# SessionZero Docker Deployment Guide

This guide explains how to build and deploy the SessionZero Blazor WebAssembly PWA using Docker.

## Prerequisites

- Docker installed on your machine
- Docker Compose installed on your machine (optional, but recommended)

## Building and Running with Docker Compose (Recommended)

1. Navigate to the project root directory (where the `docker-compose.yml` file is located)
2. Run the following command to build and start the container:

   ```bash
   docker-compose up -d --build
   ```

3. Access the application at http://localhost:80

## Building and Running with Docker CLI

1. Navigate to the project root directory (where the `Dockerfile` is located)
2. Build the Docker image:

   ```bash
   docker build -t sessionzero .
   ```

3. Run the container:

   ```bash
   docker run -d -p 80:80 --name sessionzero-app sessionzero
   ```

4. Access the application at http://localhost:80

## Stopping the Container

### With Docker Compose

```bash
docker-compose down
```

### With Docker CLI

```bash
docker stop sessionzero-app
docker rm sessionzero-app
```

## Troubleshooting

- If you encounter any issues with the container not starting, check the logs:

  ```bash
  docker logs sessionzero-app
  ```

- Make sure port 80 is not being used by another application on your host machine. Note that port 80 often requires administrative privileges on most operating systems since it's a privileged port.

- If the application doesn't work as expected, verify that all files were copied correctly by inspecting the container:

  ```bash
  docker exec -it sessionzero-app sh
  ls -la /usr/share/nginx/html
  ```
