Free Linux cloud shell for Gmail users – shell in the browser that works in all locations I’ve been so far

Posted by jpluimers on 2020/05/18

This is still so cool: [WayBack] Free Linux cloud shell for Gmail users … – Adrian Marius Popa – Google+:

Free Linux cloud shell for Gmail users

comments are more interesting

“If you want a free Linux box with a Public IP and SSH, I’d recommend spinning up an f1-micro VM. It’s part of the permanent free tier”

https://news.ycombinator.com/item?id=16248668

Even cooler is that you can use it both from a web browser and from your own console, more on that below.

Cloud Shell from the web

The above links:

I still need to use the f1-micro VM instance (my cloud and self hosted stuff is in different locations), but the cloud shell has saved my butt for so many times by now that I lost count.

Basically the shell worked everywhere I tried, where stuff like shellinabox [WayBack], anyterm [WayBack] or [WayBack] ajaxterm/qweb [WayBack] fail.

Each time you logon, you will be connected to a VM, so it takes a few seconds while you see

Establishing connection to your Google Cloud Shell

If you have not used it for a while, then it takes a bit longer as some provisioning needs to take place which can take about a minute at slow times:

Provisioning your Google Cloud Shell machine... Since you haven't used your Cloud Shell for a while, it may take some time to unarchive your disk.

Provisioning your Google Cloud Shell machine… Since you haven’t used your Cloud Shell for a while, it may take some time to unarchive your disk.

After 60 minutes of inactivity, it will disconnect:

Your Google Cloud Shell session was idle for over 60 minutes and terminated.

Your Google Cloud Shell session was idle for over 60 minutes and terminated.

 

Like a regular ssh client, the [WayBack] Secure Shell – Chrome Web Store Terminal emulator and SSH client fails in many situations because a lot of places block outgoing traffic over other ports than http (TCP port 80) and https (TCP port 443).

Cloud Shell from the MacOS console

Shortly after the Google Cloud Shell announcement, access got extended beyond the web interface: [WayBack] Google Cloud Platform Blog: Introducing the ability to connect to Cloud Shell from any terminal.

That page only shows how you use console access to the Google Cloud Shell, not how to install it. So below are the installation instructions on a Mac with MacOS/Mac OS X/OS X.

Installing the console client for Google Cloud Shell access.

The easiest way to install the console client is by using homebrew [WayBack] and running these commands (a detailed gist with output is at the end)

brew install caskroom/cask/google-cloud-sdk
gcloud alpha
gcloud alpha cloud-shell ssh
gcloud auth login
gcloud alpha cloud-shell ssh

Somehow this fails. See the log below.

The Cloud Shell runs on an f1-micro VM instance

If you are contemplating about using an f1-micro VM instance, it pays to know that the Cloud Shell runs on one (see the “log” in the “about” below).

A few years ago, the OpsDash people did some analysis on what performance the f1-micro VM actually provides  [WayBack] Exploring the Google Cloud f1-micro Instance – OpsDash did.

From the “about” the Cloud Shell shows that it consists of.
