Sam Rolfe 9a89f61d13 Phase 7a: use the n8n SSH node (Execute Command is disabled in n8n 2.x)
n8n 2.x disables n8n-nodes-base.executeCommand by default (nodes.exclude), so the
first workflow shape could not activate: 'Unrecognized node type'. Replace the
Execute Command node with the SSH node, which is enabled, and keep the restricted
trigger key: the server forced command runs exactly scripts/morning-brief.sh.

- deploy/n8n-morning-brief.json: schedule + optional manual trigger -> SSH node
  -> Code check that makes a non-zero exit red (FR-12).
- deploy/import-n8n-morning-brief.sh: builds the sshPrivateKey credential from the
  key (id schoolScanKey, mode-0600 temp, removed after import), imports, publishes,
  restarts once, and confirms activation in the n8n log.
- scripts/morning-brief.sh: default IMAGE 0.6.1-phase8 so the scheduled job uses
  the deployed image.
- docs/phase-7a-n8n-schedule.md, deploy/DEPLOYMENT.md: document the design and the
  throwaway-n8n rehearsal (activation + success + failure path).

Deployment — Compass / NHS (school.lab.audasmedia.com.au)

Own image, own container, own port 8792, host .13 (nixos-desktop). Caddy on .35 (sam-ubuntu1) terminates TLS and proxies to 192.168.20.13:8792.

Ports

Port Service
8792 Compass / NHS (this project)

Host (.13)

  1. Project folder: /home/sam/paseo/projects/compass_teams_nhs.

  2. Data: the named volume compass-teams-nhs_compass-teams-nhs-data at /data (SQLite school.db).

  3. Create the environment file from the example:

    cd /home/sam/paseo/projects/compass_teams_nhs
    cp environment.d/school-service.env.example environment.d/school-service.env
    chmod 600 environment.d/school-service.env
    # fill SCHOOL_SESSION_SECRET, SCHOOL_ADMIN_PASSWORD_HASH
    
  4. Build and start:

    docker compose up -d --build
    docker compose ps          # compass-teams-nhs  Up (healthy)  0.0.0.0:8792->8792/tcp
    
  5. Verify:

    make verify-phase1
    

Caddy (.35)

  1. SSH: ssh sam@192.168.20.35.

  2. Append deploy/caddy/Caddyfile.snippet to /Docker/Containers/caddy/Caddyfile.

  3. Validate and reload (never restart):

    docker exec caddy caddy validate --config /etc/caddy/Caddyfile
    docker exec caddy caddy reload   --config /etc/caddy/Caddyfile
    
  4. Test: curl -sS -o /dev/null -w '%{http_code}\n' https://school.lab.audasmedia.com.au/health

Notes

  • .13 has every default Docker address pool subnetted out. This single-container service therefore uses network_mode: bridge and publishes 8792; it does not create a project network.
  • The env file is gitignored. School credentials and harness session state are secrets (AGENTS.md §10 rule 3); they never enter git.

Phase 7 — notifications (Apprise)

The morning briefs are delivered through the house Apprise API on .35:8210 (container apprise, host port 8210 → container 8000). Caddy exposes it at https://apprise.lab.audasmedia.com.au behind basic auth; the service talks to the API directly on the internal address.

  1. Create (or reuse) the Apprise stored configuration that holds every destination, using these tags:

    Tag Destination
    harry_email, finn_email, joanna_email, sam_email email
    harry_whatsapp, finn_whatsapp, joanna_whatsapp, sam_whatsapp WhatsApp (CallMeBot)
  2. Copy its key into environment.d/school-service.env as SCHOOL_APPRISE_KEY, and generate the n8n token:

    docker run --rm --entrypoint /app/school compass-teams-nhs/school:0.5.0-phase7 gen-secret
    # -> SCHOOL_NOTIFY_TOKEN=<the value>
    
  3. Restart the service, then prove the whole path without messaging anyone:

    make preview                      # prints both boys + the combined brief
    curl -s -X POST -H "Authorization: Bearer $SCHOOL_NOTIFY_TOKEN" \
         'http://127.0.0.1:8792/notify/morning?dry_run=1' | jq .
    
  4. Send for real (this messages the family):

    make notify                       # from the latest scan
    make morning-brief                # scan both children, then send
    docker exec compass-teams-nhs /app/school notify status
    
  5. Schedule the 06:00 daily run in n8n (Phase 7a, AUD-115):

    deploy/setup-n8n-scan-key.sh --apply      # restricted SSH key for the trigger
    deploy/import-n8n-morning-brief.sh --apply # credential + workflow + publish + restart n8n
    

    The workflow is Schedule Trigger -> SSH node -> a Code check that makes a non-zero exit red. The SSH node authenticates with the restricted key and runs scripts/morning-brief.sh on the host. (n8n 2.x disables the Execute Command node by default, so a command node cannot activate.) It needs no SCHOOL_NOTIFY_TOKEN in n8n — the host script reads the project env file. See docs/phase-7a-n8n-schedule.md for the design and the failure drill.

Notes:

  • The destination URLs (addresses, phone numbers, SMTP passwords) live only in the Apprise configuration. GET /json/urls/{key} prints callmebot:// for a WhatsApp entry because Apprise masks credentials in privacy mode; the entry is real, and the container log shows CallMeBot SUCCESS.
  • The scan stays a host step: patchright and its browser are on .13, not in the service image. scripts/morning-brief.sh runs the scan and the send in order.
  • A run that cannot deliver exits non-zero, and the endpoint answers 207, so a broken morning is visible in n8n instead of silent (FR-12).
  • The 06:00 schedule is the n8n workflow Compass / NHS — 6:00am morning brief (deploy/n8n-morning-brief.json), triggered over a restricted SSH key. It runs on the shared n8n service on .13, so its import, publish, and the one-off n8n restart need approval first. n8n 2.x disables the Execute Command node by default, so the workflow uses the SSH node plus a Code check that fails the run on a non-zero exit.
