AWS provides a free tier to experience its services for free in 1 year. And you can follow the step by step in this tutorial without caring about pricing.
You need to go to Amazon AWS and sign up for AWS free tier first.
And we’re gonna do these steps:
- Install Elastic Beanstalk CLI (EB CLI)
- Initialize Beanstalk for Spring Boot application
- Configure environment for MySQL in AWS RDS database
- Deploy and test the application
What is AWS Elastic Beanstalk?
Elastic Beanstalk provides way to quickly deploy and manage Go, Java, .NET, Node.js, PHP, Python, or Ruby applications in the AWS Cloud.
We don’t need to to learn about the infrastructure which runs the applications. Just upload the application, Elastic Beanstalk automatically handles the details of capacity provisioning, load balancing, scaling, and application health monitoring.
When we deploy your application, Elastic Beanstalk builds the selected platform version and provisions one or more AWS resources, such as Amazon EC2 instances, to run your application.
To interact with Elastic Beanstalk, we can use the Elastic Beanstalk console, the AWS Command Line Interface (AWS CLI), or EB CLI.
In this tutorial, we choose Elastic Beanstalk Command Line Interface.
Step 0: Get Spring Boot Application to deploy on AWS
Let’s use a Spring Boot CRUD Restful Apis that works with MySQL database. You can download the source code at Github.
$ git clone https://github.com/bezkoder/spring-boot-data-jpa-mysql.git
This Spring Boot App contains a Rest service as well as MySQL database. That helps you understand how to deploy a Restful Web Service on AWS instead of simple Hello World.
The application exports APIs as following:
|POST||/api/tutorials||create new Tutorial|
|GET||/api/tutorials||retrieve all Tutorials|
|GET||/api/tutorials/:id||retrieve a Tutorial by |
|PUT||/api/tutorials/:id||update a Tutorial by |
|DELETE||/api/tutorials/:id||delete a Tutorial by |
|DELETE||/api/tutorials||delete all Tutorials|
|GET||/api/tutorials/published||find all published Tutorials|
|GET||/api/tutorials?title=[keyword]||find all Tutorials which title contains |
The tutorial showing how to build this app can be found at:
Spring Boot, Spring Data JPA – Building Rest CRUD API example
Step 1: Install EB CLI (Elastic Beanstalk Command Line Interface)
The AWS Elastic Beanstalk Command Line Interface is a command line client provides ways to create, configure, manage, monitor Elastic Beanstalk environments.
The EB CLI requires Python version 2.7, 3.4, or later that you can download at https://www.python.org/downloads/.
Run the following command:
$ pip install awsebcli --upgrade
--upgrade: to upgrade any requirements that are already installed.
Step 2: Initialize Beanstalk project for Spring Boot application
To initialize an EB CLI project, open command prompt at Spring Boot App root folder, then run the command
Select a default region 1) us-east-1 : US East (N. Virginia) 2) us-west-1 : US West (N. California) 3) us-west-2 : US West (Oregon) 4) eu-west-1 : EU (Ireland) 5) eu-central-1 : EU (Frankfurt) 6) ap-south-1 : Asia Pacific (Mumbai) 7) ap-southeast-1 : Asia Pacific (Singapore) 8) ap-southeast-2 : Asia Pacific (Sydney) 9) ap-northeast-1 : Asia Pacific (Tokyo) 10) ap-northeast-2 : Asia Pacific (Seoul) 11) sa-east-1 : South America (Sao Paulo) 12) cn-north-1 : China (Beijing) 13) cn-northwest-1 : China (Ningxia) 14) us-east-2 : US East (Ohio) 15) ca-central-1 : Canada (Central) 16) eu-west-2 : EU (London) 17) eu-west-3 : EU (Paris) 18) eu-north-1 : EU (Stockholm) 19) ap-east-1 : Asia Pacific (Hong Kong) 20) me-south-1 : Middle East (Bahrain) (default is 3):
You can choose any region above, or just enter for default:
Then use your AWS Access Id and AWS Secret Key. If you don’t know where they are, just go to Identity and Access Management (IAM).
Just type your name, press Enter button to select the application.
Now we need to choose platform:
Select a platform. 1) Python (BETA) 2) Docker (BETA) 3) Ruby (BETA) 4) Go (BETA) 5) Node.js (BETA) 6) PHP (BETA) 7) Node.js 8) PHP 9) Python 10) Ruby 11) Tomcat 12) IIS 13) Docker 14) Multi-container Docker 15) GlassFish 16) Go 17) Java 18) Corretto (BETA) 19) Packer (default is 1): 17
17 to select Java, then
1 for Java 8.
Then no for CodeCommit, and Yes for SSH to proceed with SSH setup if you need to login to EC2 instances.
We also create an SSH KeyPair:
OK, done! just go to the next step.
Step 3: Configure Deployment for Spring Boot Application
Now Elastic beanstalk will automatically create a configuration file in Spring Boot project directory: .elasticbeanstalk/config.yml.
branch-defaults: master: environment: null group_suffix: null global: application_name: spring-boot-data-jpa-mysql branch: null default_ec2_keyname: bezkoder-app-key default_platform: Java 8 default_region: us-west-2 include_git_submodules: true instance_profile: null platform_name: null platform_version: null profile: eb-cli repository: null sc: git workspace_type: Application
Our application will be built as jar package. So we add configuration for the deployment as below:
deploy: artifact: target/spring-boot-data-jpa-0.0.1-SNAPSHOT.jar
spring-boot-data-jpa is the artifact of our application and
0.0.1-SNAPSHOT is the version.
spring-boot-data-jpa-0.0.1-SNAPSHOT.jar file will be generated in the target folder when we package the Spring Boot application with the command:
$ mvn clean package spring-boot:repackage
Step 4: Configure environment for Spring Boot with MySQL on AWS
Let’s create an Elastic Beanstalk environment with the command:
$ eb create --single --database
Because an elastic beanstalk application could have multiple environments, we use
--single for a single EC2 instance and an RDS database. If not, multiple instances will be created with a load balancer which cost our money.
$ eb create --single --database Enter Environment Name (default is spring-boot-data-jpa-mysql-dev): spring-boot-dev Enter DNS CNAME prefix (default is spring-boot-dev): Would you like to enable Spot Fleet requests for this environment? (y/N): N
Now type username and password for the RDS database:
Enter an RDS DB username (default is "ebroot"): boot Enter an RDS DB master password: Retype password to confirm:
The console shows:
Uploading: [##################################################] 100% Done... Environment details for: spring-boot-dev Application name: spring-boot-data-jpa-mysql Region: us-west-2 Deployed Version: app-cf24-200408_183238 Environment ID: e-tbmssip4un Platform: arn:aws:elasticbeanstalk:us-west-2::platform/Java 8 running on 64bit Amazon Linux/2.10.4 Tier: WebServer-Standard-1.0 CNAME: spring-boot-dev.us-west-2.elasticbeanstalk.com Updated: 2020-04-08 11:33:04.032000+00:00 Printing Status: 2020-04-08 11:33:03 INFO createEnvironment is starting. 2020-04-08 11:33:04 INFO Using elasticbeanstalk-us-west-2-668363982883 as Amazon S3 storage bucket for environment data. 2020-04-08 11:33:25 INFO Created security group named: awseb-e-tbmssip4un-stack-AWSEBSecurityGroup-T3UYE8P9CGUY 2020-04-08 11:33:40 INFO Creating RDS database named: aazuzc8hjztxex.

Let’s open AWS Console with the command:
You can see our Elastic Beanstalk environment:
It can change to Warning or Severe. Don’t worry, we need to set some configuration.
Click Configuration tab on the left side, the database shows the information as following:
By default, Spring Boot applications will listen on port
8080. Elastic Beanstalk assumes that the application will listen on port
5000. So we will change the port the Spring Boot application listens on.
eb setenv for the work:
$ eb setenv SERVER_PORT=5000
eb setenv with endpoint and port in the image above, username and password we’ve set before:
/ebdb SPRING_DATASOURCE_USERNAME= SPRING_DATASOURCE_PASSWORD= SPRING_JPA_HIBERNATE_DDL_AUTO=update SPRING_JPA_DATABASE_PLATFORM=org.hibernate.dialect.MySQL5Dialect
$ eb setenv SPRING_DATASOURCE_URL=jdbc:mysql://aazuzc8hjztxex.cuu9yoekn2fa.us-west-2.rds.amazonaws.com:3306/ebdb SPRING_DATASOURCE_USERNAME=root SPRING_DATASOURCE_PASSWORD=12345678 SPRING_JPA_HIBERNATE_DDL_AUTO=update SPRING_JPA_DATABASE_PLATFORM=org.hibernate.dialect.MySQL5Dialect
The console shows:
2020-04-08 12:03:03 INFO Environment update is starting. 2020-04-08 12:03:11 INFO Updating environment spring-boot-dev's configuration settings. 2020-04-08 12:04:33 INFO Successfully deployed new configuration to environment.
Now open AWS Console, in Configuration tab, click on Edit button in Software Category, we can see all of Environment properties here:
Step 5: Deploy the Spring Boot application to AWS
Now we just run the command for deploying the Spring Boot application to the instances in the Elastic Beanstalk environment.
$ eb deploy Uploading: [##################################################] 100% Done... 2020-04-08 12:16:42 INFO Environment update is starting. 2020-04-08 12:16:46 INFO Deploying new version to instance(s). 2020-04-08 12:17:05 INFO New application version was deployed to running EC2 instances. 2020-04-08 12:17:05 INFO Environment update completed successfully.
Check the AWS Console:
If you want to deploy with a label version, just use:
eb deploy --label [your-version].
If the label has already been used, the EB CLI redeploys the previous version with that label.
eb deploy --label v01 Uploading: [##################################################] 100% Done... 2020-04-08 12:22:42 INFO Environment update is starting. 2020-04-08 12:22:46 INFO Deploying new version to instance(s). 2020-04-08 12:23:04 INFO New application version was deployed to running EC2 instances. 2020-04-08 12:23:04 INFO Environment update completed successfully.
Step 6: Test the application
This is the final section of the tutorial, we’re gonna use Postman to test the Spring Boot Rest Apis which was deployed on AWS.
– Create an object:
– Retrieve all objects:
– Update an object:
– Find objects by field:
Today we’ve done many things for deploying Spring Boot Application on AWS EC2 Instance using Elastic Beanstalk. Now you can:
- Install EB CLI and setup AWS Beanstalk environment
- Create database, configure connection properties and set environment variables
- Build and deploy Spring Boot application on AWS
- Test the application
