Easy Google Collab SSH Tunnel

• Run this script and enjoy a free GPU/High Memory machine courtesy of Google.
• Adapted from this stackoverflow answer which was adapted from this gist
• This is useful if:
  • You want a Free GPU
  • You want a more robust dev env than the collab notebooks. (i use this to run juptyer lab instances)
  • You have low memory on your computer so even running Google Collab in browser is slow.

Usage:

• Create an NGROK account
• Create file .env file with the following fields and upload it to your collab notebook:

authtoken=NGROK AUTH TOKEN
instancepw=SSH INSTANCE PASSWORD

Launching an Instance

• Open up a collab notebook and clone this repository
• To launch an SSH instance
  • run !bash bootup.sh
• To launch an SSH instance with a bootstrap script.
  • run !bash bootup.sh [PATH TO BOOTSTRAP SCRIPT]
• Use ssh commands outputted in the collab notebook cell.

TODO:

• Add support for using google drive file system.
• Add bootstrap for Spark dev
• Look into ways to mitigate collab notebook shutdown
• Add example collab notebook
