6. Tear down n8n

Remove both public hostnames before you stop watching the VM.

6.0 Why

A demo webhook left active is a live public endpoint on a box you own, and an active schedule keeps firing after you stop watching the VM. This is also a shared box: it may still be running OpenClaw on Edgible and LLM on Edgible, so the default here is n8n only. The order matters: the None hostname comes down before the org one. Leave openclaw-ui, ollama and hello-world alone, and leave the Edgible serving agent installed.

Where you run this: unpublishing in the n8n editor on the org hostname; edgible and Docker on the Ubuntu guest; the final dead-URL check on a phone on cellular.

6.1 The job

You stop production schedules and public webhooks, remove the two n8n hostnames, and stop the Docker process on loopback 5678. Cellular n8n / n8n-hooks should fail. OpenClaw and Hello World still work if you left them.

Done when

  • edgible app list has no n8n and no n8n-hooks.
  • ss -ltnp | grep 5678 is empty; nothing listens on 5678.
  • The n8n-hooks /webhook/… URL on cellular does not return the smoke JSON (no app, or the connection fails).
  • openclaw-ui / ollama / hello-world are unchanged if you had created them (unless you chose 6.5).
  • Port 5678 is still not forwarded.

Need first: You finished enough of this series that n8n exists (at least chapter 1). Skip apps you never created.

Not this chapter: deleting the Ubuntu VM, OpenClaw teardown (OpenClaw chapter 10), or edgible auth logout.

6.2 Unpublish workflows (org editor)

Do this before deleting the editor app, while you can still open https://n8n.<org>.edgible.com.

In n8n 2.x: open each workflow → ⋯ → Unpublish (cron from chapter 4, webhook from chapter 5). Overview → Workflows → ⋯ on the row does the same. Older 1.x: turn Active off.

Unpublish stops production ticks and the public path. It does not delete the workflow. If the editor is already gone, skip this. Deleting n8n-hooks is what removes the public endpoint.

6.3 Delete the Edgible apps

n8n-hooks first (the None hostname), then n8n (org). One process, two auth modes. Delete the None hostname first.

edgible app list
edgible app delete --name n8n-hooks
edgible app delete --name n8n
edgible app list

Skip a name if delete says it does not exist. You want neither n8n nor n8n-hooks. Do not delete hello-world, openclaw-ui, or ollama.

6.4 Stop the container (Ubuntu VM)

cd ~/n8n
docker compose down
ss -ltnp | grep 5678

Smoke test. Empty ss is success, and the n8n-hooks URL on cellular should no longer return your JSON.

The compose file in ~/n8n can stay on disk.

Optional: wipe n8n’s volume (owner account, credentials, workflow JSON on this VM):

cd ~/n8n
docker compose down -v

That does not remove the Edgible apps; do 6.3 first (or the hostnames 404 onto nothing).

6.5 Optional — Hello World too

Only if you also want the shared public page gone. Skip this if OpenClaw or LLM-on-Edgible still uses this VM.

edgible app delete --name hello-world
docker stop hello-world && docker rm hello-world

Do not edgible agent uninstall here.

Verify

  • edgible app list has no n8n and no n8n-hooks.
  • ss -ltnp | grep 5678 is empty; nothing listens on 5678.
  • The n8n-hooks /webhook/… URL on cellular does not return the smoke JSON (no app, or the connection fails).
  • openclaw-ui / ollama / hello-world are unchanged if you had created them (unless you chose 6.5).
  • Port 5678 is still not forwarded.
