Contrary to EC2, Elastic Beanstalk has Node.js, Go, Java, PHP … installed out of the box 😻. That lets you deploy, monitor and scale your application without having to worry about the infrastructure setup. In this post I will show you how to deploy a simple Node.js application on Elastic Beanstalk.
1 – Elastic Beanstalk setup with AWS Console
Go to AWS Management Console, then click on “Elastic Beanstalk”:
Next, click on “Create New Application”:
Assign a name and a short description for your application, then click on “Create”:
Next, create a new environment by clicking on “Create one now”:
Choose “Web server environment”:
Then fill the form as below:
It will take anywhere from 2 – 5 minutes for Elastic Beanstalk to fully create the necessary instances and start the web app.
After a couple minutes, you should see:
If you point your browser to the URL shown above:
Congratulations 😁 you have successfuly deployed a simple Node.js app on EB.
2 – Upload your App Code
Note: You can use your own code if your Node.js application is ready to be deployed.
Download the simple Node.js app from my Github.
Then, on the EB Dashboard click on “Upload and Deploy“:
A popup will show up, so upload your app code and assign a version to it, then click on “Deploy“:
Once the Application has been upgraded you can jump directly to it’s webpage by clicking on the URL shown on the dashboard.
3 – Elastic Beanstalk setup with EB CLI
In this section, I will show you how to deploy the same app by using the AWS EB CLI.
First, install the CLI, if you already have pip you can issue the following command:
pip install --upgrade --user awsebcli
After you install the EB CLI, add the path to the executable file to your PATH variable.
Once done, you need to create a new user account in order to manage EB resources with EB CLI. I already did a tutorial on how to create a new User with IAM, so I won’t repeat it. There is one way you’ll want to differ from the tutorial:
- Add AWSElasticBeanstalkFullAccess to the user permissions list:
Copy down the Access Key ID and Secret Access Key. We’ll need this to connect via the EB CLI interface.
Then, modify your ~/.aws/credentials file and add the following content:
Then in your Node.js application directory, configure EB by typing the following command:
The command take as arguments:
- –profile : the user profile we created earlier
- -p: the application language
then set the region on which you want to deploy your application.
Once you finish , issue the command ‘eb-create‘:
After the EB instance is created you can deploy it:
Once deployed , you can open the app by either clicking on the URL on the EB Dashboard:
or by running the command ‘eb open‘:
4 – EB CLI commands
4.1 – eb logs
To pull logs from the instance:
4.2 – eb health
To check the health status of the app:
4.3 – eb terminate –all
To clean up the EB instance:
