lablink-client-service 0.0.1

Lablink Client Service that will be installed in the lablink-client-base-image

lablink-client-service

Description

This folder contains the Python Package installed in the VM instance. The service is designed to run on a Ubuntu system with NVIDIA GPU support, specifically for use with Chrome Remote Desktop. This is the client side (VM instance) of the LabLink infrastructure. The subscribe.py will run as a startup script in the VM.

Depdenencies

While the VMs will just install these dependencies globally, developers should use a venv. For developers:

1. Open terminal in project root directory
2. Create a virtual environment

python3 -m venv venv

3. Activate the virtual environment

source venv/bin/activate

4. Install the dependencies

pip install -e ".[dev]"

5. Deactivate the virtual environment when done

deactivate

6. To remove the virtual environment, delete the venv directory

Usage

Run the subscribe.py script to start the service. This script will subscribe to the LabLink server and listen for incoming messages.

python -m lablink_client_service.subscribe

This script will run with the default configuration. To change the configuration, you can modify the config.yaml file in the lablink_client_service directory. The script will automatically load the configuration from this file.

Configuration

The configuration can be overridden by passing a different config file path as an argument to the script. For example:

python -m lablink_client_service.subscribe db.dbname=<db-name> db.host=<db-host> db.port=<db-port> db.user=<db-user> db.password=<db-password> db.table_name=<db-table-name>

• db.dbname: The name of the PostgreSQL database to connect to.
• db.host: The host of the database.
• db.port: The port of the database.
• db.user: The user to connect to the database.
• db.password: The password to connect to the database.
• db.table_name: The name of the table to use in the database.

You can also fix the configuration by modifying the config.yaml file in the lablink_client_service directory. The script will automatically load the configuration from this file.
