What its author says it does
Copied from the file, not written here
Use when the user wants to create, list, stop, remove, or troubleshoot isolated Docker-only WordPress version test labs on an SSH-reachable host (such as a Synology NAS) — older WordPress installs, side-by-side WordPress containers, or WordPress/PHP compatibility checks run with docker compose. Also use to set or change the saved connection/identity config the skill uses.

Rubicon WordPress Version Lab
Create and manage isolated Docker Compose WordPress test labs on an SSH-reachable host. Each lab is its own Compose project (separate WordPress + MariaDB + WP-CLI containers) on a shared external network, so multiple WordPress versions run side by side.
First-run configuration
The skill keeps no infrastructure details in its files. Connection and identity values live in a local config outside the repo at ~/.config/rubicon-wp-lab/config.env (mode 600), managed by scripts/config_wp_lab.sh.
On first use, if config_wp_lab.sh --show reports no config, gather SSH host (an ssh alias or user@host) and access host (the hostname/IP the user browses to — it becomes the WordPress site URL), then save them:
scripts/config_wp_lab.sh --set --ssh-host <host> --access-host <host>
Optional saved defaults: --base-parent (default /volume1/docker), --network (default wordpress_lab_default), --admin-user (default admin), --admin-email, --tz (default UTC), --umask (default 002). Change any later with another --set; inspect with --show; remove with --reset --confirm.
Required workflow (create)
- Ensure config exists (above). Any saved value can be overridden per run with the matching flag.
- Gather or infer:
--site-name: short lowercase slug (container/project prefix).--wp-version: exact WordPress version, e.g.6.4.5,5.9.10,4.9.26.--php-version: passautoto recommend fromreferences/wordpress-php-compatibility.md, or set explicitly.--port: passautoto find a free port (8080–8999), or set explicitly.
- Run
scripts/create_wp_lab.sh. It returns the lab URL, the credentials path on the NAS, and management commands.
Commands
| Action | Command |
|---|---|
| Configure / reconfigure | scripts/config_wp_lab.sh --set ... · --show · --path · --reset --confirm |
| Create a lab | scripts/create_wp_lab.sh --site-name <slug> --wp-version <ver> [--php-version auto] [--port auto] |
| List labs | scripts/list_wp_labs.sh |
| Stop a lab | scripts/stop_wp_lab.sh --site-name <slug> |
| Remove a lab | scripts/remove_wp_lab.sh --site-name <slug> --confirm |
create_wp_lab.sh --help lists every override flag.
Safety rules
- Never delete or overwrite an existing lab unless the user explicitly asks.
createrefuses to overwrite an existingcompose.yamlwithout--force, and backs it up (timestamped) before overwriting. removedeletes the lab's containers, database, and files; it requires--confirm.- Passwords are generated randomly (unless overridden), transferred inside a private per-run staging directory (never on a command line), and stored only in the lab's
credentials.txton the NAS at mode 600. - Published ports bind to all interfaces on the NAS. Never expose old WordPress labs publicly — warn the user to keep router/firewall rules closed. These are local compatibility labs.
- Treat very old WordPress/PHP combinations as best effort: old official Docker tags may be missing for the host's CPU architecture. Note such deviations as Needs Verification.
Troubleshooting
Use references/troubleshooting.md for config, SSH/Docker access, image-pull, WP-CLI, permission, port, and site-URL issues.
