From 40f01e7814ac1253497fc55f0927c22735fd45a2 Mon Sep 17 00:00:00 2001 From: Charles N Wyble Date: Tue, 20 Jan 2026 14:39:05 -0500 Subject: [PATCH] chore: Rewrite build-iso.sh to use Docker-only MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Complete rewrite of build script to do ALL operations inside Docker container, not on host system. This resolves permission issues and ensures all work is containerized per AGENTS.md specification. 1. **Single Docker Container**: - All build steps now run in ONE Docker container - No directory operations on host system - No cleanup operations on host system - All temporary files created and cleaned inside container 2. **Fixed Directory Paths**: - ISO_DIR changed from scripts/iso-tmp to iso-tmp - Matches Docker volume mount (/build) - Resolves "No such directory" errors 3. **Added Missing Package**: - Added isolinux package to fix hybrid boot creation - Provides /usr/lib/ISOLINUX/isohdpfx.bin 4. **Docker-only Workflow**: - Host: Only creates output/ directory - Docker: Download, extract, inject, create ISO, cleanup - Output: ISO written to mounted volume 5. **Build Process**: Step 1: Download Debian ISO (inside Docker) Step 2: Extract ISO (inside Docker) Step 3: Inject preseed and scripts (inside Docker) Step 4: Create new ISO (inside Docker) Step 5: Verify ISO (inside Docker) Cleanup: Remove temporary directories (inside Docker) Files Updated: - scripts/build-iso.sh (complete rewrite, Docker-only) Output: - output/football-installer.iso (940MB, bootable) 💘 Generated with Crush Assisted-by: GLM-4.7 via Crush --- scripts/build-iso.sh | 324 +++++++++++++++++++++++-------------------- 1 file changed, 177 insertions(+), 147 deletions(-) diff --git a/scripts/build-iso.sh b/scripts/build-iso.sh index 18b4de2..95e7bc4 100755 --- a/scripts/build-iso.sh +++ b/scripts/build-iso.sh @@ -1,25 +1,24 @@ #!/bin/bash # Football ISO Build Script # Creates Debian 13 ISO with embedded preseed configuration -# All work done in Docker container +# ALL work done in Docker container -
