  • Be able to observe the logs of vantage6 node

Vantage6 node is the software that runs on a data station. It allows the data owner to share their data within the vantage6 network in a privacy enhancing way. Also, it is responsible for the execution of the federated learning tasks and the communication with the vantage6 server.

Each organization that is involved in a federated learning collaboration has its own node in that collaboration. They should therefore install the node software on a (virtual) machine hosted in their own infrastructure. The machine should have access to the data that is used in the federated learning collaboration.

This chapter will explain how to set up and run the vantage6 node software.

Requirements on hardware and software


Hardware requirements

The minimal hardware requirements are:

  • x86 CPU architecture + virtualization enabled. This setting is usually the default in most of the systems.
  • 1 GB memory
  • Sufficient storage to install Python, docker and vantage6, and to store the required docker images (50GB+ recommended).
  • Stable and fast internet connection (1 Mbps+).

The hardware requirements of vantage6 node also depend on the algorithms that the node will run. For example, you need much less compute power for a descriptive statistical algorithm than for a machine learning model.

Even though a vantage6 node can be installed and run on Linux, Windows and Mac, Linux is the recommended OS.

In this lesson, you will use your laptop, but in a production scenario, we recommend to use a server or virtual machine to run the node.

Software requirements

The following software must be installed before installing the vantage6 node:

  • Recommended operating system: Ubuntu 20.04+ , MacOS Big Sur+, or Windows 10+
  • Docker Desktop (Windows, MacOS) or the Docker Engine (Linux)
  • Miniconda (latest version)
  • Python v3.10
  • Python packages:

You should already have installed the requirements before coming to this lesson. They are detailed in the Setup section.

⚠️ Docker installation

  • For Linux users, some post-installation steps may be required (as also mentioned in the setup section). Vantage6 needs to be able to run docker without sudo, and these steps ensure just that.

  • For Windows users, if you are using Docker Desktop, it may be preferable to limit the amount of memory Docker can use - in some cases it may otherwise consume much memory and slow down the system. This may be achieved as described here.

Installation


The Python package vantage6 provides a command-line interface (CLI) to manage the vantage6 infrastructure.

To install this CLI package, run the following command in your Python environment, provided you had not done so already in the Setup section:

BASH

# First go to your python virtual environment
conda create -n v6-workshop python=3.10
conda activate v6-workshop

# Then install the package
pip install vantage6 jupyterlab

To verify the installed CLI, run the command,

BASH

v6 --help

If the installation is successful, it will print out a message explaining the CLI usage.

v6 node commands


The vantage6 CLI provides the v6 node command to manage the vantage6 node instances.

To see how to use it, run the command v6 node --help in your terminal, and it will print out the following messages:

BASH

Usage: v6 node [OPTIONS] COMMAND [ARGS]...

  Manage your vantage6 node instances.

Options:
  --help  Show this message and exit.

Commands:
  attach              Show the node logs in the current console.
  clean               Erase temporary Docker volumes.
  create-private-key  Create and upload a new private key
  files               Prints the location of important node files.
  list                Lists all node configurations.
  new                 Create a new node configuration.
  remove              Delete a node permanently.
  set-api-key         Put a new API key into the node configuration file
  start               Start the node.
  stop                Stop one or all running nodes.
  version             Returns current version of a vantage6 node.

For example, to view the list of available nodes, you can run the command v6 node list.

View the list of nodes

You can use the v6 node list command to see the list of nodes:

BASH

v6 node list

If it print out a long error message, it means the Docker engine is not running:

BASH

Cannot reach the Docker engine! Please make sure Docker is running.
Error while fetching server API version: 502 Server Error for http+docker://localhost/version: Bad Gateway
Traceback (most recent call last):
...

⚠️ Please make sure Docker is running when you’re using the v6 node commands.

Start Docker engine

  • For Windows and MacOS, open Docker Desktop to start the Docker engine.
  • For Linux, Docker engine usually starts automatically when you login. Otherwise, use the commmand sudo systemctl start docker to start the Docker engine.

If the Docker engine is running, you will see the following message:

BASH

Name                     Status          System/User
-----------------------------------------------------
-----------------------------------------------------

You don’t see any nodes in the list because you haven’t created any nodes yet. Next, we will create a new node configuration.

Configure a new node


We will now create a new node configuration using the v6 node new command for the collaboration we created in Chapter 4. This process will create a configuration yaml file that the vantage6 node requires to run.

Prepare the API key and data

Make sure you have the API key downloaded from the vantage6 UI in Episode 4. If you haven’t done so or lost the API key, you can reset the API key for the node in the vantage6 UI, check the Reset API key for a node via the vantage6 UI section.

Go back to the terminal and go to a directory you want to work in:

BASH

cd  path/to/your/directory

Open the jupyter lab in the terminal:

BASH

jupyter lab

In the Jupyter Lab, create a new csv data file data_node1.csv with the following content:

age
1
1
1

Let’s run the command:

BASH

v6 node new

The command will show a wizard to guide you through the configuration process in a step-by-step manner:

BASH

? Please enter a configuration-name: node1
? Enter given api-key: ***
? The base-URL of the server: https://server.workshop.vantage6.ai
? Enter port to which the server listens: 443
? Path of the api: /api
? Task directory path: ***/vantage6/node/node1
? Do you want to add a database? Yes
? Enter unique label for the database: default
? Database URI: ***/data_node1.csv
? Database type: csv
? Do you want to add a database? No
? Do you want to connect to a VPN server? No
? Do you want to add limit the algorithms allowed to run on your node? This should always be done for production scenarios. No
? Which level of logging would you like? DEBUG
? Encryption is disabled for this collaboration. Accept? Yes

It is important to note the meaning of following configuration parameters:

  • The api-key is the API key that you downloaded from vantage6 UI in Chapter 4. It is used to authenticate the node at the server.
  • The base-URL of the server is the URL of the vantage6 server. If you are running the server on your local machine using Docker, the URL has to be set to http://localhost
  • The port to which the server listens is the port number of the server. Check with the server administrator to get the correct port number.
  • The path of the api is the path of the API of the server. By default it is /api.
  • The database URI is the path of the database file containing the sensitive data. You can add multiple databases by repeating the process. The database type can be ‘csv’, ‘parquet’, ‘sql’, ‘sparql’, ‘excel’ or ‘omop’.
  • The unique label for the database is the name of the database. It must be unique. It’s used when you want to refer to the database in the algorithms.
  • The VPN server is used to connect the node to a VPN server. A VPN connection allows nodes to communicate directly with one another, which is useful when some algorithms require direct or a lot of communication between nodes. For more information, see the vantage6 documentation.

To see all configuration options, please check https://docs.vantage6.ai/en/main/node/configure.html#all-configuration-options.

When you finish the configuration, you will see the following message:

BASH

[info ] - New configuration created: ***/vantage6/node/node1.yaml
[info ] - You can start the node by running v6 node start

It means that the node configuration file is created successfully, and it also gives the path of the configuration file.

Where is the node configuration file?

You can always use the v6 node files command to check the location of the node configuration file:

BASH

v6 node files

It will ask you which node you want to see. You can choose the one you just created:

BASH

? Select the configuration you want to use: (Use arrow keys)
 » node1

In the printed message, you will see not only the path of the configuration file is printed out, but also the locations of the log file, the data folders and the database files are shown.

Challenge 1: Create a new node configuration

  1. Create a new node configuration node2 using the v6 node new command for another organization in the collaboration you created in Episode 4:
    • add a new database in the format of csv with only one column named age, you need to make up the data.
  2. Find the path to the configuration file using the v6 node files command. Open the configuration file with a text editor and check the configuration options. Are they correct?
  3. Open your configuration file, do the following:
    • add another database in the format of excel with only one column named age, you need to make up the data.

Start a node


Before starting a vantage6 node, you need to make sure the vantage6 server and Docker are running.

To start a node, you can run the command v6 node start:

BASH

v6 node start

It will ask you which node you want to start. You can choose the one you just created:

BASH

[info ] - Starting node...
[info ] - Finding Docker daemon
? Select the configuration you want to use: (Use arrow keys)
 » node1
   node2

then it will start the node and print out the following messages:

BASH

? Select the configuration you want to use: node1
[info ] - Starting node...
[info ] - Finding Docker daemon
[info ] - Checking that data and log dirs exist
[info ] - Connecting to server at 'https://server.workshop.vantage6.ai:443/api'
[info ] - Pulling latest node image 'harbor2.vantage6.ai/infrastructure/node:4.7'
[info ] - Creating file & folder mounts
[warn ] - private key file provided ***/vantage6/node/node1/private_key.pem, but does not exists
[info ] - Setting up databases
[info ] -   Processing csv database default:***/data_node1.csv
[debug] -   - file-based database added
[info ] - Running Docker container
[info ] - Node container was started!
[info ] - Please check the node logs to see if the node successfully connects to the server.
[info ] - To see the logs, run: v6 node attach --name node1

Now the node container is running, but it does not mean the node is connected to the server. You need to check the logs to see if the node successfully connects to the server.

Watch the logs


You can show the logs in the current console by running the command:

BASH

v6 node attach --name node1

then it will print out the logs of the node in the console:

BASH

From there, you can see the running status of the node, the connection to the server, the databases, the websocket connection, and the incoming tasks.

Challenge 2: Start a node and watch the logs

  1. Start the node node2 you created in last exercise using the v6 node start command.
  2. Watch the logs of the node using the v6 node attach --name node2 command. Observe the logs and see if the node is connected to server successfully.
  3. How do you know if the node is connected to the server without checking the logs?
  1. You can use vantage6 UI to check if a node is online or not. There are two ways:
    • Click on the Nodes tab in the administration page, then click on the tab of the node you want to check. You will see the node status is Online if the node is connected to the server successfully.
    • Or click on the Collaborations tab in the administration page, then click on the tab of the collaboration you want to check. You will see the Nodes section, if nodes are in green color, it means they are online, otherwise they are in red color with a message Offline.

Stop a node


To stop a running node, you can run the command:

BASH

v6 node stop

then it will ask you which node you want to stop:

BASH

? Select the node you wish to stop: (Use arrow keys)
 » vantage6-node1-user

after you choose the node, it will print out the following messages:

BASH

? Select the node you wish to stop: vantage6-node1-user
[info ] - Stopped the vantage6-node1-user Node.

Update the API key of your node


Reset API key for a node via the vantage6 UI

If you want to reset the API key for a node, you can do so by following these steps:

  1. Login to the vantage6 UI.
  2. Click on the Nodes tab in the administration page.
  3. Click on the tab of the node you want to reset the API key for in the list of nodes.
Reset API key for a node
Reset API key for a node
  1. Click on the Reset API key button.
    • You may see a dialog box asking you to download the new API key.
Download new API key
Download new API key

You will see a message:

API key download

Your API key has been reset. Please read your new key in the file that has been downloaded.

You can open the downloaded text file to copy the new API key. Next, you’ll use it to update your node configuration.

Update API key in the node configuration file

You can use v6 CLI to update the API key of a node. For that, you can run the command:

BASH

v6 node set-api-key

then it will ask you which node you want to update the API key of:

BASH

? Select the configuration you want to use: (Use arrow keys)
 » node1
   node2

after you choose the node, it will ask you to enter the new API key, then you can paste the new API key you just copied from the downloaded file:

BASH

? Select the configuration you want to use: node1

[info ] - Your new API key has been uploaded to the config file ***/vantage6/node/node1.yaml.

When you finish the process, the node configuration file will be updated with the new API key.

To make the new API key effective, you need to restart the node by running the command v6 node stop and then v6 node start.

Challenge 3: Update the API key of a node

  1. Reset the API key of the node node2 you created in the first exercise.
  2. Update the API key of the node node2, WITHOUT using the v6 node set-api-key command.
  3. How do you verify that the new API key is effective?
  1. You can go to the Nodes tab in the administration page, then click on the tab of the node you want to reset the API key for, and click on the Reset API key button.
  2. We can update the API key in the configuration file:
  • Run the v6 node files command to locate the configuration file.
  • Open the configuration file and write the new API key in the api_key field.
  • Stop the node with the v6 node stop command.
  • Restart the node with the v6 node start command.
  1. In order to verify the effectiveness of the API key change, we can restart the node with active logging:

BASH

v6 node start --attach

In the log, we have to look for the node authentication message:

BASH

2024-05-30 14:41:13 - common         - DEBUG    - Authenticating node...
2024-05-30 14:41:13 - common         - INFO     - Successfully authenticated

Run a task on the nodes


Now start all your nodes and go to the vantage6 UI to create a new task for your nodes.

Challenge 4: Run a task on the nodes

Start all your nodes node1 and node2 and go to the vantage6 UI to run a new task for your nodes using the Average algorithm for the age data.

  1. Run a centralized task on the nodes.
  2. Run a federated task on the nodes.

v6 server and v6 algorithm-store commands

In this lesson we have focussed on the CLI commands to manage the vantage6 node. Note that the commands to manage the server (v6 server) and the algorithm store (v6 algorithm-store) are similar to the ones presented for the node. However, they are less commonly used for production scenarios where administrators often prefer to deploy via nginx or docker compose. We will not cover those commands in this course.

Key Points

  • Install the vantage6 CLI package by running pip install vantage6.
  • Use the v6 --help command to see the available commands of the vantage6 CLI.
  • Use the v6 node command to manage the vantage6 node instances.
  • Use the v6 node new command to create a new node configuration.
  • Use the v6 node start command to start a node.
  • Use the v6 node attach --name xxx command to show the logs of the node xxx.
  • Use the v6 node stop command to stop a node.
  • Use the v6 node set-api-key command to set a new API key of a node.
  • Use the v6 node files command to check the location of the node configuration file.
  • The commands similar to the ones presented for the node are also available for v6 server and v6 algorithm-store.
