Pre-requisites:
This section of the workshop assumes you have docker installed. Follow the instructions at https://docs.docker.com/get-docker/ .
Create a new directory “apprunner-example”, and in this directly, create the following files:
index.js
const express = require('express');
const app = express();
const port = 3000;
app.get('/', (req, res) => {
res.send('Hello World!');
});
app.listen(port, () => {
console.log(`Example app listening at http://localhost:${port}`);
});
package.json
{
"name": "apprunner_example",
"version": "1.0.0",
"description": "",
"main": "index.js",
"dependencies": {
"express": "^4.17.1"
},
"devDependencies": {},
"author": "",
"license": "ISC"
}
Dockerfile
FROM node:14
# Create app directory
WORKDIR /usr/src/app
# Install app dependencies
COPY package*.json ./
RUN npm install
# Bundle app source
COPY . .
EXPOSE 3000
CMD [ "node", "index.js" ]
You should now have the following files in your directory:
iamtim@mypc:~/apprunner-example$ ls
Dockerfile index.js package.json
