NetAlertX/docs/DEV_ENV_SETUP.md

Development environment set up

Note

Replace /development with the path where your code files will be stored. The default container name is netalertx so there might be a conflict with your running containers.

1. Download the code:

• mkdir /development
• cd /development && git clone https://github.com/jokob-sk/NetAlertX.git

2. Create a DEV .env_dev file

touch /development/.env_dev && sudo nano /development/.env_dev

The file content should be following, with your custom values.

#--------------------------------
#NETALERTX
#--------------------------------
TZ=Europe/Berlin
PORT=22222    # make sure this port is unique on your whole network
DEV_LOCATION=/development/NetAlertX
APP_DATA_LOCATION=/volume/docker_appdata
# ALWAYS_FRESH_INSTALL=true # uncommenting this will always delete the content of /config and /db dirs on boot to simulate a fresh install

3. Create /db and /config dirs

Create a folder netalertx in the APP_DATA_LOCATION (in this example in /volume/docker_appdata) with 2 subfolders db and config.

• mkdir /volume/docker_appdata/netalertx
• mkdir /volume/docker_appdata/netalertx/db
• mkdir /volume/docker_appdata/netalertx/config

4. Run the container

• cd /development/NetAlertX && sudo docker-compose --env-file ../.env_dev

You can then modify the python script without restarting/rebuilding the container every time. Additionally, you can trigger a plugin run via the UI:

💡 Tips

A quick cheat sheet of useful commands.

Removing the container and image

A command to stop, remove the container and the image (replace netalertx and netalertx-netalertx with the appropriate values)

• sudo docker container stop netalertx ; sudo docker container rm netalertx ; sudo docker image rm netalertx-netalertx

Restart the server backend

Most code changes can be tetsed without rebuilding the container. When working on the python server backend, you only need to restart the server.

1. You can usually restart the backend via Maintenance > Logs > Restart server

2. If above doesn't work, SSH into the container and kill & restart the main script loop

• sudo docker exec -it netalertx /bin/bash
• pkill -f "python /app/server" && python /app/server &

3. If none of the above work, restart the docker image. This is usually the last resort as sometimes the Docker engine becomes unresponsive and the whole engine needs to be restarted.
