Add SSH keys to VMs


This document describes how to add SSH keys to virtual machine (VM) instances that use OS Login and VMs that use metadata-based SSH keys. If you or your organization administrator hasn't enabled OS Login, your VMs use metadata-based SSH keys.

Before you begin

  • For information about managing access to your Compute Engine VMs, see Choosing an access method.
  • If you haven't already, create an SSH key pair.
  • If you haven't already, then set up authentication. Authentication is the process by which your identity is verified for access to Google Cloud services and APIs. To run code or samples from a local development environment, you can authenticate to Compute Engine by selecting one of the following options:

    Select the tab for how you plan to use the samples on this page:

    Console

    When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.

    gcloud

    1. Install the Google Cloud CLI, then initialize it by running the following command:

      gcloud init
    2. Set a default region and zone.

    Terraform

    To use the Terraform samples on this page in a local development environment, install and initialize the gcloud CLI, and then set up Application Default Credentials with your user credentials.

    1. Install the Google Cloud CLI.
    2. To initialize the gcloud CLI, run the following command:

      gcloud init
    3. If you're using a local shell, then create local authentication credentials for your user account:

      gcloud auth application-default login

      You don't need to do this if you're using Cloud Shell.

    For more information, see Set up authentication for a local development environment.

    REST

    To use the REST API samples on this page in a local development environment, you use the credentials you provide to the gcloud CLI.

      Install the Google Cloud CLI, then initialize it by running the following command:

      gcloud init

    For more information, see Authenticate for using REST in the Google Cloud authentication documentation.

Add keys to VMs that use OS Login

VMs that use OS Login accept SSH keys that are associated with your Google Account. You can associate a public SSH key with your Google Account using the gcloud CLI or using the OS Login API. If you're an administrator for your organization, you can add SSH keys to user accounts using the Directory API.

When you add SSH keys to your Google Account, Compute Engine generates a username for you by combining the username and domain from the email associated with your Google Account. For example, if your email address is cloudysanfrancisco@gmail.com, your username is cloudysanfrancisco_gmail_com. If you add an SSH key in a project that is outside of your organization, your username is prefixed with ext_, for example, ext_cloudysanfrancisco_gmail_com. Your organization administrator can customize your username using the Directory API. If you already have a username configured, Compute Engine uses that username when you add SSH keys.

gcloud

  1. In the Google Cloud console, activate Cloud Shell.

    Activate Cloud Shell

    At the bottom of the Google Cloud console, a Cloud Shell session starts and displays a command-line prompt. Cloud Shell is a shell environment with the Google Cloud CLI already installed and with values already set for your current project. It can take a few seconds for the session to initialize.

  2. To add a public SSH key to your account, use the gcloud compute os-login ssh-keys add command:

    gcloud compute os-login ssh-keys add \
       --key-file=KEY_FILE_PATH \
       --project=PROJECT \
       --ttl=EXPIRE_TIME
    

    Replace the following:

    • KEY_FILE_PATH: the path to the public SSH key on your workstation. The key must use the public-openssh format
    • PROJECT: Optional: a project where you intend to use your SSH key. Specify this field to use your SSH key in a project outside of your organization, or you are not a member of a Cloud Identity organization
    • EXPIRE_TIME: Optional: the expiration time for the SSH key

      For example, if you specify 30m the SSH key expires after 30 minutes.

      This flag uses the following units:

      • s for seconds
      • m for minutes
      • h for hours
      • d for days

Terraform

To add a public SSH key to your account, use the google_client_openid_userinfo resource along with the google_os_login_ssh_public_key resource.

data "google_client_openid_userinfo" "me" {
}

resource "google_os_login_ssh_public_key" "default" {
  user = data.google_client_openid_userinfo.me.email
  key  = file("id_rsa.pub") # path/to/ssl/id_rsa.pub
}

REST

To add a public SSH key to your account, use the OS Login API users.importSshPublicKey method:

POST https://oslogin.googleapis.com/v1/users/ACCOUNT_EMAIL:importSshPublicKey

{
 "key": "SSH_KEY",
 "expirationTimeUsec": "EXPIRATION_TIMESTAMP"
}

Replace the following:

  • ACCOUNT_EMAIL: the email address associated with your account
  • SSH_KEY: the public key that you want to add to the account
  • EXPIRATION_TIMESTAMP: the expiration time for the key, in microseconds since epoch (1 second = 106 microseconds)

Add SSH keys to VMs that use metadata-based SSH keys

VMs that don't use OS Login store SSH keys in Compute Engine project and instance metadata. If OS Login is enabled for a VM, then the VM's guest agent ignores the keys stored in metadata.

You can use SSH keys stored in project metadata to access all VMs in a project. You can use SSH keys stored in instance metadata to access individual VMs.

Compute Engine doesn't automatically remove expired SSH keys from metadata at expiration time, but expired keys can't be used to establish new connections to VMs. If you want to remove expired keys from metadata, see Remove SSH keys from VMs that use metadata-based keys.

You can add a public SSH key to project or VM instance metadata using the Google Cloud console, the gcloud CLI, or REST.

Add SSH keys to project metadata

You can add a public SSH key to project metadata to access all VMs in a project, except VMs that block project-wide SSH keys. For more information about blocking project-wide SSH keys, see Block SSH keys from VMs that use metadata-based SSH keys.

Console

To add a public SSH key to project metadata using the Google Cloud console, do the following:

  1. In the Google Cloud console, go to the Metadata page.

    Go to Metadata

  2. Click the SSH keys tab.

  3. Click Edit.

  4. Click Add item.

  5. In the SSH key field that opens, add your public SSH key. The key must be in one of the following formats:

    • Format for a key without an expiration time:

      KEY_VALUE USERNAME
    • Format for a key with an expiration time:

      KEY_VALUE google-ssh {"userName":"USERNAME","expireOn":"EXPIRE_TIME"}

    Replace the following:

    • KEY_VALUE: the public SSH key value
    • USERNAME: your username. For example, cloudysanfrancisco or cloudysanfrancisco_gmail_com.

      For Linux VMs, the USERNAME can't be root, unless you configure your VM to allow root login. For more information, see Connect to Linux VMs as the root user.

      For Windows VMs that use Active Directory (AD), the username must be prepended with the AD domain, in the format of DOMAIN\. For example, the user cloudysanfrancisco within the ad.example.com AD has a USERNAME of example\cloudysanfrancisco.

    • EXPIRE_TIME: the time the key expires, in ISO 8601 format. For example: 2021-12-04T20:12:00+0000
  6. Click Save.

gcloud

In the Google Cloud console, activate Cloud Shell.

Activate Cloud Shell

At the bottom of the Google Cloud console, a Cloud Shell session starts and displays a command-line prompt. Cloud Shell is a shell environment with the Google Cloud CLI already installed and with values already set for your current project. It can take a few seconds for the session to initialize.

  1. If there are existing SSH keys in project metadata, you must re-add them to project metadata every time you add a new SSH key using the gcloud CLI. If you don't re-add your existing keys, adding a new key erases the existing keys.

    To add a public SSH key to project metadata using the gcloud CLI, do the following:

    1. If your project already has project-wide public SSH keys, get them from metadata and add them to a new file:

      1. Run the gcloud compute project-info describe command to get the SSH keys for the project:

        gcloud compute project-info describe \
         --format="value(commonInstanceMetadata[items][ssh-keys])"
        

        The output is similar to the following:

        username:ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQ... username:ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQ...
        
      2. Copy the ssh-keys metadata value.

      3. Create and open a new text file on your workstation.

      4. In the file, paste the list of keys that you just copied.

      5. Add your new key at the end of the list, in one of the following formats:

        • Format for a key without an expiration time:

          USERNAME:KEY_VALUE
        • Format for a key with an expiration time:

          USERNAME:KEY_VALUE google-ssh {"userName":"USERNAME","expireOn":"EXPIRE_TIME"}

        Replace the following:

        • KEY_VALUE: the public SSH key value
        • USERNAME: your username. For example, cloudysanfrancisco, or cloudysanfrancisco_gmail_com.

          For Linux VMs, the USERNAME can't be root, unless you configure your VM to allow root login. For more information, see Connecting to instances as the root user.

          For Windows VMs that use Active Directory (AD), the username must be prepended with the AD domain, in the format of DOMAIN\. For example, the user cloudysanfrancisco within the ad.example.com AD has a USERNAME of example\cloudysanfrancisco.

        • EXPIRE_TIME: the time the key expires, in ISO 8601 format. For example: 2021-12-04T20:12:00+0000
      6. Save and close the file.

    2. Run the gcloud compute project-info add-metadata command to set the project-wide ssh-keys value:

      gcloud compute project-info add-metadata --metadata-from-file=ssh-keys=KEY_FILE
      

      Replace KEY_FILE with one of the following:

      • The path to the file you created in the previous step, if the project had existing SSH keys
      • The path to your new public SSH key file, if the project didn't have existing SSH keys

Terraform

To add a public SSH key to your project metadata, use the google_compute_project_metadata resource.

resource "google_compute_project_metadata" "default" {
  metadata = {
    ssh-keys = <<EOF
      dev:ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILg6UtHDNyMNAh0GjaytsJdrUxjtLy3APXqZfNZhvCeT dev

    Replace the following:

    • PROJECT_ID: your project ID
    • EXISTING_SSH_KEYS: the value of the ssh-keys key from the response of the instances.get request
    • FINGERPRINT: the fingerprint from the response of the projects.get request
    • NEW_SSH_KEY: the new SSH key, in one of the following formats:

      • Format for a key without an expiration time:

        USERNAME:KEY_VALUE
      • Format for a key with an expiration time:

        USERNAME:KEY_VALUE google-ssh {"userName":"USERNAME","expireOn":"EXPIRE_TIME"}

      Replace the following:

      • KEY_VALUE: the public SSH key value
      • USERNAME: your username. For example, cloudysanfrancisco, or cloudysanfrancisco_gmail_com.

        For Linux VMs, the USERNAME can't be root, unless you configure your VM to allow root login. For more information, see Connecting to instances as the root user.

        For Windows VMs that use Active Directory (AD), the username must be prepended with the AD domain, in the format of DOMAIN\. For example, the user cloudysanfrancisco within the ad.example.com AD has a USERNAME of example\cloudysanfrancisco.

      • EXPIRE_TIME: the time the key expires, in ISO 8601 format. For example: 2021-12-04T20:12:00+0000
