Nvm, I found out you can add a commandline argument to the profiles section. For anybody else trying to figure this out:

{
       "guid": "{*add_a_guid*}",
       "name": "Google Cloud Shell",
       "commandline": "ssh -i *path_to_ssh_key* *username*@*ip_address*",
       "icon": "C:\\Program Files (x86)\\Google\\Cloud SDK\\cloud_platform_logo.ico",
       "hidden": false
}

You can generate a guid in PowerShell using this command:

[guid]::NewGuid()

TL;DR: No by using Powershell but yes using normal CMD.

You can use command gcloud alpha cloud-shell ssh to open a new session from Powershell to your cloud shell instance using SDK Shell (CMD). Before running the command, be sure that you have installed Cloud SDK for windows so you will be able to ssh to your Cloud Shell instance.

Regarding Powershell, unfortunatelly based on Cloud Tools for PowerShell cmdlet reference accessing (ssh) the Cloud Shell using Powershell is not yet supported. You can create a Feature Request in Google Cloud Issue Tracker to request this feature to be added to Powershell.

If your instance is running and you can restart it you may try logging in via serial console. This method is independed from any firewall / network settings :)

Just add a user with a password; create a startup script like this (it will create a user and add it to google-sudoers group so you can do everything with this account):

#! /bin/bash
adduser username
echo 'sudouser:userspass' | chpasswd
usermod -aG google-sudoers sudouser

And then connect to serial console you can log in. Either using console window or cloud shell: gcloud compute connect-to-serial-port instance-name

This will allow you to log in. Unless there's something really wront with your VM.

But - judging from you desription - you want regular SSH access.

For that make sure that:

• you firewall rules don't block port 22 on this machine
• your firewall on a VM in question allows traffic on port 22
• your ethernet interface is up in the VM
• SSH server listens (ps aux | grep sshd) on port 22

Then check if your VM has external IP - if not you will be only able to connect to your VM via another that has one, or via cloud shell (and of course serial console as described above).

However - since you got this Permission denied (publickey) message that means that for some reason your SSH keys don't work (corrupted, deleted etc). When you log in with serial console check if they're there. If not you can add them manually.

----------- UPDATE ------------

Look at this line: Jul 2 12:19:02 INSTANCE google_accounts_daemon[822]: gpasswd: /etc/group.####: No space left on device - it says that your VM ran out of disk space. Stop your VM, try resizing your VM's disk first with gcloud compute disks resize mydiskname --size=100GB --zone=us-central1-a and start it. After the start VM's partition will be resized. –

"Quickstart for Windows" is a good starting point for new users of Cloud SDK.

In order to deploy and run a GAE application with the Cloud SDK you have to use shell/command prompt, as opposed to GoogleAppEngineLauncher where you had a GUI. The steps are:

1. Open the shell
2. In the shell change the current directory to where your project's app.yaml. is. For example: CD C:\Users\AQueue\Projects\MyGAEApplication and check that app.yaml file is there using dir command.
3. run gcloud app deploy

This should be it.

gcloud is one of the most important tools in the SDK that allows to interact with many products and services from Google Cloud Platform. If you want to read more about gcloud you can start with this overview.
