In this article we will explore a simple way to deploy springboot 3 based microservice to AWS EC2 Instance.
If you don’t have an account already in AWS or haven’t created any instance yet then follow steps mentioned here
Steps in this tutorial
- Create microservice using springboot 3
- Connect to EC2 instance via SSH.
- Install Java, Git & maven on EC2 instance
- Clone application git repo
- Start application using maven
- Test Application URL
- Stop/Terminate instance
1. Create microservice using springboot 3
For this article we are going to use the userbook service which is already created using springboot 3 and explained in this article.
2. Connect to EC2 instance via SSH
Run below command to connect EC2 instance
ssh -i <key-pair>.pem ec2-user@<Public IPv4 DNS of EC2>
Replace these fields in above command
<key-pair>.pem — File name of key-pair file generate from AWS while creating EC2.
<Public IPv4 DNS of EC2> — Can be obtained from EC2 instance summary Networking tab.
3. Install Java, Git & maven on EC2 instance
Run these commands in EC2 instance via ssh session.
- Install Java using command
sudo yum install java-17-amazon-corretto.x86_64
2. Install Git using command
sudo yum install git-core.x86_64
3. Install Maven using command
sudo yum install maven.noarch
4. Clone application git repo
Run command to clone userbook application repo from github
git clone https://github.com/hk-springboot-projects/userbook.git
5. Start application using maven
Run below commands to start application
cd userbook
mvn spring-boot:run
Application will be started at port 8080.
6. Test Application URL
Open any browser and type below url
http://<Public IPv4 DNS of EC2>:8080/users
you should see a list of users in response. userbook application uses embedded H2 database and default list of users are initialized on application bootstrap.
Play around with other APIs (POST/PUT/DELETE) using postman or any other api testing tool of your choice.
7. Stop/Terminate instance
Don’t forget to Stop or Terminate your instance once you are done with above steps.
Happy Learning.
