Docker Deployment
This guide explains how to deploy the Image Resize Service using Docker.
Prerequisites
- Docker installed
Building the Docker Image
A Dockerfile is provided in the project root.
# Navigate to the project root
cd /path/to/image-resizer
# Build the Docker image
docker build -t image-resizer:latest .
Running the Docker Container
Basic Run
This will run the service in detached mode and map port 8080 of the container to port 8080 on the host.
With Environment Variables
You can configure the service using environment variables. See the Configuration guide for available variables.
docker run -d -p 8080:8080 \
-e PORT=8080 \
-e STORAGE_TYPE=s3 \
-e S3_BUCKET=my-image-bucket \
-e AWS_ACCESS_KEY_ID=YOUR_ACCESS_KEY \
-e AWS_SECRET_ACCESS_KEY=YOUR_SECRET_KEY \
-e S3_REGION=us-east-1 \
--name image-resizer-app \
image-resizer:latest
Using Docker Compose
A compose.yaml file is provided for easier local development and deployment.
# Start the service
docker-compose up -d
# Stop the service
docker-compose down
# View logs
docker-compose logs -f
The compose.yaml file typically includes: - The application service definition. - Potentially other services like a local MinIO instance for S3 testing.
Refer to the compose.yaml in the project root for the exact configuration.
Managing the Container
- View logs:
docker logs image-resizer-app - Stop the container:
docker stop image-resizer-app - Start the container:
docker start image-resizer-app - Remove the container:
docker rm image-resizer-app
Pushing to a Docker Registry
If you want to deploy the image to a remote environment (like Kubernetes), you'll need to push it to a Docker registry (e.g., Docker Hub, AWS ECR, Google GCR).
```bash
Tag the image (replace and )
docker tag image-resizer:latest
Log in to your Docker registry
docker login
Push the image
docker push
