verti-osi 1.4.4

A CLI tool for generating OCI-compliant container images for Python and Node.js projects.

Verti-OSI CLI Tool Documentation

Overview

Verti-OSI is a command-line tool designed to generate OCI-compliant container images. It allows users to create container images from a specified project source directory while offering various customization options such as selecting the container runtime daemon, output type, and execution of the generated image.

Supported Languages

Currently, verti-osi supports Python and Node.js projects. The CLI automatically detects the language package manager and generates the appropriate container image.

Prerequisites

To use verti-osi, ensure the following:

• Python 3.7+ installed. Check with:

  python --version
  

• PIPX installed. Check with:

  pipx --version
  

  If missing, install it via:

  python -m pip install --user pipx
  pipx ensurepath
  

• A running container daemon (Docker or Podman).
  • Docker: Ensure the daemon is running:

    docker info
    

  • Podman: Ensure Podman is installed and running:

    podman info
    

Installation (via pipx)

To install verti-osi globally using pipx, run:

pipx install verti-osi

Usage

After installation, invoke the CLI tool using verti-osi. Below is the command structure and available options:

verti-osi --root-directory <path> \
          --source-directory <path> \
          --image-name <name> \
          --daemon <daemon-type> \
          --output <output-type> \
          --delete-generated-dockerfile <True/False> \
          --run-generated-image <True/False>

Command Parameters

• --root-directory (default: .) - The root directory of the project.
• --source-directory (default: .) - The directory containing the project’s source code.
• --image-name (required) - The name of the image to be generated.
• --daemon (default: docker) - The container runtime daemon to be used (docker or podman).
• --output (default: '') - The output type for the generated image. Supports tar, registry push, and standard image generation.
• --delete-generated-dockerfile (default: False) - If True, the generated Dockerfile will be deleted after image creation.
• --run-generated-image (default: False) - If True, the generated container image will be executed immediately.

Automatic Language Detection

verti-osi automatically detects the programming language based on the project structure:

• Python: If requirements.txt or pyproject.toml is found, the CLI generates a Python-based image.
• Node.js: If package.json is detected, the CLI generates a Node.js-based image.

Example Usage

1. Generating a container image

verti-osi --root-directory . \
          --source-directory ./src \
          --image-name nodey-js-verti:v1-normal

2. Generating and pushing an image to a registry

verti-osi --root-directory . \
          --source-directory ./src \
          --image-name my-repo/nodey-js-verti:v1 \
          --output registry

3. Generating an image and deleting the Dockerfile

verti-osi --root-directory . \
          --source-directory ./src \
          --image-name nodey-js-verti:v1 \
          --delete-generated-dockerfile True

4. Generating an image and running it immediately

verti-osi --root-directory . \
          --source-directory ./src \
          --image-name nodey-js-verti:v1 \
          --run-generated-image True

Development

If you wish to contribute or modify the tool, follow these steps:

1. Clone the repository:
