Ruby 2.6.3 has been EOL since March 2022 and Gemstash 2.8.0 now requires Ruby >= 3.1, making this a good time to modernize the stack. Key changes: - Ruby 2.6.3 -> 3.4 (via ruby:3.4-alpine) - Gemstash 2.0.0 -> 2.8.0 - pg 0.18.4 -> 1.6.3, mysql2 0.5.2 -> 0.5.7, puma 3.12.6 -> 7.2.0 - MySQL image 5.7.19 -> 8.0, PostgreSQL image 9.6.3 -> 16 - Add yaml-dev for psych gem native extension - Fix postgres volume mount path (/var/lib/mysql -> /var/lib/postgresql/data) - Remove deprecated compose version key and links directive Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Create /home/gemstash/data with correct ownership before VOLUME directive, fixing "Base path is not writable" error - Switch MySQL compose to MariaDB 11, since Alpine's mariadb-dev provides MariaDB Connector C which has SSL incompatibilities with MySQL 8.0's caching_sha2_password + self-signed certs - Update healthcheck to use mariadb CLI and MARIADB_* env vars Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
