FL Server Create

💡 Overview

This guide walks you through creating a task and running the FL Server using the MNIST example.

Differences from FedOps 1.1.2

  1. In 1.1.2, the FL server ran as a Kubernetes Job, so it terminated when an FL run finished, making post-run management and log inspection difficult. Code was managed via Git, which made debugging and fixes harder. In 1.2, the server runs as a Pod with dedicated resources for the FL server, making code management, debugging, and log inspection much easier.
  2. In 1.1.2, there were no management features for the FL server, so resource scaling and file browsing were not possible. In 1.2, you can scale resources, browse files, and execute commands, making server management easier.
  3. When creating a task, options are collected from the user and applied automatically, preventing typos and missing required fields in the initial config.

Steps

  1. To create an FL server, first create a task in the FedOps web UI.

  3. Click Create Scalable Server to create the FL server.

    1. By default, the Scalable Server is provisioned with 1 CPU and 2 Gi of memory. You can change these in Resource Scaling and apply them with Scale Resources.

    2. Once server creation starts successfully, the FL Status will change. (Click Refresh Status to update the status.)

  4. You can check the environment setup logs via Server Logs. When setup completes, the FL Status shows “FL Server created.” (Click Refresh Logs to update the logs.)

  5. The created server’s file structure is as follows. models.py and data_preparation.py include default MNIST example code. conf/config.yaml is populated with the options you set when creating the task.
     app/code/
 ├── client_main.py
 ├── client_manager_main.py
 ├── data_preparation.py
 ├── models.py
 ├── server_main.py
 ├── requirements.txt
 └── conf
     └── config.yaml

  6. Click Start FL Server to launch the FL Server.

    1. The FL server’s runtime logs are saved to /app/data/logs/serverlog.txt. Use File Content to view the server’s logs.
    2. Stop FL Server terminates the running FL Server process.
