TPXLE Network Interface Translator for Helium and TTN

Build and install the server

Make sure that beyond docker engine you have docker-compose available on your platform.

Clone this repo and enter to the folder of this project

$ git clone https://github.com/actility/tpxle-nit
$ cd tpxle-nit

For customised config set the environment variables in the docker-compose.yml file.
Build the docker images:

Execute the following command from the project root where the docker-compose.yml file is located
```
$ docker-compose build
```
Create containers without starting them:
```
$ docker-compose up --no-start
```
Run containers in detached mode
```
$ docker-compose up --detach
```
For a production platform I recommend to configure an nginx reverse proxy so that http://localhost:<PORT_NUMBER> is mapped to a public https://<PUBLIC_DOMAIN_NAME>/<APP_NAME> web page with proper certifications. For that the following text need to be added to the nginx server configuration:
```
location /<APP_NAME>/ {
    proxy_pass http://localhost:<PORT_NUMBER>/;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
}
```

Connect to the tpxle_nit_app container via CLI:

$ docker container exec -it tpxle_nit_app /bin/sh

Check if the server is running:
```
/opt/tpxle-nit/src # ps -ef
```
If the server is not running start the app manually:
```
/opt/tpxle-nit/src # npm start &
```

You can check the logs with:

/opt/tpxle-nit/src # tail -f ./log/current.log

Check if the server works here: http://localhost:8081/test
