Toast is a Python-based CLI utility with a plugin architecture that simplifies the use of CLI tools for AWS, Kubernetes, Git, and more. It provides a unified interface for common DevOps tasks and enhances productivity through interactive selection and streamlined workflows.

Key Features

• Plugin-based Architecture

  • Modular design for easy extensibility
  • Dynamic command discovery and loading
  • Simple plugin development model

• AWS Integration

  • IAM Identity Checking (toast am)
  • AWS Profile Management (toast env)
  • AWS Region Selection (toast region)
  • AWS SSM Parameter Store Integration (toast dot)

• Kubernetes Management

  • Context Switching (toast ctx)
  • EKS Cluster Integration

• Git Workflow

  • Repository Cloning and Management
  • Branch Creation
  • Pull Operations with Rebase Support

• Workspace Organization

  • Directory Navigation (toast cdw)
  • Environment File Management (toast dot)

• Interactive Interface

  • FZF-powered selection menus
  • Formatted JSON output with JQ

Plugin Architecture

Toast uses a plugin-based architecture powered by Python's importlib and pkgutil modules:

• Each command is implemented as a separate plugin that extends the BasePlugin class
• Plugins are automatically discovered and loaded at runtime
• Commands are registered with Click for consistent CLI behavior
• New functionality can be added without modifying existing code

See ARCHITECTURE.md for detailed information about the design and implementation.

Installation

Requirements

• Python 3.6+
• Click package for CLI interface
• External tools used by various plugins:
  • fzf: Interactive selection in terminal
  • jq: JSON processing for formatted output
  • aws-cli: AWS command line interface
  • kubectl: Kubernetes command line tool

Installation Methods

# Install from PyPI
pip install toast-cli

# Update to latest version
pip install --upgrade toast-cli

# Install specific version
pip install toast-cli==3.2.0

# Install development version from GitHub
pip install git+https://github.com/opspresso/toast-cli.git

# Install in development mode from local clone
git clone https://github.com/opspresso/toast-cli.git
cd toast-cli
pip install -e .

Creating Symbolic Link (Optional)

If toast command is not available in your PATH after installation:

# Create a symbolic link to make it available system-wide
sudo ln -sf $(which toast) /usr/local/bin/toast

Usage

# View available commands
toast --help

# Run a specific command
toast am           # Show AWS identity
toast cdw          # Navigate workspace directories
toast ctx          # Manage Kubernetes contexts
toast dot          # Manage .env.local files with AWS SSM integration
toast env          # Manage AWS profiles
toast git          # Manage Git repositories
toast region       # Manage AWS region
toast version      # Display the current version

Command Examples

# AWS Identity Management
toast am                   # Show current AWS identity

# Workspace Navigation
toast cdw                  # Interactive selection of workspace directories

# Kubernetes Context Management
toast ctx                  # Switch between Kubernetes contexts
                          # Select [New...] to add EKS clusters
                          # Select [Del...] to remove contexts

# Environment File Management
toast dot                  # Show .env.local status
toast dot up               # Upload .env.local to AWS SSM Parameter Store
toast dot down             # Download .env.local from AWS SSM Parameter Store
toast dot ls               # List all .env.local files in AWS SSM

# AWS Profile Management
toast env                  # Switch between AWS profiles

# Git Repository Management
toast git repo-name clone  # Clone a repository
toast git repo-name rm     # Remove a repository
toast git repo-name branch -b branch-name  # Create a new branch
toast git repo-name pull   # Pull latest changes
toast git repo-name pull -r  # Pull with rebase

# AWS Region Management
toast region               # Switch between AWS regions

Extending with Plugins

To add a new plugin:

1. Create a new Python file in the toast/plugins directory
2. Define a class that extends BasePlugin
3. Implement the required methods (execute and optionally get_arguments)
4. Set the name and help class variables

Example plugin:

from toast.plugins.base_plugin import BasePlugin
import click

class MyPlugin(BasePlugin):
    name = "mycommand"
    help = "Description of my command"

    @classmethod
    def get_arguments(cls, func):
        # Optional: Define command arguments
        func = click.option("--option", "-o", help="An option for my command")(func)
        return func

    @classmethod
    def execute(cls, **kwargs):
        # Command implementation
        option = kwargs.get("option")
        if option:
            click.echo(f"Executing with option: {option}")
        else:
            click.echo("My custom command execution")

The plugin will be automatically discovered and loaded when toast is run.

Recommended Aliases

Add these to your shell configuration file (e.g., .bashrc, .zshrc):

# Main alias
alias t='toast'

# Navigate workspace directories
c() {
  cd "$(toast cdw)"
}

# Common Command Aliases
alias m='toast am'      # Show AWS identity
alias x='toast ctx'     # Manage Kubernetes contexts
alias d='toast dot'     # Manage .env.local files
alias e='toast env'     # Manage AWS profiles
alias g='toast git'     # Manage Git repositories
alias r='toast region'  # Manage AWS region
