Greptile Summary

This PR fixes Eclair node crashes when opening channels by migrating the Docker images from Alpine Linux to Ubuntu Noble (Debian-based). The changes comprehensively update all Alpine-specific tooling to Debian equivalents across both the Dockerfile and entrypoint script.

Key changes:

• Base images updated from eclipse-temurin:25.0.1_8-jdk-alpine to eclipse-temurin:25.0.2_10-jdk-noble (build) and corresponding JRE images (runtime)
• Package management: apk → apt-get with proper cleanup of /var/lib/apt/lists/* for smaller image size
• User management: Alpine's adduser/addgroup → Debian's useradd/groupadd with appropriate flags
• Privilege dropping: su-exec → gosu for running as non-root user
• Added -p flags to mkdir commands for better idempotency

All changes are consistent and complete. The migration addresses the root cause of the channel opening crashes while maintaining compatibility with Polar's volume permission handling across different host platforms.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The migration from Alpine to Noble is complete, consistent, and addresses a specific bug. All Alpine-specific commands have been correctly updated to their Debian equivalents. The changes are isolated to Eclair Docker infrastructure and don't modify application logic. Image cleanup practices follow best practices.
• No files require special attention

Important Files Changed

Filename	Overview
docker/eclair/Dockerfile	Migrates from Alpine to Noble-based eclipse-temurin images, updates package manager commands from apk to apt-get, replaces su-exec with gosu, and improves mkdir commands with -p flag
docker/eclair/docker-entrypoint.sh	Updates user/group creation from Alpine syntax (adduser/addgroup) to Debian syntax (useradd/groupadd) and replaces su-exec with gosu
