AWS Elastic Beanstalk (EB) is a powerful service that allows developers to deploy, manage, and scale applications in the AWS cloud without the need to understand the underlying infrastructure. The EB Command Line Interface (EB CLI) is a tool that provides a direct method to interact with Elastic Beanstalk, making the deployment process even smoother. In this guide, we'll walk you through the steps to deploy an application on AWS Elastic Beanstalk using the EB CLI.
Setting the Stage: EB CLI Installation
Before diving into the deployment process, ensure that the EB CLI is installed on your system. If you haven't done this yet, follow our comprehensive guide on how to set up the EB CLI.
Step 1: Verifying the EB CLI Version
To ensure you're working with the latest version of the EB CLI, run the following command:
eb --versionStep 2: Preparing Your Application for Deployment
For demonstration purposes, we'll deploy a basic index.html file. Create this file and add your desired content:
<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My Elastic Beanstalk App</title>
</head>
<body>
<h1>Welcome to My Elastic Beanstalk Application!</h1>
<p>This is a simple demonstration of deploying an app using EB CLI.</p>
</body>
</html>Step 3: Initializing the EB Environment
Begin by initializing your EB environment:
eb initYou'll be prompted to select a region for deployment. For this example, we'll choose the Mumbai region (option 6). Next, provide a name for your application and select the desired runtime. If you wish to set up SSH for your instance, enter 'yes' when prompted.
Step 4: Creating the EB Environment
With the initial setup complete, create the EB environment:
eb createFollow the on-screen instructions, specifying the environment name and DNS. For the load balancer type, we recommend sticking with the default "application" option.
Step 5: Monitoring Your Deployment
Once the deployment process begins, you can monitor its progress directly from the AWS Management Console. Navigate to Elastic Beanstalk and refresh the page to view the status of your environment.
To view your deployed application, use the provided URL. Additionally, the EB CLI offers various commands to manage and monitor your environment:
- View logs:
eb logs - Check health:
eb health - View events:
eb events - Open application in a browser:
eb open - Terminate the environment:
eb terminate
Remember, terminating the environment will delete most associated resources. However, you'll need to manually delete the S3 bucket used during deployment.
Conclusion
Deploying applications on AWS Elastic Beanstalk using the EB CLI is a streamlined process that offers developers greater control and flexibility. By mastering these steps, you can efficiently manage and scale your applications in the AWS cloud.
HAPPY DEPLOYING!
