File contents

Devcontainer Setup

The setup script forcefully resets all runtime state (services, tmpfs ramdisks, symlinks, log files) unconditionally on every run. Persistent DB/config content under /data is the one exception - it's preserved by default; see step 7 below.

Command

/workspaces/NetAlertX/.devcontainer/scripts/setup.sh

What It Does

Kills all services (php-fpm, nginx, crond, python3)
Mounts tmpfs ramdisks for /tmp/log, /tmp/api, /tmp/run, /tmp/nginx
Creates critical subdirectories
Links /entrypoint.d and /app symlinks
Creates /data, /data/config, /data/db directories
Creates all log files
Runs /entrypoint.sh to start services - by default this preserves existing DB/config content; entrypoint.d/25-first-run-db.sh and 20-first-run-config.sh only wipe them when ALWAYS_FRESH_INSTALL=true is set in the environment
Writes version to .VERSION

When to Use

After modifying setup scripts
After container rebuild
When environment is in broken state
To pick up a database/config reset done another way (setup.sh itself won't reset them - see step 7)

Philosophy

Runtime state (services, tmpfs, symlinks, logs) has no conditional logic - everything is recreated unconditionally, every run. DB/config are the one deliberate exception, gated behind ALWAYS_FRESH_INSTALL. If something in runtime state doesn't work, run setup again.
