Notes

Enable debugging of packed apps

chrome://flags#debug-packed-apps

Chrome storage API:

chrome.storage.sync: Chrome Account == Google Account

chrome.storage.managed: Need some sort of Google Apps license -> too complex.

Remote Desktop

Remote desktop is currently not available for unattended chrome boxes. We need to use the remote assistance feature, requiring us to read off a string of numbers from the Chrome OS screen in order to connect to the session.

Auto-update

o Checks for updates every "several hours" "you can force an update using the Extensions page's Update extensions now button."

manifest: "update_url" key

Chrome Developer Dashboard

Hosting

Self-hosting: https://developer.chrome.com/extensions/hosting

Private Publishing

Kiosk Apps

NB! Kiosk Apps cannot be privately published (since Kiosk sessions don't have a login to verify against). It's possible to publish unlisted instead.

  • chrome://extensions
  • Manage kiosk applications -> Add kiosk application -> paste application ID -> Add -> Done

Kiosk Mode

  • To set up Kiosk Mode, we need to wipe the Chromebox/Chromebit: Recovery button + Ctrl-D * 2: https://support.google.com/chrome/a/answer/1360642
  • On reboot: space+Enter, select network
  • At login screen: Ctrl-Alt-K
  • Sign in as usual
  • When setting up a Kiosk App, we can now make it auto-start. On the first subsequent reboot we need to confirm this.
  • It's possible to cancel auto-launch by pressing Ctrl-Alt-S on startup

Developer Mode

NB! It's not possible to switch back from Developer Mode without wiping the Chrome Box

  • Press Power while holding Recovery Button
  • On boot screen, press Ctrl-D
  • Press Recovery again
  • Press Ctrl-D again -> Will wipe local data

Notes:

  • Ctrl-Alt-F2 : Switches to Terminal
  • There is no default root password
  • In an interactive session, Ctrl-Alt-t brings up a console
    • 'shell' opens a full bash shell

ssh server

Server keys:

mkdir -m 0711 /mnt/stateful_partition/etc/ssh
cd /mnt/stateful_partition/etc/ssh
ssh-keygen -t rsa -f ssh_host_rsa_key
ssh-keygen -t dsa -f ssh_host_dsa_key

Server:

/usr/sbin/sshd
iptables -I INPUT -p tcp --dport 22 -j ACCEPT

Remote debugging

Persisting data

  • Data stored using chrome.storage.local will persist
  • NB! After writing any data, it's important to perform a software reload using chrome.runtime.reload(), otherwise stored data will/may not persist.

Recover a damaged Chrome OS

The "black-flicker" issue is a symptom

https://support.google.com/chromebook/answer/1080595?hl=en

NB! It's not always possible to wipe a damaged Chrome OS (Ctrl-D on the revovery screen just won't work)

Questions

  • How to allow quit/restart from within Chrome app (without having to power toggle) -> chrome.runtime.reload();
