Using Go Install

go install github.com/nghiadaulau/opsbrew@latest

Quick Start

  1. Initialize configuration:

    opsbrew --help
# This will create ~/.opsbrew.yaml with default settings

  2. Git operations:

    opsbrew git status          # Enhanced git status
opsbrew git sync           # git pull --rebase
opsbrew git checkout       # Fuzzy finder for branches

  3. Kubernetes operations:

    opsbrew k8s kctx           # Switch kubectl context
opsbrew k8s kns            # Switch namespace
opsbrew k8s klogs          # Get pod logs with fuzzy finder
opsbrew k8s khpa set-min my-hpa 2  # Set HPA min replicas
opsbrew k8s kscale deployment my-app 5  # Scale deployment

  4. Command recipes:

    opsbrew brew save daily-sync  # Save a new recipe
opsbrew brew run daily-sync   # Execute saved recipe
opsbrew brew list            # List all recipes

  5. File operations:

    opsbrew file backup config.yaml  # Create backup
opsbrew file find "*.yaml"       # Find files by pattern
opsbrew file diff file1.yaml file2.yaml  # Compare files

  6. Project templates:

    opsbrew init github-actions my-app    # Create GitHub Actions workflow
opsbrew init k8s-deployment my-app    # Create K8s Deployment
opsbrew init k8s-service my-app       # Create K8s Service
