Thumbnail API

This project retrieves images from our object storage provider(s). No API key is required.

Requirements

The application needs Java17 and Maven v3.8.x or above

Functionality

• We use 2 storages : Amazon S3 and IBM Cloud storage.
• When a request for a thumbnail comes in, the API’s ThumbnailController will always check IBM Cloud storage first and if a thumbnail is not found there it will go on to check if it’s in the old Amazon S3 storage.

Build

mvn clean install (add -DskipTests) to skip the unit tests during build

Deployment

1. Generate a Docker image using the project's Dockerfile

2. Configure the application by generating a thumbnail.user.properties file and placing this in the k8s folder. After deployment this file will override the settings specified in the thumbnail.properties file located in the src/main/resources folder. The .gitignore file makes sure the .user.properties file is never committed.

3. Configure the deployment by setting the proper environment variables specified in the configuration template files in the k8s folder

4. Deploy to Kubernetes infrastructure
