CI/CD Integration

The ZETIC Melange CLI can be integrated into your CI/CD pipeline to automate model deployment whenever your model is retrained or updated.

Overview

A typical CI/CD workflow with Melange:

Train or update your model in your ML pipeline.
Export the model to a supported format (.pt2 or .onnx).
Use the Melange CLI to upload the new model version.
The Melange backend compiles and optimizes the model.
Your app automatically picks up the new version on next launch.

Setup

Install the CLI

pip install zetic

Authentication

For CI/CD environments, authenticate using environment variables or a pre-authenticated session:

# Interactive login (run once to cache credentials)
zetic auth login

Store your Personal Key as a CI/CD secret environment variable for automated workflows.

Example Pipeline

GitHub Actions

name: Deploy Model
on:
  push:
    paths:
      - 'models/**'

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Set up Python
        uses: actions/setup-python@v5
        with:
          python-version: '3.10'

      - name: Install ZETIC CLI
        run: pip install zetic

      - name: Deploy model
        env:
          ZETIC_PERSONAL_KEY: ${{ secrets.ZETIC_PERSONAL_KEY }}
        run: |
          zetic auth login
          zetic gen \
            -p ${{ vars.REPOSITORY_NAME }} \
            -i models/input.npy \
            models/model.onnx

General CI/CD Script

#!/bin/bash
set -e

# Install CLI
pip install zetic

# Authenticate
zetic auth login

# Upload model
zetic gen \
  -p username/model-name \
  -i input_0.npy \
  -i input_1.npy \
  model.pt2

echo "Model deployment initiated successfully"

Best Practices

Version your inputs alongside your model files.
Use separate repositories for staging and production models.
Monitor deployment status on the Melange Dashboard after upload.
Pin model versions in production apps to avoid unintended updates.

Ensure your CI/CD environment has network access to the Melange API endpoints. The CLI requires internet connectivity for authentication and model upload.
