Step 1. Create a Simple Node App
First, run the following commands to create and navigate to our application’s directory:
- $ mkdir app
- $ cd app
Next, create an npm project:
npm init --y
Install Express:
npm install express
Create an index.js file with the following code:
const express = require('express')
const app = express()
const port = 3000
app.get('/', (req, res) => res.send('Hello Cloud Engineers from ECS services!'))
app.listen(port, () => console.log(`Example app listening on port ${port}!`))
The app can then run with this command:
$ node index.js You should see your app at http://localhost:3000/:
Build and publish image
1. to login to docker ecr
docker login -u AWS -p $(aws ecr get-login-password --region us-east-1) 216952475463.dkr.ecr.us-east-1.amazonaws.com
2. build your docker image
docker build -t nashwan .
3. After the build completes, tag your image so you can push the image to this repository:
docker tag nashwan:latest 216952475463.dkr.ecr.us-east-1.amazonaws.com/nashwan:latest
4. Run the following command to push this image to your newly created AWS repository:
docker push 216952475463.dkr.ecr.us-east-1.amazonaws.com/nashwan:latest
