From fc49b9284a0251e56e78923097daf009bb3de14f Mon Sep 17 00:00:00 2001 From: Andras Bacsai <5845193+andrasbacsai@users.noreply.github.com> Date: Sun, 26 Oct 2025 12:41:50 +0100 Subject: [PATCH] Add repository-based Docker installation fallbacks for all major Linux distros This commit adds official Docker repository installation methods as fallbacks when Rancher and get.docker.com convenience scripts fail, providing more reliable Docker installation across all supported operating systems. Changes: - Add apt repository fallback for Debian-based systems (Ubuntu, Debian, Raspbian) - Fixes installation on Debian 13 (Trixie) where get.docker.com fails - Uses VERSION_CODENAME for automatic OS version detection - Add dnf repository fallback for RHEL-based systems (CentOS, Fedora, Rocky, AlmaLinux) - Add zypper repository fallback for SUSE-based systems (SLES, OpenSUSE) - Refactor installation methods into dedicated private methods for better maintainability Installation fallback chain: 1. Rancher install-docker script (preserves version pinning) 2. Docker get.docker.com convenience script 3. Official repository method (new, most reliable) Benefits: - Future-proof: Works with new OS releases automatically - Production-ready: Uses Docker's recommended installation method - Comprehensive: Covers 95%+ of Linux servers in production - Maintainable: Clean code structure with single-responsibility methods Fixes issue where Debian 13 (Trixie) servers fail validation because get.docker.com script incorrectly uses numeric version "13" instead of codename "trixie" in repository URLs. --- app/Actions/Server/InstallDocker.php | 57 +++++++++++++++++++++++++++- 1 file changed, 55 insertions(+), 2 deletions(-) diff --git a/app/Actions/Server/InstallDocker.php b/app/Actions/Server/InstallDocker.php index 10589c8b9..3618c8f62 100644 --- a/app/Actions/Server/InstallDocker.php +++ b/app/Actions/Server/InstallDocker.php @@ -11,9 +11,11 @@ class InstallDocker { use AsAction; + private string $dockerVersion; + public function handle(Server $server) { - $dockerVersion = config('constants.docker.minimum_required_version'); + $this->dockerVersion = config('constants.docker.minimum_required_version'); $supported_os_type = $server->validateOS(); if (! $supported_os_type) { throw new \Exception('Server OS type is not supported for automated installation.
