Issue
I am trying to deploy my Spring boot and react-based application on an Amazon EC2 instance. My health status has transitioned to a warning.
My logs of the aws ec2 instance are :

I tried to build docker image with aws database url which was successful but my frontend application is on react can understand why it is not working, why it is not being deployed?
Solution
Let's break down the issues and solve them step by step:
Exec format error:
You have multiple log entries:
exec /usr/local/bin/docker-entrypoint.sh: exec format errorThis error usually indicates that there's a problem with the entry point script (
docker-entrypoint.sh) for your container. The most common causes for this error include:- The entry point script does not have the executable permissions.
- The entry point script has Windows-style line endings (if you developed on Windows) instead of UNIX-style line endings.
To solve this:
- Ensure the script has executable permissions:
chmod +x /path/to/your/docker-entrypoint.sh - If you're developing on Windows, you can convert the line endings using tools like
dos2unixor any text editor that allows you to convert line endings.
Mismatched Ports:
In your
Dockerfilefor the React application, you're exposing port5173:EXPOSE 5173However, in the
Dockerrun.aws.jsonfile, the container port you're trying to map is5137:{ "hostPort": 80, "containerPort": 5137 }This is a mismatch. You need to ensure that both the ports are the same, either
5173or5137, whichever is the correct one.Environment Variable for React Frontend:
Your React frontend likely needs to know the URL of your backend API to make calls to it. In the Docker Compose file, you're passing this information as an argument to the Docker build:
build: args: api_base_url: http://localhost:8088This only works if you're building your Docker image every time you deploy, and that the API URL does not change. If you have a static API URL, it's better to pass it as an environment variable to the running container, similar to how you pass the
SPRING_DATASOURCE_URLto your Spring Boot application.Networking on AWS:
Docker Compose creates a custom network for the services defined in a
docker-compose.ymlfile, allowing them to communicate with each other using the service names as hostnames (e.g.,dbfor the database,fullstack-apifor the API). However,Dockerrun.aws.jsondoesn't create such a network by default.If your React frontend communicates with the Spring Boot backend, ensure they are on the same network, or the React frontend knows the correct URL to communicate with the backend.
DevTools in Production:
The logs indicate that Spring Boot's DevTools is active:
.e.DevToolsPropertyDefaultsPostProcessor : Devtools property defaults active!It's not recommended to have DevTools active in a production environment. Ensure that DevTools is not included in the production build of your application.
Database Connection:
Ensure that the database hosted on RDS is accessible from the EC2 instance where your application is deployed. Security groups, VPC configurations, or the RDS instance's public accessibility setting can affect this.
After addressing these issues, try redeploying your application. If you continue to encounter issues, check the logs for any new or persisting errors.
