
method: 'GET',
path: '/',
handler: (request, h) => {
return 'Hello World!';
}
});
await server.start();
console.log('Server running on %s', server.info.uri);
};
process.on('unhandledRejection', (err) => {
console.log(err);
process.exit(1);
});
init();
Upon running node server.js in the terminal and accessing localhost:4000 in the browser, I successfully see the "Hello World!" message.
I then proceeded with dockerizing the application. First, I created a Dockerfile containing the following instructions:
FROM node:14-alpine
RUN apk update && apk upgrade
RUN apk add nodejs
RUN rm -rf /var/cache/apk/*
COPY . /
RUN cd /; npm install
EXPOSE 4000
CMD ["node", "/server.js"]
Furthermore, I created a docker-compose.yaml file with the following configuration:
version: '3.8'
services:
server:
container_name: hapi-web-server
build: .
ports:
- 4000:4000
After executing docker-compose up -d in the terminal and navigating to localhost:4000 in the browser, I encountered an error as shown in this image.
I am seeking guidance on identifying what is wrong with my code and how I can rectify it.
