run_migrations.sh auto-discovers numbered SQL files (NN_*.sql), tracks applied migrations in tracksolid.schema_migrations table, and skips already-applied files — safe to run on every deployment. Usage: bash /app/run_migrations.sh Coolify: add to Post-deployment Command in service settings. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# run_migrations.sh — Tracksolid DB Migration Runner
|
|
# ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
|
# Applies any pending numbered SQL migration files in order.
|
|
# Safe to run on every deployment — skips already-applied migrations.
|
|
#
|
|
# Usage:
|
|
# ./run_migrations.sh # auto-detect container + DB
|
|
# ./run_migrations.sh --dry-run # show what would run, don't apply
|
|
#
|
|
# Called by Coolify post-deployment command:
|
|
# bash /app/run_migrations.sh
|
|
#
|
|
# How it tracks applied migrations:
|
|
# Creates tracksolid.schema_migrations table on first run.
|
|
# Records the filename of every successfully applied migration.
|
|
# Skips any file already recorded in that table.
