prerequisites

name	prerequisites
description	CLI tool prerequisites validation and setup. USE FOR: validate prerequisites, check CLI tools, install missing tools, verify versions, prerequisite checklist. DO NOT USE FOR: deployment orchestration (use deploy-orchestration), Terraform operations (use terraform-cli), Kubernetes operations (use kubectl-cli).

When to Use

• Before any deployment workflow
• Environment setup validation
• CI/CD pipeline prerequisite checks

Prerequisites

• Bash shell
• Access to download tools if missing

Required CLI Tools

Tool	Minimum Version	Purpose
az	2.50.0	Azure CLI
terraform	1.5.0	Infrastructure as Code
kubectl	1.28.0	Kubernetes CLI
helm	3.12.0	Kubernetes package manager
gh	2.30.0	GitHub CLI
argocd	2.8.0	ArgoCD CLI
jq	1.6	JSON processor
yq	4.0.0	YAML processor

Validation Script

#!/bin/bash
set -euo pipefail

# Check required tools
TOOLS=("az" "terraform" "kubectl" "helm" "gh" "argocd" "jq" "yq")
MISSING=()

for tool in "${TOOLS[@]}"; do
  if ! command -v "$tool" &> /dev/null; then
    MISSING+=("$tool")
  fi
done

if [ ${#MISSING[@]} -ne 0 ]; then
  echo "Missing tools: ${MISSING[*]}"
  exit 1
fi

echo "All prerequisites satisfied"

Installation Commands

macOS (Homebrew)

brew install azure-cli terraform kubectl helm gh argocd jq yq

Ubuntu/Debian

# Azure CLI
curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

# Terraform
wget -O- https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list
sudo apt update && sudo apt install terraform

# kubectl
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

Best Practices

1. Run prerequisite check before every deployment
2. Pin tool versions in CI/CD
3. Document version requirements
4. Use version managers (asdf, mise)
5. Include prerequisite check in pre-commit hooks

Output Format

1. Tools checked
2. Versions found
3. Missing tools
4. Installation instructions
