Explanation

Create a Spring Boot executable JAR file using Maven before deploying the application to EC2.

Code:

mvn clean package

Explanation

The generated JAR file is usually available inside the target directory.

Code:

target/
  └── employee-service-0.0.1-SNAPSHOT.jar

Explanation

Install Java on the EC2 Linux server and verify the installed version.

Code:

sudo apt update
sudo apt install openjdk-17-jdk -y
java -version

Explanation

Copy the Spring Boot JAR file from the local machine to the EC2 server using SCP or another secure transfer method.

Code:

scp -i aws-key.pem \
 target/employee-service.jar \
 ubuntu@EC2_PUBLIC_IP:/home/ubuntu/

Explanation

Run the Spring Boot application on EC2 and allow the required port through the security group.

Code:

java -jar employee-service.jar

Application URL:
http://EC2_PUBLIC_IP:8080
