## Features
- HTTP lightweight server responding with information on your client:
- Client IP (public or private)
- Browser and version
- Device type
- OS and version
- Compatible with amd64, 386, armv6, armv7 and arm64 v8 cpu architectures
## Setup
1. To test port 1234, use:
```bash
docker run -it --rm -p 1234:8000/tcp qmcgaw/port-checker
```
To test port 1234 internally, use:
```bash
docker run -it --rm -e LISTENING_PORT=1234 qmcgaw/port-checker
```
1. With a client, access [http://localhost:1234](http://localhost:1234).
You can also port forward with your router to test it is accessible remotely.
### Binary
You can also download one of the binaries on the Github releases. For example:
```sh
wget -qO port-checker https://github.com/qdm12/port-checker/releases/download/v0.1.0/port-checker_0.1.0_linux_amd64
chmod +x port-checker
./port-checker
# Usage with
./port-checker -help
```
## Environment variables
| Environment variable | Default | Possible values | Description |
| --- | --- | --- | --- |
| `LISTENING_PORT` | `8000` | `1025` to `65535` | TCP port to listen on internally |
| `ROOT_URL` | `/` | URL path string | Used if it is running behind a proxy for example |
## Development
### Using VSCode and Docker
1. Install [Docker](https://docs.docker.com/install/)
- On Windows, share a drive with Docker Desktop and have the project on that partition
1. With [Visual Studio Code](https://code.visualstudio.com/download), install the [remote containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)
1. In Visual Studio Code, press on `F1` and select `Remote-Containers: Open Folder in Container...`
1. Your dev environment is ready to go!... and it's running in a container :+1:
