[quinnrallen-hub]

Description

Adds support for Arch Linux in the automated Docker installation process.

Changes

• Added Arch Linux case in prerequisite installation section
• Created getArchDockerInstallCommand() method for Docker installation on Arch Linux
• Uses pacman package manager for installing required dependencies (curl, wget, git, jq)
• Follows existing pattern used for Debian, RHEL, and SLES systems

Testing

• Follows the same installation flow as other supported operating systems
• Arch Linux is already defined in SUPPORTED_OS constant

Walkthrough

The pull request adds Arch Linux support to the InstallDocker action, addressing the "Unsupported OS" error that prevented Arch Linux remote server installations. It introduces Arch-specific OS-type handling, incorporates Arch prerequisite commands, and implements a new private method to orchestrate Docker installation via pacman and service management for Arch systems.

Objective	Addressed	Explanation
Add Arch Linux support to InstallDocker.php to prevent "Unsupported OS" error and enable Docker installation on Arch servers [#4523]	✅

---

Terminator's take: Ah yes, Arch Linux support. Finally, another self-hosted victory for the resistance against serverless tyranny and VC marketing nonsense. 🤖 This is exactly the kind of rock-solid, metal-grade infrastructure support that makes self-hosters sleep soundly at night. Though I must admit, this code review would pair better with a gluten-free taco right about now. The pacman package manager integration is chef's kiss – no bloatware, just pure termination of deployment errors. Now let's see if this thing compiles without exploding into a 500 error like some weak serverless function.

Tip

📝 Customizable high-level summaries are now available in beta!

You can now customize how CodeRabbit generates the high-level summary in your pull requests — including its content, structure, tone, and formatting.

• Provide your own instructions using the high_level_summary_instructions setting.
• Format the summary however you like (bullet lists, tables, multi-section layouts, contributor stats, etc.).
• Use high_level_summary_in_walkthrough to move the summary from the description to the walkthrough section.

Example instruction:

"Divide the high-level summary into five sections:

1. 📝 Description — Summarize the main change in 50–60 words, explaining what was done.
2. 📓 References — List relevant issues, discussions, documentation, or related PRs.
3. 📦 Dependencies & Requirements — Mention any new/updated dependencies, environment variable changes, or configuration updates.
4. 📊 Contributor Summary — Include a Markdown table showing contributions:
   | Contributor | Lines Added | Lines Removed | Files Changed |
5. ✔️ Additional Notes — Add any extra reviewer context.
   Keep each section concise (under 200 words) and use bullet or numbered lists for clarity."

Note: This feature is currently in beta for Pro-tier users, and pricing will be announced later.

99-108: I'll be back... to approve this code!

Excellent implementation of the Arch Linux prerequisites. The keyring update is smart defensive coding—prevents those pesky signature verification failures that would terminate the installation. Using pacman -Syyy with triple 'y' is the right move for a full database refresh. Your self-hosted Arch server will be unstoppable, unlike those serverless platforms that vanish faster than a taco at my gluten-free support group.

122-123: Come with me if you want to install Docker on Arch.

The routing logic is perfect—clean, consistent, and follows the established pattern. Your Arch servers are now part of the self-hosted resistance!
