need to set and test my web-app using Google cloud compute engine. How do I connect to an Instance Using ssh on Ubuntu Linux or Apple OS X based system?

Generate Ssh Key Google Compute Engine Console

By default, you can always connect to an instance using ssh. This is useful so you can manage and configure your instances beyond the basic configuration enabled by gcutil or the REST API. The easiest way to ssh into an instance is to use gcutil command from your local Linux / OS X based systems. The following steps are required
Advertisements
  1. Install gcutil/google sdk
  2. Authorize instance
  3. Verify instance status
  4. Create ssh keys
  5. Connect using gcutil or ssh client

Step #1: Install gcutil

gcutil runs on UNIX-based operating systems such as Linux and Mac OS X. To use gcutil, you must have Python 2.6.x or 2.7.x installed on your computer. gcutil does not support Python 3.x. Python is installed by default on most Linux distributions and Mac OS X. Open the Terminal and type the following command or to grab gcutil tool visiting this url.

Debian / Ubuntu / RHEL / CentOS Linux/OS X UNIX user type the following commands:

Open a terminal and type:
## Download IT ##
$ wget https://dl.google.com/dl/cloudsdk/release/google-cloud-sdk.tar.gz
$ tar -zxvf google-cloud-sdk.tar.gz
## INSTALL IT ##
$ bash google-cloud-sdk/install.sh
Sample outputs:

See how to install gcutil tool to manage Google Compute Engine on Linux / Unix for more information.

Step #2: Authenticating to Google Compute Engine

The syntax is:

If your project id is “apache-cluster”, enter:

Sample outputs:
Open a web browser, and go to the specified URL. Click the Grant Access link. The page will display an authorization code. Copy this code. Paste the authorization code into the waiting gcutil auth terminal and press enter. Type the following command to cache project-id:

Step #3: Verify instance status

Type the following command:
$ gcloud compute instances list
Sample outputs:

Note: instance-1 instance running in asia-east1-c zone.

Step #4: Create ssh keys

The syntax is:

In this example, connect to db1 instance using ssh:
$ gcloud compute ssh db1

gcutil creates local files to store your public and private key, and copies your public key to the project. By default, gcutil stores ssh keys in the following files on your local system:

  • $HOME/.ssh/google_compute_engine – Your private key
  • $HOME/.ssh/google_compute_engine.pub – Your public key

Step #5: Connect using gcutil or ssh client

The syntax is:

OR

How To Generate Ssh Key Pair

In this example, connect to the ‘instance-1’ instance using gcloud tool:

Sample outputs:

In this example, connect to the db1 (public ip 1.2.3.4) instance using ssh command:

Sample sessions:

To SSH into ‘db3’ in zone asia-east1-c, run:
gcloud compute ssh db3 --zone asia-east1-c

You can also run a command on the virtual machine. For example, to get a snapshot of the guest’s process tree, run:
gcloud compute ssh db3 --zone asia-east1-c --command 'ps -ejH'

If you are using the Google container virtual machine image, you can SSH into one of your containers with:
gcloud compute ssh db3 --zone asia-east1-c --container CONTAINER

How do I login as root user?

For security reasons, the standard Google do not provide the ability to ssh in directly as root. The instance creator and any users that were added using the –authorized_ssh_keys flag or the metadata sshKeys value are automatically administrators to the account, with the ability to run sudo without requiring a password. Type the following command to switch to root user:

Optional: Update your gcloud tools

Type the following command:

  • Google Compute Engine documentation.
  • Man pages: bash(1)
