🤖 Automation & CLI Support (NEW)

Every script can now run non-interactively — perfect for CI pipelines, configuration management, and batch provisioning:

Script	Mode / Flags	Purpose
`devops.ps1` / `devops.sh`	`install` \| `uninstall` \| `update` \| `status` \| `info` \| `verify` \| `logs` \| `doctor` \| `export` \| `upgrade`	Run any launcher action and exit — no menu
`devops.ps1`	`-NoUpdateCheck`, `-Yes`	Skip the startup update check / auto-confirm prompts
`devops.sh`	`-s` (`--skip-update`), `-h` (`--help`)	Skip update check / show usage
`install_devops_tools.ps1`	`-List`, `-Install Terraform,Git`, `-All`, `-DryRun`, `-Reinstall`, `-Upgrade`, `-Profile <file>`, `-PackageManager winget`, `-SkipRequirements`	Non-interactive installs
`install_devops_tools.sh`	`-l`, `-i "docker,terraform"`, `-a`, `-d` (`--dry-run`), `-s`/`-p`, `-j N`, `-r` (`--retry-failed`), `-U` (`--upgrade`), `--from <file>`, `--skip-requirements`	Non-interactive installs
`uninstall_devops_tools.ps1`	`-List`, `-Uninstall Docker,Terraform`, `-All`, `-DryRun`, `-Force`	Non-interactive uninstallation
`uninstall_devops_tools.sh`	`-l`, `-u "docker,terraform"`, `-a`, `-d` (`--dry-run`), `-f` (`--force`)	Non-interactive uninstallation

💡 Privileges: elevation is only enforced for actions that change the system — read-only actions (status, info, verify, logs, doctor, export, -DryRun, -List) run as a normal user.

🌐 Cross-Platform Compatibility

🐧 Linux Distribution Support – Ubuntu, Debian, CentOS, RHEL, Fedora, Arch, Alpine, SUSE
🪟 Windows Support – Windows 10/11 with PowerShell 5.0+ and Chocolatey
📦 Package Manager Detection – Automatic detection of apt, yum, dnf, pacman, zypper, apk, choco
🔧 Service Management – systemd, init.d, Windows service support
🌍 Internationalization – Multi-language error messages and logging

📌 Supported DevOps Tools

The catalog below is exactly what the scripts install/uninstall (run -List / -l on the installer any time for the authoritative list):

🔹 Containerization & Orchestration

🔹 Infrastructure as Code & Automation

✔️ Terraform | ✔️ Ansible | ✔️ Packer | ✔️ Vagrant

🔹 CI/CD & Version Control

✔️ Jenkins 🤵 | ✔️ GitLab Runner | ✔️ Git | ✔️ ArgoCD | ✔️ Flux

🔹 Cloud Providers & CLI Tools

✔️ AWS CLI | ✔️ Azure CLI | ✔️ Google Cloud SDK (gcloud)

🔹 Monitoring & Observability

✔️ Prometheus 🔥 | ✔️ Grafana 📊 | ✔️ K9s 🐕

🔹 Service Mesh & Security

✔️ HashiCorp Vault 🔐 | ✔️ HashiCorp Consul 🕸️

🪟 Windows note: the PowerShell installer uses Chocolatey packages — a few catalog entries have Windows-specific package ids (e.g. gcloudsdk, istioctl) and Windows services (Jenkins, Prometheus, Grafana) are not started as services. The universal state file keeps both platforms in sync.

🛠️ Installation Guide

🚀 Method 1: One-Liner (Quick Install)

📌 Windows (PowerShell):

iwr -useb https://raw.githubusercontent.com/NotHarshhaa/DevOps-Tool-Installer/main/devops.ps1 | iex

📌 Linux (Bash):

curl -s https://raw.githubusercontent.com/NotHarshhaa/DevOps-Tool-Installer/main/devops.sh | bash

These combined launchers (devops.ps1 and devops.sh) automatically guide you to install or uninstall tools via an interactive prompt!

Security Note: The one-liner downloads and executes the script. For security-conscious environments, use Method 2.

Method 2: Clone the Repository

Linux

git clone https://github.com/NotHarshhaa/DevOps-Tool-Installer.git  
cd DevOps-Tool-Installer  
chmod +x devops.sh  
./devops.sh

Windows

git clone https://github.com/NotHarshhaa/DevOps-Tool-Installer.git  
cd DevOps-Tool-Installer  
.\devops.ps1

Security Note: Always review scripts before execution, especially in production environments.

🔍 Method 3: Manual Download (Recommended for Security)

Download the script manually:
- Windows: devops.ps1
- Linux: devops.sh
Verify the script contents (security best practice)
Execute with appropriate permissions:
- Windows: powershell -ExecutionPolicy Bypass -File devops.ps1
- Linux: chmod +x devops.sh && sudo ./devops.sh

🤖 Method 4: Non-Interactive / Automation (CI-Friendly)

Skip the menus entirely — ideal for scripts, pipelines, and cloud-init:

📌 Linux examples

# Install specific tools without prompts (parallel by default)
sudo scripts/install_devops_tools.sh -i "docker,terraform"

# Install everything, sequentially, limited to 8 parallel jobs
sudo scripts/install_devops_tools.sh -a -s -j 8

# Preview what would be installed (dry run, no changes)
sudo scripts/install_devops_tools.sh -d -i "kubernetes-cli,helm"

# Re-install tools recorded as failed in the state file
sudo scripts/install_devops_tools.sh -r

# Uninstall tools without prompts (force), preview first (dry run)
sudo scripts/uninstall_devops_tools.sh -u "docker,terraform" -f
sudo scripts/uninstall_devops_tools.sh -d -u "docker,terraform"

# Install tools from a shareable profile file (workstation-as-code)
./devops.sh export                                          # save installed tools to profiles/devops_profile.txt
sudo scripts/install_devops_tools.sh --from profiles/devops_profile.txt

# Upgrade only the tools that are already installed
sudo ./devops.sh upgrade

# Launcher one-shot actions
./devops.sh status
./devops.sh verify
./devops.sh logs
./devops.sh doctor

📌 Windows examples

# Install specific tools without prompts
powershell -File scripts\install_devops_tools.ps1 -Install Terraform,Git

# Install everything (already-installed tools are skipped automatically)
powershell -File scripts\install_devops_tools.ps1 -All

# Preview a plan (no changes), or reinstall over existing tools
powershell -File scripts\install_devops_tools.ps1 -DryRun -Install Git
powershell -File scripts\install_devops_tools.ps1 -Reinstall -Install Git

# Uninstall tools without prompts, or list them first
powershell -File scripts\uninstall_devops_tools.ps1 -Uninstall Docker,Terraform
powershell -File scripts\uninstall_devops_tools.ps1 -List

# Export installed tools to a shareable profile, and re-apply it anywhere
.\devops.ps1 export
powershell -File scripts\install_devops_tools.ps1 -Profile profiles\devops_profile.txt

# Upgrade only the tools that are already installed
.\devops.ps1 upgrade

# Launcher one-shot actions
.\devops.ps1 status
.\devops.ps1 verify
.\devops.ps1 logs
.\devops.ps1 doctor

Additionally, interactive tool menus accept multi-select: enter 3, a range like 1-5, a list like 2,4, or all — l re-lists the catalog (Windows), and the Linux menus show the same numbering across runs (categories are sorted for stable numbering).

🛡️ Security Requirements

Windows: PowerShell 5.0+ ; Administrator privileges required for install/uninstall actions (read-only actions — status, info, verify, logs, -DryRun, -List — run as a normal user)
Linux: Bash 4.0+ ; root/sudo required for install/uninstall actions (jq, curl required for update checks, verified automatically)
Network: Internet connection for downloads and updates
Disk: Minimum 10GB free space for installations
TLS: TLS 1.2 support for secure connections

❌ Uninstallation Guide

🧹 This tool supports clean uninstallation with:

✅ Interactive selection with installed-status detection ([Installed] / [Not Found])
✅ Multi-select and range selection (3, 1-5, 2,4, all installed)
✅ Advanced cleanup (services, configs, logs, binaries, even APT/Choco package purge)
✅ Dry run mode on both platforms (-d / --dry-run on Linux, -DryRun on Windows)
✅ Forced non-interactive runs (-f / --force on Linux, -Force on Windows)
✅ Timestamped logs saved in the logs/ folder

🔧 CLI examples

# Linux: preview, then remove specific tools without prompts
sudo scripts/uninstall_devops_tools.sh -d -u "docker,terraform"
sudo scripts/uninstall_devops_tools.sh -u "docker,terraform" -f

# Linux: remove every tool detected as installed
sudo scripts/uninstall_devops_tools.sh -a

# List the catalog with installed status
sudo scripts/uninstall_devops_tools.sh -l

# Windows: list tools with installed status, then uninstall without prompts
powershell -File scripts\uninstall_devops_tools.ps1 -List
powershell -File scripts\uninstall_devops_tools.ps1 -Uninstall Docker,Terraform

# Dry run, or remove every detected tool
powershell -File scripts\uninstall_devops_tools.ps1 -DryRun -Uninstall Docker,Terraform
powershell -File scripts\uninstall_devops_tools.ps1 -All

🔧 Linux & macOS

Use the universal launcher:

curl -s https://raw.githubusercontent.com/NotHarshhaa/DevOps-Tool-Installer/main/devops.sh | bash

🔧 Windows

Use PowerShell launcher:

iwr -useb https://raw.githubusercontent.com/NotHarshhaa/DevOps-Tool-Installer/main/devops.ps1 | iex

🧭 After running the launcher, you'll be prompted with an 8-option menu:

Install Tools
Uninstall Tools
Check for Updates
View Installation Status
System Information
Verify Installed Tools – re-checks every tool recorded in the state file against PATH
View Recent Logs – tail the manager, installer, and uninstaller logs
Exit

Optionally run any of these directly without the menu (install, uninstall, update, status, info, verify, logs, doctor, export, upgrade).
