# static-file-server

## Introduction
Tiny, simple static file server using environment variables for configuration.
Install from any of the following locations:

- Docker Hub: https://hub.docker.com/r/halverneus/static-file-server/
- GitHub: https://github.com/halverneus/static-file-server

## Configuration

### Environment Variables

Default values are shown with the associated environment variable.

```bash
# Enable debugging for troubleshooting. If set to 'true' this prints extra
# information during execution.
DEBUG=false
# Optional Hostname for binding. Leave black to accept any incoming HTTP request
# on the prescribed port.
HOST=
# If assigned, must be a valid port number.
PORT=8080
# Automatically serve the index file for a given directory (default). If set to
# 'false', URLs ending with a '/' will return 'NOT FOUND'.
SHOW_LISTING=true
# Folder with the content to serve.
FOLDER=/web
# URL path prefix. If 'my.file' is in the root of $FOLDER and $URL_PREFIX is
# '/my/place' then file is retrieved with 'http://$HOST:$PORT/my/place/my.file'.
URL_PREFIX=
# Paths to the TLS certificate and key. If one is set then both must be set. If
# both set then files are served using HTTPS. If neither are set then files are
# served using HTTP.
TLS_CERT=
TLS_KEY=
```

### YAML Configuration File

YAML settings are individually overridden by the corresponding environment
variable. The following is an example configuration file with defaults. Pass in
the path to the configuration file using the command line option
('-c', '-config', '--config').

```yaml
debug: false
host: ""
port: 8080
show-listing: true
folder: /web
url-prefix: ""
tls-cert: ""
tls-key: ""
```

## Deployment

### Without Docker

```bash
PORT=8888 FOLDER=. ./serve
```

Files can then be accessed by going to http://localhost:8888/my/file.txt

### With Docker

```bash
docker run -d \
    -v /my/folder:/web \
    -p 8080:8080 \
    halverneus/static-file-server:latest
```

This will serve the folder "/my/folder" over http://localhost:8080/my/file.txt

Any of the variables can also be modified:

```bash
docker run -d \
    -v /home/me/dev/source:/content/html \
    -v /home/me/dev/files:/content/more/files \
    -e FOLDER=/content \
    -p 8080:8080 \
    halverneus/static-file-server:latest
```

### Getting Help

```bash
./serve help
# OR
docker run -it halverneus/static-file-server:latest help
```
