Add Once Apps: Campfire, Writebook, Fizzy

[Copilot]

Packages three open-source Once/37signals apps as EdgeApps: Campfire (team chat), Writebook (web-based e-book publishing), and Fizzy (Kanban project management).

New Apps

• Campfire — ghcr.io/basecamp/once-campfire:latest · requires SECRET_KEY_BASE · optional VAPID keys for Web Push · accessible at campfire.local
• Writebook — ghcr.io/basecamp/writebook:latest · no required config · accessible at writebook.local
• Fizzy — ghcr.io/basecamp/fizzy:main · requires SECRET_KEY_BASE · optional SMTP, VAPID, and BASE_URL · accessible at fizzy.local

Structure

Each app follows the standard EdgeApp conventions:

File	Purpose
Dockerfile	Wraps upstream GHCR image with OCI metadata
edgebox.env	App metadata; all marked EDGEAPP_EXPERIMENTAL=true
edgebox-compose.yml	Service definition with VIRTUAL_HOST, VIRTUAL_PORT: 80, DISABLE_SSL: "true" for nginx-proxy routing
edgebox-hosts.txt	Local mDNS subdomain
edgeapp.template.env	User-configurable options (Campfire & Fizzy only)
.dockerignore	Excludes appdata/ from build context

All three apps mount persistent storage at ./appdata/storage:/rails/storage.

# Example: campfire/edgebox-compose.yml (pattern shared across all three)
campfire-ws:
  environment:
    VIRTUAL_HOST: ${LOCAL_URL}${INTERNET_URL}
    VIRTUAL_PORT: 80
    DISABLE_SSL: "true"
    SECRET_KEY_BASE: '${CAMPFIRE_SECRET_KEY_BASE}'
  volumes:
    - ./appdata/storage:/rails/storage:rw

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• once.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_title>Add Once Apps (Campfire, Writebook, Fizzy)</issue_title>
<issue_description>Add the following apps (part of Once, Open Source), to be packaged as EdgeApps.

The apps are:

• Campfire, a teams chat (slack replacement).
• Writebook (Write and share e-books online)
• Fizzy (Project management done simple)</issue_description>

<agent_instructions>Make sure to follow the conventions available in other EdgeApps.
Check the hello app for a very barebones version, and take it from there to implement these apps.

Search the internet for the Dockerfiles of these apps.
Pause work if unsure how to continue and ask.</agent_instructions>
