Basic File Upload and Serving in Go

This repository contains a simple Go application that allows uploading files to a server. The application is containerized using Docker, providing an isolated and reproducible environment.

Getting Started

Follow the steps below to build and run the Go application using Docker:

1. Clone the repository:

   git clone git@github.com:VincentSchmid/file-server.git
   cd file-server

2. Build the Docker image:

   docker build -t file-server .

3. Generate an api-key:

   API_KEY=$(openssl rand -base64 32)

4. Run the Docker container:

   docker run -p 8080:8080 -e API_KEY=$API_KEY -v $(pwd)/uploads:/app/uploads file-server

   This command runs a Docker container from the file-server image. It exposes port 8080 on the host machine and maps it to port 8080 inside the container.

   The -v option mounts the uploads directory on the host machine to the /app/uploads directory inside the container. This allows uploaded files to be stored on the host machine.

5. Access the application:

   Open your web browser and visit http://localhost:8080/files to access the upload page. You can use tools like cURL or web browsers to upload files to the server.

Upload and File access

files can be uploaded using the api key header:

curl -X POST -H "X-API-Key: $API_KEY" -F "file=@test.txt" http://localhost:8080/upload

and the files can be accessed browsed:
http://localhost:8080/files

and downloaded using:
http://localhost:8080/files/test.txt

Additional Notes

• .env: (Optional) Environment file to store the API key. Not required if passing the API key as an environment variable directly.
• Uploaded files will be stored in the uploads directory on the host machine due to the volume mount configuration -v $(pwd)/uploads:/app/uploads. Adjust the path as needed.
